NUTRITION ATI RN PROCTORED EXAM — PRACTICE EXAM
Question 1: A nurse is caring for a client who expresses a desire to lose weight. Which of the
following actions should the nurse take first?
A. Recommend checking weight once weekly.
B. Obtain a 24-hr dietary recall.
C. Assist with creating an exercise plan.
D. Initiate a plan for diet modification.
ANSWER ■: B — Obtain a 24-hr dietary recall.
Explanation: According to the nursing process, the nurse should always assess the client before planning
or implementing nursing interventions. Obtaining a 24-hour dietary recall is an assessment tool that provides
baseline data regarding the client's nutritional intake and eating habits, allowing the nurse to tailor
subsequent modifications. Checking weight, creating an exercise plan, and initiating diet modifications are
all physical interventions that occur after a thorough assessment is completed.
Question 2: A nurse is performing a comprehensive nutritional assessment on a client. After
reviewing the client's laboratory results, which of the following findings should the nurse
report to the provider as an indication of severe protein-calorie malnutrition?
A. WBC count 6,000/mm3
B. Sodium 139 mEq/L
C. Prealbumin 8 mg/dL
D. Thyroxine (T4) 9.2 mcg/dl
ANSWER ■: C — Prealbumin 8 mg/dL
Explanation: Prealbumin is a highly sensitive clinical indicator of acute nutritional status because of its short
half-life of 2 days. The normal reference range for prealbumin is 15 to 36 mg/dL. A value of 8 mg/dL
indicates severe protein-calorie malnutrition and must be reported immediately. A WBC count of
6,000/mm3, serum sodium of 139 mEq/L, and Thyroxine (T4) of 9.2 mcg/dL are all within expected normal
reference ranges.

Question 3: A nurse is assessing an older adult client who has experienced a 5% weight loss
in the past 30 days. Which of the following clinical findings should the nurse identify as an
indication of malnutrition?
A. Moist skin
B. Ankle edema
C. Hyperreflexia
D. Dilated pupils
ANSWER ■: B — Ankle edema
Explanation: Protein-energy malnutrition leads to a drop in serum albumin levels (hypoalbuminemia).
Albumin is responsible for maintaining colloid osmotic pressure in the vascular system. When albumin
decreases, fluid shifts from the blood vessels into the interstitial tissues, causing peripheral edema, such as
ankle edema. Moist skin is a sign of adequate hydration, while hyperreflexia and dilated pupils are
associated with neurological disorders or substance toxicity rather than protein malnutrition.
Question 4: A nurse is reviewing the laboratory values of a group of clients. Which of the
following clients should the nurse identify as experiencing dehydration?
A. A client who has a potassium level of 4.4 mEq/L
B. A client who has a hematocrit of 45%
C. A client who has a sodium level of 150 mEq/L
D. A client who has a BUN of 18 mg/dl
ANSWER ■: C — A client who has a sodium level of 150 mEq/L
Explanation: A serum sodium level of 150 mEq/L is elevated (hypernatremia), which is a classic
manifestation of dehydration due to hemoconcentration (loss of body water in excess of sodium). The other
values—potassium 4.4 mEq/L, hematocrit 45%, and BUN 18 mg/dL—are all within normal, expected
laboratory reference ranges.
