Q1.
A patient with type 2 diabetes and chronic kidney disease (eGFR 30 mL/min) is prescribed
metformin. Which pharmacokinetic property is most likely to increase the risk of lactic
acidosis in this patient?
A. Decreased renal clearance leading to B. Increased hepatic metabolism producing
drug accumulation toxic metabolites
C. Altered protein binding increasing free D. Reduced gastrointestinal absorption
drug concentration altering drug efficacy
Correct: A - Decreased renal clearance leading to drug accumulation
Rationale:Metformin is excreted unchanged by the kidneys. In CKD, reduced renal clearance
causes accumulation, increasing the risk of lactic acidosis. Hepatic metabolism is minimal,
protein binding is negligible, and absorption is not the primary concern.
Q2.
A patient on warfarin requires an antibiotic for a urinary tract infection. Which antibiotic
class is most likely to potentiate warfarin's anticoagulant effect by inhibiting its
metabolism?
A. Penicillins B. Macrolides
C. Aminoglycosides D. Tetracyclines
Correct: B - Macrolides
Rationale:Macrolides (e.g., clarithromycin, erythromycin) inhibit CYP3A4, the enzyme that
metabolizes warfarin, leading to increased INR and bleeding risk. Penicillins and
aminoglycosides have minimal interaction, and tetracyclines may affect gut flora but not
directly inhibit CYP3A4.
Q3.
A patient with heart failure is started on sacubitril/valsartan. Which laboratory value
requires close monitoring during the first month of therapy?
A. Serum potassium B. Serum creatinine and potassium
C. Liver enzymes D. Complete blood count
Page 3
, Section A - Nur-641e PREP ALL Possible AND Updates 100 Correct GCU Advanced Nursing Pharmacology AND Therapeutics Graduate
Correct: B - Serum creatinine and potassium
Rationale:Sacubitril/valsartan can cause hyperkalemia and worsening renal function,
especially in patients with heart failure. Monitoring serum creatinine and potassium is
essential. Liver enzymes and CBC are not routinely monitored for this drug.
Q4.
A patient with generalized anxiety disorder is prescribed buspirone. Which characteristic
of buspirone's mechanism differentiates it from benzodiazepines?
A. It potentiates GABA-mediated chloride B. It is a partial agonist at serotonin 5-HT1A
influx receptors
C. It blocks dopamine D2 receptors D. It inhibits the reuptake of norepinephrine
Correct: B - It is a partial agonist at serotonin 5-HT1A receptors
Rationale:Buspirone is a partial agonist at 5-HT1A receptors, reducing serotonin activity,
which alleviates anxiety without causing sedation or dependence. Benzodiazepines enhance
GABA. Dopamine blockade is typical of antipsychotics, and norepinephrine reuptake inhibition
is seen in SNRIs.
Q5.
A patient is prescribed albuterol for asthma. Which adverse effect is most likely due to
beta-2 receptor stimulation in skeletal muscle?
A. Tachycardia B. Tremor
C. Hypokalemia D. Nervousness
Correct: B - Tremor
Rationale:Beta-2 receptors are present on skeletal muscle; stimulation causes tremor.
Tachycardia is from beta-1 effects, hypokalemia from beta-2 stimulation of sodium-potassium
ATPase, but tremor is the most direct muscle effect. Nervousness is a CNS effect.
Q6.
A patient on digoxin presents with nausea, visual disturbances, and a heart rate of 48
bpm. Which intervention is most appropriate?
A. Administer digoxin immune Fab B. Hold digoxin and draw serum digoxin
level
C. Give atropine to increase heart rate D. Start potassium replacement
Correct: B - Hold digoxin and draw serum digoxin level
