Answer to Question 1

ANS: D
The lowest amount of a medication in the blood is the trough. The peak is the highest amount of medication in the blood. Serum level identifies the amount of medication present. Therapeutic levels identify the range in which a medication is effective.

Answer to Question 2

ANS: B
An obese individual would require a larger dose of a drug to attain a therapeutic response. An individual with kidney failure would require less medication because of decreased excretory ability. Individuals with decreased metabolic rate would metabolize drugs more slowly and require smaller doses or less frequent administration. Individuals with decreased circulation would require less medication.
