During a routine health screening of an adult female, the nurse notes several changes that have occurred over the past year. Which change indicates the need for a bone density screening?

A. Lower body mass index (BMI): A lower BMI is a known risk factor for osteoporosis, especially in older adults. However, on its own, it does not immediately trigger the need for a bone density scan unless accompanied by other risk indicators like fractures or height loss.B. Diminished appetite: Loss of appetite may contribute to poor nutritional intake, including calcium and vitamin D, which can impact bone health over time. Still, this symptom alone does not directly prompt a bone density screening without other supporting signs.C. Decreased height: A measurable decrease in height may suggest vertebral compression fractures, a hallmark of osteoporosis. This is a key indicator that warrants further evaluation with a bone density scan (DEXA) to assess for bone loss.D. 15 lb (6.8 kg) weight loss: While unintentional weight loss may be a concern for many conditions, including cancer or malnutrition, it is not a specific trigger for bone density testing unless associated with other risk factors or signs of bone demineralization.
