Correct Answer is C

Explanation

Enteric-coated aspirin is designed to release slowly over time to protect the stomach lining from irritation. Crushing the medication would defeat this purpose and could cause stomach irritation or other side eﬀects.

A. Headache B. Constipation C. Bradycardia D. Hypertension

Correct Answer is B

Explanation

The correct answer is choice b. Constipation.

Choice A rationale:

While headaches can occur with some medications, they are not a common adverse effect of diphenhydramine. Diphenhydramine's typical side effects are more related to its anticholinergic properties.

Choice B rationale:

Diphenhydramine is an antihistamine with anticholinergic effects, which can lead to dry mouth, urinary retention, and constipation as common adverse effects.

Choice C rationale:

Diphenhydramine typically does not cause bradycardia. In some cases, it may cause tachycardia (increased heart rate) rather than a slower heart rate.

Choice D rationale:

Hypertension is not typically associated with diphenhydramine. In fact, it can sometimes cause hypotension (low blood pressure) rather than high blood pressure.
