The nurse is providing discharge teaching for a client diagnosed and treated for tuberculosis (TB). Which statement by the client indicates that teaching has been effective? Select all that apply.

Tuberculosis is a communicable disease, and the nurse must teach the client measures to prevent its spread. Any close contacts with the client must be tested and treated if the results of the screening test are positive. Because it is an airborne disease, the client must properly dispose of used tissues and needs to cover the mouth when coughing. There is no evidence to suggest that sterilizing dishes would break the chain of infection with pulmonary TB. It is not necessary for the client to isolate herself or himself to the house. Once the client is treated and results of three sputum cultures are negative, the client will not spread the infection.
