A nurse on a medical-surgical unit is caring for a client and assesses the following: Exhibits What action by the nurse is best?

A. Transfer the client to the Intensive Care Unit.: While ICU transfer may eventually be necessary for a deteriorating patient, the decision requires rapid bedside assessment and stabilization first. Immediate action is required before transfer decisions can safely be made. B. Continue monitoring every 30 minutes.: The client exhibits signs of hemodynamic instability, including hypotension (BP 92/78 mmHg), tachycardia (136 bpm), bradypnea (RR 10/min), fever, and altered mental status (responds to voice). Waiting and monitoring without intervention risks further deterioration and delayed treatment. C. Notify the unit charge nurse immediately.: Informing the charge nurse is appropriate, but rapid escalation to a team trained to manage acute patient deterioration is more urgent. Delays may compromise patient safety in a time-sensitive situation. D. Call the Rapid Response Team.: The client meets multiple criteria for acute clinical deterioration, including hypotension, tachycardia, altered mental status, fever, and respiratory compromise. Activating the Rapid Response Team ensures immediate expert assessment and intervention to stabilize the patient, address potential sepsis, and prevent progression to shock or cardiac arrest.
