Key Components of an Effective NCLEX Pharmacology Cheat Sheet
An effective cheat sheet should encompass essential categories of drugs and concepts, including:
1. Drug Classifications and Examples
2. Mechanisms of Action
3. Common Side Effects and Adverse Reactions
4. Nursing Considerations and Patient Teaching
5. Special Notes for High-Risk Medications
Let's delve into each section in detail.

1. Drug Classifications and Examples
Understanding drug classes and their representative medications is fundamental. Here are some key categories frequently tested on the NCLEX:
a. Analgesics
- Opioids: Morphine, Hydromorphone, Fentanyl
- NSAIDs: Ibuprofen, Naproxen
- Acetaminophen: Acetaminophen (Tylenol)
b. Antibiotics
- Penicillins: Amoxicillin, Penicillin G
- Cephalosporins: Ceftriaxone, Cephalexin
- Macrolides: Azithromycin, Erythromycin
- Fluoroquinolones: Ciprofloxacin, Levofloxacin
c. Antihypertensives
- ACE inhibitors: Lisinopril, Enalapril
- Beta-blockers: Metoprolol, Propranolol
- Diuretics: Furosemide, Hydrochlorothiazide
- Calcium Channel Blockers: Amlodipine, Diltiazem
d. Cardiovascular Agents
- Anticoagulants: Warfarin, Heparin
- Nitrates: Nitroglycerin
- Lipid-lowering agents: Atorvastatin, Simvastatin
e. Respiratory Drugs
- Beta-agonists: Albuterol, Salmeterol
- Inhaled Corticosteroids: Fluticasone, Budesonide
f. Psychiatric Medications
- SSRIs: Fluoxetine, Sertraline
- Antipsychotics: Risperidone, Olanzapine
- Mood Stabilizers: Lithium
g. Endocrine Medications
- Insulins: Regular, NPH, Glargine
- Oral hypoglycemics: Metformin, Glipizide
---
2. Mechanisms of Action
Knowing how drugs work helps in understanding their effects and anticipating side effects:
- ACE inhibitors: Block conversion of angiotensin I to angiotensin II, resulting in vasodilation.
- Beta-blockers: Block beta-adrenergic receptors, decreasing heart rate and blood pressure.
- NSAIDs: Inhibit cyclooxygenase (COX), reducing prostaglandin synthesis, alleviating pain and inflammation.
- Opioids: Bind to opioid receptors in the CNS, altering perception of pain.
- Diuretics: Promote excretion of sodium and water to decrease blood volume and pressure.
- Insulins: Mimic endogenous insulin to facilitate glucose uptake.

3. Common Side Effects and Adverse Reactions
Quick identification of side effects is vital for safe administration:
a. Opioids
- Side Effects: Constipation, sedation, respiratory depression
- Nursing Alerts: Monitor respiratory rate; avoid alcohol
b. ACE Inhibitors
- Side Effects: Dry cough, hyperkalemia, hypotension
- Nursing Alerts: Monitor BP and serum potassium
c. NSAIDs
- Side Effects: Gastric irritation, bleeding, renal impairment
- Nursing Alerts: Assess for signs of bleeding; give with food
d. Diuretics
- Side Effects: Dehydration, electrolyte imbalances (hypokalemia or hyperkalemia)
- Nursing Alerts: Monitor electrolyte levels and hydration status
e. Insulin
- Side Effects: Hypoglycemia, weight gain
- Nursing Alerts: Educate on blood glucose monitoring and hypoglycemia management
f. Antibiotics
- Side Effects: Allergic reactions, gastrointestinal upset
- Nursing Alerts: Assess for allergy history; monitor bowel movements
---
4. Nursing Considerations and Patient Teaching
Proper medication administration and patient education are crucial to ensure safety:
- Always verify medication orders and patient allergies.
- Administer drugs at the correct time and dosage.
- Monitor for therapeutic effects and adverse reactions.
- Educate patients on medication purpose, potential side effects, and adherence.
- Advise on lifestyle modifications that complement medication therapy.
- Instruct on the importance of blood tests (e.g., INR for warfarin).
---
5. Special Notes for High-Risk Medications
Certain drugs require extra caution:
a. Warfarin
- Monitor INR regularly
- Avoid foods high in vitamin K
- Watch for signs of bleeding
b. Lithium
- Monitor serum levels routinely
- Maintain consistent salt and fluid intake
- Watch for signs of toxicity (tremors, nausea)
c. Insulin
- Always check blood glucose before administration
- Know how to handle hypoglycemia (glucose tablets, glucagon)

Additional Tips for NCLEX Pharmacology Success
- Create Mnemonics: Develop memory aids for drug classes and side effects.
- Use Flashcards: Regularly review drug names, classifications, and nursing interventions.
- Practice Case Studies: Apply pharmacology knowledge in clinical scenarios.
- Stay Updated: Keep current with new medications and guidelines.
