What should be the nurse's immediate action when a patient suddenly becomes unresponsive?

When a patient suddenly becomes unresponsive, the priority is to ensure the patient's safety and to respond quickly to prevent any potential deterioration in their condition. Calling for help and initiating CPR if necessary is the appropriate immediate action. This response recognizes the possibility of a life-threatening situation, such as cardiac arrest or severe respiratory distress, where time is critical.

Initiating CPR can be lifesaving, as it provides circulation and oxygenation to vital organs until advanced medical help arrives. Simultaneously, calling for assistance ensures that additional help is on the way, which can be crucial in managing the situation effectively.

Other actions, while important, do not take precedence at this immediate moment. Checking vital signs or looking for medication errors can be performed once the patient's safety is assured and immediate support is underway. Notifying the patient's family, though important for emotional support and information, is not an immediate action in the face of a potential medical emergency. Prioritizing actions that preserve life and stabilize the patient is essential in nursing practice.
