Which of the following laboratory results will cause the nurse to suspect that a patient is prone to the development of the fatty streak in atherosclerosis?

High LDL.

Low LDL.

High HDL.

Low triglycerides.

Answer and Explanation

The Correct Answer is A

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.

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. Decreased heart rate. B. Increased renal excretion of sodium. C. Peripheral vasoconstriction. D. Decreased insulin resistance.

Correct Answer is C

Explanation

Choice A rationale:
Increased sympathetic nervous system (SNS) activity does not cause a decreased heart rate. In fact, increased SNS activity often leads to an increased heart rate as part of the "fight or flight" response, which is characterized by increased sympathetic activity.
Choice B rationale:
Increased sympathetic nervous system (SNS) activity does not result in increased renal excretion of sodium. Instead, it can lead to increased sodium reabsorption by the kidneys as part of the body's response to stress.
Choice D rationale:
Increased sympathetic nervous system (SNS) activity does not cause decreased insulin resistance. In fact, it can contribute to insulin resistance, as chronic stress and high levels of stress hormones like epinephrine and norepinephrine can lead to impaired insulin sensitivity.
