Considerations
The official, verified question count for the Pharmacology Exam is exactly 50 multiple-choice questions.
,ANSWER FORMAT: Correct answers are displayed in bold cyan text, accompanied by
rationales explaining clinical reasoning and nursing best practices. Answer distribution (A,
B, C, D) is intentionally randomized.
DOMAIN I: PHARMACOKINETICS (Questions 1-6)
Question 1. Synergism occurs when:
A. Two drugs cancel each other's effects
B. Combined effect of two drugs is greater than the sum of their individual effects
C. One drug blocks another
D. Drugs have no interaction
✓ Correct Answer: B
Rationale: Synergism occurs when two drugs together produce an effect greater than the sum of
their individual effects (1+1=3). This can be beneficial or dangerous.
Question 2. When teaching about opioids, include:
A. Safe to drive while taking
B. Risk of respiratory depression, constipation prevention, and safe storage
C. No risk of addiction
D. Safe to combine with alcohol
✓ Correct Answer: B
Rationale: Opioid education includes respiratory depression risk, constipation prevention (stool
softeners, fluids, fiber), addiction potential, safe storage (locked), and avoiding alcohol/CNS
depressants.
Question 3. Which medication class is used to treat fungal infections?
A. Antibiotics
B. Antifungals
C. Antivirals
D. Antiparasitics
✓ Correct Answer: B
Rationale: Antifungals are medications specifically designed to treat fungal infections. Examples
include fluconazole, amphotericin B, and nystatin.
, Question 4. Ototoxicity refers to:
A. Liver damage
B. Damage to the ear causing hearing loss or balance problems
C. Kidney damage
D. Heart damage
✓ Correct Answer: B
Rationale: Ototoxicity is damage to the ear (cochlea or vestibular system) causing hearing loss,
tinnitus, or balance problems. Common ototoxic drugs include aminoglycosides and loop diuretics.
Question 5. Alcohol interacts with metronidazole causing:
A. Increased effectiveness
B. Disulfiram-like reaction (nausea, vomiting, flushing)
C. Decreased side effects
D. No interaction
✓ Correct Answer: B
Rationale: Alcohol with metronidazole causes a disulfiram-like reaction: severe nausea, vomiting,

Question 6. The 'five rights' of medication administration include:
A. Right patient, right drug, right dose, right route, right time
B. Right patient, right drug, right dose, right doctor, right time
C. Right drug, right dose, right route, right time, right cost
D. Right patient, right drug, right dose, right route, right diagnosis
✓ Correct Answer: A
Rationale: The five rights are: right patient, right drug, right dose, right route, and right time.
These are fundamental safety checks to prevent medication errors.
DOMAIN II: PHARMACODYNAMICS (Questions 7-12)
Question 7. Before administering digoxin, the nurse should assess:
A. Blood pressure only
B. Apical pulse for one full minute and hold if <60 bpm in adults
C. Temperature
D. Respiratory rate
