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. Moving the client to a private room, keeping the door closed, and initiating droplet precautions are important to prevent potential transmission of COVID-19, especially considering the client's symptoms and recent loss of taste and smell, which are associated with COVID-19. B. Assisting the client to recall everyone possibly exposed since onset of symptoms is relevant for contact tracing but does not address immediate infection control measures for the suspected case. C. Placing the nasal swab specimen for COVID-19 directly into a biohazard bag is a correct laboratory procedure but does not address immediate infection control measures for the suspected case. D. Teaching the client to wear a mask, hand wash, and social distance to prevent spreading the virus is important for preventing transmission, but in this scenario, immediate isolation precautions are necessary until a COVID-19 diagnosis is confirmed or ruled out.
