While reading the history, the nurse notices that the patient has stenosis of a heart valve.
How does the nurse interpret this finding? The valve:.

Permits blood to flow backward.

Fails to shut completely.

Is constricted and narrowed.

Regurgitates and causes insufficiency.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

"Permits blood to flow backward" is more characteristic of valvular regurgitation rather than stenosis. This choice is not accurate in the context of valvular stenosis.

Choice B rationale:

"Fails to shut completely" is a description of valvular regurgitation, not stenosis. This is not the correct choice.

Choice C rationale:

Stenosis of a heart valve means that the valve is constricted and narrowed, limiting the flow of blood through it. This choice is accurate and describes valvular stenosis correctly.

Choice D rationale:

"Regurgitates and causes insufficiency" is a description of valvular regurgitation, not stenosis. This choice is not appropriate in this context.

Correct Answer is C

Explanation

Choice A rationale:

Remodeling of arterial luminal walls is not a direct consequence of insulin resistance. Insulin resistance primarily affects glucose metabolism and can lead to hypertension through the activation of the renin-angiotensin-aldosterone system.

Choice B rationale:

Amino acid homocysteine is associated with cardiovascular disease, but it is not the primary mediator of insulin resistance or hypertension.

Choice C rationale:

Insulin resistance is associated with overactivity of the sympathetic nervous system and activation of the renin-angiotensin-aldosterone system. The renin-angiotensin-aldosterone system plays a significant role in regulating blood pressure, and its overactivity can contribute to hypertension.

Choice D rationale:

Increased afterload effect is a consequence of hypertension rather than a direct association with insulin resistance. Insulin resistance can lead to hypertension through various mechanisms, including sympathetic nervous system activation and renin-angiotensin-aldosterone system activation.

A. Subendocardial. B. Transmural. C. Cardial. D. Transient.

Correct Answer is B

Explanation

Choice A rationale:

Subendocardial MI typically involves the inner layer of the heart muscle and may not result in marked ST segment elevation. This is not the best choice.

Choice B rationale:

Transmural MI, also known as a full-thickness or ST-elevation myocardial infarction (STEMI), is characterized by marked ST segment elevation on the ECG. This is the correct choice because it accurately describes the scenario in the question.

Choice C rationale:

"Cardial" is not a recognized term in the context of myocardial infarctions. This choice is not appropriate.

Choice D rationale:

"Transient" does not describe the type of MI but rather suggests a temporary or reversible condition. It is not the best choice.
