the foot infection could or could not be the cause of his fever but the meds for the foot infx will not change whether there is a fever or not. the foot infx will get abx w/ or w/out an infx. after treating the foot infx by cultue and rxing abx, dependibg on the symptoms and where the pod is practicing the patient may be referred to the ER, admitted to the hospital or referred to a PCP or ID. if the patient has an open wound and infx and fever (systemic signs of infx) I would most likely admit the patient to the hospital and consult ID, schedule an IandD. You can rx for the other symptoms but you will not be an expert in those meds and may not help the situation.
so now you may be asking your self why would the patient come to a pod? becuase the PCP and maybe even the ID might not know which abx are best for foot infx.
