If a patient's history indicates that the cardiac valve disease is autosomal dominant, which diagnosis will the nurse observe written in the chart?

Mitral valve prolapse.

Pulmonary stenosis.

Tricuspid regurgitation.

Aortic stenosis.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Mitral valve prolapse is an autosomal dominant condition. If a patient's history indicates that cardiac valve disease is autosomal dominant, the nurse is likely to find a diagnosis of mitral valve prolapse in the patient's chart. Mitral valve prolapse is a condition where the mitral valve doesn't close properly, allowing blood to flow back into the left atrium.

Choice B rationale:

Pulmonary stenosis is not typically associated with autosomal dominant inheritance. It's more commonly associated with sporadic genetic mutations or other non-genetic factors.

Choice C rationale:

Tricuspid regurgitation is not usually an autosomal dominant condition. Like pulmonary stenosis, it's often caused by other factors rather than being directly related to genetic inheritance.

Choice D rationale:

Aortic stenosis is not typically an autosomal dominant condition. It's more commonly related to age-related degeneration or other non-genetic factors.

Correct Answer is C

Explanation

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.

A. High LDL. B. Low LDL. C. High HDL. D. Low triglycerides.

Correct Answer is A

Explanation

Choice A rationale:

High LDL (low-density lipoprotein) levels are a well-established risk factor for atherosclerosis. Elevated LDL cholesterol can lead to the deposition of cholesterol in the arterial walls, promoting the development of atherosclerotic plaques. Typically, an LDL level above 130 mg/dL is considered high.

Choice B rationale:

Low LDL levels are generally considered beneficial and are not associated with a higher risk of atherosclerosis. Lower LDL levels can be achieved through lifestyle modifications or medication and are often recommended for cardiovascular health.

Choice C rationale:

High HDL (high-density lipoprotein) levels are associated with a lower risk of atherosclerosis. HDL is considered "good" cholesterol because it helps remove excess cholesterol from the arteries. High HDL levels are typically desirable for cardiovascular health.

Choice D rationale:

Low triglyceride levels are not a primary risk factor for atherosclerosis. Elevated triglyceride levels can be associated with metabolic syndrome and other cardiovascular risk factors, but they are not as directly linked to atherosclerosis as high LDL levels.
