NR 566 Midterm Exam Set 1
1. Which antifungal agent requires a patient to avoid simvastatin due to the risk
of rhabdomyolysis from CYP3A4 inhibition?
A. Fluconazole
B. Itraconazole
C. Terbinafine
D. Griseofulvin
Answer: B. Itraconazole
Expert Rationale: Itraconazole potently inhibits the CYP3A4 enzyme, significantly
increasing plasma concentrations of HMG-CoA reductase inhibitors like
simvastatin, leading to myopathy and rhabdomyolysis. Prescribers must either
switch to pravastatin (which is not metabolized by CYP3A4) or select an alternative
antifungal agent.
2. What is the standard loading dose for caspofungin when treating invasive
aspergillosis?
A. 50 mg IV
B. 70 mg IV
, C. 100 mg IV
D. 150 mg IV
Answer: B. 70 mg IV
Expert Rationale: Caspofungin requires a 70 mg intravenous loading dose on day
one, followed by 50 mg daily thereafter, to achieve therapeutic plasma levels
quickly. This echinocandin is reserved for refractory invasive aspergillosis or
candidiasis when azoles or amphotericin B are contraindicated.
3. Which antifungal medication deposits in keratin precursor cells of skin, hair,
and nails to prevent fungal invasion of newly formed keratin?
A. Fluconazole
B. Griseofulvin
C. Amphotericin B
D. Caspofungin
Answer: B. Griseofulvin
Expert Rationale: Griseofulvin is fungistatic and accumulates in keratin precursor
cells, making new keratin resistant to fungal penetration. As infected keratin is
shed and replaced, the infection resolves, requiring 6–8 weeks for scalp infections
and up to a year for nails.
4. What is the recommended duration of oral terbinafine therapy for toenail
onychomycosis?
A. 2 weeks
B. 6 weeks
C. 12 weeks
D. 24 weeks
Answer: C. 12 weeks
Expert Rationale: Terbinafine 250 mg daily requires 12 weeks for toenail
infections and 6 weeks for fingernail infections due to slower toenail growth rates.
Its fungicidal activity against dermatophytes and accumulation in the nail plate
provide high cure rates compared to azole therapy.
