Nursing Elites

1. A nurse is providing MyPlate education to a client newly diagnosed with diabetes mellitus. Which plate chosen by the client indicates the teaching was effective, according to the MyPlate guidelines?

• A. 1/2 of the plate is filled with carbohydrate foods, 1/4 filled with protein foods, and 1/4 filled with fruits and vegetables
• B. 1/2 of the plate is filled with protein foods, 1/4 filled with carbohydrates, and 1/4 filled with non-starchy vegetables
• C. 1/2 of the plate is filled with carbohydrates, 1/4 filled with protein foods, and 1/4 filled with non-starchy vegetables
• D. 1/2 of the plate is filled with non-starchy vegetables, 1/4 filled with protein foods, and 1/4 filled with carbohydrate foods

Correct answer: D

Rationale: The correct answer is D. This option reflects the MyPlate guidelines for managing diabetes effectively. In diabetes management, it is essential to focus on non-starchy vegetables, appropriate protein portions, and controlled carbohydrate intake. Option A places too much emphasis on carbohydrates, which may not be suitable for diabetes. Option B swaps the proportions of protein and carbohydrates, which is not in line with the recommended distribution. Option C places too much emphasis on carbohydrates and lacks the emphasis on non-starchy vegetables, making it less suitable for diabetes management.

2. A vegan patient might be at risk for deficiency in which of the following nutrients?

• A. Vitamin B12
• B. Vitamin C
• C. Carbohydrates
• D. Fiber

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.

3. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

4. Furosemide (Lasix) is a drug used to _____.

• A. activate vitamin D
• B. stimulate appetite
• C. lower cholesterol
• D. mobilize fluids

Correct answer: D

Rationale: Furosemide is a diuretic that helps mobilize fluids by increasing urine output, often used to treat conditions like edema and heart failure.

5. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?

• A. 1 cup grapes
• B. 1 cup shredded lettuce
• C. 1 cup cooked tomatoes
• D. 1 cup apple slices

Correct answer: C

Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.
