The client asks which components of the lipid profile should be low. What is the most appropriate response by the nurse?

Total cholesterol levels do not give sufficient information

VLDL should be high

LDL should be low

HDL should be low

Answer and Explanation

The Correct Answer is C

C. Low-density lipoprotein (LDL) cholesterol is often referred to as "bad" cholesterol, and lower levels are associated with reduced risk of cardiovascular disease.

D. High-density lipoprotein (HDL) cholesterol is often referred to as "good" cholesterol, and higher levels are associated with reduced risk of cardiovascular disease.
