Q1: A pregnant woman at 41 weeks of gestation is admitted for induction of labor. Her Bishop score is 3. Which intervention is most appropriate initially?

Correct Option: B

Rationale: A Bishop score of 5 or less indicates an unfavorable cervix, meaning induction with oxytocin alone is likely to fail. Cervical ripening (pharmacological or mechanical) must be done first to soften and efface the cervix.
NORCET TIP: A Bishop score >8 indicates a favorable cervix where oxytocin induction is highly successful.

Q2: Which of the following is a component of the Bishop score?

Correct Option: C

Rationale: The Bishop score assesses cervical readiness for labor. Its 5 components are: Cervical Dilation, Effacement, Consistency, Position, and Fetal Station.
NORCET TIP: Mnemonic for Bishop Score: “Call Every Cervix Perfect Score” (Consistency, Effacement, Cervical dilation, Position, Station).

Q3: The drug of choice for pharmacological cervical ripening in a post-term pregnancy with an intact uterus (no previous scar) is:

Correct Option: B

Rationale: Misoprostol (PGE1) and Dinoprostone (PGE2) are the preferred agents for cervical ripening. Ergometrine causes sustained tetanic contractions and is used only for PPH.
NORCET TIP: Misoprostol is strictly contraindicated in women with a previous cesarean section due to a high risk of uterine rupture.

Q4: The most significant adverse effect of Misoprostol when used for induction of labor is:

Correct Option: A

Rationale: Prostaglandins can cause uterine hyperstimulation/tachysystole (>5 contractions in 10 minutes), leading to fetal hypoxia and distress.
NORCET TIP: If tachysystole occurs with abnormal FHR, immediately position the mother laterally, give oxygen, give IV fluid bolus, and administer a tocolytic (e.g., Terbutaline).

Q5: A nurse is administering an IV oxytocin infusion for labor augmentation. Uterine tachysystole occurs, and the fetal heart rate drops to 90 bpm. What is the priority nursing action?

Correct Option: C

Rationale: The most direct and immediate action to stop the hyperstimulation causing fetal distress is discontinuing the offending agent (oxytocin). After stopping it, the nurse should reposition the mother and administer oxygen.
NORCET TIP: The half-life of oxytocin is very short (3-5 minutes), so stopping the infusion yields rapid clinical improvement.

Q6: What is the primary mechanism of action of a Foley bulb catheter in cervical ripening?

Correct Option: B

Rationale: The inflated balloon applies direct mechanical pressure to the internal os, separating the fetal membranes from the lower uterine segment, which stimulates local endogenous prostaglandin release.
NORCET TIP: Balloon catheters are preferred over prostaglandins for cervical ripening in women with a previous cesarean section (TOLAC).

Q7: Immediately after performing an amniotomy (artificial rupture of membranes), the priority nursing action is to:

Correct Option: C

Rationale: The sudden release of amniotic fluid can cause the umbilical cord to prolapse, leading to sudden fetal bradycardia. FHR must be assessed immediately.
NORCET TIP: Also document the color, odor, and amount of amniotic fluid (COAT) to rule out meconium staining or infection.

Q8: Which of the following is an absolute contraindication for the induction of labor?

Correct Option: C

Rationale: In placenta previa totalis, the placenta completely covers the internal cervical os. Labor and cervical dilation would cause massive, life-threatening hemorrhage. Delivery must be by Cesarean section.
NORCET TIP: Other absolute contraindications include vasa previa, transverse fetal lie, and active genital herpes.

Q9: The difference between induction of labor and augmentation of labor is that:

Correct Option: B

Rationale: Induction initiates labor artificially in a woman not in labor. Augmentation strengthens and coordinates contractions in a woman whose spontaneous labor is failing to progress.
NORCET TIP: Both procedures share similar risks, primarily tachysystole and fetal distress, requiring identical fetal monitoring.

Q10: While monitoring a patient on an oxytocin drip, the nurse notes prolonged uterine contractions lasting 120 seconds. This condition is termed:

Correct Option: B

Rationale: Tachysystole is >5 contractions in 10 minutes. Hypertonus (or tetanic contraction) is a single contraction lasting longer than 2 minutes, which severely compromises placental blood flow.
NORCET TIP: Both conditions fall under the umbrella of “uterine hyperstimulation” if accompanied by a non-reassuring FHR.

Q11: Dinoprostone is administered as a vaginal insert for cervical ripening. The nurse knows that a major advantage of the vaginal insert over the gel form is:

Correct Option: B

Rationale: The Dinoprostone vaginal insert (Cervidil) has a string attached, allowing for immediate removal if uterine tachysystole or fetal distress occurs, unlike gels or misoprostol tablets which cannot be easily retrieved.

Q12: High-dose, prolonged oxytocin administration can lead to which rare but severe maternal complication due to its structural similarity to ADH (vasopressin)?

Correct Option: B

Rationale: Oxytocin is biochemically similar to antidiuretic hormone (ADH). High doses infused in large volumes of electrolyte-free fluid can cause severe water retention, leading to dilutional hyponatremia and water intoxication.

Q13: According to ACOG and WHO guidelines, elective induction of labor without a medical indication should NOT be performed before:

Correct Option: B

Rationale: Elective induction prior to 39 weeks is contraindicated due to the significantly increased risk of neonatal respiratory morbidity (like TTN and RDS) and NICU admissions.

