Answer to Question 1

C
Blurred vision or impaired mental acuity may result from the use of amantadine. Patients with a history of psychiatric illness may develop suicidal ideation, but this is not associated with blurred vision. It is not necessary to stop the medication. Patients with a history of seizures may have seizures with this drug, but this is not associated with blurred vision.

Answer to Question 2

B
Acyclovir is effective against herpes viruses including the varicella-zoster virus that causes shingles. Varicella vaccine is given to prevent shingles in older patients. Metronidazole is an antiprotozoal. Amantadine is given to treat influenza.
