Correct Answer is A

Explanation

Choice A rationale:

An irregular pulse could indicate that myocarditis is affecting the heart’s electrical system, leading to an irregular heartbeat or arrhythmia. This could potentially affect the action of digoxin, a medication used to treat heart conditions, and therefore should be communicated to the healthcare provider.

Choice B rationale:

Leukocytosis, or a high white blood cell count, can be a sign of infection or inflammation, including myocarditis. However, it is not as specific as an irregular pulse in indicating a potential issue with the administration of digoxin.

Choice C rationale:

Generalized myalgia, or muscle pain, can be a symptom of myocarditis. However, it is not as directly related to the action of digoxin as an irregular pulse.

Choice D rationale:

Fatigue can be a symptom of myocarditis. However, it is not as directly related to the action of digoxin as an irregular pulse.

So, the correct answer is A, after analyzing all choices.

A. "Do you have a history of a heart attack?". B. "Have you had any recent immunizations?". C. "Do you have a family history of endocarditis?". D. "Have you had dental work done recently?".

Correct Answer is D

Explanation

Choice A rationale:

While a history of heart attack indicates a general risk for heart disease, it is not specifically associated with an increased risk for infective endocarditis.

Choice B rationale:

Immunizations do not typically increase the risk for infective endocarditis.

Choice C rationale:

Family history of endocarditis does not necessarily increase the risk for infective endocarditis.

Choice D rationale:

Dental work can introduce bacteria into the bloodstream, which can lead to infective endocarditis, especially in individuals with prosthetic heart valves.

So, the correct answer is D, after analyzing all choices.
