Answer to Question 1
ANS: C
Airborne precautions have two major components: (1) placement of the infected patient in an ar-ea with appropriate air-handling and ventilation and (2) use of respiratory protective equipment by health care workers and visitors entering the patient's room. In cases in which an infected pa-tient must be transported, the patient should wear a surgical mask to minimize dispersal of drop-let nuclei. Current standards require that infected patients be placed in a private, nega-tive-pressure isolation room. Negative air pressure within the room should be monitored relative to other areas of the hospital. Severe acute respiratory syndrome, measles, chicken pox (primary varicella zoster virus), and tuberculosis are illnesses that require airborne precautions.
