Certified Nursing Assistant (CNA) Practice Exam

Which action should a nursing assistant take to prevent pressure ulcers in a bedridden resident?

1. Change the linens only when soiled

2. Massage bony prominences to improve circulation

3. Encourage the resident to sit up in bed for long periods

4. Ensure the resident's skin stays clean and dry

The correct answer is: Ensure the resident's skin stays clean and dry

The action of ensuring that the resident's skin stays clean and dry is fundamental in preventing pressure ulcers. Maintaining proper hygiene helps to eliminate moisture that can irritate the skin and contribute to breakdown, while dryness reduces the risk of friction and shearing forces that can lead to injuries. Additionally, when skin is clean, it can better recover from minor irritations and maintain its integrity. Regular skin assessments combined with proper cleansing routines play an essential role in preventing skin issues, including pressure ulcers. Keeping the skin dry also makes it easier to identify early signs of pressure ulcers, allowing for timely intervention. Inadequate attention to these factors can leave a resident vulnerable to skin problems, highlighting the importance of cleanliness and dryness in overall skin care.
