Verified Answers with Detailed EXPERT RATIONALE
• Study Tip: Work through each question independently before checking the
answer and EXPERT RATIONALE — this mirrors the real exam experience and
strengthens critical thinking for NGN-style questions.
• Document Features: 200 high-yield multiple-choice questions with 5 options
each (A–E), bolded correct answers, and detailed EXPERT RATIONALE covering all
core ATI Nutrition competency areas.
SECTION 1: MACRONUTRIENTS & ENERGY METABOLISM
1. A nurse is teaching a client about carbohydrate intake. Which statement
best describes the primary role of carbohydrates in the body?
A. To build and repair muscle tissue
B. To transport fat-soluble vitamins
C. To insulate and protect vital organs
D. To regulate fluid and electrolyte balance
E. To serve as the body's primary and preferred source of energy
Correct Answer: E. To serve as the body's primary and preferred source of
energy
, EXPERT RATIONALE: Carbohydrates are the body's main and most efficient fuel
source. Glucose, derived from carbohydrate digestion, is the preferred energy substrate
for the brain, red blood cells, and muscles during activity.
2. A nurse is counseling a client on daily caloric intake from carbohydrates.
According to the Acceptable Macronutrient Distribution Range (AMDR), what
percentage of total daily calories should come from carbohydrates?
A. 10–25%
B. 20–35%
C. 15–30%
D. 50–65%
E. 45–65%
Correct Answer: E. 45–65%
EXPERT RATIONALE: The AMDR for carbohydrates is 45–65% of total daily caloric
intake. This range supports energy needs while allowing flexibility for other
macronutrients.
3. A nurse is educating a client about dietary fiber. Which of the following
foods is the BEST source of soluble fiber?
A. Wheat bran
B. Celery
C. Whole wheat bread
D. Oats
E. Lettuce
Correct Answer: D. Oats
, EXPERT RATIONALE: Oats are a rich source of soluble fiber (beta-glucan), which
dissolves in water to form a gel-like substance. Soluble fiber helps lower LDL cholesterol
and stabilize blood glucose levels.
4. A client asks a nurse about the difference between simple and complex
carbohydrates. Which of the following is classified as a complex
carbohydrate?
A. Table sugar (sucrose)
B. Honey
C. Fruit juice
D. Brown rice
E. Candy bar
Correct Answer: D. Brown rice
EXPERT RATIONALE: Complex carbohydrates (polysaccharides) are made of long
chains of glucose molecules. Brown rice is a complex carbohydrate that provides
sustained energy and fiber, unlike simple sugars which cause rapid blood glucose spikes.
5. A nurse is reviewing a client's diet recall. The client consumes 2,000 calories
per day. How many grams of protein per day is recommended for a healthy
adult based on the AMDR?
A. 10–50 grams
B. 100–175 grams
C. 50–175 grams
D. 200–250 grams
E. 25–40 grams
Correct Answer: C. 50–175 grams
, EXPERT RATIONALE: The AMDR for protein is 10–35% of total caloric intake. For a
2,000-calorie diet: 10% = 200 kcal ÷ 4 = 50g; 35% = 700 kcal ÷ 4 = 175g. Therefore, 50–
175 grams per day is appropriate.
6. A nurse is teaching a client about complete proteins. Which of the following
foods is considered a complete protein source?
A. Kidney beans
B. Brown rice
C. Almonds
D. Eggs
E. Lentils
Correct Answer: D. Eggs
EXPERT RATIONALE: Complete proteins contain all nine essential amino acids in
adequate amounts. Animal-based foods such as eggs, meat, fish, and dairy are complete
proteins. Plant sources such as beans, lentils, and rice are typically incomplete proteins.
7. A nurse is counseling a vegetarian client on protein complementation.
Which meal combination provides all essential amino acids?
A. Fruit salad and orange juice
B. Steamed vegetables and olive oil
C. Rice and beans
D. Lettuce and tomato salad
E. Apple slices and peanut butter alone
Correct Answer: C. Rice and beans