Q14: The most common fetal indication for the induction of labor is:

Correct Option: B

Rationale: Post-term pregnancy (reaching or exceeding 42 weeks) is the most frequent indication for induction to prevent placental insufficiency, oligohydramnios, and meconium aspiration syndrome.

Q15: The Bishop score component “Consistency” evaluates whether the cervix is:

Correct Option: B

Rationale: Cervical consistency changes from firm (like the tip of a nose) to soft (like the lips) as it ripens. A soft cervix scores higher (more favorable) on the Bishop scale.

Q16: What is the most appropriate timing to perform an episiotomy during a vaginal delivery?

Correct Option: C

Rationale: Episiotomy is performed during crowning (usually 3-4 cm of the head is visible) because the perineum is maximally thinned, reducing bleeding, and the tissue is naturally blunted to pain.
NORCET TIP: Performing it too early causes excessive blood loss; performing it too late fails to prevent perineal lacerations.

Q17: Compared to a median episiotomy, a mediolateral episiotomy has a higher risk of:

Correct Option: B

Rationale: Mediolateral episiotomies cut through more muscle and vascular tissue, leading to more bleeding, pain, and dyspareunia. However, they significantly reduce the risk of the tear extending into the anal sphincter (which is common in median episiotomies).
NORCET TIP: Mediolateral is the most commonly preferred type globally (especially in the UK/India) to prevent Obstetric Anal Sphincter Injuries (OASIS).

Q18: Which muscle is intentionally cut during a mediolateral episiotomy?

Correct Option: B

Rationale: The mediolateral episiotomy primarily cuts the vaginal epithelium, perineal skin, bulbospongiosus, and superficial transverse perineal muscles. The levator ani is generally spared.
NORCET TIP: The anal sphincter (external and internal) must NOT be cut. If it tears, it becomes a 3rd-degree perineal tear.

Q19: A post-delivery assessment reveals a perineal tear that involves the vaginal mucosa, perineal muscles, and the external anal sphincter, but the rectal mucosa is intact. How is this tear classified?

Correct Option: C

Rationale: 1st degree: Skin/mucosa only. 2nd degree: Muscles (perineal body) involved. 3rd degree: Anal sphincter complex involved. 4th degree: Extends through the sphincter into the rectal/anal mucosa.
NORCET TIP: 3rd and 4th-degree tears are known as Obstetric Anal Sphincter Injuries (OASIS) and require specialized repair in an operating room.

Q20: What is the recommended angle for a mediolateral episiotomy from the midline to minimize the risk of anal sphincter injury?

Correct Option: B

Rationale: Current evidence suggests an incision angle of 60 degrees from the midline when the perineum is distended provides the best clearance from the anal sphincter as the head descends.
NORCET TIP: An angle less than 45 degrees acts functionally like a median episiotomy, increasing the risk of OASIS.

Q21: Within the first 24 hours postpartum, the best nursing intervention to reduce edema and pain from an episiotomy wound is:

Correct Option: B

Rationale: Cold therapy (ice packs) causes vasoconstriction, which minimizes edema, hematoma formation, and numbs the area, providing immediate pain relief in the first 24 hours.
NORCET TIP: Warm sitz baths are recommended *after* 24 hours to promote circulation and healing.

Q22: A patient 12 hours post-episiotomy complains of severe, unrelenting perineal pain and rectal pressure that is not relieved by analgesics. The nurse should immediately suspect:

Correct Option: B

Rationale: Unrelenting, out-of-proportion perineal pain accompanied by a feeling of rectal pressure is the classic hallmark of a forming vulvar/vaginal hematoma, an obstetric emergency.
NORCET TIP: Inspect the perineum for unilateral swelling, bluish discoloration, and tenseness. Do not ignore severe perineal pain!

Q23: The ideal suture material for the repair of an episiotomy is:

Correct Option: C

Rationale: Rapidly absorbable synthetic sutures (like Vicryl Rapide) are preferred because they cause less tissue reaction and less pain than catgut, and they do not require removal.
NORCET TIP: Chromic catgut is largely obsolete for perineal repair in modern guidelines due to high inflammatory reaction and delayed healing.

Q24: A median (midline) episiotomy is absolutely contraindicated in which of the following scenarios?

Correct Option: A

Rationale: A short perineum (distance between the posterior fourchette and anus) increases the likelihood that a median incision will tear straight down into the anal sphincter. A mediolateral episiotomy is required here.
NORCET TIP: Median episiotomies are easier to repair and heal less painfully, but they carry an unacceptable risk of 3rd/4th degree tears in high-risk deliveries.

Q25: Which intervention during the second stage of labor is evidence-based for reducing the need for an episiotomy?

Correct Option: C

Rationale: Applying warm compresses and performing gentle perineal massage during the second stage improves tissue elasticity and reduces the incidence of perineal tears and the need for episiotomy.
NORCET TIP: Routine (prophylactic) episiotomy is no longer recommended; it should be restrictive, done only for specific indications (e.g., fetal distress, instrumental delivery).

Q26: Which type of episiotomy is cut directly downwards toward the anus?

Correct Option: C

Rationale: The median episiotomy begins at the posterior fourchette and extends straight down the midline toward, but not into, the anal sphincter.
NORCET TIP: It involves cutting the perineal body in the midline avascular plane, leading to minimal bleeding.

