NCLEX exam is fast approaching and you don’t know NCLEX-style pharmacology questions? Worry no more as we have prepared this NCLEX pharmacology cheat sheet specifically for you.
Use this guide and utilize the rest of the resources we offer here at Naxlex and be guaranteed a score above 90.
Students studying nursing pharmacology must understand the use and function of medication. An easy way to memorize medication is to familiarize yourself with the generic name stem. Note that drugs of the same therapeutic class have names with similar stems. The stems are usually placed word-finally(suffix) and also in some cases word-initial(prefix)

NClEX Pharmacology Questions
The NCLEX exam will test your pharmacology knowledge in the following areas.
General Pharmacology
These questions test foundational knowledge about medications. These include:
- Routes of administration (oral, intravenous, etc.)
- Pharmacodynamics (how drugs interact with the body to produce effects)
- Pharmacokinetics (how the body absorbs, distributes, metabolizes, and excretes drugs)
- Medication terminology (generic vs. brand names, dosage forms, etc.)
- Legal and ethical considerations of medication use
Drug Classes
You’ll tackle Pharmacology questions that look into specific categories of medications based on their therapeutic effects or chemical structure. Examples include:
- Antibiotics
- Analgesics (pain relievers)
- Antihypertensives (blood pressure medications)
- Cardiovascular medications
- Antidiabetics
- Corticosteroids
Mechanisms of Action
As a nurse, you must understand how medications work at a cellular or molecular level. Questions might ask how a drug binds to a receptor, alters a metabolic pathway, or produces a specific physiological response.
Since you now understand what to expect in the NCLEX exam, try our pharmacology quizzes below. These quizzes are the best way to test your knowledge of medicines and identify your strengths and weaknesses. Use them to help you plan your future study plans.
Pharmacology Quizzes
Note: We’ve bolded the correct answer among the choices in each question.
-
1. A patient with chronic obstructive pulmonary disease (COPD) is taking albuterol. Which of the following mechanisms of action best describes how albuterol works?
- A. Binds to beta-adrenergic receptors, causing bronchoconstriction (Incorrect Answer)
- B. Binds to beta-adrenergic receptors, causing bronchodilation
- C. Inhibits angiotensin-converting enzyme (ACE) to lower blood pressure
-
2. A nurse is reviewing a medication order for a patient with a potassium deficiency. Which of the following medications is MOST appropriate for replacement therapy?
- Furosemide (Lasix) - Diuretic
- Lisinopril (Zestril) - ACE Inhibitor
- Potassium Chloride (KCl)
- Metformin (Glucophage) - Antidiabetic
-
3. A patient is prescribed heparin to prevent blood clots. The nurse understands this medication works through which mechanism of action?
- Inhibits platelet aggregation
- Dissolves existing blood clots
- Increases blood pressure by constricting blood vessels
- Lowers blood sugar levels by increasing insulin production
-
4. A client with type 2 diabetes mellitus is taking metformin. The nurse teaches the client about potential side effects. Which of the following statements is MOST accurate regarding metformin and food intake?
- Metformin should be taken on an empty stomach for best absorption.
- Metformin can be taken with food to minimize gastrointestinal upset.
- Metformin should be avoided if the client consumes any alcohol.
-
Prednisolone increases the risk of tendon rupture when taken with fluoroquinolones like ciprofloxacin.
- True
- False
-

- Increased risk of drowsiness
- Increased risk of gastrointestinal bleeding
- Decreased effectiveness of ibuprofen for pain relief
-
8. The following are side effects of suxamethonium, except which?
- Hyperkalemia
- Myopathies

- Difficulty breathing
- Headache
- Nausea and vomiting
- Difficulty sleeping
Tips To Help You Answer Pharmacology MCQS
Re-read Each Question Before Answering
Before answering any question, it's always important to double-check and avoid missing important words. Check for words such as “always” or “not” as they can completely transform the meaning of a multiple-choice question.
Use Choice Elimination
To reduce the risk of errors in your NCLEX exam, it's important to eliminate the wrong answers first. Review each choice carefully, and eliminate the wrong ones—this improves the chances of choosing the correct answer.
