SECTION 1: Principles of Nutrition and Nutritional Assessment
Macronutrients, Micronutrients, Anthropometry, Biochemical Markers, and Dietary Assessment (Ch 1-4).
Q1. [Ch. 1] A nurse is teaching a client about macronutrients. The nurse explains that carbohydrates yield how
many kilocalories (kcal) per gram?
A. 4 kcal/g [CORRECT]
B. 7 kcal/g
C. 9 kcal/g
D. 0 kcal/g
Correct Answer: A
Rationale: Carbohydrates and proteins each yield 4 kcal/g, while fats (lipids) yield 9 kcal/g, and alcohol yields 7 kcal/g. These energy
densities are foundational to nutritional calculations. The nurse uses these values to evaluate meal plans, calculate enteral feeding
caloric content, and teach clients about energy balance.
Q2. [Ch. 1] A client asks the nurse how many calories are provided by 1 gram of dietary fat. Which response by
the nurse is correct?
A. 7 kcal/g
B. 9 kcal/g [CORRECT]
C. 12 kcal/g
D. 4 kcal/g
ATI RN Nutrition Edition 8.0 (2026) - Page 1
,Correct Answer: B
Rationale: Dietary fat yields 9 kcal/g, more than twice the energy density of carbohydrate or protein (4 kcal/g). This is why high-fat
foods contribute significantly to total caloric intake and weight gain. Alcohol yields 7 kcal/g but is not considered a macronutrient.
Q3. [Ch. 1] A nurse is calculating the caloric contribution of protein in a meal containing 50 g of protein. What
is the total caloric contribution of protein in this meal?
A. 450 kcal
B. 500 kcal
C. 200 kcal [CORRECT]
D. 350 kcal
Correct Answer: C
Rationale: Protein yields 4 kcal/g, so 50 g of protein provides 200 kcal (50 \u00d7 4 = 200). This calculation is essential for
evaluating nutritional adequacy, designing enteral feeding regimens, and counseling clients on macronutrient distribution. A typical
healthy diet allocates 10-35% of total calories to protein.
Q4. [Ch. 1] A nurse is counseling a client on increasing dietary fiber. According to current Dietary Guidelines,
what is the recommended daily fiber intake for adults?
A. 45-55 g/day
B. 70-90 g/day
C. 5-10 g/day
D. 14 g/1000 kcal (about 25-38 g/day for most adults) [CORRECT]
Correct Answer: D
Rationale: The Dietary Reference Intake (DRI) for fiber is approximately 14 g per 1,000 kcal of energy intake, which translates to
about 25 g/day for adult women and 38 g/day for adult men. Adequate fiber intake supports bowel function, glycemic control, and
cardiovascular health. Most Americans consume less than half the recommended amount.
Q5. [Ch. 1] A nurse is teaching a nutrition class about daily fluid requirements for healthy adults. Which
statement by the nurse is accurate?
A. Adults need approximately 1 mL of water per kcal of energy expended (about 30 mL/kg/day) [CORRECT]
B. Adults need 5 mL of water per kg of body weight daily
C. Adults only need to drink when thirsty
D. Adults require 100 mL of water per kg of body weight
Correct Answer: A
Rationale: The general recommendation for adult fluid intake is approximately 1 mL per kcal expended, or about 30 mL/kg/day,
which equals roughly 2,000-3,000 mL/day for most adults. Thirst is not always a reliable indicator, especially in older adults. Needs
increase with fever, diarrhea, vomiting, draining wounds, and increased physical activity.
Q6. [Ch. 1] A nurse is teaching a client about the USDA MyPlate tool. Which food group should occupy
approximately half of the plate according to MyPlate guidance?
A. Grains and protein
B. Fruits and vegetables [CORRECT]
C. Dairy and grains
D. Protein and dairy
Correct Answer: B
Rationale: According to MyPlate, fruits and vegetables should fill approximately half the plate, with grains making up about
one-quarter and protein about one-quarter. Dairy is represented by a small circle beside the plate. MyPlate is a visual tool based on the
Dietary Guidelines for Americans and emphasizes variety, proportion, and portion control.
