A nurse is describing the pathophysiology of atherosclerosis.
Which information should the nurse include? The main white blood cell that plays a role in the development of the fatty streak in atherosclerosis is the:.

Mast cell.

Neutrophil.

Macrophage.

Lymphocyte.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Mast cells are involved in the inflammatory response but are not the primary white blood cells responsible for the development of fatty streaks in atherosclerosis. Mast cells release histamines and other inflammatory mediators.

Choice B rationale:

Neutrophils are primarily responsible for fighting bacterial infections and are not the primary cells involved in atherosclerosis. While inflammation is a component of atherosclerosis, neutrophils are not the main cells responsible for the development of fatty plaques.

Choice C rationale:

Macrophages play a central role in atherosclerosis. They are responsible for engulfing oxidized LDL cholesterol in arterial walls, which then contributes to plaque formation. Macrophages play a pivotal role in the inflammatory response within the arterial walls, leading to atherosclerosis.

Choice D rationale:

Lymphocytes are involved in the immune response, but they are not the primary cells responsible for the development of fatty streaks in atherosclerosis. Lymphocytes play a role in the adaptive immune system and are not as directly involved in the early stages of atherosclerosis as macrophages.

Correct Answer is A

Explanation

Choice A rationale:

Unstable plaque in the coronary arteries is a major risk factor for myocardial infarction (MI), also known as a heart attack. When the plaque ruptures or becomes unstable, it can lead to the formation of a blood clot, which can obstruct the blood flow to the heart muscle, causing myocardial infarction. The nurse should monitor for signs and symptoms of MI in this patient, such as chest pain, shortness of breath, and ECG changes, to provide prompt intervention and prevent further cardiac damage.

Choice B rationale:

Stable angina is not the most immediate complication associated with unstable plaque in the coronary arteries. While stable angina is related to reduced blood flow to the heart, it is typically triggered by exertion or stress and relieved with rest or medication. Unstable plaque is more likely to lead to myocardial infarction, which is a more critical condition.

Choice C rationale:

Eupnea refers to normal, unlabored breathing and is not a complication associated with unstable plaque in the coronary arteries. It is essential to monitor the patient for cardiac-related complications, such as myocardial infarction, which can be life-threatening.

Choice D rationale:

Orthostatic hypotension, a drop in blood pressure upon standing, is not a typical complication of unstable plaque in the coronary arteries. The primary concern with unstable plaque is the risk of myocardial infarction, as it can lead to acute and severe cardiac damage.

A. Leptin. B. Adiponectin. C. Homocysteine. D. C-reactive protein.

Correct Answer is A

Explanation

Choice A rationale:

Leptin is a hormone produced by adipose tissue, and it plays a key role in regulating appetite and body weight. In obesity, there is an excessive amount of adipose tissue, leading to an increase in leptin levels. However, despite the higher levels of leptin, obese individuals may become resistant to its effects, leading to a decrease in the body's ability to respond to leptin signals. This condition is known as leptin resistance. Therefore, it is important to understand that obesity can cause a decrease in the effectiveness of leptin, which is critical for appetite regulation and body weight control.

Choice B rationale:

Adiponectin is another hormone produced by adipose tissue, but it has the opposite effect of leptin. Adiponectin levels are typically lower in obese individuals. While it is associated with various metabolic benefits, including improved insulin sensitivity, it doesn't directly decrease due to obesity.

Choice C rationale:

Homocysteine is not directly related to obesity. Homocysteine is an amino acid that is involved in various metabolic processes, and elevated levels are more commonly associated with cardiovascular disease and other health conditions, but not obesity.

Choice D rationale:

C-reactive protein (CRP) is a marker of inflammation in the body. While obesity is associated with chronic inflammation, it doesn't directly cause a decrease in CRP levels. In fact, obesity is more likely to lead to increased CRP levels, indicating higher levels of inflammation in the body.
