The nurse is admitting a patient with tuberculosis who is coughing. To minimize the transmission of tuberculosis, which nursing measure is most appropriate?
A) Wearing a high-efficiency particulate air (HEPA) mask when entering the patient's room
B) Wearing gloves and a mask when entering the patient's room
C) Restricting visitors until the patient has taken antitubercular medications for 2 weeks
D) Placing the patient in a room with open windows
Ans: A
Feedback: Because the patient is coughing and tubercle bacilli are transmitted via airborne droplets, a HEPA mask is necessary to prevent transmission. Gloves aren't necessary unless the nurse is touching contaminated items such as respiratory equipment. There's no need to restrict visitors, as long as they comply with isolation procedures. A room with reverse flow ventilation also reduces transmission.
