,Q1. A patient with a history of chronic renal insufficiency (eGFR 25 mL/min/1.73m²) is prescribed a
medication that is primarily eliminated unchanged by the kidneys. The drug has a narrow therapeutic index.
Which of the following pharmacokinetic alterations is most critical to consider when determining the
appropriate dosing regimen?
A. Increased volume of distribution due to fluid overload
B. Decreased protein binding leading to higher free drug concentrations
C. Reduced clearance with prolonged elimination half-life
D. Enhanced hepatic metabolism as a compensatory mechanism
Correct Answer: C. Reduced clearance with prolonged elimination half-life
Rationale: In renal insufficiency, clearance of renally eliminated drugs is reduced, leading to a prolonged half-life.
For a drug with a narrow therapeutic index, this accumulation risk necessitates dose adjustment (reduced dose or
extended interval). Option A may occur but is not the primary concern for dosing. Option B is less likely for drugs
that are not highly protein-bound. Option D is not a reliable compensatory mechanism and often hepatic
metabolism is impaired in uremia.
Why Wrong:
A - Increased volume of distribution may occur but does not directly address the primary risk of drug
accumulation due to reduced elimination.
B - Decreased protein binding is relevant for highly protein-bound drugs, but the question specifies
elimination unchanged by kidneys, not protein binding.
D - Hepatic metabolism is not typically enhanced in renal insufficiency; instead, it may be impaired, and this
is not a reliable compensatory mechanism.

Q2. A patient is receiving a continuous intravenous infusion of heparin for the treatment of acute venous
thromboembolism. The current aPTT is 72 seconds (therapeutic range 60-80 seconds). The nurse notes that
the infusion pump is set to deliver 18 mL/hour, and the heparin concentration is 50 units/mL. The patient
weighs 85 kg. What is the current infusion rate in units/kg/hour?
A. 10.6 units/kg/hr
B. 12.4 units/kg/hr
C. 14.2 units/kg/hr
D. 16.8 units/kg/hr
Correct Answer: A. 10.6 units/kg/hr
Rationale: The infusion delivers 18 mL/hr × 50 units/mL = 900 units/hr. For an 85 kg patient, 900 units/hr ÷ 85 kg
= 10.588 10.6 units/kg/hr. This is within typical initial dosing ranges (10-15 units/kg/hr). Option B would
correspond to ~1050 units/hr, C to ~1200, D to ~1428, none of which match the calculation.
Why Wrong:
B - 12.4 units/kg/hr would require a higher infusion rate (approximately 21 mL/hr) not consistent with the
given data.
C - 14.2 units/kg/hr corresponds to ~1207 units/hr, which is not achieved with the current settings.
D - 16.8 units/kg/hr would require ~1428 units/hr, significantly above the actual delivery.

, Q3. A nurse is preparing to administer a medication via a nasogastric tube. The tablet formulation is an
extended-release product that cannot be crushed. Which of the following is the most appropriate action?
A. Crush the tablet and mix with 30 mL of water before administration.
B. Contact the prescriber to request a change to an immediate-release liquid formulation.
C. Dissolve the tablet in warm water and administer via the tube.
D. Administer the whole tablet through the tube if the lumen is large enough.
Correct Answer: B. Contact the prescriber to request a change to an immediate-release liquid formulation.
Rationale: Extended-release tablets should not be crushed as it can lead to dose dumping and toxicity. The safest
action is to contact the prescriber for an alternative formulation (e.g., immediate-release liquid or a different
drug). Option A and C are dangerous. Option D is not feasible as whole tablets cannot pass through a nasogastric
tube and may cause obstruction.
Why Wrong:
A - Crushing an extended-release formulation destroys the release mechanism, risking immediate release of
the entire dose.
C - Dissolving may still compromise the extended-release properties and could cause tube clogging.
D - Whole tablets are too large for nasogastric tubes and cannot be administered intact.

Q4. A patient is prescribed vancomycin 1.5 g intravenously every 12 hours. The pharmacy supplies
vancomycin in 250 mL of 0.9% sodium chloride. The recommended infusion rate for vancomycin is 10
mg/min to minimize the risk of red man syndrome. How many minutes should the infusion run?
A. 150 minutes
B. 120 minutes
C. 90 minutes
D. 60 minutes
Correct Answer: A. 150 minutes
Rationale: The dose is 1.5 g = 1500 mg. At a rate of 10 mg/min, the infusion time is 1500 mg ÷ 10 mg/min = 150
minutes. This is consistent with standard practice to administer vancomycin over at least 1 hour per gram. Option
B would correspond to 12.5 mg/min, C to 16.7 mg/min, D to 25 mg/min, all exceeding the recommended rate.
Why Wrong:
B - 120 minutes would require an infusion rate of 12.5 mg/min, exceeding the recommended 10 mg/min.
C - 90 minutes corresponds to 16.7 mg/min, which increases the risk of red man syndrome.
D - 60 minutes would be 25 mg/min, far above the safe rate.
