- Nutritional status using dietary history and physical examination (Correct answer)
- Hydration status only
- Bone mineral density
Correct answer: Nutritional status using dietary history and physical examination
The SGA assesses nutritional status by combining dietary history, weight change patterns, and physical examination findings.
Question 3: Which serum protein has the shortest half-life and is the most sensitive acute marker of nutritional change?
- Albumin (~21 days)
- Transferrin (~8–10 days)
- Prealbumin (~2–3 days)
- Retinol-binding protein (~12 hours) (Correct answer)
Correct answer: Retinol-binding protein (~12 hours)
