Quizplus · Accepted Answer

A petechial rash is a sign of a serious adverse reaction to TMP-SMX, such as thrombocytopenia. The nurse should hold the medication and notify the provider immediately. Blood glucose level, BUN and creatinine level, and diphenhydramine are not directly relevant to this situation.
