Which assessment Is most important for the nurse to obtain when a patient is being treated with a neuromuscular-blocking agent?

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.

The correct answer is choice A. “Monitor for ringing in your ears.”

Choice A rationale:

Erythromycin can cause ototoxicity, which may present as tinnitus (ringing in the ears). Monitoring for this side effect is important to prevent potential hearing damage.

Choice B rationale:

Yellowing of the skin is not a common side effect of erythromycin. This symptom is more associated with liver issues or jaundice, which is not typically linked to erythromycin use.

Choice C rationale:

Erythromycin is more likely to cause gastrointestinal side effects such as diarrhea rather than constipation. Increasing fiber intake is not necessary to prevent constipation when taking this medication.

Choice D rationale:

Grapefruit juice can interfere with the metabolism of many medications, including erythromycin, potentially leading to increased drug levels and risk of side effects. It is generally advised to avoid grapefruit juice while taking erythromycin.
