1. What is the primary purpose of administering a loading dose of a
medication?
A. To achieve therapeutic levels more quickly
B. To prevent side effects
C. To maintain drug levels within the therapeutic range
D. To reduce the frequency of dosing
Answer: A) To achieve therapeutic levels more quickly
Rationale: A loading dose is a higher dose given initially to rapidly achieve

2. What is the action of antiplatelet drugs like aspirin?
A. They inhibit the formation of clotting factors in the liver
B. They block the aggregation of platelets
C. They increase blood clotting
D. They increase red blood cell production
Answer: B) They block the aggregation of platelets
Rationale: Antiplatelet drugs, such as aspirin, prevent platelets from sticking
together, thus reducing the risk of clot formation in arteries.
3. What is the mechanism of action of warfarin?
,A. Inhibits platelet aggregation
B. Inhibits vitamin K-dependent clotting factors
C. Increases clotting factor production
D. Inhibits thrombin directly
Answer: B) Inhibits vitamin K-dependent clotting factors
Rationale: Warfarin works by inhibiting the synthesis of vitamin K-dependent
clotting factors, thus reducing the risk of blood clots.
4. Which of the following medications can cause hyperkalemia?

B. Furosemide
C. Hydrochlorothiazide

5. What is the primary use of proton pump inhibitors (PPIs)?
A. To treat bacterial infections
B. To reduce stomach acid production
C. To lower blood pressure
D. To manage diabetes
, Answer: B) To reduce stomach acid production
Rationale: PPIs decrease stomach acid, aiding in the healing of ulcers and
