1. A nurse is discussing macronutrients with a client. Which of the
following is the primary function of carbohydrates in the body?
A. Tissue repair and growth
B. Main source of energy
C. Insulation and protection of organs
D. Regulation of fluid balance
Answer: B. Carbohydrates serve as the body's primary energy source,
providing approximately 4 kcal per gram. Proteins primarily handle
tissue repair, while lipids are key for insulation.
2. A client asks how many calories per gram are provided by fat. The
nurse correctly responds:
A. 4 kcal/g
B. 7 kcal/g
C. 9 kcal/g
D. 12 kcal/g
,2|Page
Answer: C. Lipids provide 9 kcal per gram, making them the most
energy-dense macronutrient. Carbohydrates and proteins each provide
4 kcal/g, and alcohol provides 7 kcal/g.
3. A nurse is teaching about protein complementation. Which food
combination best demonstrates this principle?
A. Oatmeal with milk
B. Rice and beans
C. Pasta with cheese
D. Yogurt with granola
Answer: B. Rice and beans combine legumes and grains to provide all
essential amino acids, making a complete protein. The other pairings

4. Which of the following vitamins is water-soluble?
A. Vitamin A
B. Vitamin D
C. Vitamin C
D. Vitamin E
Answer: C. Vitamin C and the B-complex vitamins are water-soluble,

food choice indicates the teaching has been effective?
A. Cheese omelet
B. Spinach salad with lemon vinaigrette
C. Yogurt with berries
