Question 1
A patient with type 2 diabetes mellitus is prescribed metformin. Which
of the following is the primary mechanism of action of this medication?
A) Increases insulin secretion from pancreatic beta cells
B) Decreases hepatic glucose production and improves insulin
sensitivity
C) Slows the absorption of carbohydrates in the gastrointestinal tract
D) Activates peroxisome proliferator-activated receptor-gamma
Answer: B
Explanation: Metformin is a biguanide that primarily reduces hepatic
gluconeogenesis and enhances peripheral insulin sensitivity. It does not
directly stimulate insulin secretion, making hypoglycemia less likely than
with sulfonylureas. Option A describes sulfonylureas, C describes alpha-
glucosidase inhibitors, and D describes thiazolidinediones.
Question 2

A 72-year-old patient with heart failure and reduced ejection fraction is
initiated on carvedilol. What pharmacological property makes
carvedilol particularly beneficial in this population?
A) Selective beta-1 receptor antagonism
B) Alpha-1 receptor antagonism with antioxidant effects
C) Pure beta-2 receptor agonism
D) Inhibition of angiotensin-converting enzyme
Answer: B
Explanation: Carvedilol is a non-selective beta-blocker with additional
alpha-1 blocking activity, which causes vasodilation and reduces
afterload. It also possesses antioxidant properties that may reduce
oxidative stress in failing myocardium. Unlike metoprolol, it is not beta-
1 selective, and it does not inhibit ACE.
Question 3
A patient is receiving vancomycin for a methicillin-resistant
Staphylococcus aureus infection. Which adverse effect requires
therapeutic drug monitoring to prevent?
A) Hepatotoxicity
B) Nephrotoxicity and ototoxicity
C) Cardiotoxicity
D) Bone marrow suppression
Answer: B
Explanation: Vancomycin is associated with nephrotoxicity and
ototoxicity, particularly when trough levels exceed 20 mcg/mL.
,3|Page
Monitoring serum concentrations helps minimize these risks while
ensuring efficacy. Hepatotoxicity and bone marrow suppression are not
typical vancomycin toxicities.
Question 4
Which of the following pharmacokinetic changes in the elderly most
significantly affects drug dosing?
A) Increased hepatic blood flow
B) Decreased glomerular filtration rate
C) Increased total body water
D) Increased serum albumin levels
Answer: B
Explanation: Renal function declines with age, reducing glomerular
filtration rate and drug clearance, especially for renally eliminated
medications. Hepatic blood flow decreases, not increases. Total body
water decreases, and serum albumin may decrease, affecting protein
binding.
Question 5
A patient on warfarin has an International Normalized Ratio of 5.0
without bleeding. Which of the following is the most appropriate
management?
A) Administer vitamin K 10 mg intravenously
B) Hold warfarin and restart at a lower dose when INR is therapeutic
C) Administer fresh frozen plasma immediately
, 4|Page
D) Increase warfarin dose to achieve therapeutic range
Answer: B
Explanation: For an asymptomatic patient with INR between 5 and 9,
holding warfarin is standard, with restarting at a lower dose when INR
returns to range. Vitamin K is reserved for bleeding or very high INR.
Fresh frozen plasma is for urgent reversal with bleeding.
Question 6
A patient with severe asthma is prescribed a corticosteroid inhaler.
Which statement best reflects the mechanism of action of inhaled
corticosteroids?
A) Direct bronchodilation via beta-2 receptor stimulation
B) Inhibition of phospholipase A2, reducing arachidonic acid production
C) Antagonism of leukotriene receptors
D) Stabilization of mast cell membranes
Answer: B
Explanation: Corticosteroids inhibit phospholipase A2, decreasing the
release of arachidonic acid and subsequent synthesis of prostaglandins
and leukotrienes. This reduces airway inflammation. Beta-2 agonists
cause bronchodilation, leukotriene receptor antagonists block
leukotrienes, and cromolyn stabilizes mast cells.
