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.

Correct Answer is A

Explanation

Choice A rationale:

A fasting triglyceride level of 167 mg/dL is above the desirable level of less than 150 mg/dL, indicating a higher risk for CAD34.

Choice B rationale:

An HDL level of 96 mg/dL is considered good and is protective against CAD34.

Choice C rationale:

An LDL level of 104 mg/dL is near optimal/above optimal, but it’s not high enough to be a priority risk factor for CAD34.

Choice D rationale:

Total serum cholesterol of 192 mg/dL is within the desirable range of less than 200 mg/dL34.

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

A. Obtain blood cultures x 3. B. Administer antibiotic therapy. C. Obtain an echocardiogram. D. Restrict dental hygiene. E. Perform strenuous exercise regimen twice daily.

Correct Answer is ["A","B","C"]

Explanation

Choice A rationale:

Obtaining blood cultures x 3 is anticipated for the client. This is because the adolescent’s symptoms such as fever, shortness of breath, and petechiae could indicate a bacterial infection, possibly endocarditis, which is a risk for individuals with a history of rheumatic fever and cardiac valve damage. Blood cultures would help identify the causative bacteria.

Choice B rationale:

Administering antibiotic therapy is anticipated for the client. The adolescent’s symptoms suggest a possible bacterial infection, which could have been introduced during the recent dental work. Antibiotics would help eliminate the bacteria and prevent further complications.

Choice C rationale:

Obtaining an echocardiogram is anticipated for the client. Given the adolescent’s history of rheumatic fever and cardiac valve damage, and current symptoms like shortness of breath and chest pain, an echocardiogram would help assess the condition of the heart valves and detect any abnormalities.

Choice D rationale:

Restricting dental hygiene is contraindicated for the client. Good oral hygiene is important, especially for individuals with a history of rheumatic fever and cardiac valve damage, as it helps prevent oral infections that could potentially spread to the heart.

Choice E rationale:

Performing a strenuous exercise regimen twice daily is contraindicated for the client. The adolescent is currently experiencing symptoms like shortness of breath and chest pain, which could be exacerbated by strenuous exercise. It’s important to avoid overexertion until the adolescent’s condition stabilizes.

So, the correct answer is, after analyzing all choices, Choices A, B, and C are anticipated for the client, while Choices D and E are contraindicated. .
