SECTION 1 — Principles of Nutrition and Nutritional Assessment
(Chapters 1–3)
Q1 – Q50 | Nutrients, Digestion, Absorption, Metabolism, Energy Balance, Anthropometric, Biochemical,
Clinical, and Dietary Assessment
Q1: A nurse is teaching a community class on the basic principles of nutrition. Which statement by
a participant indicates a correct understanding of a nutrient that provides energy (kilocalories) per
gram?
A. Vitamins provide 4 kcal/g and are the primary energy source.
B. Carbohydrates provide 4 kcal/g and are the body's preferred energy source. [CORRECT]
C. Water provides 7 kcal/g and is essential for energy metabolism.
D. Minerals provide 9 kcal/g and are stored as glycogen.
Correct Answer: B
Rationale: Carbohydrates and proteins each yield 4 kcal/g, lipids yield 9 kcal/g, and alcohol yields 7 kcal/g. Vitamins,
minerals, and water yield no kilocalories; they are micronutrients and essential for metabolism but do not themselves provide
energy. ATI testing strategy: memorize the energy-yield values (4-4-9-7) and recall that water and micronutrients are
non-energy-yielding. Choice A is wrong because vitamins are non-energy nutrients; C is wrong because water yields 0 kcal;
D is wrong because minerals yield 0 kcal and glycogen is a carbohydrate, not a mineral.
Q2: A nurse is calculating the energy needs of an adult female client who weighs 60 kg using the
Harris-Benedict equation. The client's estimated basal energy expenditure (BEE) is approximately
1300 kcal/day. Which factor would most significantly increase this client's actual daily energy
requirement above BEE?
A. Sleeping 8 hours per night
B. Being postoperative day 1 after elective surgery
C. Having a fever of 38.5°C (101.3°F) [CORRECT]
D. Being on a mechanical soft diet
Correct Answer: C
Rationale: BEE (basal energy expenditure) represents energy needs at complete rest; actual daily requirement is BEE
multiplied by activity and stress factors. Fever increases metabolic rate by approximately 7% per 0.5°C above normal, and
38.5°C represents a 1.4°C elevation, markedly raising energy demand. Choice A would keep demand near BEE; B (postop
day 1) increases needs less than ongoing fever and is often associated with a brief stress response; D (diet texture) does not
change energy requirement. ATI testing strategy: identify stress and activity factors that modify BEE; fever, burns, sepsis,
and trauma are major caloric stressors.
Q3: A nurse is teaching a client about the Digestion, Absorption, and Metabolism of
carbohydrates. The nurse correctly identifies that the primary site of carbohydrate digestion is the:
A. Mouth, where salivary amylase begins starch breakdown. [CORRECT]
B. Stomach, where hydrochloric acid breaks down sucrose.
C. Large intestine, where fiber is fermented into glucose.
D. Liver, where bile emulsifies complex carbohydrates.
Correct Answer: A
Page 3
, ATI RN Nutrition Edition 9.0 — Complete Test Bank (300 Questions) A+ Graded | 2026 Curriculum Aligned
Rationale: Carbohydrate digestion begins in the mouth, where salivary amylase (ptyalin) starts breaking starch into smaller
polysaccharides and maltose. Digestion pauses in the stomach (acid inactivates amylase) and resumes in the small intestine
with pancreatic amylase and intestinal brush-border enzymes (maltase, sucrase, lactase), producing monosaccharides
(glucose, fructose, galactose) for absorption in the small intestine. Choice B is wrong—HCl denatures protein, not
carbohydrates; C is wrong—fiber is fermented into short-chain fatty acids, not glucose; D is wrong—bile emulsifies fats, not
carbohydrates. ATI strategy: map each macronutrient to its digestion site (carbs-mouth, fats-small intestine with bile,
proteins-stomach).
Q4: A nurse is assessing a client's nutritional status using anthropometric measurements. Which
measurement is most useful for evaluating long-term protein-calorie status and is considered an
indicator of chronic malnutrition in adults?
