Healing by secondary intention would occur in which of the following patients?
sutured surgical wound
stage IV ulcer
sunburn
paper cut
The Correct Answer is B
A. sutured surgical wound: Sutured wounds have edges approximated and heal by primary intention (direct epithelialization with minimal scarring).
B. stage IV ulcer: Stage IV pressure/decubitus ulcers have large tissue loss and damaged margins so they heal by secondary intention (granulation, contraction, lots of scar tissue).
C. sunburn: Superficial epithelial injury (sunburn) typically heals by regeneration of epithelium, not secondary-intention wound healing.
D. paper cut: Small clean lacerations with approximated edges heal by primary intention after closure (or spontaneously with minimal scarring).