Q7. [Ch. 2] A nurse calculates a client's body mass index (BMI). The client weighs 58 kg and is 1.65 m tall. What
is the BMI, and what is the corresponding classification?
ATI RN Nutrition Edition 8.0 (2026) - Page 2
, A. BMI 18.5, underweight
B. BMI 25.7, overweight
C. BMI 21.3, normal weight [CORRECT]
D. BMI 30.1, obese class I
Correct Answer: C
Rationale: BMI is calculated as weight in kg divided by height in meters squared (kg/m\u00b2). For this client: 58 \u00f7
(1.65)\u00b2 = 58 \u00f7 2.7225 = 21.3, which falls in the normal weight range. BMI classifications are: <18.5 underweight,
18.5-24.9 normal, 25-29.9 overweight, 30-34.9 obese class I, 35-39.9 obese class II, and \u226540 obese class III. BMI is a screening
tool; waist circumference and body composition provide complementary information.
Q8. [Ch. 2] A client has a BMI of 31.2. How should the nurse classify this client's weight status?
A. Obese class II (moderate)
B. Normal weight
C. Overweight
D. Obese class I (mild) [CORRECT]
Correct Answer: D
Rationale: BMI classifications are: 18.5-24.9 normal, 25-29.9 overweight, 30-34.9 obese class I, 35-39.9 obese class II, and
\u226540 obese class III. A BMI of 31.2 falls in the obese class I category. Obesity increases the risk of cardiovascular disease, type 2
diabetes, sleep apnea, and certain cancers; weight loss of even 5-10% improves outcomes.
Q9. [Ch. 2] A nurse measures an adult male client's waist circumference as 102 cm (40 in). Which interpretation
by the nurse is correct?
A. Indicates increased cardiovascular risk [CORRECT]
B. Suggests underweight status
C. Confirms normal BMI
D. Within healthy limits for males
Correct Answer: A
Rationale: Waist circumference \u2265102 cm (40 in) in men or \u226588 cm (35 in) in women indicates abdominal obesity and
increased cardiovascular risk independent of BMI. Central adiposity is metabolically active and is associated with insulin resistance,
dyslipidemia, and hypertension. This measure complements BMI for cardiometabolic risk stratification.
Q10. [Ch. 2] A nurse is performing a comprehensive nutritional assessment. Which anthropometric
measurement is most useful for tracking long-term nutritional status in adults?
A. Daily weight
B. Mid-arm muscle circumference (MAMC) and triceps skinfold thickness [CORRECT]
C. Waist-to-hip ratio only
D. Capillary refill time
Correct Answer: B
Rationale: Triceps skinfold (TSF) thickness and mid-arm muscle circumference (MAMC) are anthropometric measures of
subcutaneous fat and somatic protein stores, respectively, useful for tracking long-term nutritional status. TSF and MAMC together
provide a more complete picture of fat and muscle reserves than weight alone, especially in clients with fluid shifts.
Q11. [Ch. 2] A nurse is reviewing laboratory values for a client with suspected protein malnutrition. Which
serum protein reflects long-term (3-week) protein status and is most affected by liver synthesis?
A. Hemoglobin
B. Prealbumin
C. Albumin [CORRECT]
D. Transferrin
Correct Answer: C
ATI RN Nutrition Edition 8.0 (2026) - Page 3
, Rationale: Albumin has a half-life of approximately 20 days and reflects long-term (about 3 weeks) protein and visceral protein
status. However, albumin is also influenced by inflammation, hydration, and liver function, limiting its specificity. Normal serum
albumin is 3.5-5.0 g/dL; values below 3.5 g/dL suggest protein depletion but should be interpreted with clinical context.
Q12. [Ch. 2] A nurse evaluates a client's prealbumin level of 12 mg/dL (normal 15-36 mg/dL). What is the
correct interpretation?
A. Severe chronic malnutrition
B. End-stage renal disease
C. Normal nutritional status
D. Mild to moderate protein depletion reflecting short-term (1-2 week) status [CORRECT]
Correct Answer: D
Rationale: Prealbumin has a half-life of approximately 2-3 days, making it a sensitive marker of short-term (1-2 week) protein and
calorie status. A level of 12 mg/dL indicates mild to moderate protein depletion and warrants nutritional intervention and
re-evaluation within 1-2 weeks. Prealbumin responds rapidly to nutritional support, unlike albumin.