Q27: When assessing a post-episiotomy wound using the REEDA scale, the “D” stands for:

Correct Option: B

Rationale: REEDA stands for Redness, Edema, Ecchymosis, Discharge, and Approximation. It is a standard tool for assessing perineal wound healing.
NORCET TIP: Poor approximation (edges not meeting) or purulent discharge indicates wound breakdown or infection.

Q28: Which of the following is an absolute prerequisite for applying obstetric forceps?

Correct Option: B

Rationale: Attempting an instrumental delivery through a partially dilated cervix will result in massive cervical lacerations and severe maternal hemorrhage.
NORCET TIP: Prerequisites mnemonic: FORCEPS (Fully dilated, 0 station or lower, Ruptured membranes, Contractions adequate, Empty bladder, Presentation cephalic/vertex, Space adequate).

Q29: A “Low Forceps” delivery is classified when the leading point of the fetal skull is at what station?

Correct Option: C

Rationale: High forceps (above 0) and Mid forceps (0 to +1) are largely abandoned. Low forceps is from +2 station to just before crowning. Outlet forceps is when the scalp is visible at the introitus.
NORCET TIP: High forceps is never performed in modern obstetrics due to unacceptably high fetal and maternal morbidity; a cesarean section is done instead.

Q30: Which type of obstetric forceps is specifically designed for the delivery of an after-coming head in a vaginal breech delivery?

Correct Option: C

Rationale: Piper forceps have a long, backward-curving shank that allows them to be applied to the after-coming fetal head from below the fetal body during a breech delivery.
NORCET TIP: Simpson forceps are used for a molded head (primigravida), while Elliot forceps are used for an unmolded head (multigravida).

Q31: During a forceps delivery, the nurse observes that the forceps handles do not easily lock together after application. What does this indicate?

Correct Option: B

Rationale: Forceps handles are designed to articulate and lock smoothly. If they do not, it indicates improper placement (e.g., asymmetrical application over the face or neck), and they must be removed and reapplied.
NORCET TIP: Never use force to lock the handles, as this can crush the fetal skull.

Q32: A newborn delivered via forceps is observed to have an asymmetrical face when crying, with the right side of the mouth drooping. The nurse suspects:

Correct Option: B

Rationale: Pressure from the forceps blade on the fetal cheek (where the facial nerve exits the stylomastoid foramen) can compress the nerve, causing temporary unilateral facial paralysis (evident when crying).
NORCET TIP: Facial nerve palsy is typically unilateral and resolves spontaneously within a few days to weeks.

Q33: Before the application of obstetric forceps, the most important nursing action to prevent maternal visceral injury is:

Correct Option: B

Rationale: A full bladder is highly susceptible to rupture or trauma from the metal forceps blades as they are inserted and manipulated in the vagina. Catheterization is routinely performed.
NORCET TIP: Emptying the bladder also provides more room in the pelvis for fetal descent.

Q34: Kielland forceps are characterized by a sliding lock and a very slight pelvic curve. What is their primary obstetric function?

Correct Option: C

Rationale: The Kielland forceps lack a significant pelvic curve, which allows them to be rotated inside the maternal pelvis without the handles sweeping a wide arc that would damage the maternal tissues.
NORCET TIP: Rotational forceps deliveries are complex and carry a higher risk; they must only be performed by highly skilled obstetricians.

Q35: The direction of traction applied during a forceps delivery should follow the:

Correct Option: A

Rationale: Traction must follow the anatomical curve of the maternal pelvis (downward and outward, then upward) to facilitate delivery without causing severe maternal lacerations or pubic symphysis separation.
NORCET TIP: Traction is applied *only* during uterine contractions and in conjunction with maternal pushing.

Q36: Which of the following is a maternal indication for an elective forceps or vacuum delivery?

Correct Option: C

Rationale: In maternal conditions like cardiac disease, aneurysms, or severe preeclampsia, the Valsalva maneuver (pushing) is dangerous. Instrumental delivery is used to passively extract the baby (“cut short the second stage”).
NORCET TIP: Cephalopelvic disproportion and Placenta previa are indications for Cesarean section, not forceps.

Q37: Wrigley’s forceps are short and lightweight. They are specifically indicated for:

Correct Option: C

Rationale: Wrigley’s forceps have a short shank and handles, designed specifically for lifting the fetal head out when it is very low (outlet) or during a cesarean section. They cannot reach high into the pelvis.
NORCET TIP: Their short length acts as a safety feature, preventing the physician from generating excessive traction force.

Q38: Maternal complications of a difficult forceps delivery include all of the following EXCEPT:

Correct Option: D

Rationale: While forceps delivery increases the risk of lower genital tract trauma (lacerations, hematomas, sphincter tears), it is not a direct cause of amniotic fluid embolism (which is related to fluid entering maternal circulation).
NORCET TIP: Always inspect the vagina and cervix thoroughly post-forceps delivery to rule out hidden lacerations.

Q39: What type of forceps application is defined by the fetal skull being at the pelvic floor, with the scalp visible between contractions?

Correct Option: D

Rationale: Outlet forceps criteria: scalp is visible at the introitus without parting the labia, the fetal skull has reached the pelvic floor, and the head is at or on the perineum.
NORCET TIP: Outlet forceps are the safest and most commonly performed type of forceps delivery today.

