During patient transport, what is a priority action in the event of a sudden change in the patient's condition?

Assessing the patient's vital signs and intervening accordingly is critical during transport when there is a sudden change in the patient's condition. This action allows the healthcare provider to quickly identify any deterioration in the patient's status, which could indicate life-threatening issues that require immediate attention. Vital signs provide essential information on the patient's respiratory, cardiac, and neurological status.

By performing an assessment, the responder can determine if the patient is in distress, monitor changes, and decide on the necessary interventions, such as administering oxygen, adjusting their position, or implementing advanced life support measures if needed. Taking these steps ensures that the patient's safety is prioritized and that appropriate care is provided during transit.

In contrast to this approach, continuing transport without intervening overlooks the potential critical changes in the patient's condition that need to be addressed. Reassuring the patient without taking any action does not provide any tangible support to their medical needs. Lastly, while contacting medical control for guidance is beneficial, it should come after an immediate assessment and intervention, as time can be crucial in emergency situations.
