Section I: Macronutrients & Energy Balance
,Question 1
A nurse is teaching a client about macronutrients. Which of the
following statements by the client indicates an understanding
of the teaching?
A. “Fats provide 4 calories per gram.”
B. “Carbohydrates are the body’s primary energy source.”
C. “Protein should make up the majority of my caloric intake.”
D. “Vitamins are considered a macronutrient.”
Correct Answer: B
Rationale: Carbohydrates are the body's primary and most
efficient source of energy, providing 4 kcal/g and supplying
glucose for brain function and cellular metabolism. Fats
provide 9 kcal/g, while proteins provide 4 kcal/g —making
option A incorrect. Protein should provide approximately 10–
35% of daily caloric intake, not the majority, making option C
incorrect. Vitamins are micronutrients, needed in trace
amounts, making option D incorrect.
Clinical Judgment Skill: Evaluate Outcomes
Question 2
A client asks the nurse about increasing dietary fiber. The nurse
should explain that soluble fiber is particularly beneficial for
which of the following conditions?
A. Constipation
B. Hypercholesterolemia
, C. Dehydration
D. Iron-deficiency anemia
Correct Answer: B
Rationale: Soluble fiber (found in oats, barley, beans, apples)
binds with cholesterol in the digestive tract and helps excrete it,
thereby lowering LDL cholesterol levels. Insoluble fiber is
more beneficial for promoting bowel regularity and preventing
constipation, making option A incorrect. Dehydration (C) and
iron-deficiency anemia (D) are not directly addressed by soluble
fiber intake.

Question 3
A nurse is educating a client about complete and incomplete
proteins. Which of the following foods should the nurse identify
as a complete protein?
A. Lentils
B. Peanut butter
C. Soybeans
D. Whole-wheat bread
Correct Answer: C
Rationale: Complete proteins contain all nine essential
amino acids and are found in animal sources (meat, poultry,
fish, eggs, dairy) and soy products. Lentils (A), peanut butter
(B), and whole-wheat bread (D) are incomplete proteins
because they lack one or more essential amino acids.
