The new nurse reads a client has a wound "healing by second intention" and ask what that means. Which description by the charge nurse is most accurate?

A. "The wound was stapled together after an infection was cleared up": This describes primary intention healing, where wound edges are surgically approximated after cleaning or debridement. Stapling or suturing is not part of second-intention healing. B. "The wound is an open cavity that will fill in with granulation tissue": Second-intention healing occurs when a wound is left open due to tissue loss, contamination, or infection risk. The wound gradually fills with granulation tissue, contracts, and epithelializes over time. This process allows natural healing without suturing. C. "The wound edges have been approximated and stitched together": This describes primary intention healing, not second intention. Suturing or closing the wound edges accelerates healing but does not involve open wound granulation, so this description is inaccurate. D. "The wound was contaminated by debris and can't be closed at all": While second-intention wounds may involve contamination or tissue loss, they are capable of healing naturally through granulation and epithelialization. The statement implies the wound cannot heal, which is incorrect; second-intention wounds do heal, albeit more slowly and with a higher risk of scarring.
