Final answer:
The reduced bone mass in Tess's hip, femur, and vertebrae after her fall suggests that she has osteoporosis, a condition leading to fragile bones that are more prone to fractures in elderly individuals.
Correct option is a.
Step-by-step explanation:
After Tess's fall and her fractured right femur, the medical condition suggested by the reduced bone mass in her right hip, femur, and vertebrae is osteoporosis. Osteoporosis is characterized by a reduction in bone density and mass, leading to fragile bones that are more susceptible to fractures, even from minor falls or stresses. Elderly individuals, like Tess, are at increased risk for hip fractures due to weakened bones. These fractures typically require surgical treatment and are followed by physical therapy and a risk of complications such as deep vein thrombosis and pneumonia due to immobility during the recovery period.
