Answer to Question 1

D
Feedback:
Secondary actions are those actions that occur as a result of taking a medication but do not fall under the category of therapeutic action and are often negative. This patient is experiencing a secondary action of erythromycin. Primary actions would be extensions of therapeutic action. Hypersensitivity reaction would be an excessive response to either the primary or secondary effects of a drug. An allergic reaction would be an immune response to the drug.

Answer to Question 2

C
Feedback:
Mebendazole and pyrantel, which are not absorbed systemically, may cause abdominal discomfort, diarrhea, or pain, but have very few other effects and are well-tolerated. Therefore options A, B, and D are incorrect.
