Nursing Elites

1. All of the following are electrolytes except:

• A. chloride
• B. potassium
• C. sodium
• D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.

2. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

• A. reducing cholesterol synthesis
• B. suppressing inflammation
• C. reducing blood clotting
• D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

3. Which food is a reliable source of B12 for a pregnant vegan client?

• A. Soybeans
• B. Algae
• C. Fortified soy milk
• D. Sea vegetables

Correct answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.

4. A nurse is developing an education program for a community group about dietary intake of vitamins and minerals in the diet. The nurse should include which of the following foods as sources of vitamin C? (Select the food that does not apply.)

• A. Green pepper
• B. Orange
• C. Cabbage
• D. Milk

Correct answer: D

Rationale: The correct answer is E: Milk. Milk is not a significant source of vitamin C. Choices A, B, C, and D are all good sources of vitamin C. Green pepper, orange, cabbage, and strawberries contain vitamin C and can be included in the diet to meet the body's need for this essential vitamin. Milk, on the other hand, is not known for its vitamin C content, so it does not apply as a source of this particular vitamin.

5. Which client is most likely to need regular injections of vitamin B12?

• A. The client with malabsorption syndrome.
• B. The client following a vegan eating pattern.
• C. The client whose stomach does not produce intrinsic factors.
• D. The client with alcoholism.

Correct answer: C

Rationale: The correct answer is C. The client whose stomach does not produce intrinsic factors is most likely to need regular injections of vitamin B12. Intrinsic factor is essential for the absorption of vitamin B12. Without intrinsic factor, the client cannot absorb vitamin B12 from food, necessitating the need for regular injections. Choices A, B, and D do not directly impact the production of intrinsic factors in the stomach, so they are less likely to result in the need for vitamin B12 injections.
