While auscultating a patient's heart sounds, a nurse detects a fourth heart sound (S4). The nurse understands that this finding possibly indicates:.

Pericarditis.

Arterial obstruction or aneurysm.

Forceful atrial contraction to overcome ventricular resistance.

An infectious valvular disorder.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Pericarditis is an inflammation of the pericardium and would not directly cause an S4 heart sound.

Choice B rationale:

Arterial obstruction or aneurysm would cause changes in blood flow, but not specifically an S4 heart sound.

Choice C rationale:

An S4 heart sound is an extra sound that is heard late in diastole just before S1. It occurs due to resistance to blood flow in an enlarged ventricle, often due to forceful atrial contraction to overcome ventricular resistance.

Choice D rationale:

An infectious valvular disorder could cause a variety of heart sounds, but not specifically an S42.

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

Limiting salt and fluid intake is crucial for patients with restrictive cardiomyopathy to manage their condition.

Choice B rationale:

Avoiding aspirin or other anti-inflammatory drugs is not specifically related to the management of restrictive cardiomyopathy.

Choice C rationale:

Taking antibiotics before dental cleaning is a general recommendation for patients with certain heart conditions to prevent endocarditis, but it’s not specific to restrictive cardiomyopathy.

Restarting an exercise program should be done under medical supervision and depends on the patient’s overall health status.

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