Wound healing

Here is another question from the practice exam I am doing.
"Describe what can affect wound healing and what diagnostic tools you can use to verify them."

Bad peripheral circulation can worsen the wound healing. Palpation of peripheral pulses and doppler guided blood pressure taking of the ankle. It can be falsely high in diabetic patients because of media stenosis. Then you can use toe pressure.

Infection. Could be S.aureus, pseudomonas or coliform bacteria. Wound samples could be taken to see if there is an infection.

High blood glucose level (as in poorly maintained diabetes) can be measured by HbA1c.

Penetrate the smoking habits of the patient.
