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?

Choice A rationale A client with a positive Mantoux test and sputum cultures positive for acid-fast bacillus (AFB) requires a negative airflow room and airborne precautions. This is to prevent the spread of tuberculosis (TB), an infectious disease that can be transmitted through airborne particles. The use of a particulate respirator mask by healthcare personnel is essential in protecting themselves from inhaling infectious aerosols. Implementing these precautions is critical in controlling the spread of TB within healthcare settings and ensuring patient and staff safety. Choice B rationale A client with genital herpes simplex II lesions does not require a negative airflow room or airborne precautions. Herpes simplex virus (HSV) is primarily transmitted through direct contact with infected lesions or body fluids. Standard precautions, including contact precautions when dealing with lesions, are adequate to prevent the spread of HSV. Negative airflow rooms and airborne precautions are not necessary for managing this condition. Choice C rationale Scarlet fever, complicated with pneumonia, primarily requires standard and droplet precautions rather than airborne precautions. Scarlet fever is caused by group A Streptococcus, which is spread through respiratory droplets. While pneumonia can increase the severity of the infection, negative airflow rooms and particulate respirators are not typically required. Droplet precautions, such as wearing masks and maintaining distance, are sufficient to prevent transmission. Choice D rationale Scabies is a parasitic infestation that spreads through direct skin-to-skin contact or contact with contaminated items such as bedding and clothing. Negative airflow rooms and airborne precautions are not necessary for managing scabies. Standard and contact precautions, including wearing gloves and gowns and thoroughly cleaning and disinfecting contaminated items, are adequate to prevent the spread of the mites causing scabies. The use of a particulate respirator mask is not required.