Q40: When removing the forceps blades during delivery, when should the obstetrician take them off?

Correct Option: B

Rationale: Once the head is extended and crowning is complete, the forceps are carefully removed in the reverse order of application to avoid perineal tearing by the metal blades as the head emerges.
NORCET TIP: Forceps should never be kept on to deliver the shoulders.

Q41: What is the correct anatomical landmark for the placement of a vacuum extractor cup on the fetal head?

Correct Option: B

Rationale: Placing the cup at the flexion point ensures that when traction is applied, the fetal head remains maximally flexed, presenting the smallest diameter to the maternal pelvis.
NORCET TIP: Incorrect placement causes deflexion of the head, making delivery much harder and increasing the risk of fetal injury.

Q42: During a vacuum extraction, the cup detaches from the fetal head (“pops off”). According to standard guidelines, what is the maximum number of cup detachments allowed before abandoning the procedure?

Correct Option: B

Rationale: If the cup “pops off” 3 times (or 2 times in some strict protocols), the procedure must be abandoned and a cesarean section performed. Repeated pop-offs suggest cephalopelvic disproportion and drastically increase the risk of fetal scalp trauma.
NORCET TIP: The maximum overall duration of vacuum application should not exceed 20 to 30 minutes.

Q43: A common, transient scalp swelling that perfectly matches the shape of the vacuum cup is observed on a newborn. This is called a:

Correct Option: C

Rationale: A chignon is the artificial caput (scalp edema) created by the negative pressure of the vacuum cup. It is normal, benign, and resolves spontaneously within a few days.
NORCET TIP: Warn parents in advance about the chignon so they are not alarmed by the baby’s “cone head” appearance.

Q44: Which of the following is a strict contraindication for vacuum extraction?

Correct Option: B

Rationale: Vacuum extraction is contraindicated in preterm infants (usually <34 weeks) because their skulls are soft and their blood vessels are fragile, making them highly susceptible to fatal intracranial hemorrhage. Forceps are preferred if instrumental delivery is necessary.
NORCET TIP: Other contraindications include face/breech presentations and suspected fetal bleeding disorders (e.g., hemophilia).

Q45: Following a vacuum delivery, a newborn develops a fluctuant swelling on the head that crosses the cranial suture lines and is enlarging rapidly. The baby is tachycardic and pale. The nurse suspects:

Correct Option: C

Rationale: A subgaleal hemorrhage involves bleeding in the loose areolar tissue beneath the galea aponeurotica. It crosses suture lines, can hold the baby’s entire blood volume, and is a life-threatening complication of vacuum delivery.
NORCET TIP: Cephalohematoma involves bleeding strictly bounded by periosteal attachments (does NOT cross suture lines). Subgaleal crosses sutures and is an emergency.

Q46: When comparing vacuum extraction to forceps delivery, vacuum extraction has a higher risk of:

Correct Option: C

Rationale: Vacuum extraction is safer for the mother (less perineal trauma) but carries a slightly higher risk of specific fetal complications like cephalohematoma, subgaleal hemorrhage, and retinal hemorrhage due to the suction forces.
NORCET TIP: Retinal hemorrhages post-vacuum are common but generally benign and resolve without affecting vision.

Q47: The vacuum pressure should be raised gradually to create the chignon. What is the standard recommended maximum negative pressure for traction?

Correct Option: C

Rationale: The ideal pressure for traction is 0.6 to 0.8 kg/cm² (500-600 mmHg). Exceeding this limit dramatically increases the risk of scalp avulsion and intracranial bleeding.
NORCET TIP: Pressure is raised in steps (0.2 for application, up to 0.8 for traction during a contraction).

Q48: Between uterine contractions during a vacuum extraction, the obstetrician should:

Correct Option: B

Rationale: Lowering the pressure between contractions minimizes continuous ischemia and trauma to the fetal scalp while maintaining the cup’s position.
NORCET TIP: Traction is *only* applied synchronously with uterine contractions and maternal expulsive efforts.

Q49: Which type of vacuum cup is associated with a lower rate of fetal scalp injury but a higher rate of “pop-offs” (cup detachment)?

Correct Option: B

Rationale: Soft cups mold better to the fetal head, causing fewer scalp lacerations and less severe chignons. However, they cannot generate as rigid a seal as metal cups, leading to higher failure/detachment rates.
NORCET TIP: Metal cups are preferred for occipitoposterior positions where more traction/rotation is needed.

Q50: A nurse is preparing for a vacuum extraction. Which of the following conditions must be met before applying the vacuum cup?

Correct Option: A

Rationale: The vacuum cup must be applied directly to the fetal scalp. If the amniotic sac is intact, the vacuum will pull on the membranes, leading to detachment and failure.
NORCET TIP: As with forceps, the cervix must be fully dilated (10 cm) and the head engaged.

Q51: The phenomenon where the vacuum cup slips and pulls the fetal scalp away from the skull bone is known as:

Correct Option: A

Rationale: Scalp avulsion (tearing or stripping of the scalp) is a severe complication caused by applying too much traction or non-perpendicular traction, especially if the cup is placed incorrectly.
NORCET TIP: Never apply twisting or rotating forces with a vacuum extractor; traction must be in a straight line following the pelvic axis.

