What must a CNA perform to prevent a pressure ulcer?

To effectively prevent a pressure ulcer, a certified nursing assistant must regularly reposition the patient and check their skin integrity. Pressure ulcers, also known as bedsores, develop due to prolonged pressure on the skin, which can impede blood flow and lead to tissue damage. By changing the patient's position at regular intervals, the CNA helps alleviate pressure on vulnerable areas of the body, particularly over bony prominences like the heels, sacrum, and hips.

Additionally, checking skin integrity is vital to catch any early signs of pressure damage, allowing for timely interventions. Monitoring the skin ensures that any redness, swelling, or breakdown can be addressed before progressing to more serious stages of pressure ulcers. This proactive approach is essential for maintaining the overall health and well-being of patients, especially those who are immobile or have limited mobility.

In contrast, reducing fluid intake, encouraging long periods of bed rest, and applying moisturizing lotion only are ineffective strategies for preventing pressure ulcers. Reducing fluid intake can lead to dehydration, affecting skin health, while long periods of immobility increase the risk of pressure sore development. Simply applying lotion without addressing positioning does not eliminate the risk of pressure ulcers, as it does not relieve the underlying pressure on the skin.
