,Question 1:
Which antifungal agent is considered the drug of choice for most life-
threatening systemic mycoses?
A. Fluconazole
B. Itraconazole
C. Amphotericin B
D. Caspofungin
Answer: C. Amphotericin B
Expert Explanation: Amphotericin B is identified in the study guide as the
broad-spectrum drug of choice for most systemic mycoses and is reserved
for severe, often life-threatening infections despite its significant toxicity.
Question 2:
What is the primary reason amphotericin B must be administered
intravenously for systemic infections?
A. It is extensively metabolized by the liver
B. It is poorly absorbed from the gastrointestinal tract
C. It is inactivated by gastric acid
D. It causes severe esophageal irritation when taken orally
Answer: B. It is poorly absorbed from the gastrointestinal tract
Expert Explanation: The guide notes that amphotericin B is poorly absorbed
when given orally, so systemic therapy requires IV administration to
achieve therapeutic plasma levels.
Question 3:
Which strategy best helps minimize nephrotoxicity during amphotericin B
therapy?
A. Co-administration with loop diuretics
B. Increasing the dose to shorten treatment duration
C. Infusing 1 liter of normal saline on treatment days
D. Giving daily NSAIDs for infusion-related pain
,Answer: C. Infusing 1 liter of normal saline on treatment days
Expert Explanation: The study guide specifically recommends infusing 1 L
of saline on the days amphotericin B is given and avoiding other
nephrotoxic drugs to reduce kidney damage.
Question 4:
In older adults, which key concern should the prescriber prioritize when
using azole antifungals such as itraconazole?
A. Increased risk of hypoglycemia from reduced insulin needs
B. Poor oral absorption due to achlorhydria and multiple drug interactions
C. Risk of irreversible ototoxicity
D. Development of agranulocytosis
Answer: B. Poor oral absorption due to achlorhydria and multiple drug
interactions
Expert Explanation: The guide highlights that older adults more frequently
have achlorhydria, making absorption of some antifungals unpredictable,
and azoles inhibit CYP450, significantly increasing levels of drugs such as
warfarin and oral hypoglycemics.
Question 5:
Which medication interaction is most concerning when prescribing
itraconazole?
A. Concurrent administration with acetaminophen
B. Concurrent use with warfarin
C. Concurrent use with amoxicillin
D. Concurrent use with nitrofurantoin
Answer: B. Concurrent use with warfarin
Expert Explanation: Itraconazole is a CYP3A4 inhibitor and can increase
serum levels of drugs like warfarin, raising bleeding risk and requiring close
monitoring or alternative therapy.
, Question 6:
Which statement best describes the role of caspofungin in systemic fungal
infections?
A. It is the first-line oral agent for tinea pedis
B. It is the preferred initial agent for all Candida infections
C. It is an IV option for invasive Candida or Aspergillus unresponsive to
amphotericin B or itraconazole
D. It is contraindicated in neutropenic patients
Answer: C. It is an IV option for invasive Candida or Aspergillus
unresponsive to amphotericin B or itraconazole
Expert Explanation: Caspofungin is indicated as an IV echinocandin used
for invasive aspergillosis in patients who fail or cannot tolerate amphotericin
B or itraconazole and for systemic Candida infections.
Question 7:
Which adverse effect profile is most characteristic of caspofungin therapy?
A. Severe nephrotoxicity with dose-dependent hearing loss
B. Histamine-mediated infusion reactions with fever, flushing, and phlebitis
C. Profound bone marrow suppression with agranulocytosis
D. Retinal toxicity with visual disturbances
Answer: B. Histamine-mediated infusion reactions with fever, flushing, and
phlebitis
Expert Explanation: The guide notes that caspofungin commonly causes
infusion-related reactions like rash, flushing, pruritus, phlebitis, and
systemic symptoms mediated by histamine release.
Question 8:
Which superficial fungal infection is most appropriately treated with oral
griseofulvin as standard therapy?
A. Tinea pedis
