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
The Correct Answer is C
A. Total cholesterol levels alone do not provide sufficient information about the lipid profile; it is important to assess individual components such as LDL, HDL, and triglycerides.
B. Very low-density lipoprotein (VLDL) is associated with increased risk of cardiovascular disease when elevated, so it should not be high.
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.

B. Constricting veins and coronary arteries would exacerbate angina symptoms by reducing blood flow to the heart muscle.
