1. Almost all (99%) of the calcium in the body is used for?

• A. regulating the transmission of nerve impulses
• B. providing energy for cells
• C. providing rigidity for the bones
• D. regulating muscle contraction

Correct answer: C

Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.

2. Which food is recommended for someone with lactose intolerance?

• A. Skim milk
• B. Cheese
• C. Lactose-free yogurt
• D. Whole milk

3. Mr. Bruno asks what the “normal” allowable salt intake is. Your best response to Mr. Bruno is:

• A. 1 tsp of salt/day with iodine and sprinkle of MSG
• B. 5 gms per day or 1 tsp of table salt/day
• C. 1 tbsp of salt/day with some patis and toyo
• D. 1 tsp of salt/day but no patis and toyo

4. Which food should the nurse recommend for a client deficient in vitamin A?

• A. Orange slices
• B. Steamed carrots
• C. Apple sauce
• D. Baked potato

Correct answer: B

Rationale: The correct answer is B, steamed carrots, as they are high in vitamin A. Carrots are rich in beta-carotene, a precursor to vitamin A, which is essential for good vision, a healthy immune system, and cell growth. Oranges (choice A) are a good source of vitamin C but not vitamin A. Apple sauce (choice C) and baked potato (choice D) do not provide significant amounts of vitamin A compared to steamed carrots, making them less suitable recommendations for a client deficient in this specific nutrient.

• B. 30 minutes
• C. 1 hour
• D. 5 minutes

Correct answer: B
