, Question 1
A patient on chronic warfarin therapy is prescribed
trimethoprim-sulfamethoxazole for a urinary tract infection. Which mechanism
best explains the anticipated INR elevation?
A. Induction of CYP2C9 increasing warfarin clearance
B. Inhibition of CYP2C9 reducing warfarin metabolism
C. Displacement of warfarin from albumin without enzyme effect
D. Enhanced vitamin K absorption increasing clotting factor synthesis
Correct Answer: B - Inhibition of CYP2C9 reducing warfarin
metabolism
RATIONALE
Trimethoprim-sulfamethoxazole inhibits CYP2C9, the primary
enzyme metabolizing S-warfarin, leading to increased warfarin levels
and INR. Displacement from albumin is minor compared to metabolic
inhibition. Induction would lower INR, and enhanced vitamin K
absorption would oppose warfarin, not elevate INR.
Question 2
Which parameter is most critical when determining the initial vancomycin dose
for a patient with augmented renal clearance (ARC)?
A. Serum creatinine only
B. Creatinine clearance estimated by Cockcroft-Gault
C. Trough concentration drawn before the third dose
D. Actual body weight and measured creatinine clearance
Correct Answer: D - Actual body weight and measured creatinine
clearance
Page 2
, RATIONALE
Vancomycin dosing requires accurate renal function assessment; ARC
increases clearance, necessitating higher doses. Measured creatinine
clearance (e.g., 24-hour urine) with actual body weight is most
reliable, as Cockcroft-Gault may overestimate renal function in ARC.
Trough levels guide subsequent dosing but not initial dose.
Question 3
A patient with heart failure and reduced ejection fraction is started on
sacubitril/valsartan. Which concurrent medication requires immediate
discontinuation due to a black box warning?
A. Spironolactone
B. Carvedilol
C. Lisinopril
D. Furosemide
Correct Answer: C - Lisinopril
RATIONALE
Sacubitril/valsartan carries a black box warning for angioedema when
used with ACE inhibitors; a 36-hour washout is required.
Beta-blockers, mineralocorticoid antagonists, and loop diuretics are
standard combination therapy. Lisinopril must be stopped to avoid
life-threatening angioedema.
Question 4
Which statement best describes the clinical implication of the CYP2D6 poor
metabolizer phenotype for codeine prescribing?
A. Increased conversion to morphine, risking toxicity
B. Reduced conversion to morphine, resulting in inadequate analgesia
C. No effect because codeine acts directly on opioid receptors
D. Enhanced renal clearance of codeine requiring higher doses
Page 3
, Correct Answer: B - Reduced conversion to morphine, resulting
in inadequate analgesia
RATIONALE
Codeine is a prodrug requiring CYP2D6 conversion to morphine for
analgesia. Poor metabolizers produce little morphine, leading to
inadequate pain relief. Ultrarapid metabolizers risk toxicity. Codeine
does not act directly on opioid receptors.
Question 5
A patient on lithium therapy develops hypothyroidism. Which mechanism
explains this adverse effect?
A. Inhibition of thyroid hormone synthesis and release
B. Increased thyroid hormone metabolism by hepatic enzymes
C. Autoimmune destruction of thyroid tissue
D. Blockade of TSH receptors on the thyroid gland
Correct Answer: A - Inhibition of thyroid hormone synthesis and
release
RATIONALE
Lithium concentrates in the thyroid and inhibits iodination of tyrosine
and release of thyroid hormones, leading to hypothyroidism. It does
not induce hepatic enzymes, cause autoimmune destruction, or block
TSH receptors. Monitoring TSH is essential during lithium therapy.
Question 6
Which insulin regimen best mimics physiologic insulin secretion for a patient
with type 1 diabetes?
A. NPH twice daily with regular insulin sliding scale
B. Basal insulin glargine once daily plus rapid-acting insulin analog at
meals
C. Premixed 70/30 insulin twice daily
