Under what circumstances can non-pathogenic organisms become disease producing?

You are treating a patient with a deep partial-thickness burn wound involving 15% total body surface area with irrigation, debridement, and silver sulfadiazine–impregnated gauze dressings. You notice an increase in erythema, more purulent drainage, and that the previously red granulation tissue is now pale. What is the most logical reason for this occurrence?

A. The zone of coagulation is resolving. B. The patient has an allergy to sulfa. C. The wound is infected. D. You should be less aggressive with your debridement because this is a sign of a hyperactive inflammatory response.

Endorphins and enkephalins are examples of:

A. anesthetics B. antipyretics C. neurotransmitters D. analgesics
