Final answer:
A nurse using the RYB classification system has documented a wound as 'red', indicating it is in the proliferative phase of healing and the priority is gentle cleansing to facilitate healing and protect new tissue.
Step-by-step explanation:
Using the RYB wound classification system, if a nurse documents a wound as 'red', the priority nursing intervention for this type of wound is to provide gentle cleansing of the wound. This intervention is key because a red wound is in the proliferative phase of healing, which means the focus is on protecting new tissue and fostering a healing environment. Interventions such as irrigation or debridement are not typically indicated for red wounds unless there is evidence of a significant bioburden or infection. Changing dressings should be done as needed, considering the amount of wound exudate and the recommendations for the specific dressing type used. It is essential for a nurse to monitor the wound closely for signs of infection, which include increased redness, swelling, and pain.
