Final answer:
The most appropriate nursing action would be to explain that the procedure was performed incorrectly and provide clear feedback to the patient.
Step-by-step explanation:
The most appropriate nursing action in this situation would be option A: explain that the procedure was performed incorrectly. It is important for the nurse to provide clear and concise feedback to the patient about the incorrect procedure. By explaining the mistake, the nurse can educate the patient on the correct technique to ensure proper wound care and prevent complications.
Options B, C, and D may not be the most appropriate actions in this scenario. Changing the dressing again to demonstrate the correct technique (option B) may not be necessary if the nurse can effectively communicate the correct procedure verbally. Praising the patient for the procedure done (options C and D) without addressing the mistakes would not promote learning and improvement.
