A nurse is teaching an older adult client who has osteoporosis about beginning a program of regular physical activity.Which of the following recommendations should the nurse make?

Choice A rationaleStretching exercises primarily improve flexibility and range of motion by elongating muscles and connective tissues. While beneficial for overall fitness, they do not directly address bone density loss, which is the primary concern in osteoporosis. Osteoporosis requires weight-bearing activities to stimulate bone formation.Choice B rationaleRiding a bicycle is a low-impact aerobic exercise that improves cardiovascular health and muscle strength. However, because it is non-weight-bearing, it does not provide the mechanical stress necessary to promote bone density and is therefore not the most effective exercise for osteoporosis management.Choice C rationaleHigh-impact aerobics, such as jumping and running, can increase the risk of fractures in individuals with osteoporosis due to the stress placed on weakened bones. These types of exercises should generally be avoided to prevent injury.Choice D rationaleWalking briskly is a weight-bearing exercise that applies moderate stress to the bones, stimulating osteoblast activity and promoting bone density. Regular brisk walking can help slow bone loss and reduce the risk of fractures in older adults with osteoporosis.
