During transport of a burn patient, what is absolutely contraindicated to touch your patient?

A 70-year-old homeless man presents with a rash to his hands, wrists, and ankles. He denies any known allergies and states that the rash itches severely at night. His vital signs are stable, and he is breathing without difficulty. You should:

A) transport him to the hospital and thoroughly wash your hands after patient care has been completed. B) establish vascular access in case he begins to experience signs and symptoms of a severe allergic reaction. C) be highly suspicious that he has body lice and use a high-level disinfectant when cleaning the ambulance. D) administer 25 mg of diphenhydramine IM and transport him to an appropriate medical facility.

P.o. means:

after meals nothing by mouth as needed by mouth
