A patient returns to the intensive care unit following the surgical closure of a dehisced sternal wound. By which of the following methods does the nurse expect the patient's wound to heal?
1. primary intention
2. secondary intention
3. tertiary intention
4. recurrent surgical debridement
2
Rationale: Wounds that heal by secondary intention include open abdominal wounds, dehisced sternal wounds, and stage III and IV pressure ulcers. Wounds healing by primary intention tend to have minimal tissue loss, with skin edges being well approximated. Tertiary intention combines primary and secondary intention, often requiring the wound to be left open for a period of time, such as a few days. The sternal wound has been surgically closed. Although future surgical debridement may be necessary, it is not an expected plan of care.
