,High-Yield Drug Classes (25 Questions)
Question 1
While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what
the action of the drug is. As a health care provider, you explain that the action of an ACE
inhibitor is
A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor
angiotensin II
B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output
and lowering blood pressure
C. To decrease heart rate and blood pressure by competing with Betal and Beta2
receptors in the heart and lungs
D. To lower blood glucose by stimulating the release of insulin
Correct Answer
A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor
angiotensin II
Rationale:
ACE inhibitors block angiotensin I conversion, reducing vasoconstriction, option B is incorrect as it describes
diuretics

,Question 2
A patient with type 2 diabetes is prescribed Metformin. What is the primary mechanism of
action of this medication?
A. To stimulate the release of insulin from the pancreas
B. To decrease glucose production in the liver
C. To increase the uptake of glucose by muscles
D. To slow gastric emptying and reduce glucagon secretion
Correct Answer
B. To decrease glucose production in the liver
Rationale:
Metformin decreases hepatic glucose production, option A is incorrect as it describes sulfonylureas
Question 3
A patient is experiencing symptoms of a migraine headache. Which of the following
medications is most likely to be prescribed?
A. Beta-blockers
B. Cholinesterase Inhibitors
C. Triptans
D. Antihistamines
Correct Answer
C. Triptans
Rationale:
Triptans are specific for migraine treatment, option A is incorrect as beta-blockers are for prevention

, Question 4
A patient with hypertension is prescribed a calcium channel blocker. What is the primary
effect of this medication on the cardiovascular system?
A. To increase cardiac contractility and heart rate
B. To decrease vascular resistance and lower blood pressure
C. To increase sodium reabsorption and fluid retention
D. To stimulate the sympathetic nervous system
Correct Answer
B. To decrease vascular resistance and lower blood pressure
Rationale:
Calcium channel blockers relax vascular smooth muscle, option A is incorrect as it describes positive
inotropes
Question 5
A patient is taking a medication for asthma. The medication is a bronchodilator that works
by stimulating beta-2 adrenergic receptors. What is the name of this type of medication?
A. Anticholinergic
B. Beta-agonist
C. Methylxanthine
D. Corticosteroid
Correct Answer
B. Beta-agonist
Rationale:
Beta-agonists stimulate beta-2 receptors, option A is incorrect as it describes a different mechanism
