Final answer:
To prevent osteoporosis-related fractures in menopausal women, a nurse should encourage participation in weight-bearing activities and promote a diet high in calcium and vitamin D.
Step-by-step explanation:
The primary prevention strategy a community health nurse should implement to address the increase in the occurrence of osteoporosis-related fractures in menopausal women is to encourage clients to participate in weight-bearing activities. After menopause, women's ovaries reduce in size and cease production of estrogen, which promotes bone matrix production and osteoblastic activity, leading to increased bone mass loss. Engaging in weight-bearing exercise is key in building and maintaining bone density, which is a critical component in preventing osteoporosis. Furthermore, a diet rich in calcium and vitamin D should also be encouraged to support bone health from a young age.
