NUR 314 HESI RN Case Studies
Altered Nutrition
2026/2027 HESI Testing Standards
A comprehensive 45-question examination aligned with the HESI RN Case Study format for altered nutrition. Each
question has been carefully constructed to reflect current 2026-2027 nursing practice standards, evidence-based
nutritional interventions, and the clinical reasoning required for successful HESI RN examination performance.
Examination Structure
This examination is organized into five sections covering the full spectrum of altered nutrition nursing practice. Each
section addresses specific competencies required for HESI RN Case Study mastery, ranging from foundational
nutritional assessment through complex case management with multisystem involvement. Questions are calibrated to
a cognitive level distribution of approximately 25% recall, 50% application, and 25% analysis, mirroring the HESI
examination blueprint.
Question Format
• 80% scenario-based case studies requiring integration of nutritional assessment, pathophysiology, pharmacology,
and nursing interventions.
• 20% direct recall and concept identification questions reinforcing core nutritional principles, laboratory markers, and
deficiency manifestations.
• Each question includes one correct answer (out of four options) and a detailed HESI-specific rationale explaining
why the correct answer is best and why distractors are incorrect, including pathophysiology and evidence-based
practice.
How to Use This Exam
Approach each question using the nursing process and clinical judgment model: recognize cues (assessment
findings), analyze cues (identify abnormalities), prioritize hypotheses (determine most urgent needs), generate
solutions (planning), take action (interventions), and evaluate outcomes. After completing each section, review the
rationales for both correct and incorrect responses to reinforce learning. Rationales include pathophysiology, nursing
interventions, and evidence-based practice. This exam serves both as HESI preparation and as a continuing
competency resource for nursing practice.

Section 1: Nutritional Assessment and Screening
Comprehensive Nutritional History, Physical Examination, & Diagnostic Testing
Q1: A 78-year-old female is admitted to the medical-surgical unit with pneumonia. The nurse is completing a
comprehensive nutritional assessment. Which finding is the most reliable indicator of long-term protein status?
A. Serum albumin level of 2.8 g/dL [CORRECT]
B. Serum prealbumin level of 12 mg/dL
C. Total lymphocyte count of 1,200/mm³
D. Hemoglobin level of 10.5 g/dL
Correct Answer: A
Rationale: Serum albumin has a half-life of approximately 20 days, making it a reliable indicator of long-term (chronic)
protein status rather than acute changes. A level <3.0 g/dL indicates protein depletion. Prealbumin (half-life 2-3 days)
reflects short-term/acute protein status and recent dietary intake. Total lymphocyte count is a marker of immune function
affected by malnutrition but is nonspecific. Hemoglobin reflects iron status and anemia, not overall protein status.
Q2: A nurse is assessing a 68-year-old male who has lost 15 pounds in the past 3 months unintentionally. Which
anthropometric measurement best correlates with visceral protein stores and overall nutritional reserve?
A. Body Mass Index (BMI) of 19.5 kg/m²
B. Mid-upper arm circumference (MUAC) of 22 cm [CORRECT]
C. Triceps skinfold thickness of 8 mm
D. Waist-to-hip ratio of 0.95
Correct Answer: B
Rationale: Mid-upper arm circumference (MUAC) correlates with visceral protein stores, muscle mass, and overall
nutritional reserve. Combined with triceps skinfold (TSF), it allows calculation of arm muscle circumference, an indicator
of somatic protein status. BMI reflects overall weight-for-height but does not differentiate muscle from fat. Triceps skinfold
alone estimates body fat. Waist-to-hip ratio assesses cardiovascular risk, not nutritional status. Unintentional weight loss
>5% in 3 months requires nutritional intervention.
Q3: A nurse is performing a comprehensive nutritional history on a 45-year-old female with Crohn's disease. The
patient asks why a 24-hour dietary recall is being used. The nurse's best response is:
A. "The 24-hour recall provides a detailed analysis of your typical eating patterns and food preferences over time."
B. "The 24-hour recall is a quick method to identify what you ate in the past day, but may not represent your usual
intake." [CORRECT]
C. "The 24-hour recall is the most accurate method for measuring your long-term nutritional status."
D. "The 24-hour recall is used only to count calories consumed in the past 24 hours."
Correct Answer: B
Rationale: The 24-hour dietary recall asks the patient to recall all foods and beverages consumed in the previous 24 hours.
It is quick and easy but may not represent the patient's usual intake due to day-to-day variation, recall bias, and the patient
may not eat the same foods daily. Food diaries/records (3-7 days) and food frequency questionnaires provide better data on
typical patterns. The 24-hour recall is a starting point that requires follow-up assessment for a comprehensive picture.
Q4: A 72-year-old male is being screened for malnutrition using the Malnutrition Universal Screening Tool
(MUST). The patient has a BMI of 18.5 kg/m² and has unintentionally lost 8% of his body weight over the past 6
