Exam 4 Blueprint Practice Questions
Section 1: Basic Questions About Antifungals
Question 1 Which of the following is an opportunistic systemic fungal infection?
• A) Sporotrichosis
• B) Aspergillosis
• C) Blastomycosis
• D) Histoplasmosis
Answer: B Rationale: Opportunistic systemic fungal infections occur in immunocompromised
patients and include Aspergillosis, Candidiasis, Cryptococcosis, and Mucormycosis. Non-
opportunistic infections, such as sporotrichosis, blastomycosis, and histoplasmosis, affect healthy
individuals.
Question 2 What is the drug of choice (DOC) for most systemic fungal infections?
• A) Fluconazole
• B) Amphotericin B
• C) Itraconazole
• D) Ketoconazole
Answer: B Rationale: Amphotericin B is the DOC for most systemic fungal infections due to its
broad-spectrum antifungal activity, despite its high toxicity.
Question 3 Which antifungal is effective against both systemic and superficial fungal
infections but has a black box warning for patients with heart failure?
• A) Amphotericin B
• B) Itraconazole
• C) Fluconazole
• D) Terbinafine
Answer: B Rationale: Itraconazole is effective for both systemic and superficial fungal
infections but has a BBW due to its negative inotropic effects, contraindicating its use in patients
with heart failure.
Question 4 Which antifungal is primarily used to treat superficial fungal infections, such as
candidiasis?

, • A) Amphotericin B
• B) Fluconazole
• C) Itraconazole
• D) Ketoconazole
mailto:https://www.stuvia.com/user/Wisdoms 2
,Answer: B Rationale: Fluconazole is a commonly prescribed antifungal for superficial
infections like candidiasis and cryptococcal meningitis.
Question 5 Which organism is responsible for the majority of cases of superficial fungal
infections?
• A) Candida albicans
• B) Aspergillus spp.
• C) Cryptococcus neoformans
• D) Mucorales spp.
Answer: A Rationale: Candida albicans is a common cause of superficial fungal infections,
particularly involving mucosal surfaces, skin, and nails.
Question 6 What is the primary safety concern associated with Amphotericin B?
• A) Hepatotoxicity
• B) Nephrotoxicity and infusion reactions
• C) Cardiotoxicity
• D) Ototoxicity
Answer: B Rationale: Amphotericin B has significant nephrotoxicity and infusion-related
reactions, limiting its use to life-threatening fungal infections.
Question 7 Which antifungal is the DOC for histoplasmosis and blastomycosis?
• A) Amphotericin B
• B) Fluconazole
• C) Itraconazole
• D) Ketoconazole
Answer: C Rationale: Itraconazole is the preferred agent for non-opportunistic systemic
infections such as histoplasmosis and blastomycosis.
Question 8 What is the recommended antifungal for cryptococcal meningitis?
• A) Amphotericin B
• B) Itraconazole
• C) Fluconazole
• D) Terbinafine
Answer: C Rationale: Fluconazole is effective in treating cryptococcal meningitis, particularly
in immunocompromised patients.
Question 9 Which antifungal carries the highest risk for systemic toxicity and is reserved
for life-threatening infections?
mailto:https://www.stuvia.com/user/Wisdoms 3
, • A) Fluconazole
7
• B) Amphotericin B
7 7
• C) Itraconazole
7
• D) Voriconazole
7
Answer: B Rationale: Amphotericin B is highly effective but carries a significant risk of
7 7 7 7 7 7 7 7 7 7 7 7 7
nephrotoxicity and other adverse effects, making it reserved for severe infections.

Question 10 What is the mechanism of action of Azole antifungals like Itraconazole and
7 7 7 7 7 7 7 7 7 7 7 7 7
Fluconazole?
7
• A) Inhibit DNA synthesis
7 7 7
• B) Inhibit cell wall synthesis
7 7 7 7
• C) Inhibit ergosterol synthesis in fungal cell membranes
7 7 7 7 7 7 7
• D) Disrupt protein synthesis
7 7 7
Answer: C Rationale: Azole antifungals inhibit the synthesis of ergosterol, a critical component
7 7 7 7 7 7 7 7 7 7 7 7
of fungal cell membranes, disrupting fungal growth and survival.

loss. A biopsy confirms Histoplasma capsulatum. Which antifungal is the DOC for this systemic
7 7 7 7 7 7 7 7 7 7 7 7 7 7
infection?
7
• A) Amphotericin B
7 7
• B) Itraconazole
7
• C) Fluconazole
7
• D) Ketoconazole
7
Answer: B Rationale: Itraconazole is the preferred antifungal for treating systemic infections
7 7 7 7 7 7 7 7 7 7 7
like histoplasmosis, offering a less toxic alternative to Amphotericin B.
7 7 7 7 7 7 7 7 7 7
Question 12 A 65-year-old diabetic man presents with fever, cough, and hemoptysis. Imaging
7 7 7 7 7 7 7 7 7 7 7 7
reveals lung nodules, and culture grows Aspergillus fumigatus. Which antifungal is most
7 7 7 7 7 7 7 7 7 7 7 7
appropriate?
7
• A) Fluconazole
7
• B) Amphotericin B
7 7
• C) Itraconazole
7
• D) Ketoconazole
7
Answer: B Rationale: Amphotericin B is the DOC for systemic aspergillosis due to its broad-
7 7 7 7 7 7 7 7 7 7 7 7 7 7
spectrum activity and efficacy in life-threatening infections.