Q52: Why is prophylactic administration of Vitamin K to the newborn especially critical after a vacuum extraction delivery?

Correct Option: B

Rationale: Instrumental deliveries (vacuum and forceps) predispose the infant to cephalohematomas and intracranial bleeds. Vitamin K ensures optimal clotting factor synthesis to control any internal bleeding.
NORCET TIP: Observe the newborn for jaundice a few days later, as the breakdown of red blood cells in a cephalohematoma increases bilirubin levels.

Q53: If a vacuum extraction fails (i.e., maximum pop-offs or time limit reached without descent), the standard of care is to:

Correct Option: C

Rationale: Sequential instrumental delivery (failing with a vacuum and then trying forceps) drastically increases the risk of fetal intracranial hemorrhage and maternal trauma. A failed vacuum is an indication for an emergency LSCS.
NORCET TIP: Only very rarely, and by highly experienced operators, might low forceps be used after a failed vacuum if the head is practically on the perineum.

Q54: Which of the following is an absolute indication for a Cesarean section?

Correct Option: B

Rationale: In total placenta previa, the placenta completely covers the internal os. A vaginal delivery is physically impossible and would cause catastrophic maternal and fetal hemorrhage.
NORCET TIP: Other absolute indications include Cephalopelvic Disproportion (CPD), Transverse lie, and Vasa previa.

Q55: The most common type of uterine incision performed in modern obstetrics is the:

Correct Option: B

Rationale: The lower uterine segment transverse incision heals better, bleeds less, and has a much lower risk of uterine rupture in subsequent pregnancies compared to classical incisions.
NORCET TIP: A classical (vertical upper segment) incision is reserved for extreme prematurity, transverse lie, or anterior placenta previa.

Q56: To prevent supine hypotensive syndrome during a cesarean section under spinal anesthesia, the nurse should ensure the patient is positioned with:

Correct Option: B

Rationale: A left lateral tilt of 15 degrees shifts the heavy gravid uterus off the inferior vena cava and aorta (aortocaval compression), maintaining venous return and maternal blood pressure.
NORCET TIP: Spinal anesthesia causes sympathetic blockade and vasodilation, making the mother even more susceptible to hypotension.

Q57: A patient scheduled for an elective LSCS is ordered prophylactic antibiotics. What is the optimal timing for administration?

Correct Option: B

Rationale: Evidence-based guidelines mandate that prophylactic antibiotics (typically a first-generation cephalosporin like Cefazolin) be given within 60 minutes *before* the skin incision to ensure adequate tissue and amniotic fluid levels, reducing surgical site infections.
NORCET TIP: Previously, antibiotics were given after cord clamping to avoid fetal exposure, but this is outdated. Pre-incision is now standard.

Q58: The most common complication of spinal anesthesia used for cesarean sections is:

Correct Option: A

Rationale: Sympathetic blockade from spinal anesthesia causes rapid vasodilation and pooling of blood in the lower extremities, leading to sudden maternal hypotension.
NORCET TIP: Treatment involves left lateral displacement, IV fluid bolus, and vasopressors (Ephedrine or Phenylephrine).

Q59: A patient complains of a severe, throbbing headache 24 hours after a cesarean section under spinal anesthesia. The headache worsens when she sits up and improves when she lies flat. The nurse identifies this as:

Correct Option: B

Rationale: PDPH is caused by cerebrospinal fluid (CSF) leakage from the dural puncture site, causing brain sagging and traction on meninges when upright.
NORCET TIP: Management includes bed rest, hydration, caffeine, analgesics, and if severe/persistent, an epidural blood patch.

Q60: Which patient is the best candidate for a Trial of Labor After Cesarean (TOLAC) / Vaginal Birth After Cesarean (VBAC)?

Correct Option: C

Rationale: One prior low transverse incision is the safest criterion for TOLAC (risk of rupture ~0.5-1%). Classical incisions, T-incisions, and prior ruptures are absolute contraindications due to the high risk of catastrophic uterine rupture.
NORCET TIP: Always review the operative report from the previous surgery to confirm the type of *uterine* (not just skin) incision.

Q61: During a Trial of Labor After Cesarean (TOLAC), the most consistent and earliest sign of impending uterine rupture is:

Correct Option: C

Rationale: Fetal distress (bradycardia, deep variable or late decelerations) is often the very first sign of uterine rupture. “Tearing pain” and “loss of station” are classic signs but often occur later.
NORCET TIP: Continuous electronic fetal monitoring (CEFM) is absolutely mandatory during TOLAC.

Q62: The Enhanced Recovery After Cesarean (ERAC) protocol advocates for which of the following postoperative interventions?

Correct Option: C

Rationale: ERAC focuses on rapid recovery by encouraging early feeding, early removal of catheters, early ambulation, and multimodal opioid-sparing analgesia. This reduces DVT risk, ileus, and hospital stay.
NORCET TIP: Delaying oral intake until bowel sounds return is outdated. Sips of water and a regular diet can be started once the patient is alert.

Q63: A patient is undergoing an emergency cesarean section. The anesthesiologist requests cricoid pressure during the induction of general anesthesia. What is the purpose of this action (Sellick’s maneuver)?

Correct Option: B

Rationale: Pregnant women are at high risk for aspiration due to delayed gastric emptying and increased abdominal pressure. Cricoid pressure occludes the esophagus, preventing aspiration during endotracheal intubation.
NORCET TIP: Sodium citrate (Bicitra) is also given preoperatively to neutralize gastric acid.

