The nurse obtains a health history from an older adult with a prosthetic mitral valve who has symptoms of infective endocarditis (IE). Which question by the nurse helps identify a risk factor for IE?.

"Do you have a history of a heart attack?".

"Have you had any recent immunizations?".

"Do you have a family history of endocarditis?".

"Have you had dental work done recently?".

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

Choice A rationale:

The right upper-sternal border is not the best place to hear a murmur typical of mitral regurgitation.

Choice B rationale:

The left upper-sternal border is not the best place to hear a murmur typical of mitral regurgitation.

Choice C rationale:

The left lower-sternal border is not the best place to hear a murmur typical of mitral regurgitation.

Choice D rationale:

The apex of the heart is the best place to hear a murmur typical of mitral regurgitation. This is where the sound will be most audible.

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

A. Elevated troponin. B. Q Waves on ECG. C. Bilateral crackles. D. Hyperglycemia.

Correct Answer is A

Explanation

Choice A rationale:

Elevated troponin is a sign of heart damage, which could be caused by a heart attack or other stresses on the heart. This is a critical finding that needs immediate attention.

Choice B rationale:

Q waves on an ECG can indicate a previous heart attack or myocardial infarction. However, they can also be a normal variant, meaning they are a harmless variation in the electrical activity of the heart.

Choice C rationale:

Bilateral crackles in the lungs can indicate mucus or fluid in the base of the lungs, often associated with conditions like pneumonia, heart failure, or bronchitis.

Choice D rationale:

Hyperglycemia, or high blood glucose, can be a sign of diabetes. If untreated, it can lead to serious complications like ketoacidosis.

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