Answer to Question 1

B
Feedback:
Measuring serum drug levels is useful when drugs with a narrow margin of safety are given, because their therapeutic doses are close to their toxic doses. This is the case during lithium therapy. Serum levels are not commonly taken to monitor adherence to treatment. Blooddrug incompatibilities are not a relevant consideration.

Answer to Question 2

D
Feedback:
The administration of thyroid preparations should be done cautiously with nasal decongestants due to their increased effects. PPIs, anti-infectives, and anti-inflammatories do not have this effect.
