Answer to Question 1

C
Chest pain is never considered normal. Chest pain should be reported to the prescriber any time a patient experiences it because this is one symptom of many serious cardiac problems.

Answer to Question 2

C
With a half-life of 2 hours, the amount of drug remaining in the blood decreases by 50 every 2 hours. So, when 400 mg are given at noon, by 2:00 p.m. 200 mg remain; by 4:00 p.m., 100 mg remain; by 6:00 p.m., 50 mg remain; by 8:00 p.m., 25 mg remain; by 10:00 p.m., 12.5 mg remain, and by midnight, 6.25 mg remain.
