ATI RN Nutrition Edition 12.0 Examination 2026/2027 | Verified Questions
,INTRODUCTION
This document contains 500 verified questions that comprehensively cover the full ATI RN Nutrition Edition 12.0 examination.
The questions are organized across six core domains: Nutrition Assessment & Screening; Macronutrients & Micronutrients;
Nutrition Across the Lifespan; Therapeutic Diets & Disease Management; Enteral & Parenteral Nutrition; and Food Safety, Cultural
Considerations & Patient Education. Each question is original and designed to reinforce the official ATI Testing RN Nutrition for
Nursing Edition 12.0 course objectives for actual exam readiness and nutrition proficiency, aligned to the 2026/2027 academic
year. The content emphasizes clinical reasoning and evidence-based logic consistent with ATI RN Nutrition frameworks, ASPEN
guidelines, and USDA Dietary Guidelines.
ACTUAL QUESTIONS
Domain 1: Nutrition Assessment & Screening
Question 1. Which laboratory value is most commonly used as a marker of recent protein status?
A. Hemoglobin
B. Serum sodium
C. Serum albumin or prealbumin
D. White blood cell count
Correct Answer: C
Rationale: Albumin and especially prealbumin reflect protein status; prealbumin has a shorter half-life and is more responsive to recent changes.
Question 2. A body mass index (BMI) of 32 kg/m² is classified as:
A. Obesity class I
B. Normal weight
C. Underweight
D. Overweight
Correct Answer: A
Rationale: BMI 30.0–34.9 is classified as obesity class I according to standard categories.
Question 3. The best initial screening tool for malnutrition risk in many acute care settings is:
A. A complete metabolic panel only
B. Relying solely on patient report of appetite
C. Waiting until visible muscle wasting appears
D. A validated nutrition screening tool such as the Malnutrition Screening Tool or similar
Correct Answer: D
Rationale: Validated screening tools identify patients who need full nutrition assessment early.
Question 4. Unintentional weight loss of greater than 10% over 6 months is considered:
A. Insignificant
B. A significant indicator of possible malnutrition
C. Normal for older adults
D. Only related to fluid status
Correct Answer: A
Rationale: Significant unintentional weight loss is a key clinical indicator prompting further nutrition assessment.
Question 5. Anthropometric measurements used in nutrition assessment include:
A. Only blood pressure
B. Only dietary recall
C. Only laboratory values
D. Height, weight, BMI, and sometimes skinfold or circumference measures
Correct Answer: D
Rationale: Anthropometrics provide objective data on body size and composition that complement dietary and laboratory data.
Question 6. A 24-hour dietary recall is limited because:
A. It is never useful
B. It may not represent usual intake and depends on memory
C. It requires no client cooperation
D. It measures only micronutrients
Correct Answer: B
Rationale: A single 24-hour recall may not reflect typical diet and is subject to recall bias; multiple days or food records improve accuracy.
Question 7. Which finding suggests possible dehydration affecting nutrition status?
A. Moist mucous membranes and normal skin turgor
B. Increased urine output only
C. Dry mucous membranes, decreased skin turgor, and elevated BUN
D. Low hematocrit always
Correct Answer: C
ATI RN Nutrition Edition 12.0 Examination 2026/2027 | Verified Questions
,Rationale: Clinical signs of dehydration and elevated BUN can indicate fluid deficit that influences nutrition and laboratory interpretation.
Question 8. Subjective Global Assessment (SGA) includes assessment of:
A. Weight change, dietary intake, gastrointestinal symptoms, functional capacity, and physical signs of malnutrition
B. Only laboratory values
C. Only BMI
D. Only appetite
Correct Answer: A
Rationale: SGA is a clinical method that integrates history and physical findings to classify nutrition status.
Question 9. Mid-arm circumference and triceps skinfold are used to estimate:
A. Hydration status only
B. Cardiac output
C. Bone density
D. Muscle and fat stores
Correct Answer: D
Rationale: These anthropometric measures help estimate somatic protein and fat reserves.
Question 10. A client with a pressure injury requires nutrition assessment because:
A. Increased protein and calorie needs support wound healing
B. Wounds never affect nutrition needs
C. Only fluid is important
D. Vitamins are irrelevant
Correct Answer: A
Rationale: Wound healing increases requirements for protein, energy, and certain micronutrients; assessment guides intervention.
Question 11. In nutrition assessment, which laboratory value is most commonly used as a marker of recent
protein status?
A. Hemoglobin
B. Serum albumin or prealbumin
C. Serum sodium
D. White blood cell count
Correct Answer: B
Rationale: Albumin and especially prealbumin reflect protein status; prealbumin has a shorter half-life and is more responsive to recent changes.
Question 12. Regarding macronutrients and micronutrients, a body mass index (BMI) of 32 kg/m² is classified
as:
A. Obesity class I
B. Normal weight
C. Underweight
D. Overweight
Correct Answer: A
Rationale: BMI 30.0–34.9 is classified as obesity class I according to standard categories.
Question 13. For nutrition across the lifespan, the best initial screening tool for malnutrition risk in many acute
care settings is:
A. A complete metabolic panel only
B. A validated nutrition screening tool such as the Malnutrition Screening Tool or similar
C. Waiting until visible muscle wasting appears
D. Relying solely on patient report of appetite
Correct Answer: B
Rationale: Validated screening tools identify patients who need full nutrition assessment early.
Question 14. In therapeutic diet management, unintentional weight loss of greater than 10% over 6 months is
considered:
A. Insignificant
B. Only related to fluid status
C. Normal for older adults
D. A significant indicator of possible malnutrition
Correct Answer: D
Rationale: Significant unintentional weight loss is a key clinical indicator prompting further nutrition assessment.
Question 15. When providing enteral or parenteral nutrition, anthropometric measurements used in nutrition
assessment include:
A. Only blood pressure
B. Only laboratory values
C. Height, weight, BMI, and sometimes skinfold or circumference measures
D. Only dietary recall
ATI RN Nutrition Edition 12.0 Examination 2026/2027 | Verified Questions
, Correct Answer: C

Question 16. Regarding food safety and education, a 24-hour dietary recall is limited because:
A. It is never useful
B. It measures only micronutrients
C. It requires no client cooperation
D. It may not represent usual intake and depends on memory
Correct Answer: D
Rationale: A single 24-hour recall may not reflect typical diet and is subject to recall bias; multiple days or food records improve accuracy.
Question 17. According to clinical nutrition principles, which finding suggests possible dehydration affecting
nutrition status?
A. Moist mucous membranes and normal skin turgor
B. Increased urine output only
C. Dry mucous membranes, decreased skin turgor, and elevated BUN
