Which type of room typically requires a negative pressure environment?

A negative pressure environment is typically used in settings where it is crucial to contain airborne pathogens or contaminants within a specific area to protect patients and staff. In the context of the options provided, nuclear medicine hot labs are designed to handle radioactive materials safely. These labs require a negative pressure setup to ensure that any potential leakage of radioactive particles or gases does not escape into the general hospital environment. The use of negative pressure helps to maintain safety for both the staff working in the lab and for other patients in the hospital.

In contrast, rooms for immune-compromised patients usually operate under positive pressure to protect them from outside contaminants, while newborn intensive care rooms focus on creating a controlled and stable environment, necessitating different airflow concerns. Surgical suites also typically maintain a different pressure environment to minimize the risk of infection during procedures. Thus, in the context of safety protocols specific to handling radioactive materials, a negative pressure environment is essential for nuclear medicine hot labs.
