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?

Choice A reason: This is the most immediate and important action to take to prevent the potential spread of COVID-19, especially in a healthcare setting where there is a risk of infecting others. Choice B reason: While placing the swab in a biohazard bag is a standard procedure, it is not as critical as isolating the patient to prevent transmission. Choice C reason: Assisting the client to recall contacts is important for contact tracing, but it is secondary to immediate infection control measures within the clinic. Choice D reason: Educating the client on preventive measures is important, but it does not take precedence over immediate actions to prevent the spread of infection in the clinic.
