Discussion Board Post #4

Mrs. J. is a 66 yrs. old woman with diabetes mellitus.  She presents with an oozing erythematous area on her left lower leg that began 2 weeks ago as an insect bite.  The area was itchy but not painful-until recently it is becoming more painful.  She has had an intermittent, low-grade fever for the past week but otherwise feels well.  She states the redness has gotten worse and the lesion is oozing purulent fluid approx. one week ago. Also noted mild swelling in her lower leg near the lesion and erythema tracking.  Her medication is insulin and lisinopril and she has no allergies.

what drug therapy (for the infection) would you prescribe for this patient ?

how long?

why?
