Rationale:A. Placing a client with active tuberculosis in a room with another client increases the risk of airborne transmission of the infection, which is inappropriate for infection control.B. A room with air exhaust directly to the outdoor environment is ideal for a client with active tuberculosis because it provides negative pressure, helping to contain and prevent the spread of the infectious airborne particles.C. The ICU is typically reserved for critically ill patients requiring intensive monitoring and care, and it may not provide the necessary infection control measures for TB.D. A room near the nurses' station would not ensure the negative pressure ventilation needed to prevent airborne transmission of tuberculosis.
