Answer to Question 1

ANS: D
Voriconazole can interact with many drugs. It should not be combined with drugs that are powerful P450 inhibitors, including phenobarbital, because these can reduce the levels of voriconazole. Administering the voriconazole IV will not increase the serum level. It is not correct to reduce the dose of either drug.

Answer to Question 2

ANS: B
Reduced visual acuity, increased brightness, altered color perception, and photophobia are reversible 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.
