Nursing Elites

1. Which of the following nutrients deficiency may lead to a diabetes-like condition?

• A. chromium
• B. iron
• C. molybdenum
• D. selenium

Correct answer: A

Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.

2. A nurse is teaching a client about iron-rich foods. Which food is the best source of heme iron?

• A. Spinach
• B. Lentils
• C. Beef liver
• D. Tofu

Correct answer: C

Rationale: Heme iron, found in animal products like beef liver, is more easily absorbed than non-heme iron from plant sources.

3. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

4. Select all that apply. Which nutrients are needed by the body to make hemoglobin?

• A. Iron
• B. Vitamin B12
• C. Niacin
• D. Folate

Correct answer: A

Rationale: The correct answer is A: Iron. Iron is an essential nutrient needed by the body to make hemoglobin, the protein in red blood cells that carries oxygen. While other nutrients like vitamin B12, niacin, and folate are important for various bodily functions, they are not directly involved in the production of hemoglobin. Vitamin B12 is essential for nerve function and DNA synthesis, niacin is important for metabolism, and folate is crucial for cell division and DNA synthesis. Therefore, only iron is specifically required for hemoglobin production.

5. A healthcare provider is teaching a client who has constipation about a high-fiber diet. Which of the following foods should be included as sources of fiber? (Select one that does not apply.)

• A. Whole wheat bread
• B. Kidney beans
• C. Refined cereals
• D. Blackberries

Correct answer: C

Rationale: Refined cereals are not a good source of fiber as they have been processed and stripped off most of their fiber content. Whole wheat bread, kidney beans, and blackberries are excellent sources of fiber. Whole wheat bread is made from whole grains, which are high in fiber. Kidney beans are rich in fiber and can help alleviate constipation. Blackberries are a good source of fiber and can aid in promoting bowel regularity.
