Nursing Elites

1. Which of the following statements is correct about MyPlate?

• A. Canned fruit can be considered part of the fruit group
• B. Soymilk is considered part of the dairy group
• C. Beans and peas are considered part of both the protein group and the vegetable group
• D. Cream cheese and butter are not part of the dairy group

Correct answer: C

Rationale: According to the MyPlate guide, beans and peas are classified as part of both the protein and vegetable groups due to their high protein content and the nutrients they share with vegetables. This makes Choice C correct. Choice A is incorrect as canned fruit can be part of the fruit group if it's canned in water or 100% fruit juice. Soymilk is considered part of the dairy group, making Choice B incorrect. While cream cheese and butter are dairy products, they are not part of the dairy group on MyPlate because they contain little to no calcium, making Choice D incorrect.

2. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

• A. Spinach
• B. Cantaloupe
• C. Chicken
• D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

3. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

4. A nurse is assessing a client who reports muscle spasms in his calves and tingling in his hands. The client indicates consuming a low intake of milk products and green leafy vegetables. The nurse should identify that the client's findings indicate a deficiency in which of the following sources of nutrition?

• A. Iron
• B. Omega-3 fatty acids
• C. Vitamin C
• D. Calcium

Correct answer: D

Rationale: The correct answer is D, Calcium. Muscle spasms and tingling suggest a calcium deficiency, which is commonly associated with a low intake of milk products and green leafy vegetables. Iron (choice A) deficiency typically presents with fatigue and weakness, not muscle spasms and tingling. Omega-3 fatty acids (choice B) are essential for brain function and heart health, but their deficiency does not manifest as muscle spasms and tingling. Vitamin C (choice C) deficiency leads to scurvy with symptoms like bleeding gums and bruising, not muscle spasms and tingling.

5. Increasing the variety of foods often prevents nutrient excesses and toxicities. A dietary change to eliminate or increase intake of one specific food or nutrient usually alters the intake of other nutrients.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: D

Rationale: The first statement is false because increasing the variety of foods actually helps prevent nutrient excesses and toxicities. The second statement is true because making a dietary change to eliminate or increase the intake of a specific food or nutrient often leads to alterations in the intake of other nutrients. Choice A is incorrect because the first statement is false. Choice B is incorrect because the second statement is true. Choice C is incorrect because the first statement is false, even though the second statement is true.
