Calcium absorption diminishes with reduced physical activity because of decreased bone stimulation. Therefore, encouraging the client to increase physical activity, such as by walking in the hall, helps minimize calcium loss. Turning or repositioning the client every 2 hours wouldn't increase activity sufficiently to minimize bone loss. Providing dairy products and supplemental feedings wouldn't lessen calcium loss even if the dairy products and feedings contained extra calcium because the additional calcium doesnt increase bone stimulation or osteoblast activity.
