Question 5

Which equation correctly represents the calculation of total cholesterol?

Accepted Answer

$$	ext{Total Cholesterol} = 	ext{HDL} + 	ext{LDL} + (	ext{Triglycerides} / 5)$$

Question 6

Which of the following statements about LDL is correct?

Question 7

A patient has the following lipid profile: LDL = 160 mg/dL, HDL = 30 mg/dL, Total Cholesterol = 220 mg/dL. According to the cholesterol classification table, what is the patient's CVD risk?

Accepted Answer

High risk

Question 8

Which of the following best describes the role of VLDL in lipid transport?

VLDL delivers triglycerides produced by the liver to tissues.

Question 9

Which of the following lifestyle changes would NOT reduce the risk of cardiovascular disease?

Accepted Answer

Consuming more saturated fats

Question 10

Which pie chart composition best represents HDL?

Accepted Answer

A pie chart with the largest portion as protein, followed by phospholipids, cholesterol, and a small amount of triglycerides

Question 11

Which of the following statements about the relationship between lipoproteins and CVD is TRUE?

Accepted Answer

Increased LDL levels are associated with increased CVD risk.

Question 12

Which of the following best explains how atherosclerosis develops?

Accepted Answer

Over time, LDLs cause plaque buildup on blood vessel walls, reducing the width of the vessel.

Their risk for CVD increases

Question 15

Which of the following best describes the process by which HDL reduces cardiovascular disease risk?

HDL transports cholesterol from tissues to the liver for excretion

Question 16

Which of the following is a correct match between a blood lipid and its primary function?

Accepted Answer

Chylomicron – delivers dietary lipids from intestine to body

Question 17

Which of the following is a plausible reason why scientists believe there is a link between lipoprotein levels and heart disease risk?

Accepted Answer

High LDL levels are associated with increased plaque formation in arteries

Question 18
