Final answer:
The Subjective Global Assessment evaluates nutritional status using dietary intake, weight history, and gastrointestinal symptoms to provide a comprehensive view of a patient's nutritional state.
Step-by-step explanation:
The Subjective Global Assessment (SGA) utilizes a variety of components to evaluate the nutritional status of patients. The correct components of SGA are:
- Dietary intake
- Weight history
- Gastrointestinal symptoms
This suggests that the right answer to the question about what SGA uses to evaluate nutritional status is: Weight history, dietary intake, and gastrointestinal symptoms. The SGA is particularly useful as it balances clinical judgment with objective data to get a comprehensive view of a patient's nutritional state without relying solely on laboratory indices or physical measurements like arm anthropometry.
