How often should a rescuer check the responsiveness of a patient while waiting for EMS?

A rescuer should check the responsiveness of a patient continually while waiting for Emergency Medical Services (EMS) to arrive. This practice is crucial for several reasons.

Firstly, a patient's condition can change rapidly, and ongoing assessments allow the rescuer to identify any deterioration or improvement in responsiveness. By checking continually, the rescuer can provide immediate interventions if the patient shows signs of distress or if their level of consciousness fluctuates.

Additionally, continual checks ensure that the rescuer can communicate vital information to EMS, such as changes in the patient's condition, which is essential for effective medical intervention upon their arrival. This proactive approach not only prioritizes the patient's safety but also ensures that the rescuer is fully engaged and observant during this critical waiting period.

Other options may suggest less frequent checks, which could result in missing important changes in responsiveness that could impact the patient's outcome. Therefore, the emphasis on continual monitoring is fundamental in emergency response situations.
