Answer to Question 1

B
Reduced visual acuity, increased brightness, altered color perception, and photophobia are re-versible visual disturbances that can occur in 30 of patients receiving voriconazole. These usually begin within 30 minutes of dosing and then diminish over the next 30 minutes. They are not precursors to other effects, such as hallucinations. They do not indicate CNS toxicity. They are reversible.

Answer to Question 2

D
Voriconazole has replaced amphotericin B as the drug of choice for treating invasive aspergillosis. Fluconazole, which is fungistatic, is not used to treat aspergillosis. Posaconazole is used for prophylaxis of aspergillosis in immunocompromised patients.
