Nursing QUESTION #9309
Question 1
In wound care, the term debridement refers to:
  • Application of antibiotic ointment to a wound
  • Removal of devitalized, necrotic tissue from a wound to promote healing✔️
  • Covering a wound with an occlusive dressing
  • Irrigating a wound with normal saline
Correct Answer Explanation

Debridement is the removal of necrotic, devitalized, and contaminated tissue from a wound. It is essential for healing because:

  • Necrotic tissue acts as a bacterial culture medium
  • Devitalized tissue prevents granulation tissue formation
  • Dead tissue impairs leukocyte migration (immune function)
