A nurse is caring for a client who is receiving a continuous IV infusion via an infusion pump that is malfunctioning. Which of the following actions should the nurse take?

A. Notify the housekeeping department: Housekeeping is not the appropriate department to address a malfunctioning infusion pump. The nurse should take immediate action to address the malfunction, such as replacing the pump. B. Replace the infusion pump: If the infusion pump is malfunctioning, the nurse should replace it with a functional one to ensure that the client's infusion continues safely. This is the most appropriate and immediate action to take in response to a malfunction. C. Check the expiration date on the safety inspection sticker: While it is important to ensure equipment is regularly inspected, checking the expiration date on the safety inspection sticker does not address an immediate malfunction. The priority should be replacing the pump to prevent disruption of the IV infusion. D. Plug the infusion pump into a grounded outlet: While ensuring that the pump is plugged into a grounded outlet is important for electrical safety, this does not directly resolve the issue if the pump itself is malfunctioning.
