Question 1
A 68-year-old male with a history of heart failure is prescribed itraconazole for a
systemic fungal infection. He is currently taking atorvastatin for hyperlipidemia and
omeprazole for GERD. Which of the following is the most appropriate intervention to
ensure safe and effective therapy?
A. Continue all medications as prescribed and monitor liver function tests monthly.
B. Discontinue omeprazole and increase the itraconazole dose to overcome reduced
absorption.
C. Hold the atorvastatin, separate itraconazole administration from omeprazole by at
least 2 hours, and monitor for signs of rhabdomyolysis.
D. Switch itraconazole to amphotericin B due to the contraindication in heart failure
and the drug interaction with atorvastatin.
Answer: C. Hold the atorvastatin, separate itraconazole administration from
omeprazole by at least 2 hours, and monitor for signs of rhabdomyolysis.
Rationale: Itraconazole requires an acidic gastric environment for absorption;
proton pump inhibitors like omeprazole significantly reduce its absorption. The
drug should be given 1 hour before or 2 hours after the PPI. Additionally,
itraconazole is a potent CYP3A4 inhibitor and will increase atorvastatin levels,
raising the risk of rhabdomyolysis. Holding atorvastatin during itraconazole
therapy or using a statin less dependent on CYP3A4 (e.g., pravastatin) is
recommended. Itraconazole is contraindicated in heart failure, but option D is
incorrect because switching to amphotericin B is not the first intervention; the
prescriber should instead address the drug interactions and consider an
alternative antifungal if heart failure is severe. Option A ignores critical
interactions, and Option B is dangerous because increasing the dose does not fix
the absorption problem and would worsen toxicity.

Question 2
A 45-year-old female is prescribed griseofulvin for a stubborn tinea corporis
infection. She asks how the medication works and what to expect. Which statement
accurately reflects the pharmacology and use of griseofulvin?
A. It is fungicidal and achieves high systemic levels when taken with fatty foods.
B. It is effective against both dermatophytes and Candida species.
C. It binds to keratin precursors, making newly formed skin resistant to fungal
invasion.
D. It is administered intravenously for severe systemic mycoses.
Answer: C. It binds to keratin precursors, making newly formed skin resistant to
fungal invasion.
Rationale: Griseofulvin is a fungistatic agent that deposits in keratin precursor
cells, rendering new skin, hair, and nails resistant to dermatophyte invasion. It
is not effective against Candida or systemic fungi (eliminating B and D). While
taking it with fatty foods does enhance absorption, the drug is not directly
fungicidal (eliminating A); its primary mechanism is to inhibit fungal mitosis
and bind keratin.
Question 3
A patient with herpes zoster (shingles) is prescribed high-dose oral acyclovir. The
patient has a history of chronic kidney disease with a creatinine clearance of 45
mL/min. What is the most appropriate action regarding acyclovir dosing?
A. Prescribe the standard dose; acyclovir is hepatically metabolized and renal
impairment does not affect dosing.
B. Reduce the dose and extend the dosing interval based on renal function.
C. Switch to IV acyclovir because oral absorption is unreliable in renal disease.
D. Increase the dose to ensure adequate CNS penetration.

Answer: B. Reduce the dose and extend the dosing interval based on renal
function.
Rationale: Acyclovir is primarily eliminated renally via glomerular filtration
and tubular secretion. In patients with renal impairment (CrCl < 50 mL/min),
the dose must be reduced and the interval extended to prevent neurotoxicity
and crystalluria. Option A is incorrect because acyclovir is not hepatically
metabolized to a significant degree. Option C is incorrect; IV acyclovir is
reserved for severe infections like encephalitis, not routine shingles, and would
further burden renal function. Option D would increase toxicity.
Question 4
A 72-year-old male is started on oseltamivir for confirmed influenza A, 60 hours after
symptom onset. Which statement best reflects the evidence-based use of oseltamivir
in this scenario?
A. Oseltamivir is most effective when started within 48 hours; however, it may still
provide benefit in hospitalized or high-risk patients beyond that window.
B. Oseltamivir is ineffective after 48 hours and should not be prescribed.
C. Oseltamivir should be given at double the standard dose for late initiation.
D. Oseltamivir is contraindicated in patients over 65 years old.
Answer: A. Oseltamivir is most effective when started within 48 hours; however,
it may still provide benefit in hospitalized or high-risk patients beyond that
window.
Rationale: The neuraminidase inhibitor oseltamivir has maximal efficacy when
initiated within 48 hours of symptom onset. However, guidelines support its use
beyond 48 hours in hospitalized, severely ill, or high-risk patients (elderly,
immunocompromised) as it may still reduce viral shedding and complications.
Option B is too absolute. Option C is incorrect; no dose doubling is
