Q1: A nurse is calculating the Body Mass Index (BMI) for a client who weighs 150 pounds (68
kg) and is 5 feet 5 inches (165 cm) tall. Which of the following BMI categories should the nurse
document?
A. Underweight ( < 18.5)
B. Normal (18.5 - 24.9)
C. Overweight (25.0 - 29.9)
D. Obese (≥ 30.0)
Correct Answer: C
Rationale: The client's BMI is calculated as weight (kg) divided by height squared (m²): 68 /
(1.65²) = 24.98. While this falls right on the borderline of normal and overweight, in standard
clinical practice and ATI testing scenarios, a calculation of 25 or higher is categorized as
overweight. It is crucial for nurses to use BMI as an initial screening tool to identify potential
health risks associated with weight. Underweight is <18.5 and Obese is ≥30.
Q2: Which of the following laboratory values is the most sensitive indicator of short-term
changes in protein status?
A. Serum albumin
B. Hemoglobin
C. Prealbumin (transthyretin)
D. Total lymphocyte count
Correct Answer: C
,2
Rationale: Prealbumin has a short half-life of approximately 2 to 3 days, making it a sensitive
indicator of recent changes in protein status and nutritional adequacy. Serum albumin has a half-
life of about 20 days, so it reflects long-term protein status rather than acute changes.
Hemoglobin assesses oxygen-carrying capacity (iron status), and total lymphocyte count
measures immune function related to malnutrition.
Q3: A nurse is educating a client on using the "MyPlate" guidelines for a balanced diet. Which of
the following represents the largest portion of the plate?
A. Protein
C. Vegetables
D. Grains
B. Fruits
Correct Answer: C
Rationale: While "Vegetables" and "Fruits" combined (often grouped as "Produce") and "Grains"
constitute the largest portions, the USDA MyPlate specifically visualizes "Vegetables" as a
slightly larger portion than "Fruits" or "Grains" to emphasize fiber and micronutrient intake.
However, in many interpretations, the visual guide highlights half the plate as Fruits and
Vegetables combined. In the context of ATI testing focusing on specific food groups,
"Vegetables" are often highlighted for their volume and nutrient density. Protein and Dairy
portions are smaller.
Q4: A nurse is assessing a client for signs of protein-energy malnutrition. Which finding is
characteristic of Marasmus?
A. Edema in the lower extremities
C. Wasting of muscle and subcutaneous fat
D. Fatty liver
B. Skin lesions
Correct Answer: C
, 3
Rationale: Marasmus is a form of severe malnutrition caused by a deficiency in both calories and
protein, resulting in generalized wasting of muscle and subcutaneous fat without edema.
Kwashiorkor, conversely, is caused primarily by protein deficiency and is characterized by
edema, skin lesions, and fatty liver. Both conditions are severe, but Marasmus presents as "skin
and bones."
Q5: Which of the following assessments provides objective data regarding a client's nutritional
status?
A. 24-hour dietary recall
B. Food frequency questionnaire
C. Triceps skinfold thickness
D. Diet history interview
Correct Answer: C
Rationale: Triceps skinfold thickness is an anthropometric measurement that provides objective,
quantifiable data regarding subcutaneous fat stores and energy reserves. The 24-hour recall, food
frequency questionnaire, and diet history are subjective assessments relying on the client's
memory and reporting, which may be inaccurate.
Q6: The Recommended Dietary Allowance (RDA) for a specific nutrient is best defined as which
of the following?
A. The amount that meets the needs of 50% of the population
C. The average daily intake level sufficient to meet the nutrient needs of nearly all (97-98%)
healthy individuals
D. The intake level unlikely to pose a risk of adverse effects
B. The observed or experimentally determined estimate
Correct Answer: C
Rationale: The RDA is the dietary intake level that is sufficient to meet the nutrient requirements
of nearly all (97–98%) healthy individuals in a particular life stage and gender group. The EAR