A. Weight change over the past 48 hours
B. Mid-upper arm circumference (MAC) [CORRECT]
C. Body mass index (BMI) calculated from current weight
D. Triceps skinfold (TSF) thickness
Correct Answer: B
Rationale: Mid-upper arm circumference (MAC or MUAC) reflects muscle and fat stores and is a sensitive indicator of
long-term (chronic) protein-calorie malnutrition, especially in adults and older adults. Weight change over 48 hours reflects
fluid shifts, not nutritional status. BMI reflects current weight for height but does not distinguish acute from chronic changes.
Triceps skinfold measures fat stores only, not lean mass. ATI testing strategy: associate MAC/MUAC with chronic
malnutrition; weight changes (<7 days = acute; >7 days = chronic), skinfolds = fat stores, and MAC = muscle + fat.
Q5: A nurse is calculating a client's body mass index (BMI). The client weighs 175 lb and is 5 ft 9 in
tall. Which BMI category does this client fall into according to the Centers for Disease Control and
Prevention (CDC)?
A. Underweight (BMI 18.4 or less)
B. Healthy weight (BMI 18.5–24.9)
C. Overweight (BMI 25.0–29.9) [CORRECT]
D. Obese Class I (BMI 30.0–34.9)
Correct Answer: C
Rationale: BMI = weight (kg) / height (m²) or [weight (lb) / height (in²)] × 703. Converting: 175 lb × 703 = 123,025; height
5 ft 9 in = 69 in, 69² = 4761; 123, = 25.8, which falls into the overweight category (25.0–29.9). Choice A (<18.5) is
underweight; B (18.5–24.9) is healthy; D (30–34.9) is Class I obesity. ATI testing strategy: memorize CDC BMI cutoffs
(underweight <18.5, healthy 18.5–24.9, overweight 25–29.9, Class I 30–34.9, Class II 35–39.9, Class III ≥40) and be able to
calculate BMI from either metric or imperial data.
Q6: A nurse is reviewing laboratory values for a client undergoing nutritional assessment. Which
laboratory value reflects short-term (recent) nutritional status and is most useful for monitoring
response to nutritional support within 1–2 weeks?
A. Albumin
B. Prealbumin [CORRECT]
C. Total lymphocyte count
D. Hemoglobin
Correct Answer: B
Rationale: Prealbumin (transthyretin) has a half-life of approximately 2–3 days, making it the most sensitive indicator of
recent protein status and a good marker for monitoring response to nutritional support within 1–2 weeks. Albumin has a

A. Sleeping 8 hours per night
B. Being postoperative day 1 after elective surgery
C. Having a fever of 38.5°C (101.3°F) [CORRECT]

Q4: A nurse is assessing a client's nutritional status using anthropometric measurements. Which
measurement is most useful for evaluating long-term protein-calorie status and is considered an
indicator of chronic malnutrition in adults?
A. Weight change over the past 48 hours
B. Mid-upper arm circumference (MAC) [CORRECT]
C. Body mass index (BMI) calculated from current weight
D. Triceps skinfold (TSF) thickness
Correct Answer: B
Rationale: Mid-upper arm circumference (MAC or MUAC) reflects muscle and fat stores and is a sensitive indicator of
long-term (chronic) protein-calorie malnutrition, especially in adults and older adults. Weight change over 48 hours reflects
fluid shifts, not nutritional status. BMI reflects current weight for height but does not distinguish acute from chronic changes.
Triceps skinfold measures fat stores only, not lean mass. ATI testing strategy: associate MAC/MUAC with chronic
malnutrition; weight changes (<7 days = acute; >7 days = chronic), skinfolds = fat stores, and MAC = muscle + fat.
Q5: A nurse is calculating a client's body mass index (BMI). The client weighs 175 lb and is 5 ft 9 in
tall. Which BMI category does this client fall into according to the Centers for Disease Control and
Prevention (CDC)?
A. Underweight (BMI 18.4 or less)
B. Healthy weight (BMI 18.5–24.9)
C. Overweight (BMI 25.0–29.9) [CORRECT]
D. Obese Class I (BMI 30.0–34.9)
Correct Answer: C
Rationale: BMI = weight (kg) / height (m²) or [weight (lb) / height (in²)] × 703. Converting: 175 lb × 703 = 123,025; height
5 ft 9 in = 69 in, 69² = 4761; 123, = 25.8, which falls into the overweight category (25.0–29.9). Choice A (<18.5) is
