1. Important Terms to Know

• Addiction: When a person cannot stop using a drug even though it is ruining their life or health.
• Tolerance: The body gets used to the drug, so the person needs to take more of it to get the same “high.”
• Withdrawal: The physical and mental sickness that happens when a person suddenly stops taking a drug they are used to.
• Dependence: The body relies on the drug just to feel normal.
• Dual Diagnosis: When a patient has both a drug problem and a mental health problem (like having alcohol addiction and depression).
• Denial: The most common defense mechanism. The patient refuses to admit they have a drug problem.

2. Alcohol Dependence

Alcohol slows down the brain (it is a depressant). Long-term drinking damages the brain and liver.

Important Complications

• Wernicke’s Encephalopathy: Brain damage caused by low Vitamin B1 (Thiamine).
  • Signs: Confusion, wobbly walking (ataxia), and eye movement problems. It can be fixed if treated early.
• Korsakoff’s Syndrome: Permanent memory loss from low Vitamin B1.
  • Signs: The patient makes up fake stories to fill in the blank spots in their memory (this is called confabulation).
• Cirrhosis: The liver becomes scarred and stops working.

Alcohol Withdrawal Timeline (High-Yield for Exams) Withdrawal can be deadly. Keep a close watch on the clock.

Time Since Last Drink	What Happens	Nursing Action
6 to 12 Hours	Mild signs: Shaking hands (tremors), sweating, fast heartbeat, anxiety.	Use the CIWA scale to score symptoms. Give Benzodiazepines (like Lorazepam).
12 to 24 Hours	Hallucinations: Seeing bugs or animals that are not there, but the patient still knows who and where they are.	Keep the room quiet and safe. Reassure the patient.
24 to 48 Hours	Seizures: Full-body shaking and loss of consciousness.	Pad the bed rails. Keep the airway open.
48 to 72 Hours	Delirium Tremens (DTs): Medical Emergency! Very high fever, extreme confusion, racing heart. Can be fatal.	Move to ICU. Give IV fluids and high doses of IV Benzodiazepines.

3. Opioid Misuse

Opioids are strong painkillers. Examples include Heroin, Morphine, Fentanyl, and Oxycodone.

Opioid Overdose (Emergency)

• The Overdose Triad (Classic 3 Signs): Pinpoint pupils (tiny black circles in the eyes), very slow breathing, and being unconscious.
• Antidote: Naloxone (Narcan). It wakes the patient up quickly but wears off fast, so you might need to give it more than once.

Opioid Withdrawal

• Unlike alcohol, opioid withdrawal will not kill you, but it feels like the worst flu ever.
• Signs: Yawning, runny nose, goosebumps, muscle cramps, sweating, big (dilated) pupils, and diarrhea.
• Scale used: COWS (Clinical Opiate Withdrawal Scale).

4. Cannabis (Marijuana) Use

The main active chemical is THC.

• Intoxication Signs: Red bloodshot eyes, extreme hunger (the “munchies”), dry mouth, and slow reaction times.
• Amotivational Syndrome: If used heavily for a long time, the person completely loses their drive, goals, and stops caring about their life or grooming.
• Hyperemesis Syndrome: A weird reaction in long-term users where they throw up constantly. The only thing that stops the vomiting is taking a very hot shower or bath.

5. Tobacco / Nicotine Use

Nicotine is a stimulant that is highly addictive.

• Withdrawal Signs: Feeling angry, anxious, strong cravings, and eating more (weight gain).
• Medicines Used to Help Quit:
  • Nicotine Patches: Give a steady dose of nicotine to stop cravings. (Exam tip: Always remove the patch before an MRI scan to prevent skin burns).
  • Bupropion (Zyban): A pill that stops cravings. Do not give to patients with a history of seizures.
  • Varenicline (Chantix): Works very well, but nurses must watch the patient closely for bad dreams, depression, or suicidal thoughts.

6. General Withdrawal Management (Detox)

The goal is to help the patient stop using drugs safely.

Important Screening Tools

• CAGE Questionnaire: 4 simple questions for alcohol abuse. If they answer “Yes” to 2 or more, they likely have a drinking problem.
  1. Have you ever felt you should Cut down?
  2. Are people Annoyed by your drinking?
  3. Do you feel Guilty about drinking?
  4. Do you need an Eye-opener (a drink in the morning)?

Medicines to Keep Patients Sober

Medicine	Used For	Important Nursing Tips
Disulfiram (Antabuse)	Alcohol	Makes the patient violently sick if they drink alcohol. Teach them to avoid ALL hidden alcohol (mouthwash, vanilla extract, hand sanitizer).
Naltrexone	Alcohol & Opioids	Takes away the “high” feeling and cuts cravings.
Methadone	Opioids	A safe daily pill given in a clinic to replace heroin and stop cravings.

7. Therapies for Rehabilitation

Rehab helps the patient learn how to live without the drug.

• Cognitive Behavioral Therapy (CBT): Helps the patient figure out what triggers them to use drugs and teaches them new, healthy ways to handle stress.
• Group Therapy: Very important because it shows the patient they are not alone. Peers in the group can help break the patient’s “denial.”
• Alcoholics Anonymous (AA) / 12-Step Programs: Support groups run by other people in recovery. The goal is total sobriety (no drinking at all) and admitting they are powerless over the addiction.

8. Nursing Management & Care Plan

Top Priority Nursing Diagnoses

1. Risk for Injury (Top priority due to seizures and confusion during withdrawal).
2. Ineffective Denial (The patient says, “I don’t have a problem, I can quit whenever I want”).
3. Imbalanced Nutrition (Patients often drink or do drugs instead of eating).

Nursing Interventions (What the Nurse Must Do) 

• Keep them safe: Put padded rails on the bed for seizure risks. Keep the room quiet and calm.
• Nutrition Rule (Very Important): For alcoholics, ALWAYS give Vitamin B1 (Thiamine) before giving any sugary IV fluids (like Dextrose). If you give sugar before Thiamine, it can trigger Wernicke’s Encephalopathy (brain damage).
• How to talk to the patient: Be kind but firm. Do not judge them. Do not argue with them. State the facts clearly (e.g., “Your lab tests show your liver is failing because of the alcohol”).
• Set rules: Patients with addiction might try to manipulate the staff. Set clear, strict rules and make sure all nurses follow them exactly the same way.
