Section 1: Antifungal Pharmacology – Basic Concepts and Systemic
Infections
Q1: A 42-year-old patient with HIV/AIDS develops fever, cough, and hemoptysis. Chest
CT reveals a cavitary lesion with a "halo sign." Which opportunistic systemic fungal
infection is most likely present?
A. Sporotrichosis
B. Histoplasmosis
C. Aspergillosis [CORRECT]
D. Blastomycosis
Correct Answer: C
Rationale: Correct because the halo sign on CT and cavitary lung disease in an
immunocompromised patient are classic for invasive aspergillosis, an opportunistic
systemic fungal infection. This matches NUR 521 Exam 4 content on opportunistic
infections in immunocompromised hosts.
Q2: Which of the following fungal infections is classified as NON-opportunistic and
typically affects immunocompetent individuals?
A. Candidiasis
B. Cryptococcosis
C. Mucormycosis
D. Blastomycosis [CORRECT]
Correct Answer: D
Rationale: Correct because blastomycosis is a non-opportunistic systemic fungal
infection that typically affects healthy individuals, unlike candidiasis, cryptococcosis,
and mucormycosis which occur primarily in immunocompromised patients.
,Q3: A patient with neutropenia and persistent fever despite broad-spectrum antibiotics
develops disseminated fungal infection. Which drug is the drug of choice (DOC) for
most life-threatening systemic fungal infections due to its broad-spectrum activity?
A. Fluconazole
B. Itraconazole
C. Amphotericin B [CORRECT]
D. Nystatin
Correct Answer: C
Rationale: Correct because Amphotericin B remains the drug of choice for most
systemic fungal infections due to its broad-spectrum antifungal activity, despite its
significant toxicity profile including nephrotoxicity and infusion-related reactions.
Q4: Which azole antifungal carries a black box warning for negative inotropic effects
and is contraindicated in patients with heart failure?
A. Fluconazole
B. Voriconazole
C. Itraconazole [CORRECT]
D. Ketoconazole
Correct Answer: C
Rationale: Correct because Itraconazole has an FDA black box warning for negative
inotropic effects and should never be used in patients with heart failure, making it
contraindicated for superficial or systemic fungal infections in this population.
Q5: Which antifungal agent is primarily used to treat superficial fungal infections such
as candidiasis and cryptococcal meningitis, and is characterized by excellent oral
bioavailability?
A. Amphotericin B
B. Itraconazole
C. Fluconazole [CORRECT]
D. Griseofulvin
Correct Answer: C
Rationale: Correct because Fluconazole is well-tolerated, has excellent oral
bioavailability, and is the preferred agent for superficial candidiasis and cryptococcal
meningitis due to its good CNS penetration.
,Q6: Which organism is responsible for the majority of superficial fungal infections
involving mucosal surfaces, skin, and nails?
A. Aspergillus fumigatus
B. Cryptococcus neoformans
C. Candida albicans [CORRECT]
D. Mucor species
Correct Answer: C
Rationale: Correct because Candida albicans is the most common cause of superficial
fungal infections, particularly affecting mucosal surfaces, skin, and nails in both
immunocompetent and immunocompromised hosts.
Q7: The azole antifungals (itraconazole, fluconazole) exert their therapeutic effect by
inhibiting the synthesis of which critical fungal cell membrane component?
A. Chitin
B. Beta-glucan
C. Ergosterol [CORRECT]
D. Mannoprotein
Correct Answer: C
Rationale: Correct because the mechanism of action of azole antifungals is inhibition of
ergosterol synthesis, which disrupts fungal cell membrane integrity and prevents fungal
growth and survival.
Q8: A patient receiving Amphotericin B develops rising serum creatinine, hypokalemia,
and chills during infusion. Which adverse effect profile limits the use of this agent to
life-threatening infections?
A. Hepatotoxicity and ototoxicity
B. Nephrotoxicity and infusion-related reactions [CORRECT]
C. Pulmonary fibrosis and thyroid dysfunction
D. Myopathy and rhabdomyolysis
Correct Answer: B
Rationale: Correct because Amphotericin B is associated with significant nephrotoxicity
and infusion-related reactions including fever, chills, and rigors, which limit its use to
severe, life-threatening fungal infections.
Q9: Which antifungal agent is the preferred treatment for non-opportunistic systemic
infections such as histoplasmosis and blastomycosis?
, A. Amphotericin B
B. Fluconazole
C. Itraconazole [CORRECT]
D. Nystatin
Correct Answer: C
Rationale: Correct because Itraconazole is the preferred agent for non-opportunistic
systemic fungal infections including histoplasmosis and blastomycosis, while
Amphotericin B is reserved for severe or refractory cases.
Q10: A premature infant develops oral thrush. Which antifungal is preferred due to its
safety, localized action, and lack of systemic absorption?
A. Fluconazole
B. Itraconazole
C. Nystatin [CORRECT]
D. Amphotericin B
Correct Answer: C
Rationale: Correct because Nystatin is not systemically absorbed, has a localized effect
against Candida species, and is the preferred agent for oral candidiasis in premature
and full-term infants due to its safety profile.
Q11: Which of the following is an opportunistic systemic fungal infection that occurs
primarily in immunocompromised patients?
A. Sporotrichosis
B. Histoplasmosis
C. Cryptococcosis [CORRECT]
D. Blastomycosis
Correct Answer: C
Rationale: Correct because cryptococcosis is an opportunistic systemic fungal infection
that occurs primarily in immunocompromised patients, particularly those with
HIV/AIDS, unlike sporotrichosis, histoplasmosis, and blastomycosis which can affect
immunocompetent individuals.
Q12: A patient with hematologic malignancy develops rhinocerebral infection with
tissue necrosis. Which opportunistic fungal infection is most likely?
A. Aspergillosis