Q64: During a cesarean section, the surgeon notices reddish-colored urine in the Foley catheter drainage bag. What intraoperative complication does this most likely indicate?

Correct Option: B

Rationale: The bladder lies directly anterior to the lower uterine segment. If it is inadvertently nicked or injured during the uterine incision or dissection, hematuria will immediately appear in the catheter bag.
NORCET TIP: The bladder flap (vesicouterine peritoneum) is created to reflect the bladder downwards and protect it.

Q65: Postoperatively, a cesarean patient is at a higher risk of deep vein thrombosis (DVT) than a vaginal delivery patient. Which nursing intervention is the highest priority for DVT prophylaxis?

Correct Option: B

Rationale: Early ambulation is the most effective mechanical method to promote venous return and prevent blood stasis in the lower extremities.
NORCET TIP: Never massage a patient’s calves postoperatively, as this can dislodge a formed thrombus and cause a pulmonary embolism.

Q66: The most common skin incision used for a cesarean section is the Pfannenstiel incision. This is best described as a:

Correct Option: B

Rationale: The Pfannenstiel incision is a transverse cut about 2-3 cm above the pubic symphysis. It offers excellent cosmetic results, decreased pain, and lower rates of dehiscence compared to vertical incisions.
NORCET TIP: In extreme emergencies (e.g., massive abruption), a midline vertical skin incision may be used because it provides faster access to the abdomen.

Q67: A woman is pregnant for the first time and presents with a breech baby at 39 weeks. She undergoes an elective LSCS. She asks the nurse, “Will I always need a cesarean for future babies?” The best response is:

Correct Option: B

Rationale: An unrepeated indication (like a breech baby) combined with a low transverse uterine scar makes the patient an excellent candidate for a Vaginal Birth After Cesarean (VBAC) in future pregnancies.
NORCET TIP: The dictum “once a cesarean, always a cesarean” (Cragin’s rule) was coined when classical vertical incisions were standard, but is no longer valid.

Q68: When assessing lochia post-cesarean section, the nurse expects the amount to be:

Correct Option: C

Rationale: During a cesarean, the surgeon manually wipes and clears the uterine cavity of membranes and blood, which typically results in less lochia flow in the early postpartum period compared to a vaginal delivery.
NORCET TIP: However, heavy bleeding or a sudden increase in bright red lochia must still be evaluated for postpartum hemorrhage.

Q69: How should the nurse assess the uterine fundus in a post-cesarean patient to avoid causing severe pain or surgical wound disruption?

Correct Option: C

Rationale: Supporting the lower segment stabilizes the uterus and prevents traction on the fresh surgical incision, minimizing pain while allowing essential assessment of uterine tone (firmness).
NORCET TIP: A boggy uterus post-cesarean is just as dangerous as post-vaginal delivery and indicates uterine atony.

Q70: Babies born via elective cesarean section without a preceding trial of labor are at increased risk for which neonatal respiratory complication?

Correct Option: B

Rationale: During a vaginal delivery, the mechanical squeeze of the birth canal and stress hormones (catecholamines) help clear lung fluid. In an elective cesarean, this fluid is retained, causing TTN (“wet lung”).
NORCET TIP: TTN presents with rapid breathing shortly after birth but is usually benign and resolves with supportive oxygen therapy in 24-48 hours.

Q71: A woman with placenta previa totalis and a history of three prior cesarean sections is highly suspected of having Placenta Accreta. The surgical team prepares for a cesarean section. What other major surgical procedure should the team be prepared for?

Correct Option: C

Rationale: Placenta accreta (morbidly adherent placenta) cannot separate from the uterine wall. Forcible removal causes massive hemorrhage. The standard definitive treatment is to deliver the baby via cesarean and immediately perform a hysterectomy with the placenta left in situ.
NORCET TIP: The combination of placenta previa and prior cesarean sections is the biggest risk factor for placenta accreta.

Q72: Which medication is most appropriate for a post-cesarean patient complaining of severe abdominal cramping caused by trapped intestinal gas?

Correct Option: B

Rationale: Simethicone reduces the surface tension of gas bubbles, allowing them to be expelled. Opioids (like Morphine) worsen gas pain by slowing bowel motility.
NORCET TIP: Early ambulation and avoiding carbonated beverages are the best non-pharmacological interventions for post-op gas pain.

Q73: The primary reason for administering a non-particulate antacid (e.g., Sodium Citrate) immediately before an emergency cesarean under general anesthesia is to:

Correct Option: B

Rationale: Aspiration of highly acidic gastric contents (pH <2.5) causes severe chemical pneumonitis (Mendelson’s syndrome). Sodium citrate raises the gastric pH, making the aspirate less damaging to the lungs.
NORCET TIP: Metoclopramide is often given alongside it to increase the lower esophageal sphincter tone and promote gastric emptying.

Q74: What is the optimal gestational age to attempt an External Cephalic Version (ECV) for a singleton breech presentation?

Correct Option: B

Rationale: ECV is performed at 37 weeks (term). If done earlier, the fetus may spontaneously turn back, or if a complication forces an emergency delivery, the baby would be premature. At 37 weeks, the baby is mature but still has enough amniotic fluid to turn.
NORCET TIP: Do not perform ECV prior to 36-37 weeks unless as part of a specific trial protocol.