Q13. [Ch. 2] A nurse is reviewing a client's laboratory values for iron status. Which serum protein best reflects
total body iron stores and is the most sensitive marker of early iron deficiency?
A. Ferritin [CORRECT]
B. Hemoglobin
C. Serum iron
D. Transferrin saturation
Correct Answer: A
Rationale: Ferritin is the storage form of iron and is the most sensitive early marker of iron deficiency, declining before hemoglobin
or transferrin saturation change. Normal serum ferritin is approximately 30-300 ng/mL in men and 15-150 ng/mL in women. A
ferritin <30 ng/mL indicates iron deficiency anemia. Ferritin is also an acute-phase reactant and may be falsely elevated in
inflammation.
Q14. [Ch. 2] A nurse is conducting a dietary assessment. Which method is most useful for assessing a client's
typical intake of specific foods over the past month?
A. 24-hour recall
B. Food frequency questionnaire [CORRECT]
C. Direct observation of one meal
D. Estimated basal metabolic rate
Correct Answer: B
Rationale: A food frequency questionnaire asks the client to report the frequency and portion size of specific foods consumed over a
defined period (e.g., past month or year), providing a picture of usual dietary patterns. A 24-hour recall captures only one day and
may not represent typical intake. Direct observation captures only one meal.
Q15. [Ch. 2] A nurse is teaching a client how to complete a 3-day food record. Which instruction by the nurse is
most appropriate?
A. Skip recording snacks and beverages
B. Record intake for any 3 days at the end of the month
C. Record all food and beverage intake, including portion sizes, for 3 consecutive days (including 1 weekend
day) [CORRECT]
D. Estimate intake at the end of each week
Correct Answer: C
Rationale: A 3-day food record should include 3 consecutive days, including one weekend day, with foods and beverages recorded at
the time of consumption (not from memory) along with portion sizes. This method captures day-to-day variation and weekend eating
patterns. Estimating at the end of the week introduces recall bias; omitting snacks or beverages underestimates intake.

SECTION 1: Principles of Nutrition and Nutritional Assessment
Macronutrients, Micronutrients, Anthropometry, Biochemical Markers, and Dietary Assessment (Ch 1-4).
Q1. [Ch. 1] A nurse is teaching a client about macronutrients. The nurse explains that carbohydrates yield how
many kilocalories (kcal) per gram?
A. 4 kcal/g [CORRECT]
B. 7 kcal/g
C. 9 kcal/g
D. 0 kcal/g
Correct Answer: A
Rationale: Carbohydrates and proteins each yield 4 kcal/g, while fats (lipids) yield 9 kcal/g, and alcohol yields 7 kcal/g. These energy
densities are foundational to nutritional calculations. The nurse uses these values to evaluate meal plans, calculate enteral feeding
caloric content, and teach clients about energy balance.
Q2. [Ch. 1] A client asks the nurse how many calories are provided by 1 gram of dietary fat. Which response by
the nurse is correct?
A. 7 kcal/g
B. 9 kcal/g [CORRECT]
C. 12 kcal/g
D. 4 kcal/g
ATI RN Nutrition Edition 8.0 (2026) - Page 1
,Correct Answer: B
Rationale: Dietary fat yields 9 kcal/g, more than twice the energy density of carbohydrate or protein (4 kcal/g). This is why high-fat
foods contribute significantly to total caloric intake and weight gain. Alcohol yields 7 kcal/g but is not considered a macronutrient.
Q3. [Ch. 1] A nurse is calculating the caloric contribution of protein in a meal containing 50 g of protein. What
is the total caloric contribution of protein in this meal?
A. 450 kcal
B. 500 kcal
C. 200 kcal [CORRECT]
D. 350 kcal
Correct Answer: C
Rationale: Protein yields 4 kcal/g, so 50 g of protein provides 200 kcal (50 \u00d7 4 = 200). This calculation is essential for
evaluating nutritional adequacy, designing enteral feeding regimens, and counseling clients on macronutrient distribution. A typical
healthy diet allocates 10-35% of total calories to protein.
