Core Domains:
Pharmacokinetics (Absorption, Distribution, Metabolism, Excretion)
Pharmacodynamics (Receptor theory, dose-response, agonists/antagonists)
Medication safety and error prevention (High-alert meds, rights of administration)
Drug classifications and prototype drugs
Regulatory and legal frameworks (FDA schedules, DEA, controlled substances)
Nursing process applied to pharmacology (Assessment, diagnosis, planning, intervention, evaluation)
Adverse effects, toxicity, and drug interactions
Patient education and cultural considerations
Lifespan pharmacology (Pediatric, pregnancy/lactation, geriatric)
Ethical and professional standards in medication management
Introduction
This examination is designed to assess foundational and applied knowledge in pharmacology for nursing
,practice. It evaluates comprehension of pharmacokinetic and pharmacodynamic principles, drug classifications,
medication safety protocols, legal and ethical responsibilities, and clinical decision-making in medication
administration. Questions include direct recall, application-based scenarios, and prioritization using the nursing
process. Emphasis is placed on real-world nursing judgment, adverse effect recognition, patient teaching, and
regulatory compliance. Each multiple-choice item is followed by a verified correct answer and a concise
rationale to reinforce learning. This tool prepares students for course examinations and clinical readiness.
SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is preparing to administer a medication that is known to be highly protein-bound. Which statement
correctly reflects the clinical significance of this property?
A. The drug will be excreted rapidly by the kidneys.
B. A second highly protein-bound drug may displace the first, increasing free drug levels.
C. Oral absorption will be nearly 100% regardless of food intake.
D. The drug will have a very narrow therapeutic index.
🟢B
🔴 RATIONALE: Protein binding is reversible; when two highly protein-bound drugs compete for binding sites,
displacement increases free (active) drug concentration, raising risk of toxicity.
,Question 2
A client receives a new prescription for a drug that is a weak acid. The nurse expects that absorption will be
fastest in which part of the gastrointestinal tract?
A. Colon
B. Stomach
C. Small intestine
D. Mouth (buccal mucosa)
🟢B
🔴 RATIONALE: Weak acids are non-ionized and lipid-soluble in acidic environments (stomach, pH ~1.5–3.5),
favoring passive absorption. Weak bases are better absorbed in the small intestine.
Question 3
A patient with heart failure is prescribed digoxin. The nurse notes the patient also takes hydrochlorothiazide.
Which laboratory value requires the most immediate intervention due to the risk of digoxin toxicity?
A. Serum sodium 135 mEq/L
B. Serum potassium 2.9 mEq/L
C. Serum calcium 9.2 mg/dL
D. Serum magnesium 2.0 mg/dL
🟢B
, 🔴 RATIONALE: Hypokalemia increases the risk of digoxin toxicity by enhancing binding to myocardial sodium-
potassium ATPase. Thiazide diuretics can cause hypokalemia.
Question 4
A nurse is reviewing a patient’s medication list and identifies a drug that acts as a competitive antagonist at
beta-1 adrenergic receptors. Which effect is expected?
A. Increased heart rate and contractility
B. Decreased heart rate and reduced myocardial oxygen demand
C. Bronchodilation and increased respiratory rate
D. Vasodilation and decreased peripheral resistance
🟢B
🔴 RATIONALE: Beta-1 blockade in the heart reduces heart rate, conduction velocity, and contractility, lowering
oxygen demand. This is the therapeutic mechanism of beta-blockers like metoprolol.
Question 5
A nurse administers furosemide intravenously to a patient with pulmonary edema. Which pharmacokinetic
phase determines the onset of action for this IV dose?
A. Absorption
B. Distribution
