ADVANCED PHARMACOLOGY QUIZ
(NURS 180) 2026 QUESTIONS AND
ANSWERS
1. A patient with chronic kidney disease is prescribed a drug that is primarily eliminated by
the kidneys. What pharmacokinetic change should the nurse anticipate?
A. Increased rate of drug metabolism
B. Increased risk of drug toxicity
C. Decreased drug half-life
D. Increased drug volume of distribution
Answer: B
Conceptual Explanation: Decreased renal function reduces the clearance of drugs, leading
to accumulation in the bloodstream and an increased risk of toxicity.
2. Which of the following describes a drug that acts as a partial agonist?
A. It binds to a receptor and prevents any biological response.
B. It binds to a receptor and produces a maximal response.
C. It binds to a receptor to increase the affinity of other ligands.
D. It binds to a receptor but produces a lower maximal effect than a full agonist.
,Answer: D
Conceptual Explanation: A partial agonist has lower intrinsic activity compared to a full
agonist, even when all receptors are occupied.
3. A patient is receiving an intravenous infusion of a drug with a half-life of 4 hours. How long
will it take for the drug to reach steady state?
A. 4 hours
B. 8 to 12 hours
C. 32 to 40 hours
D. 16 to 20 hours
Answer: D
Conceptual Explanation: Steady state is generally reached after 4 to 5 half-lives (4 hours x
4 or 5 = 16 to 20 hours).
4. The nurse is monitoring a patient taking Gentamicin. Which laboratory values are most
important to assess to prevent adverse effects?
A. Serum sodium and potassium
B. Aspartate aminotransferase (AST) and ALT
C. Blood urea nitrogen (BUN) and creatinine
D. White blood cell count and platelets
Answer: C
, Conceptual Explanation: Aminoglycosides like Gentamicin are nephrotoxic; monitoring
renal function (BUN/Creatinine) is critical.
5. A patient is prescribed Rifampin for tuberculosis. What is a key teaching point regarding
this medication?
A. Take the medication with high-fat meals.
B. Expect body fluids to turn orange-red.
C. Stop the medication once symptoms improve.
D. Avoid sun exposure due to photosensitivity.
Answer: B
Conceptual Explanation: Rifampin commonly causes a harmless discoloration of urine,
sweat, and tears.
6. What is the primary mechanism of action of Warfarin?
A. Blocking the activation of clotting factors II, VII, IX, and X
B. Inhibiting the conversion of fibrinogen to fibrin
C. Activating antithrombin III
D. Directly inhibiting Factor Xa
Answer: A
Conceptual Explanation: Warfarin inhibits Vitamin K epoxide reductase, preventing the
synthesis of Vitamin K-dependent clotting factors.
