✍️ Sample Clinical Nutritionist CCN Questions & Answers
1. Zinc deficiency is characteristically associated with which clinical finding?
Zinc deficiency causes hypogeusia (reduced taste acuity), anosmia, poor wound healing, growth retardation, and immune dysfunction.
2. Which nutrient keeps calcium in tact?
Food does not contain a lot of vitamin D. Although it is created by exposure to sunlight, many individuals do not get enough vitamin D. This vitamin is crucial for preserving blood calcium levels.
3. The Malnutrition Universal Screening Tool (MUST) incorporates which three components to assess malnutrition risk?
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.
4. In nutrition assessment, which anthropometric measurement is most strongly associated with visceral adiposity and metabolic syndrome risk?
Waist circumference directly reflects abdominal visceral fat accumulation, which is a stronger predictor of cardiometabolic risk than overall body weight or BMI alone.
5. Which amino acid is considered the primary precursor for the neurotransmitter serotonin?
Tryptophan is converted to 5-hydroxytryptophan (5-HTP) and then to serotonin via two enzymatic steps requiring vitamin B6 and other cofactors.
6. Which dietary intervention is first-line therapy for managing non-alcoholic fatty liver disease (NAFLD)?
A 5-10% reduction in body weight through lifestyle modification is the most effective intervention for improving liver histology, reducing hepatic steatosis, and decreasing inflammation in NAFLD.