Q75: Which of the following is an absolute contraindication to performing an External Cephalic Version (ECV)?

Correct Option: B

Rationale: Any condition that precludes a vaginal delivery (like placenta previa, severe cephalopelvic disproportion, or active herpes) is an absolute contraindication for ECV. Manipulating a placenta previa would cause massive hemorrhage.
NORCET TIP: Previous cesarean section is generally a relative contraindication, but many guidelines now consider it acceptable with careful counseling.

Q76: A patient is scheduled for an ECV. To relax the uterus and increase the chances of a successful version, which medication is commonly administered beforehand?

Correct Option: B

Rationale: Terbutaline is a beta-2 adrenergic agonist used as a tocolytic to relax the uterine musculature, making it easier to manually manipulate the fetus through the maternal abdomen.
NORCET TIP: Monitor maternal heart rate, as terbutaline causes significant maternal tachycardia.

Q77: An Rh-negative pregnant woman undergoes a successful External Cephalic Version. What is the priority pharmacological nursing intervention post-procedure?

Correct Option: B

Rationale: ECV involves forceful manipulation of the uterus, carrying a risk of fetomaternal hemorrhage. If the mother is Rh-negative, Anti-D immunoglobulin must be given within 72 hours to prevent Rh isoimmunization.
NORCET TIP: A Kleihauer-Betke test may be drawn to quantify the fetal-maternal bleed and adjust the RhoGAM dose if necessary.

Q78: What essential assessment must be performed continuously before, immediately after, and occasionally during an ECV?

Correct Option: B

Rationale: Fetal distress (bradycardia, decelerations) due to umbilical cord compression or placental abruption is a major risk of ECV. A reactive NST is required before the procedure, and post-procedure monitoring is mandatory.
NORCET TIP: If severe fetal bradycardia occurs during the turn, the procedure is immediately abandoned and the fetus is pushed back to the original position.

Q79: Which ultrasound finding would make a physician cancel a planned ECV?

Correct Option: B

Rationale: Adequate amniotic fluid is required to allow the fetus to glide and turn inside the uterus. Oligohydramnios increases friction, increases the risk of cord compression, and drastically lowers the success rate.
NORCET TIP: Polyhydramnios makes ECV very easy, but the baby often flips back to breech soon after.

Q80: A woman undergoing an ECV suddenly complains of severe, sharp, continuous abdominal pain, and her abdomen becomes board-like and rigid. The fetal monitor shows severe bradycardia. The nurse suspects:

Correct Option: C

Rationale: The shearing forces of an ECV can prematurely detach the placenta. Classic signs are sudden severe pain, rigid abdomen, vaginal bleeding (not always visible), and fetal distress.
NORCET TIP: This is an extreme emergency requiring immediate cesarean delivery.

Q81: Because of the risk of emergency complications during an ECV, what is a mandatory prerequisite for the setting in which the procedure is performed?

Correct Option: B

Rationale: Due to the risk of cord entanglement, placental abruption, and fetal bradycardia, ECV must only be performed where an emergency LSCS can be done immediately.
NORCET TIP: The patient must sign a consent form for both the ECV and a possible emergency cesarean section.

Q82: The technique of External Cephalic Version involves:

Correct Option: C

Rationale: The obstetrician uses ultrasound guidance and external palpation to “disimpact” the breech and encourage the fetus to perform a “forward roll” or “backward flip.”
NORCET TIP: “Internal podalic version” is a completely different procedure, mainly used historically to deliver a retained second twin.

Q83: Which of the following factors is a predictor of a highly SUCCESSFUL external cephalic version?

Correct Option: B

Rationale: Multiparous women have laxer abdominal and uterine muscles, making it much easier to manipulate the fetus compared to the tight muscles of a primigravida.
NORCET TIP: Adequate amniotic fluid and a non-engaged presenting part are also predictors of success.

Q84: After a successful ECV, the nurse’s discharge instructions should include telling the mother to return to the hospital immediately if she experiences:

Correct Option: B

Rationale: These are signs of placental abruption, premature rupture of membranes (PROM), or fetal distress. Mild abdominal soreness is expected from the external pressure.
NORCET TIP: The patient is usually observed for 1-2 hours on the fetal monitor before being discharged.

Q85: True or False: ECV guarantees a vaginal delivery.

Correct Option: B

Rationale: ECV reduces the *chance* of needing a breech cesarean, but up to 5% of babies will spontaneously revert to breech, and typical labor complications (CPD, fetal distress) can still mandate an LSCS.
NORCET TIP: An engaged breech presentation cannot be turned.

Q86: How long after the delivery of the baby is a placenta generally considered “retained” if it has not delivered despite active management of the third stage of labor?

Correct Option: B

Rationale: A placenta that has not been expelled within 30 minutes of the infant’s birth is diagnosed as a retained placenta, and manual removal is indicated to prevent severe postpartum hemorrhage.
NORCET TIP: Active management (oxytocin, controlled cord traction) normally delivers the placenta within 5-15 minutes.

Q87: Before attempting a manual removal of the placenta, what is the absolute priority nursing action?

Correct Option: B

Rationale: Manual removal is associated with profuse, life-threatening hemorrhage. Establishing 2 large-bore IVs and having blood ready is the top priority for maternal safety.
NORCET TIP: Always anticipate postpartum hemorrhage (PPH) with any retained placenta.

