Which statement best describes the composition of a nutritional assessment?

• A. Dietitian-prescribed meal plan only
• B. Genetic testing and imaging only
• C. History taking, physical assessment, biochemical data
• D. Exercise testing only

Answer: (C)

A nutritional assessment is built on gathering information from three interconnected sources: history taking, physical examination, and biochemical data. History taking reveals what a patient eats and drinks, dietary patterns, appetite, medical and social factors, and medications that can affect nutrition. The physical examination adds observable signs of nutritional status, such as muscle wasting, loss of subcutaneous fat, edema, skin or hair changes, and signs of deficiencies. Biochemical data provide objective evidence of nutritional adequacy and organ function, including lab values like proteins (albumin, prealbumin), electrolyte balance, micronutrient levels, and metabolic markers. These components together give a comprehensive picture of nutritional status and needs, guiding appropriate interventions. The other options describe either an intervention (a diet plan) or tests not typically part of the nutritional assessment (genetic testing, imaging, or exercise testing), which explains why they don’t best describe the composition of an assessment.
