Answer to Question 1

ANS: B
Patients with a creatinine clearance of 30 to 49 mL/min should take 0.25 mg of entecavir per day. It is not correct to continue the same dose or to increase the dose. Dialysis is not indicated.

Answer to Question 2

ANS: B
Oseltamivir is most effective when begun within 2 days after symptom onset. When started within 12 hours of symptom onset, it may decrease duration of symptoms by 2 to 3 days. The drugs reduces both symptom severity and symptom duration when used in a timely fashion. It does not rapidly alleviate symptoms.
