NUR2474 PHARMACOLOGY EXAM 1
COMPREHENSIVE REVIEW (LATEST
2026/ 2027 UPDATE) QUESTIONS AND
100% CORRECT VERIFIED ANSWERS|
GRADE A+
1. A nurse is administering a drug that has a narrow therapeutic index. Which action is most
important for the nurse to take?
A. Monitor the patient for signs of toxicity and check blood levels.
B. Administer the medication as quickly as possible.
C. Inform the patient that side effects are unlikely.
D. Teach the patient to double the dose if a dose is missed.
Answer: A
Conceptual Explanation: Drugs with a narrow therapeutic index have a small margin of
safety between a therapeutic dose and a toxic dose, requiring close monitoring of serum
drug levels.
,2. A patient is prescribed an oral medication that undergoes a significant first-pass effect.
How does this affect the medication’s bioavailability?
A. It decreases the amount of active drug reaching the systemic circulation.
B. It has no impact on the drug’s effectiveness.
C. It increases the amount of active drug in the systemic circulation.
D. It speeds up the rate of absorption in the small intestine.
Answer: A
Conceptual Explanation: The first-pass effect occurs when a drug is metabolized by the
liver before reaching systemic circulation, significantly reducing its bioavailability.
3. Which pharmacokinetic phase is most affected by a patient having severe chronic kidney
disease?
A. Excretion
B. Distribution
C. Metabolism
D. Absorption
Answer: A
Conceptual Explanation: The kidneys are the primary organs for drug excretion. Impaired
renal function leads to decreased excretion and potential drug accumulation.
, 4. A patient with liver cirrhosis may have difficulty with which aspect of pharmacokinetics?
A. Absorption
B. Excretion
C. Metabolism
D. Ingestion
Answer: C
Conceptual Explanation: The liver is the primary site for drug metabolism. Cirrhosis
impairs the liver’s ability to break down drugs, increasing the risk of toxicity.
5. What is the primary purpose of a ‘loading dose’?
A. To reduce the risk of allergic reactions.
B. To bypass the kidneys entirely.
C. To reach a therapeutic steady state more quickly.
D. To prevent the first-pass effect.
Answer: C
Conceptual Explanation: A loading dose is a large initial dose given to rapidly achieve a
therapeutic drug level (steady state) in the blood.
6. A drug that binds to a receptor and prevents a response is known as a(n):
A. Antagonist
