Measles is ahighly contagious airborne disease, and thebest immediate actionin an outpatient clinicwithout an Airborne Infection Isolation Room (AIIR)is tomask the patient and isolate them in a private room with the door closed.

Why the Other Options Are Incorrect?

A. Patient should be sent home– While home isolation may be necessary,sending the patient home without proper precautions increases exposure risk.

B. Staff should don a respirator, gown, and face shield– WhileN95 respiratorsare necessary for staff,this does not address patient containment.

C. Patient should be offered the MMR vaccine– Thevaccine does not treat active measles infectionand should be givenonly as post-exposure prophylaxisto susceptible contacts.
