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?

Rationale A. Herpes simplex virus type II (HSV-II) primarily spreads through direct contact with the lesions and is not airborne. Airborne precautions and negative airflow rooms are not necessary for this condition. B. Scarlet fever is caused by Group A Streptococcus bacteria and typically spreads through respiratory droplets. However, scarlet fever itself does not require airborne precautions. If complicated with pneumonia, respiratory droplets could potentially spread the infection, but specific airborne precautions are generally not required unless there are other pathogens involved that require it. C. Scabies is caused by the Sarcoptes scabiei mite and spreads through direct skin-to-skin contact. It does not require airborne precautions or negative airflow rooms. D. A positive Mantoux test and sputum cultures positive for acid-fast bacillus (AFB) suggest tuberculosis (TB) infection. TB is spread through airborne droplets (e.g., coughing, sneezing), and therefore, requires airborne precautions including negative airflow rooms to prevent transmission to others.A
