The nurse is providing discharge instructions to a patient with multiple lacerations and puncture wounds following a motor vehicle accident. Which statement by the patient indicates an understanding of the instructions?
A) "I should remove any scabs that form."
B) "The scab helps with wound repair."
C) "Scabs interfere with healing."
D) "Scabs prevent the wound edges from coming together."
B) "The scab helps with wound repair."
Explanation: A) The scab that forms during the repair process provides a natural "dressing" for the surface of the wound while repair and regeneration occur underneath; therefore, it should not be removed.
B) During the inflammatory phase of wound healing, an inflammatory exudate seeps out of the wound bed. As it dries over the provisional matrix, it forms a scab (eschar) that contracts, pulling the wound edges closer together and preventing surface microorganisms from penetrating the wound bed. This scab provides a natural "dressing" for the surface of the wound while repair and regeneration occur underneath.
C) A scab (eschar) contracts, pulling the wound edges closer together and preventing surface microorganisms from penetrating the wound bed. It does not interfere with healing, but rather, acts as a natural "dressing" for the surface of the wound while repair and regeneration occur underneath.
