The client asks how the body gets rid of cholesterol. Which response by the nurse is the most appropriate?
1. Cholesterol is secreted as HDL.
2. Cholesterol is secreted through the kidneys.
3. Cholesterol is secreted in bile.
4. Cholesterol is secreted in feces.
Correct Answer: 3
Rationale 1: As HDL is incorrect because high-density lipoprotein (HDL) picks up cholesterol in the blood and other tissues and returns it to the liver where it is used to make bile. Bile is essential for the digestion of lipids. The cholesterol component of bile is then excreted in the feces, though some may be reabsorbed back into the circulation. Excretion via bile is the only route the body uses to remove cholesterol.
Rationale 2: Through the kidneys is incorrect because the liver is the organ of excretion.
Rationale 3: High-density lipoprotein (HDL) picks up cholesterol in the blood and other tissues and returns it to the liver where it is used to make bile. Bile is essential for the digestion of lipids. The cholesterol component of bile is then excreted in the feces, though some may be reabsorbed back into the circulation. Excretion via bile is the only route the body uses to remove cholesterol.
Rationale 4: In feces is incorrect because high-density lipoprotein (HDL) picks up cholesterol in the blood and other tissues and returns it to the liver where it is used to make bile. Bile is essential for the digestion of lipids. The cholesterol component of bile is then excreted in the feces, though some may be reabsorbed back into the circulation.
