,Q1. A patient on long-term warfarin therapy is started on rifampin for tuberculosis.
The international normalized ratio (INR) drops from 2.5 to 1.3 after two weeks.
Which mechanism best explains this interaction?
A. Rifampin displaces warfarin from plasma protein binding sites, increasing free
warfarin and metabolism.
B. Rifampin induces CYP2C9, accelerating warfarin metabolism and reducing its
anticoagulant effect.
C. Rifampin inhibits vitamin K epoxide reductase, enhancing warfarin's effect.
D. Rifampin increases renal clearance of warfarin, lowering plasma levels.
Correct Answer: B. Rifampin induces CYP2C9, accelerating warfarin metabolism
and reducing its anticoagulant effect.
Rationale: Rifampin is a potent enzyme inducer, particularly of CYP2C9, which
metabolizes S-warfarin. Induction increases warfarin metabolism, decreasing its
anticoagulant effect and INR. Displacement from protein binding would transiently
increase effect, not decrease. Inhibition of VKOR would enhance warfarin, and renal
clearance is not a major pathway for warfarin.
Why Wrong:
A - Displacement from protein binding would transiently increase free warfarin and
enhance effect, not reduce INR.
C - Rifampin does not inhibit vitamin K epoxide reductase; warfarin does.
D - Warfarin is primarily metabolized by the liver, not excreted renally to a significant
extent.

Q2. A nurse is caring for a patient with severe hypertension who is receiving
intravenous nitroprusside. The patient develops tachycardia, diaphoresis, and
metabolic acidosis. Which action is most appropriate?
A. Administer sodium thiosulfate as an antidote.
B. Discontinue the infusion and prepare to administer hydroxocobalamin.
C. Slow the infusion rate and monitor blood pressure every 5 minutes.
D. Obtain a serum methemoglobin level and prepare for methylene blue administration.
Correct Answer: B. Discontinue the infusion and prepare to administer
hydroxocobalamin.
Rationale: The symptoms suggest cyanide toxicity, a complication of prolonged
nitroprusside infusion. Nitroprusside releases cyanide, which can accumulate and cause
cellular hypoxia, metabolic acidosis, and tachycardia. Discontinuation and administration
of hydroxocobalamin (or sodium thiosulfate) is the treatment. Sodium thiosulfate is also
used, but hydroxocobalamin is the preferred first-line antidote.
Page 3
, Why Wrong:
A - Sodium thiosulfate is an antidote, but hydroxocobalamin is preferred as first-line;
also, the immediate action is to discontinue the infusion.
C - Slowing the infusion would not address the ongoing cyanide toxicity and could
worsen the acidosis.
D - Methemoglobinemia is not the primary issue; cyanide toxicity is.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 18
Q3. A patient is prescribed digoxin for heart failure. Which finding would increase
the risk of digoxin toxicity?
A. Serum potassium of 3.0 mEq/L
B. Serum magnesium of 2.2 mEq/L
C. Serum calcium of 9.0 mg/dL
D. Serum creatinine of 0.8 mg/dL
Correct Answer: A. Serum potassium of 3.0 mEq/L
Rationale: Hypokalemia (low potassium) increases the sensitivity of the myocardium to
digoxin, predisposing to toxicity. Normal magnesium, calcium, and renal function are not
risk factors; in fact, hypercalcemia and hypomagnesemia can also increase risk, but
hypokalemia is the classic and most significant.
Why Wrong:
B - Normal magnesium does not increase risk; hypomagnesemia would.
C - Normal calcium is not a risk factor; hypercalcemia would.
D - Normal renal function is not a risk factor; impaired renal function would increase
digoxin levels.

Q4. A patient with type 2 diabetes is on metformin and is scheduled for a CT scan
with IV contrast. Which action is most appropriate?
A. Hold metformin on the day of the procedure and for 48 hours after.
B. Administer metformin as usual, as it has no interaction with contrast.
C. Switch metformin to insulin for the procedure.
D. Increase metformin dose to maintain glycemic control during fasting.
Correct Answer: A. Hold metformin on the day of the procedure and for 48 hours
after.
Rationale: IV contrast can cause acute kidney injury, and metformin is renally cleared;
lactic acidosis risk increases with renal impairment. Therefore, metformin should be held
at the time of the procedure and for 48 hours afterward, and resumed only after renal
function is confirmed normal.
