,Q1. A patient on warfarin develops an INR of 5.2 without bleeding. Which intervention is most
appropriate for immediate reversal?
A. Administer vitamin K 10 mg orally
B. Administer vitamin K 1 mg intravenously
C. Administer fresh frozen plasma (FFP)
D. Administer prothrombin complex concentrate (PCC)
Correct Answer: A. Administer vitamin K 10 mg orally
Rationale: For an INR >4.5 without bleeding, oral vitamin K 10 mg is recommended for reversal. IV
vitamin K is reserved for serious bleeding; FFP and PCC are used for life-threatening bleeding. Oral
vitamin K is safer and effective in this scenario.
Why Wrong:
B - IV vitamin K is indicated for serious or life-threatening bleeding, not for elevated INR without
bleeding.
C - FFP is reserved for major bleeding when rapid reversal is needed, not for asymptomatic elevated
INR.
D - PCC is used for urgent reversal in major bleeding or before emergency surgery, not for
asymptomatic INR elevation.

Q2. Which of the following best explains why codeine is no longer recommended for pain
management in children?
A. Codeine has a higher risk of respiratory depression due to ultrarapid metabolism in some children
B. Codeine is less effective than ibuprofen for pediatric pain
C. Codeine causes more gastrointestinal side effects in children than adults
D. Codeine has a shorter half-life in children requiring more frequent dosing
Correct Answer: A. Codeine has a higher risk of respiratory depression due to ultrarapid
metabolism in some children
Rationale: Codeine is a prodrug metabolized by CYP2D6 to morphine. Ultrarapid metabolizers convert
codeine too quickly, leading to morphine accumulation and fatal respiratory depression. This risk led to a
black box warning and contraindication in children.
Why Wrong:
B - Effectiveness is not the primary reason; codeine can be effective, but safety concerns override.
C - GI side effects are not unique to children and not the reason for the contraindication.
D - Half-life differences are not the key issue; the pharmacogenetic risk is the main concern.

, Q3. A patient with type 2 diabetes and CKD stage 3 is prescribed metformin. What is the primary
rationale for monitoring renal function?
A. Metformin is nephrotoxic and can worsen kidney function
B. Metformin accumulates in renal impairment increasing risk of lactic acidosis
C. Metformin requires dose adjustment based on creatinine clearance to maintain efficacy
D. Renal impairment alters metformin absorption leading to hypoglycemia
Correct Answer: B. Metformin accumulates in renal impairment increasing risk of lactic acidosis
Rationale: Metformin is excreted renally unchanged. In CKD, accumulation increases the risk of lactic
acidosis, a rare but serious adverse effect. Guidelines recommend monitoring eGFR and discontinuing if
eGFR falls below 30 mL/min/1.73 m².
Why Wrong:
A - Metformin is not directly nephrotoxic; the concern is accumulation due to reduced clearance.
C - Efficacy is not the primary concern; safety is the main reason for monitoring renal function.
D - Absorption is not affected by renal function; elimination is the issue.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 45
Q4. Which of the following drug pairs exhibits a pharmacodynamic interaction that increases the
risk of QT prolongation?
A. Warfarin and aspirin
B. Sertraline and amitriptyline
C. Furosemide and digoxin
D. Omeprazole and clopidogrel
Correct Answer: B. Sertraline and amitriptyline
Rationale: Both sertraline (SSRI) and amitriptyline (tricyclic antidepressant) can prolong the QT
interval. Their combined use increases the risk of torsades de pointes. This is a pharmacodynamic
interaction where both drugs act on the same cardiac ion channels.
Why Wrong:
A - Warfarin and aspirin increase bleeding risk via pharmacodynamic interaction on hemostasis, not
QT prolongation.
C - Furosemide and digoxin interact via electrolyte depletion (hypokalemia) increasing digoxin
toxicity, not directly QT prolongation.
D - Omeprazole inhibits CYP2C19 reducing clopidogrel activation, a pharmacokinetic interaction,
not QT prolongation.
