Two weeks after returning home from traveling, a client presents to the clinic with conjunctivitis and describes a recent loss in the ability to taste and smell. The nurse obtains a nasal swab to test for COVID-19. Which action is most important for the nurse to take?

A. Assisting the client to recall everyone possibly exposed since the onset of symptoms is important for contact tracing but is not the most immediate action to take. B. Teaching the client to wear a mask, hand wash, and social distance to prevent spreading the virus is important for infection control but does not address the immediate need to prevent potential transmission to others in the clinic setting. C. Placing the nasal swab specimen for COVID-19 directly into a biohazard bag is appropriate for specimen handling but does not address the need for immediate infection control measures for the client and others in the clinic setting. D. Moving the client to a private room, keeping the door closed, and initiating droplet precautions is the most important action to take to prevent potential transmission of COVID-19 to others in the clinic setting, given the client's symptoms and recent travel history.
