Section 1: Basic Questions About Antifungals
n7 n7 n7 n7 n7




Question 1 Which of the following is an opportunistic systemic fungal infection?
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




• A) Sporotrichosisn7




• B) Aspergillosis n7




• C) Blastomycosis n7




• D) Histoplasmosisn7




Answer: B Rationale: Opportunistic systemic fungal infections occur in immunocompromised
n7 n7 n7 n7 n7 n7 n7 n7 n7




patients and include Aspergillosis, Candidiasis, Cryptococcosis, and Mucormycosis. Non-
n7 n7 n7 n7 n7 n7 n7 n7 n7




opportunistic infections, such as sporotrichosis, blastomycosis, and histoplasmosis, affect healthy
n7 n7 n7 n7 n7 n7 n7 n7 n7




individuals.

Question 2 What is the drug of choice (DOC) for most systemic fungal infections?
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




• A) Fluconazole n7




• B) Amphotericin Bn7 n7




• C) Itraconazole n7




• D) Ketoconazole n7




Answer: B Rationale: Amphotericin B is the DOC for most systemic fungal infections due to its
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




broad-spectrum antifungal activity, despite its high toxicity.

Question 3 Which antifungal is effective against both systemic and superficial fungal infections
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




but has a black box warning for patients with heart failure?

• A) Amphotericin Bn7 n7




• B) Itraconazole n7




• C) Fluconazole n7




• D) Terbinafine n7




Answer: B Rationale: Itraconazole is effective for both systemic and superficial fungal
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




infections but has a BBW due to its negative inotropic effects, contraindicating its use in patients
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7




with heart failure.
