When must a TB test be performed on facility staff?

The correct choice states that a TB test must be performed on facility staff no more than one year prior to employment or within seven days after employment begins. This requirement is in place to ensure that staff members are not carriers of tuberculosis and to maintain a safe and healthy environment for both residents and other staff.

Having the test done up to one year before employment allows the facility to confirm the staff's health status effectively while also ensuring that recent staff members are tested quickly after they begin their roles to prevent any possible outbreaks. This timing is critical in settings such as adult residential facilities, where individuals may have compromised immune systems or other health vulnerabilities.

Other options either extend the time frame beyond what is typically required or do not prioritize immediate testing post-hiring, which could delay addressing potential health risks associated with tuberculosis in the facility. Ensuring that a TB test is done either before or immediately after employment is crucial for compliance with health regulations and the overall safety of everyone in the facility.
