HESI Gerontology Practice Test

Decreased bone density is a well-documented physiological change that commonly occurs with aging. As individuals get older, the process of bone remodeling—where old bone is replaced by new bone—can become less efficient. This can lead to an overall decrease in bone density, making bones more fragile and increasing the risk of fractures and osteoporosis. Age-related hormonal changes, such as decreased estrogen in women after menopause and reduced testosterone levels in men, also contribute to this decline in bone density. Additionally, factors like decreased physical activity, dietary deficiencies, and changes in calcium metabolism further exacerbate the loss of bone mass in older adults. Recognizing this change is essential for gerontological practice, as it emphasizes the importance of preventive measures, such as weight-bearing exercises and adequate calcium and vitamin D intake, to help preserve bone health in older populations.
