Section 1: Foundations of Nutrition — Macronutrients (Q1–
Q40)
,Q1. Which nutrient provides the most energy per gram?
A) Carbohydrates
B) Protein
C) Fat
D) Water
Answer: C
Rationale: Fat provides 9 kcal per gram, while carbohydrates
and protein provide 4 kcal per gram. Water provides 0 kcal per
gram. Fats are the most concentrated source of energy in the
diet and serve as the body's primary energy storage form.
Q2. 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."
Answer: B
Rationale: Carbohydrates are the body's main source of energy,
providing 4 kcal/g. Fats provide 9 kcal/g, and proteins provide 4
kcal/g. Macronutrients (carbs, fats, protein) are needed in large
amounts, while micronutrients (vitamins, minerals) are needed
in trace amounts.
, Q3. Which of the following is a complex carbohydrate?
A) White bread
B) Brown rice
C) Chicken
D) Butter
Answer: B
Rationale: Brown rice is a complex carbohydrate that provides
more fiber and takes longer to digest compared to simple
carbohydrates. Whole grains, fruits, and vegetables provide
dietary fiber, which aids digestion and prevents constipation.
Q4. 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
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.
