What is a key action for preventing pressure ulcers in a resident confined to bed?

1. Encouraging the resident to exercise in bed

2. Turning and positioning the resident according to a schedule

3. Providing extra bedding for warmth

4. Increasing the resident's fluid intake

The correct answer is: Turning and positioning the resident according to a schedule

Turning and positioning the resident according to a schedule is a fundamental practice in preventing pressure ulcers for those confined to bed. Pressure ulcers, also known as bedsores, typically develop when there is prolonged pressure on the skin, particularly over bony areas. By regularly changing the resident's position, caregivers alleviate pressure on specific areas, promoting blood flow and reducing the risk of skin breakdown. Scheduled repositioning can involve turning the resident every two hours or using specialized devices to offload pressure points. This proactive measure is crucial for maintaining skin integrity and overall health. While encouraging exercise, providing extra bedding, and increasing fluid intake can contribute to a resident's overall well-being, they do not specifically address the mechanical causes of pressure ulcers as effectively as scheduled repositioning does. Proper positioning and rotation are critical elements in a comprehensive care plan aimed at preventing these serious skin injuries.
