Final answer:
Delayed wound healing in a patient with stage III pressure ulcer can be contributed to by a low albumin level.
Step-by-step explanation:
Delayed wound healing in a patient with stage III pressure ulcer can be contributed to by an albumin level of 4g/dl. Albumin is a protein found in the blood that helps carry nutrients to the tissues, including the wound site. A low level of albumin indicates poor nutrition, which can impede the healing process. The other options, WBC of 6000, BMI of 24, and urine output 25ml/hour, do not directly contribute to delayed wound healing.
