A patient being treated for a stage 3 pressure ulcer is demonstrating delayed healing. What information in the patient's medical record and history would explain this delay?
Select all that apply.
1. The patient had total knee replacement 7 years ago.
2. The patient takes insulin for control of type 2 diabetes mellitus.
3. The patient was diagnosed with peripheral vascular disease 5 years ago.
4. The patient was prescribed steroids for treatment of chronic lung condition.
5. The patient takes acetaminophen 650 mg twice a day for arthritis pain.
Correct Answer: 2, 3, 4
Chronic diseases may impair healing. High blood glucose levels impair chemotactic and phagocytic function. Arterial and venous disorders impair the delivery of oxygen and nutrients to heal tissues and remove toxins, bacteria, and other waste products from the wound area. Drug therapy with corticosteroids may suppress the immune and inflammatory responses and delay healing. A history of total knee replacement would not delay healing in this patient. Acetaminophen is not identified as a medication that adversely affects healing.
