In the context of taking a patient's medical history for active tuberculosis, the use of a mask is essential due to the airborne nature of the disease. Tuberculosis (TB) is primarily transmitted through inhalation of droplet nuclei released into the air when an infected person coughs or sneezes. Therefore, wearing a mask helps to protect the healthcare worker from inhaling these infectious particles.

Specifically, an N95 respirator or a similar high-filtration mask is recommended because it is designed to filter out at least 95% of airborne particles, including those associated with TB. This form of personal protective equipment (PPE) is crucial in preventing the transmission of the disease during patient interactions, particularly in enclosed or poorly ventilated spaces where the risk of airborne infection is higher.

While gloves, face shields, and gowns are important in various clinical scenarios, they do not provide the necessary protection specifically against the inhalation of TB bacilli, which is why the mask is the appropriate choice in this case.
