The nurse is working on an infectious disease unit. Which client should be assigned to a room with negative airflow, while requiring personnel to use a particulate respirator mask, and requiring staff to observe airborne, as well as standard precautions?

A. A client with a positive Mantoux test and positive sputum cultures for acid-fast bacillus (AFB) indicates tuberculosis (TB), which requires airborne precautions due to its highly contagious nature. Negative airflow rooms are essential for preventing the spread of TB. B. Herpes simplex II is transmitted through direct contact and does not require airborne precautions; standard precautions are sufficient. C. Scarlet fever, while contagious, requires droplet precautions and not airborne precautions, so a negative airflow room is not necessary for these clients. D. Scabies is transmitted through direct contact and requires contact precautions rather than airborne precautions.
