If a surgical wound dehisces after vomiting, what should the nurse's first action be?

When a surgical wound dehisces, or reopens, following an episode of vomiting, the priority is to protect the wound and prevent further complications. The best initial action is to cover the wound with sterile moist dressings. This helps to keep the area clean, minimize the risk of infection, and protect the underlying tissues while also managing any potential fluid loss.

Covering the wound promptly is critical because an exposed wound can lead to increased contamination and risk of infection, which can adversely affect the patient's recovery. After ensuring the wound is appropriately protected, the nurse can then proceed to notify the physician, assess vital signs, and document the incident. However, initial dressing is vital for safeguarding the wound area.
