What is an essential action for the nurse to take when first caring for a patient who has tuberculosis (TB) and is on a respirator?

The essential action for the nurse to take when first caring for a patient who has tuberculosis (TB) and is on a respirator is to perform a fit test to ensure the proper type and size of the mask for the patient. This is critical because patients with TB are infectious, and ensuring that the mask fits properly helps to prevent the spread of the bacteria to healthcare workers and other patients.

A proper fit of the mask helps to create a seal that reduces the risk of airborne transmission. It ensures that any potential pathogens are contained and do not escape into the environment, thereby protecting both the patient and the healthcare team. In settings where patients have airborne infections like TB, ensuring the correct personal protective equipment is used effectively is vital for infection control.

While securing a private room for the patient is important for controlling TB transmission, it is typically one of the initial steps taken with patients who have an airborne infectious disease but does not directly address the immediate need for effective respiratory protection. Instructing a patient on coughing etiquette is also significant for minimizing the spread of infection, but it is not the first action a nurse should take when caring for a patient on a respirator. Limiting the use of oxygen therapy does not directly relate to the prevention of infection transmission from
