Which of the following scenarios would likely require a tuberculosis skin test?

The scenario involving a new job in a hospital setting is likely to require a tuberculosis skin test due to the higher risk of exposure to infectious diseases in healthcare environments. Hospitals often require their employees, especially those who will be in direct contact with patients or in settings where there may be a higher prevalence of tuberculosis, to undergo screening. This is part of standard infection control protocols to protect both the healthcare workers and the patients they serve.

In contrast, while other professions may have some level of risk regarding tuberculosis, they typically do not involve the same level of direct exposure associated with a healthcare setting. Employees in banks, gym instructors, and food service workers generally do not engage with individuals who might present active tuberculosis, making the necessity for routine screening less compelling in those contexts. Hence, the requirement for a tuberculosis skin test is primarily dictated by the risk involved in the work environment.
