,Q1. A patient with chronic heart failure (HFrEF) is prescribed sacubitril/valsartan.
Which laboratory value requires immediate evaluation before initiating therapy?
A. Serum potassium 5.2 mEq/L
B. Serum creatinine 1.1 mg/dL
C. BNP 450 pg/mL
D. Hemoglobin 12.0 g/dL
Correct Answer: A. Serum potassium 5.2 mEq/L
Rationale: Sacubitril/valsartan can cause hyperkalemia; a potassium >5.0 mEq/L is a
contraindication for initiation. Elevated BNP, mild creatinine elevation, or mild anemia
are not contraindications.
Why Wrong:
B - Creatinine 1.1 mg/dL is within normal limits and does not preclude use, though
monitoring is advised.
C - Elevated BNP indicates heart failure severity but is not a contraindication.
D - Mild anemia is not a contraindication for sacubitril/valsartan.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 24
Q2. Which pharmacokinetic principle best explains the need for a loading dose of
intravenous digoxin in acute atrial fibrillation?
A. First-pass hepatic metabolism reduces oral bioavailability
B. Large volume of distribution requires initial saturation to achieve therapeutic plasma
levels
C. Protein binding limits free drug concentration until binding sites are saturated
D. Renal clearance is delayed until steady state is achieved
Correct Answer: B. Large volume of distribution requires initial saturation to achieve
therapeutic plasma levels
Rationale: Digoxin has a large volume of distribution, so a loading dose is needed to
rapidly achieve therapeutic tissue and plasma levels. First-pass metabolism, protein
binding, or renal clearance do not explain the need for a loading dose.
Why Wrong:
A - First-pass metabolism affects oral bioavailability but is not the reason for a
loading dose.
C - Protein binding saturation is not a typical reason for loading doses.
D - Renal clearance does not delay steady state; loading doses bypass the time to
steady state.

, Q3. A patient on vancomycin for MRSA pneumonia has a trough of 24 mcg/mL.
Which intervention is most appropriate?
A. Continue current dose, recheck trough in 48 hours
B. Hold the next dose and repeat trough before next scheduled dose
C. Increase the dose to achieve a higher peak
D. Switch to oral vancomycin to reduce systemic exposure
Correct Answer: B. Hold the next dose and repeat trough before next scheduled dose
Rationale: A trough >20 mcg/mL is associated with nephrotoxicity; holding the dose and
reassessing is standard. Continuing or increasing would worsen toxicity; oral vancomycin
is not absorbed for systemic MRSA pneumonia.
Why Wrong:
A - Continuing the same dose would maintain toxic levels.
C - Increasing the dose would elevate trough further, increasing nephrotoxicity risk.
D - Oral vancomycin is not absorbed systemically and is ineffective for pneumonia.

Ed.
Q4. Which finding is most indicative of malignant hyperthermia in a postoperative
patient who received succinylcholine?
A. Temperature 38.5°C and sinus tachycardia
B. End-tidal CO2 65 mm Hg and muscle rigidity
C. Oxygen saturation 89% and hypotension
D. Urine output 20 mL/hr and serum potassium 5.8 mEq/L
Correct Answer: B. End-tidal CO2 65 mm Hg and muscle rigidity
Rationale: Malignant hyperthermia is characterized by hypermetabolism: rising ETCO2,
muscle rigidity, and rapid temperature increase. While fever and tachycardia occur, the
combination of elevated ETCO2 with rigidity is classic and early.
Why Wrong:
A - Fever and tachycardia are nonspecific and occur later.
C - Hypoxemia and hypotension are late signs, not specific.
D - Oliguria and hyperkalemia are secondary, not the earliest indicators.
Reference: Nagelhout, J.J. & Plaus, K. (2025). Nurse Anesthesia, 7th Ed., Ch. 15
Q5. A patient with opioid-induced respiratory depression is given naloxone. Which
assessment finding indicates the need for repeat dosing?
A. Increased pain without change in respiratory rate
B. Respiratory rate 8/min 30 minutes after administration
C. Blood pressure 140/90 mm Hg
