DOMAIN 1: FOUNDATIONS OF NUTRITION & MACRONUTRIENTS (15 QUESTIONS)
Question 1
Which nutrient provides the body with 4 kcal per gram and is the body's preferred energy
source?
A. Protein
B. Fat
C. Carbohydrate
D. Alcohol
CorreCt Answer: C ✓
rAtionAle: Carbohydrates provide 4 kcal/g and are the primary and preferred energy source
for the brain, red blood cells, and central nervous system. The brain alone requires
approximately 120-140 g of glucose per day.
Question 2
The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates is:
A. 10–35% of total calories
B. 20–35% of total calories
C. 45–65% of total calories
D. 25–35% of total calories
CorreCt Answer: C ✓
rAtionAle: The Institute of Medicine (IOM) recommends that 45–65% of total daily calories
come from carbohydrates for adults. This range ensures adequate energy intake while allowing
sufficient room for protein and fat.
Question 3
Which of the following is the most accurate definition of a complete protein?
, A. Contains all essential amino acids in adequate amounts
B. Contains only non-essential amino acids
C. Is found only in animal products
D. Provides 9 kcal per gram
CorreCt Answer: A ✓
rAtionAle: Complete proteins contain all nine essential amino acids in sufficient quantities to
support growth and maintenance. Examples include animal proteins, soy, and quinoa.
Incomplete proteins lack one or more essential amino acids.
Question 4
The primary function of dietary fiber is to:
A. Provide energy
B. Promote satiety and regulate bowel function
C. Serve as a structural component of cell membranes
D. Act as a precursor for vitamin D synthesis
CorreCt Answer: B ✓

Question 5
A nurse is calculating the calorie content of a snack containing 10 grams of carbohydrates, 5
grams of fat, and 4 grams of protein. What is the total kilocalorie count?
A. 101 kcal
B. 91 kcal
C. 115 kcal
D. 125 kcal
CorreCt Answer: A ✓
rAtionAle: Carbohydrates and proteins each provide 4 kcal/g, while fats provide 9 kcal/g.
Calculation: (10 g × 4) + (5 g × 9) + (4 g × 4) = 40 + 45 + 16 = 101 kcal.
Question 6
Which macronutrient is generally the body's preferred source of energy?
A. Carbohydrate
B. Protein
