To prevent bedsores in immobilized patients, what should be done?

To prevent bedsores, also known as pressure ulcers, in immobilized patients, it is essential to change the patient's position regularly. The recommended practice is to reposition patients every two hours. This frequent repositioning helps redistribute pressure on the skin and underlying tissues, thereby reducing the risk of the development of bedsores.

By altering their position, you are allowing blood flow to reach the areas that would otherwise be under constant pressure, which is crucial for skin integrity and overall health. If a patient remains in a single position for too long, especially if they are unable to move on their own, it can lead to localized tissue damage and skin breakdown.

In terms of the other options, changing the position every four hours would not provide sufficient relief, as individuals at risk for bedsores require more frequent movement. Only repositioning when a patient requests it neglects the proactive approach needed for those who are immobilized and may not be able to feel discomfort or communicate their needs. Encouraging patient movement every hour would be beneficial but may not be feasible for all patients, particularly those who are entirely immobilized or have severe limitations. Hence, the most effective measure is to change the patient’s position every two hours to ensure their safety and well-being.
