  4. Inform the client that when the results of three sputum cultures are negative, the client is not considered infectious.
Explanation
Answer: B - The client is not instructed to initiate respiratory isolation at home. This is not necessary because family members already have been exposed to the causative agent. The other options are correct. The client is also instructed to wash hands thoroughly, to cover the mouth and nose when sneezing or coughing, and to get a sputum culture every two to four weeks.
