A nurse is caring for a client who has active tuberculosis (TB). Which of the following actions should the nurse plan to take to prevent the transmission of the disease?

A. Droplet: Correct. Pneumonia is transmitted by respiratory droplets that are generated by coughing, sneezing, or talking. The nurse should wear a surgical mask and eye protection when caring for the client and maintain a distance of at least 3 feet from the client.

B. Airborne: Incorrect. Airborne precautions are used for diseases that are transmitted by small particles that remain suspended in the air for long periods of time, such as tuberculosis, measles, or chickenpox. The nurse should wear a respirator and place the client in a negative-pressure room.

C. Contact: Incorrect. Contact precautions are used for diseases that are transmitted by direct or indirect contact with the client or the client's environment, such as Clostridium difficile, scabies, or MRSA. The nurse should wear gloves and a gown and use dedicated equipment for the client.

D. Protective environment: Incorrect. Protective environment precautions are used for clients who are immunocompromised and at risk of infection from others, such as clients who have had a stem cell transplant or are receiving chemotherapy. The nurse should wear a mask, gloves, and a gown and place the client in a positive-pressure room with HEPA filtration.

A. A client who has cellulitis and is receiving oral antibiotics every 8 hr has a mild to moderate infection that can be managed at home with proper wound care and medication adherence. The client does not require hospitalization unless there are signs of systemic infection or complications.

B. A client who is postoperative following an upper endoscopy procedure and is alert but does not have a gag reflex has a high risk of aspiration and airway obstruction due to impaired swallowing function. The client requires close monitoring and intervention until the gag reflex returns, which can take several hours or longer depending on the type and amount of anesthesia used.

C. A mother and their newborn 12 hr postdelivery have not completed the minimum recommended stay of 24 to 48 hours for uncomplicated vaginal deliveries or 72 to 96 hours for cesarean deliveries, according to the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists. The mother and their newborn require assessment, education, support, and follow-up care to ensure their health and well-being.

D. A client who has lower extremity weakness and is newly admitted for observation has an undiagnosed condition that could indicate a serious neurological or vascular problem, such as stroke, spinal cord injury, or peripheral artery disease. The client requires diagnostic testing, evaluation, treatment, and rehabilitation to prevent further deterioration or complications.