Q4. [Ch. 1] A nurse is counseling a client on increasing dietary fiber. According to current Dietary Guidelines,
what is the recommended daily fiber intake for adults?
A. 45-55 g/day
B. 70-90 g/day
C. 5-10 g/day
D. 14 g/1000 kcal (about 25-38 g/day for most adults) [CORRECT]
Correct Answer: D
Rationale: The Dietary Reference Intake (DRI) for fiber is approximately 14 g per 1,000 kcal of energy intake, which translates to
about 25 g/day for adult women and 38 g/day for adult men. Adequate fiber intake supports bowel function, glycemic control, and
cardiovascular health. Most Americans consume less than half the recommended amount.
Q5. [Ch. 1] A nurse is teaching a nutrition class about daily fluid requirements for healthy adults. Which
statement by the nurse is accurate?
A. Adults need approximately 1 mL of water per kcal of energy expended (about 30 mL/kg/day) [CORRECT]
B. Adults need 5 mL of water per kg of body weight daily
C. Adults only need to drink when thirsty
D. Adults require 100 mL of water per kg of body weight
Correct Answer: A
Rationale: The general recommendation for adult fluid intake is approximately 1 mL per kcal expended, or about 30 mL/kg/day,
which equals roughly 2,000-3,000 mL/day for most adults. Thirst is not always a reliable indicator, especially in older adults. Needs
increase with fever, diarrhea, vomiting, draining wounds, and increased physical activity.
Q6. [Ch. 1] A nurse is teaching a client about the USDA MyPlate tool. Which food group should occupy
approximately half of the plate according to MyPlate guidance?
A. Grains and protein
B. Fruits and vegetables [CORRECT]
C. Dairy and grains
D. Protein and dairy
Correct Answer: B
Rationale: According to MyPlate, fruits and vegetables should fill approximately half the plate, with grains making up about
one-quarter and protein about one-quarter. Dairy is represented by a small circle beside the plate. MyPlate is a visual tool based on the
Dietary Guidelines for Americans and emphasizes variety, proportion, and portion control.
Q7. [Ch. 2] A nurse calculates a client's body mass index (BMI). The client weighs 58 kg and is 1.65 m tall. What
is the BMI, and what is the corresponding classification?
ATI RN Nutrition Edition 8.0 (2026) - Page 2
, A. BMI 18.5, underweight
B. BMI 25.7, overweight
C. BMI 21.3, normal weight [CORRECT]
D. BMI 30.1, obese class I
Correct Answer: C
Rationale: BMI is calculated as weight in kg divided by height in meters squared (kg/m\u00b2). For this client: 58 \u00f7
(1.65)\u00b2 = 58 \u00f7 2.7225 = 21.3, which falls in the normal weight range. BMI classifications are: <18.5 underweight,
18.5-24.9 normal, 25-29.9 overweight, 30-34.9 obese class I, 35-39.9 obese class II, and \u226540 obese class III. BMI is a screening
tool; waist circumference and body composition provide complementary information.
Q8. [Ch. 2] A client has a BMI of 31.2. How should the nurse classify this client's weight status?
A. Obese class II (moderate)
B. Normal weight
C. Overweight
D. Obese class I (mild) [CORRECT]
Correct Answer: D
Rationale: BMI classifications are: 18.5-24.9 normal, 25-29.9 overweight, 30-34.9 obese class I, 35-39.9 obese class II, and
\u226540 obese class III. A BMI of 31.2 falls in the obese class I category. Obesity increases the risk of cardiovascular disease, type 2
diabetes, sleep apnea, and certain cancers; weight loss of even 5-10% improves outcomes.
Q9. [Ch. 2] A nurse measures an adult male client's waist circumference as 102 cm (40 in). Which interpretation
by the nurse is correct?
A. Indicates increased cardiovascular risk [CORRECT]
B. Suggests underweight status
C. Confirms normal BMI
D. Within healthy limits for males
Correct Answer: A
Rationale: Waist circumference \u2265102 cm (40 in) in men or \u226588 cm (35 in) in women indicates abdominal obesity and
increased cardiovascular risk independent of BMI. Central adiposity is metabolically active and is associated with insulin resistance,
dyslipidemia, and hypertension. This measure complements BMI for cardiometabolic risk stratification.
