Introduction
This ATI RN Nutrition CMS Proctored Exam for the 2026/2027 academic cycle represents a
standardized assessment used in nursing programs to evaluate competency in nutrition care.
The examination measures understanding of nutrient requirements, therapeutic diets,
nutritional assessment techniques, and safe evidence-based interventions that support patient
health and disease management. Nutrition is a fundamental component of nursing care,
influencing patient outcomes across all healthcare settings and throughout the lifespan. This
examination addresses ten core domains essential to nutrition nursing practice: Nutritional
Assessment, Macronutrients and Micronutrients, Therapeutic Diets, Enteral and Parenteral
Nutrition, Nutrition Across the Lifespan, Fluid and Electrolyte Balance, Nutritional Support for
Disease Management, Cultural Considerations in Diet, Patient Education, and Evidence-Based
Nutrition Interventions. Each question reflects the complexity of clinical decision-making
required when providing nutrition care. All correct answers are presented in bold text, followed
by detailed rationales explaining nutritional priorities, patient safety considerations, and
evidence-based clinical decision-making.
Examination Instructions
,This examination consists of 70 multiple-choice questions in single-best-answer format. For
each question, select the ONE most appropriate answer from the options provided. Questions
include clinical scenarios requiring integration of knowledge, critical thinking, and clinical
judgment specific to nutrition nursing practice. Time allocation should average approximately 1-
1.5 minutes per question.
Examination Questions
Question 1
Domain: Nutritional Assessment
A nurse is conducting a nutritional assessment on a 65-year-old client. Which anthropometric
measurement is most accurate for evaluating long-term nutritional status?
A) Daily caloric intake
B) Body mass index (BMI)
C) Serum albumin level
D) 24-hour dietary recall
Rationale: Body mass index (BMI) is a reliable anthropometric measurement for evaluating
long-term nutritional status because it reflects body weight relative to height over time.
While serum albumin indicates protein status, it is affected by acute illness and inflammation.
Daily caloric intake and 24-hour recalls provide short-term intake data but are subject to recall
bias. The nurse should use multiple assessment methods including BMI, weight history, and
biochemical markers for comprehensive evaluation.
Question 2
Domain: Nutritional Assessment
A nurse is assessing a client's nutritional status using the Subjective Global Assessment (SGA).
Which component is included in this assessment?
A) 24-hour urinary nitrogen
B) Weight history and physical examination findings
C) Serum prealbumin level
D) Dual-energy X-ray absorptiometry (DEXA) scan
Rationale: The Subjective Global Assessment (SGA) is a clinical tool that includes weight
history, dietary intake changes, gastrointestinal symptoms, functional capacity, and physical
examination findings. It does not rely on laboratory values like urinary nitrogen or
,prealbumin. The SGA is validated for predicting nutrition-related complications and is
performed at the bedside without invasive testing.
Question 3
Domain: Nutritional Assessment
A nurse is evaluating the laboratory results of a client who is at risk for malnutrition. Which
serum protein has the shortest half-life and is most sensitive to acute changes in nutritional
status?
A) Albumin
B) Transferrin
C) Prealbumin (transthyretin)
D) Retinol-binding protein
Rationale: Prealbumin (transthyretin) has a half-life of approximately 2-3 days, making it the
most sensitive marker for acute changes in nutritional status. Albumin has a half-life of 18-20
days and is affected by hydration status and liver disease. Transferrin has a half-life of 8-10
days, and retinol-binding protein has a half-life of 12 hours but is less commonly used in
clinical practice. Prealbumin is the preferred marker for monitoring response to nutritional
interventions.
Question 4
Domain: Nutritional Assessment
A nurse is performing a nutritional screening on an older adult client using the Mini
Nutritional Assessment (MNA). Which finding would indicate the client is at risk for
malnutrition?
A) BMI of 26 kg/m²
B) Weight loss of 2% in the past month
C) Weight loss of 5% in the past 3 months
D) Serum albumin of 4.0 g/dL
Rationale: The Mini Nutritional Assessment (MNA) identifies weight loss of 5% or more in the
past 3 months as a significant risk factor for malnutrition in older adults. A BMI of 26 is within
normal range, and a 2% weight loss in one month is less concerning. A serum albumin of 4.0
g/dL is within normal limits. The MNA also evaluates dietary intake, mobility, and
psychological stress to provide a comprehensive nutritional risk assessment.
Question 5
, Domain: Macronutrients and Micronutrients
A nurse is providing education to a client about dietary sources of complete proteins. Which
food source should the nurse recommend as providing all essential amino acids?
A) Lentils
B) Brown rice
C) Chicken breast
D) Peanut butter
Rationale: Chicken breast is a complete protein source because it contains all nine essential
amino acids in adequate amounts. Animal-based proteins such as meat, poultry, fish, eggs,
and dairy are complete proteins. Lentils, brown rice, and peanut butter are plant-based
proteins that are incomplete and lack one or more essential amino acids. Clients who follow
vegetarian diets should be counseled on complementary protein combinations to ensure
adequate intake of all essential amino acids.
Question 6
Domain: Macronutrients and Micronutrients
A nurse is caring for a client with iron-deficiency anemia. Which food should the nurse
recommend to enhance the absorption of iron from plant-based sources?
A) Milk
B) Orange juice
C) Black tea
D) Whole wheat bread
Rationale: Vitamin C enhances the absorption of non-heme iron (plant-based iron) by
reducing ferric iron to the more absorbable ferrous form. Orange juice is a rich source of
vitamin C and should be consumed with plant-based iron sources such as beans, lentils, and
fortified cereals. Milk and tea can inhibit iron absorption, and whole wheat bread contains
phytates that bind iron and reduce absorption.
Question 7
Domain: Macronutrients and Micronutrients
A nurse is assessing a client who reports muscle cramps and tingling in the fingers. Which
electrolyte imbalance is most likely responsible for these symptoms?
A) Hypokalemia
