ATI NUTRITION PROCTORED EXAM 2023 - STUDY GUIDE
DOCUMENT OVERVIEW:
• This comprehensive 200-question study guide is designed for self-assessment and
Active Recall learning—attempt each question before checking the answer, then
review the EXPERT RATIONALE to strengthen understanding of nutritional
principles and nursing applications.
• The exam covers all major ATI Nutrition domains including nutritional assessment,
medical nutrition therapy, life-stage nutrition, macronutrients/micronutrients, and
clinical applications—use this material to identify weak areas and reinforce mastery
before the proctored exam.
QUESTION 1
A nurse is providing nutritional counseling to a client who has celiac disease.
Which of the following foods should the nurse recommend that the client
AVOID?
A) Quinoa
B) Brown rice
C) Barley
D) Potatoes
E) Corn
✓ CORRECT ANSWER: C) Barley
EXPERT RATIONALE: Barley contains gluten, a protein that triggers an autoimmune
response in individuals with celiac disease. Celiac disease requires strict avoidance
of all gluten-containing grains (wheat, barley, rye). Quinoa, brown rice, potatoes,
,and corn are all naturally gluten-free and are appropriate food choices for clients
with celiac disease.
QUESTION 2
A nurse is reviewing the lab results for a client with protein malnutrition.
Which of the following serum values would the nurse expect to be
DECREASED?
A) Albumin
B) Glucose
C) Sodium
D) Cholesterol
E) Potassium
✓ CORRECT ANSWER: A) Albumin
EXPERT RATIONALE: Serum albumin is a visceral protein marker that indicates
protein nutritional status. Decreased albumin (<3.5 g/dL) indicates protein
malnutrition or liver disease. Albumin has a half-life of approximately 20 days,
making it useful for assessing intermediate protein status. Glucose, sodium,
cholesterol, and potassium are not indicators of protein malnutrition specifically.
QUESTION 3
A nurse is calculating the total daily caloric needs for a client using the Harris-
Benedict equation. Which of the following factors is MOST important when
using this equation?
A) Age and weight only
B) Height, weight, age, and activity level
,C) Metabolic rate and medications
D) Dietary preferences and food allergies
E) Lipid levels and triglycerides
✓ CORRECT ANSWER: B) Height, weight, age, and activity level
EXPERT RATIONALE: The Harris-Benedict equation calculates Basal Metabolic Rate
(BMR) using height, weight, age, and sex. Activity factor is then multiplied to
estimate Total Daily Energy Expenditure (TDEE). This evidence-based formula
provides a personalized caloric estimate necessary for appropriate nutritional
planning across the lifespan and in various health conditions.
QUESTION 4
A client with type 2 diabetes asks a nurse about the glycemic index. Which
explanation is MOST accurate?
A) It measures the total amount of carbohydrates in a food
B) It measures how quickly a food raises blood glucose compared to pure glucose
C) It measures the fat content of a food
D) It is the same as the glycemic load
E) It is only relevant for insulin-dependent diabetics
✓ CORRECT ANSWER: B) It measures how quickly a food raises blood glucose
compared to pure glucose
EXPERT RATIONALE: The glycemic index (GI) ranks foods on how rapidly they raise
blood glucose levels compared to pure glucose (reference value = 100). Low GI
foods (<55) produce smaller blood glucose spikes, making them beneficial for blood
glucose management in diabetes. Understanding GI helps clients make informed
food choices to maintain better glycemic control.
, QUESTION 5
A nurse is assessing a client's nutritional status. Which anthropometric
measurement is MOST reliable for assessing acute protein malnutrition?
A) Height
B) Triceps skinfold thickness
C) Mid-arm circumference
D) Body mass index
E) Hip circumference
✓ CORRECT ANSWER: C) Mid-arm circumference
EXPERT RATIONALE: Mid-arm circumference (MAC) reflects muscle mass and is an
indicator of protein status. When combined with triceps skinfold thickness to
calculate Mid-arm Muscle Circumference (MAMC), it provides more reliable
assessment of acute protein malnutrition. MAC is sensitive to short-term changes in
protein stores, making it more useful than other anthropometric measures for
detecting recent nutritional decline.
QUESTION 6
A client has a BMI of 18.5. The nurse interprets this BMI as:
A) Underweight
B) Normal weight
C) Overweight
D) Obese Class I
E) Obese Class II
✓ CORRECT ANSWER: B) Normal weight
