How does a CNA assist with wound care?

A Certified Nursing Assistant (CNA) plays a crucial role in the process of wound care by following specific protocols and working under the guidance of licensed nursing staff. In this case, the most appropriate way for a CNA to assist with wound care is by following the nurse's instructions and ensuring that the area is clean and dry. This is important because proper hygiene is essential to prevent infection and promote healing.

By adhering to the instructions given by the nurse, the CNA helps ensure that wound care practices are consistent with medical standards and tailored to the patient’s specific needs. Keeping the area clean and dry also aids in maintaining the healing environment for the wound, allowing for better recovery outcomes.

The other choices involve actions that CNAs are generally not trained or authorized to perform. For instance, applying medication directly to a wound or performing surgery would require professional nursing skills and knowledge that exceed the responsibilities of a CNA. Additionally, the practice of replacing bandages at a set time (like every 12 hours) might not be appropriate in every case, as the frequency of dressing changes should be based on the specific condition of the wound and the nurse's assessment rather than a fixed schedule.
