The nurse is performing tracheostomy care for a client when a code blue is called for another client on the unit who experiences a cardiopulmonary arrest. Which action should the nurse take?

A. Respond to the code: Leaving during an ongoing sterile tracheostomy procedure may place the current client at risk for infection or airway compromise; the nurse must ensure the client's safety before leaving. B. Call for an assistant: The most appropriate action is to call another staff member to respond to the code while the nurse safely completes the critical procedure on the current client, maintaining both clients' safety. C. Finish the procedure: While completing the procedure is important, doing so without calling for assistance neglects the emergency response needed for the client in cardiopulmonary arrest. D. Close the room door: Closing the door offers privacy but does not address the need for immediate support in responding to the code or ensuring patient safety during the procedure.
