Clinical Nutritionist CCN Clinical Assessment and Nutritional Diagnosis 1 — Questions and Answers
Question 1: Which anthropometric measurement is most commonly used to assess central adiposity and cardiovascular risk?
- Waist circumference (Correct answer)
- Body mass index (BMI)
- Skinfold thickness
- Hip circumference
Correct answer: Waist circumference
Waist circumference directly measures abdominal fat and is a stronger predictor of metabolic syndrome and cardiovascular risk than BMI alone.
Question 2: Which laboratory marker is used to assess long-term glycemic control over approximately 2-3 months?
- Hemoglobin A1c (HbA1c) (Correct answer)
- Fasting blood glucose
- Postprandial glucose
- Fructosamine
Correct answer: Hemoglobin A1c (HbA1c)
HbA1c reflects average blood glucose levels over the lifespan of red blood cells (~2-3 months) and is the gold standard for monitoring diabetes management.
Question 3: In a nutritional assessment, what does a 24-hour dietary recall capture that a food frequency questionnaire (FFQ) does not?
- Detailed quantitative intake on a specific day (Correct answer)
- Habitual long-term dietary patterns
- Frequency of food group consumption over a year
- Meal timing and circadian patterns
Correct answer: Detailed quantitative intake on a specific day
A 24-hour recall collects precise quantitative data on all foods and beverages consumed in the previous 24 hours, capturing one day's actual intake in detail.
Question 4: Which visceral protein has the shortest half-life and is therefore most sensitive to acute changes in nutritional status?
- Prealbumin (transthyretin) — half-life ~2 days
- Albumin — half-life ~20 days
- Transferrin — half-life ~8-10 days
- Retinol-binding protein — half-life ~12 hours (Correct answer)
Correct answer: Retinol-binding protein — half-life ~12 hours
Retinol-binding protein has the shortest half-life of approximately 12 hours, making it the most sensitive indicator of acute changes in nutritional status.
Question 5: The Malnutrition Universal Screening Tool (MUST) incorporates which three components to assess malnutrition risk?
- BMI, unintentional weight loss, and acute disease effect (Correct answer)
- Albumin level, dietary intake, and functional status
- Waist circumference, appetite, and age
- Handgrip strength, BMI, and laboratory markers
Correct answer: BMI, unintentional weight loss, and acute disease effect
MUST scores BMI (0-2), percentage unintentional weight loss over 3-6 months (0-2), and acute disease effect (0 or 2), with total score guiding intervention.
Question 6: Which physical examination finding in a patient with malnutrition indicates significant depletion of subcutaneous fat stores?
- Hollow temples and visible ribs with loose skin (Correct answer)
- Peripheral edema
- Cheilosis and glossitis
- Koilonychia
Correct answer: Hollow temples and visible ribs with loose skin
Visible bony prominences with loose, redundant skin, hollow temples, and visible intercostal muscles indicate severe depletion of subcutaneous fat reserves.
