A 60 year old woman presents with a complicated wound to her left calf. Throughout the
assessment you gather information from the patient and find out the patient is currently
smoking. What information would you give to the patient in regards to her current
smoking habits and her complicated wound?
a. You can continue to smoke even with your current wound because it will not effect
the healing process in any way.

disease and cardiovascular disease as well. - -b. Smoking during the healing process
can cause vasoconstriction therefore causing ischemia and interrupt the healing
