The nurse explains that Bryant's traction is reserved for children who weigh less than how many pounds?

Choice A reason: Tobacco use accelerates bone loss by reducing osteoblast activity and blood flow to bones, increasing osteoporosis risk. Cutting down on smoking improves bone density by enhancing bone formation and reducing resorption, a key preventive measure for women.
Choice B reason: Limiting alcohol to two drinks daily is not specific enough, as even moderate alcohol can impair calcium absorption and osteoblast function, increasing osteoporosis risk. Guidelines recommend minimal alcohol consumption, making this less accurate for prevention.
Choice C reason: Strengthening exercises (e.g., resistance training) stimulate osteoblast activity, increasing bone density and strength. This is critical for preventing osteoporosis, as mechanical stress on bones enhances mineralization, reducing fracture risk in women, especially postmenopausal.
Choice D reason: Calcium and vitamin D are essential for bone health. Calcium forms bone matrix, and vitamin D enhances its absorption. Adequate intake prevents bone resorption, maintaining bone density and reducing osteoporosis risk, making this a cornerstone of prevention.
Choice E reason: Weight-bearing exercises like walking stimulate bone formation by applying mechanical stress, increasing osteoblast activity. Walking 30 minutes three times weekly improves bone density and reduces fracture risk, making it an effective strategy for osteoporosis prevention in women.

Choice A reason: Positioning with hips flexed at 90 degrees is inappropriate for Buck’s traction, which is a skin traction applied to the lower leg to align fractures. Excessive hip flexion can disrupt traction alignment and increase discomfort or complications.
Choice B reason: Weights in Buck’s traction must hang freely to maintain constant force for fracture alignment. Contact with the floor negates the traction’s effect, risking bone misalignment and delayed healing, making this an incorrect care practice.
Choice C reason: Checking for skin irritation is critical in Buck’s traction, as prolonged pressure from straps or bandages can cause pressure ulcers or skin breakdown. Regular skin assessment ensures early detection and prevention of complications, maintaining the traction’s safety and efficacy.
Choice D reason: Releasing weights disrupts the continuous force needed for fracture alignment in Buck’s traction. This can lead to bone displacement, increased pain, or delayed healing, making scheduled weight release an inappropriate and harmful practice.
