Question

A nurse is providing information about cardiovascular risk to a ct who has received a lipid panel report. The nurse should include that which of the following findings is within an expected reference range?

a) High-density lipoprotein (HDL) cholesterol of 30 mg/dL
b) Low-density lipoprotein (LDL) cholesterol of 150 mg/dL
c) Triglycerides level of 200 mg/dL
d) Total cholesterol of 250 mg/dL

Answer 1

A total cholesterol level of 250 mg/dL is considered high and not within the expected reference range. Low levels of HDL cholesterol and high levels of LDL cholesterol increase the risk of heart disease. Dietary modifications and increased physical activity can help lower total cholesterol and improve the LDL:HDL ratio.

Step-by-step explanation:

A total cholesterol level of 250 mg/dL is considered high and is not within the expected reference range. The desired range for total blood cholesterol is under 200 mg/dL to maintain good cardiovascular health. High levels of LDL cholesterol increase the risk of heart disease, while high levels of HDL cholesterol reduce the risk.

For individuals, an LDL level of less than 100 mg/dL is ideal. However, an LDL level above 160 mg/dL would be considered high and indicate an increased risk of heart attack. On the other hand, a low value of HDL cholesterol, below 40 mg/dL for men and 50 mg/dL for women, is a risk factor for developing heart disease.

In order to lower total cholesterol and improve the LDL:HDL ratio, dietary modifications and increased physical activity are recommended. Substituting unsaturated fat for saturated fat, as well as reducing the consumption of trans fatty acids, can help lower serum cholesterol and reduce the risk of heart disease.
