ATI RN Nutrition CMS Proctored Exam | 2023
Introduction
This ATI RN Nutrition CMS Proctored Exam for the 2023 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 green 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) Resting metabolic rate
Rationale: The Subjective Global Assessment (SGA) evaluates nutritional status through weight history,
dietary intake changes, gastrointestinal symptoms, functional capacity, and physical examination findings
including muscle wasting, fat loss, and edema. SGA is a validated clinical tool that correlates with patient
outcomes. It does not require laboratory values or metabolic measurements, making it practical for
clinical settings. The nurse should perform SGA as part of comprehensive nutritional screening.
Question 3
Domain: Nutritional Assessment
A client has a serum albumin level of 2.8 g/dL. Which interpretation by the nurse is correct?
A) Normal albumin level
B) Mild hypoalbuminemia indicating acute malnutrition
C) Low albumin level indicating possible protein deficiency or inflammation
D) Elevated albumin indicating dehydration
Rationale: Normal serum albumin ranges from 3.5-5.0 g/dL. A level of 2.8 g/dL indicates
hypoalbuminemia, which may reflect protein deficiency, chronic malnutrition, liver disease, or
inflammatory states. Albumin has a long half-life (20 days) and is more reflective of chronic rather than
acute nutritional changes. The nurse should consider albumin alongside other markers such as
prealbumin (half-life 2-3 days) and C-reactive protein to differentiate malnutrition from inflammation.
Question 4
Domain: Nutritional Assessment
A nurse is calculating a client's body mass index. The client weighs 165 pounds and is 5 feet 8 inches tall.
What is the client's BMI?
A) 22.4
B) 25.1
C) 27.3
D) 30.2
Rationale: BMI is calculated as weight in kilograms divided by height in meters squared. Converting:
165 lbs = 75 kg (165/2.2); 5'8" = 68 inches = 172.7 cm = 1.727 m. BMI = 75/(1.727)² = 25.1. A BMI of
25-29.9 indicates overweight. The nurse should use BMI as one component of nutritional assessment,
considering that it does not distinguish between fat mass and lean body mass. Waist circumference and
body composition analysis provide additional information.
Question 5
, Domain: Nutritional Assessment
A nurse is using the Mini Nutritional Assessment (MNA) for an elderly client. Which finding would
indicate risk for malnutrition?
A) BMI of 24
B) Weight loss of 3 pounds in the past month
C) Independent in activities of daily living
D) Consumes three meals daily
Rationale: The Mini Nutritional Assessment (MNA) screens elderly clients for malnutrition risk.
Unintentional weight loss is a significant indicator of malnutrition risk. The MNA evaluates
anthropometric measurements, dietary assessment, and subjective assessment. A score below 24 indicates
risk for malnutrition. The nurse should monitor elderly clients closely for weight changes, decreased
appetite, and functional decline that may contribute to nutritional deficits.
Question 6
Domain: Nutritional Assessment
A nurse is assessing a client for signs of protein-calorie malnutrition. Which clinical finding is most
characteristic?
A) Increased muscle mass
B) Peripheral edema and muscle wasting
C) Elevated serum transferrin
D) Hyperalbuminemia
Rationale: Protein-calorie malnutrition (kwashiorkor-marasmus spectrum) presents with peripheral
edema due to decreased oncotic pressure, muscle wasting from protein catabolism, and impaired wound
healing. Serum transferrin and albumin would be decreased, not elevated. The nurse should assess for
visible signs of malnutrition including temporal wasting, decreased grip strength, and delayed wound
healing, in addition to biochemical markers.
Question 7
Domain: Nutritional Assessment
A nurse is evaluating a client's 24-hour dietary recall. Which statement by the client indicates accurate
recall?
A) I always eat healthy foods
B) Yesterday I had oatmeal with milk for breakfast, a turkey sandwich with apple for
lunch, and grilled salmon with vegetables for dinner
