Four days after exposure to the coronavirus (COVID-19), a client has a negative COVID-19 test result. Eight days after the negative test result, the client presents with fever, fatigue, and cough, and the nurse performs a second COVID-19 test. Which action is most important for the nurse to take?

Notify the charge nurse the client will need assignment to the COVID-19 specified area of the facility.

Institute droplet precautions, place the client in a private room, and keep the door closed.

Explain to the client to inform others that they may have been potentially exposed in the last 14 days.

Place the nasal swab specimen for COVID-19 directly into a biohazard bag.
