Answer to Question 1

A
Feedback:
Asians in general need much smaller doses of beta-blockers because they metabolize and excrete beta-blockers slowly. They do not metabolize beta-blockers in the small intestine. They do not have diminished renal excretion of beta-blockers. They do not have a lower albumin level.

Answer to Question 2

D
Feedback:
It is important to avoid administering imipenemcilastatin and the other carbapenems to people with life-threatening allergic reactions to penicillin. Diabetes, slightly increased creatinine levels, and fluid overload do not necessarily contraindicate the use of imipenemcilastatin.
