Which tests are described as used for older adults to assess nutritional status, including bone health?

• A. Blood Tests
• B. Diet History
• C. X-Ray
• D. Bone Density Tests and MRI

Answer: (D)

In older adults, assessing nutritional status with a focus on bone health relies on tests that directly reveal bone strength. Bone density testing measures how much mineral is in the bones, helping diagnose osteoporosis and estimate fracture risk, which are closely tied to nutrition (adequate calcium, vitamin D, and protein support bone health). MRI adds detailed visualization of bone and surrounding tissues when a more complete picture is needed—such as evaluating bone quality, marrow, or complex injuries—though it isn’t a routine screen for nutrition itself. Other options don’t target bone health as directly: blood tests show general nutritional markers but not bone density, diet history reflects intake rather than current bone status, and X-rays can show obvious bone changes but are less sensitive for detecting early bone loss.