Q10. [Ch. 2] A nurse is performing a comprehensive nutritional assessment. Which anthropometric
measurement is most useful for tracking long-term nutritional status in adults?
A. Daily weight
B. Mid-arm muscle circumference (MAMC) and triceps skinfold thickness [CORRECT]
C. Waist-to-hip ratio only
D. Capillary refill time
Correct Answer: B
Rationale: Triceps skinfold (TSF) thickness and mid-arm muscle circumference (MAMC) are anthropometric measures of
subcutaneous fat and somatic protein stores, respectively, useful for tracking long-term nutritional status. TSF and MAMC together
provide a more complete picture of fat and muscle reserves than weight alone, especially in clients with fluid shifts.
Q11. [Ch. 2] A nurse is reviewing laboratory values for a client with suspected protein malnutrition. Which
serum protein reflects long-term (3-week) protein status and is most affected by liver synthesis?
A. Hemoglobin
B. Prealbumin
C. Albumin [CORRECT]
D. Transferrin
Correct Answer: C
ATI RN Nutrition Edition 8.0 (2026) - Page 3
, Rationale: Albumin has a half-life of approximately 20 days and reflects long-term (about 3 weeks) protein and visceral protein
status. However, albumin is also influenced by inflammation, hydration, and liver function, limiting its specificity. Normal serum
albumin is 3.5-5.0 g/dL; values below 3.5 g/dL suggest protein depletion but should be interpreted with clinical context.
Q12. [Ch. 2] A nurse evaluates a client's prealbumin level of 12 mg/dL (normal 15-36 mg/dL). What is the
correct interpretation?
A. Severe chronic malnutrition
B. End-stage renal disease
C. Normal nutritional status
D. Mild to moderate protein depletion reflecting short-term (1-2 week) status [CORRECT]
Correct Answer: D
Rationale: Prealbumin has a half-life of approximately 2-3 days, making it a sensitive marker of short-term (1-2 week) protein and
calorie status. A level of 12 mg/dL indicates mild to moderate protein depletion and warrants nutritional intervention and
re-evaluation within 1-2 weeks. Prealbumin responds rapidly to nutritional support, unlike albumin.
Q13. [Ch. 2] A nurse is reviewing a client's laboratory values for iron status. Which serum protein best reflects
total body iron stores and is the most sensitive marker of early iron deficiency?
A. Ferritin [CORRECT]
B. Hemoglobin
C. Serum iron
D. Transferrin saturation
Correct Answer: A
Rationale: Ferritin is the storage form of iron and is the most sensitive early marker of iron deficiency, declining before hemoglobin
or transferrin saturation change. Normal serum ferritin is approximately 30-300 ng/mL in men and 15-150 ng/mL in women. A
ferritin <30 ng/mL indicates iron deficiency anemia. Ferritin is also an acute-phase reactant and may be falsely elevated in
inflammation.
Q14. [Ch. 2] A nurse is conducting a dietary assessment. Which method is most useful for assessing a client's
typical intake of specific foods over the past month?
A. 24-hour recall
B. Food frequency questionnaire [CORRECT]
C. Direct observation of one meal
D. Estimated basal metabolic rate
Correct Answer: B
Rationale: A food frequency questionnaire asks the client to report the frequency and portion size of specific foods consumed over a
defined period (e.g., past month or year), providing a picture of usual dietary patterns. A 24-hour recall captures only one day and
may not represent typical intake. Direct observation captures only one meal.
Q15. [Ch. 2] A nurse is teaching a client how to complete a 3-day food record. Which instruction by the nurse is
most appropriate?
A. Skip recording snacks and beverages
B. Record intake for any 3 days at the end of the month
C. Record all food and beverage intake, including portion sizes, for 3 consecutive days (including 1 weekend
day) [CORRECT]
D. Estimate intake at the end of each week
Correct Answer: C
Rationale: A 3-day food record should include 3 consecutive days, including one weekend day, with foods and beverages recorded at
the time of consumption (not from memory) along with portion sizes. This method captures day-to-day variation and weekend eating
patterns. Estimating at the end of the week introduces recall bias; omitting snacks or beverages underestimates intake.
