“Measles and adenovirus require airborne precautions.”
“Barrier protection requires a private room for the client.”
“Droplet precautions are used for clients with meningitis.”
“Contact precautions are used for clients with disseminated varicella zoster.”
Number 3 is correct.
Rationale: Droplet precautions, along with standard precautions, are used with clients infected with meningitis. Measles requires airborne precautions, while adenovirus requires droplet precautions. Barrier protection calls for either a private room or a cohort client with the same infection. Disseminated varicella zoster requires airborne precautions.