Q88: Which condition makes manual removal of the placenta impossible and highly dangerous due to the placenta invading the myometrium?

Correct Option: B

Rationale: In placenta accreta, the chorionic villi attach directly to the myometrium (missing the decidua basalis). There is no plane of cleavage. Forcible removal will cause catastrophic bleeding.
NORCET TIP: If the obstetrician cannot find a cleavage plane during manual removal, accreta is suspected, the procedure is stopped, and emergency hysterectomy is prepared.

Q89: What type of anesthesia is typically required for a manual removal of the placenta?

Correct Option: C

Rationale: The procedure requires introducing the whole hand into the uterine cavity, which is extremely painful and requires total uterine relaxation. Spinal/epidural or general anesthesia is mandatory.
NORCET TIP: Nitrous oxide or IV opioids are insufficient for this invasive procedure.

Q90: During manual removal of the placenta, why is it critical for the provider to place their other hand externally on the maternal abdomen to grasp the uterine fundus?

Correct Option: B

Rationale: Counter-traction provided by the external hand supports the fundus, preventing the severe and often fatal complication of uterine inversion while the internal hand strips the placenta.
NORCET TIP: Uterine inversion presents as profound shock out of proportion to blood loss, and a mass protruding from the vagina.

Q91: Which part of the hand is used to separate the placenta from the uterine wall during manual removal?

Correct Option: B

Rationale: The ulnar edge of the hand is used in a gentle, side-to-side sweeping or slicing motion to find and expand the cleavage plane between the placenta and the uterine wall.
NORCET TIP: Using fingertips or a clawing motion increases the risk of uterine perforation.

Q92: What medication is routinely administered *immediately after* the placenta is manually removed?

Correct Option: B

Rationale: Once the uterus is empty, profound atony is common. High-dose IV oxytocin (and sometimes Methergine or Carboprost) is given immediately to contract the uterus and stop bleeding.
NORCET TIP: Do not give Methergine to a patient with hypertension or preeclampsia.

Q93: Retained placenta is broadly classified into three causes. Which of the following is NOT a cause?

Correct Option: D

Rationale: Previa relates to placental location, not retention. Retained placenta is caused by failure of separation, trapped placenta (a contraction ring forms at the cervix), or morbid adherence (accreta).
NORCET TIP: A trapped placenta can sometimes be delivered simply by relaxing the uterus with nitroglycerin or anesthesia, avoiding full manual removal.

Q94: A patient has a manual removal of the placenta. 7 days postpartum, she presents with fever, foul-smelling lochia, and uterine tenderness. She is most likely experiencing:

Correct Option: B

Rationale: Introducing a hand into the sterile uterine cavity greatly increases the risk of introducing vaginal flora, leading to endometritis (infection of the uterine lining).
NORCET TIP: Prophylactic broad-spectrum antibiotics (like Ampicillin and Metronidazole) are routinely given immediately after manual removal to prevent this.

Q95: When examining a manually removed placenta, the nurse notes that a cotyledon is missing. The most appropriate immediate action is to:

Correct Option: B

Rationale: A missing cotyledon indicates retained placental fragments inside the uterus, which will cause secondary postpartum hemorrhage and severe infection. The cavity must be explored (manually or via curettage).
NORCET TIP: Always inspect the maternal surface of the placenta to ensure all cotyledons are intact and fit together like a puzzle.

Q96: The Brandt-Andrews maneuver is related to placental delivery. What does it entail?

Correct Option: B

Rationale: This maneuver involves pulling the cord gently while pushing the uterus upward and backward to prevent uterine inversion during active management of the third stage.
NORCET TIP: If the placenta does not separate with this maneuver within 30 minutes, manual removal is indicated.

Q97: A placenta percreta differs from placenta accreta because in percreta:

Correct Option: B

Rationale: Accreta spectrum: Accreta (attaches to myometrium), Increta (invades deep into myometrium), Percreta (invades through the uterus into surrounding structures).
NORCET TIP: Hematuria during pregnancy in a patient with placenta previa strongly suggests placenta percreta invading the bladder.

Q98: A severe complication of uncontrolled pulling on the umbilical cord to deliver a retained placenta is:

Correct Option: A

Rationale: Forceful pulling without counter-traction can snap the cord (avulsion) making subsequent delivery harder, or worse, pull the fundus inside out (inversion).
NORCET TIP: Never pull forcefully on an umbilical cord.

Q99: After a manual removal of the placenta, the nurse palpates the fundus and finds it boggy and displaced to the right. What is the priority nursing action?

Correct Option: B

Rationale: A full bladder displaces the uterus (usually to the right) and prevents it from contracting, leading to atony and hemorrhage. Emptying the bladder allows the uterus to contract down to the midline.
NORCET TIP: Always check the bladder status when dealing with a boggy uterus.

Q100: During the manual removal procedure, aseptic technique is paramount. The obstetrician should wear:

Correct Option: B

Rationale: Because the provider’s hand and forearm must enter the vagina and uterine cavity, elbow-length (gauntlet) sterile gloves are required to maintain asepsis and protect both patient and provider.
NORCET TIP: Good infection control prevents puerperal sepsis, a leading cause of maternal mortality.
