1. With which of the following should fluoride supplements never be taken?
- A. Water
- B. Juice
- C. Milk
- D. Soda
Correct answer: C
Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.
2. 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.
3. Which physiologic role does vitamin C play in the body?
- A. Transcribing DNA to RNA
- B. Absorption and regulation of calcium
- C. Protects integrity of cellular membranes
- D. Catalyst for synthesis of blood-clotting factors
Correct answer: C
Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.
4. Macronutrients include each of the following except one. Which one is the exception?
- A. Fat
- B. Polyunsaturated fatty acids
- C. Carbohydrate
- D. Protein
Correct answer: D
Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.
5. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child's diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?
- A. Skim milk
- B. Bananas
- C. Tuna fish
- D. Cucumbers
Correct answer: C
Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.
