Which of the following is a true statement about impaired skin integrity?
a. Stage III pressure ulcer cannot regress to stage II because the subcutaneous tissues regenerate.
b. Stasis ulcer is another term for pressure ulcer.
c. Muscle and fat cannot regenerate.
d. Weight reduction is recommended to help prevent pressure ulcers.
C
Because subcutaneous tissues such as muscle and fat are not regenerated but simply replaced by granular tissue, the staging of pressure ulcers is never reversed. Stasis ulcers are the result of the leakage of blood from veins beneath the skin. Pressure ulcers are caused when perfusion to the tissue is impaired by external pressure that causes tissue injury and death. Sufficient nutrition is essential in maintaining skin integrity.
