What should Benjamin do after obtaining consent and providing care for a potentially life-threatening injury?

After obtaining consent and providing care for a potentially life-threatening injury, the most appropriate action is to continue checking the victim. This involves monitoring their condition for any changes, assessing vital signs, and ensuring that they are stable while waiting for emergency medical services (EMS) to arrive. Ongoing assessment is crucial because the situation can evolve; the victim's condition might deteriorate, requiring additional interventions or adjustments to the care being provided. Staying engaged with the victim allows for timely responses to any emerging issues, such as changes in breathing or consciousness.

The other choices would not be suitable as they either neglect the ongoing need for assessment or potentially delay necessary care. For example, placing the victim in the recovery position could be appropriate if they are unconscious and breathing but may not be suitable for a seriously injured person where ongoing evaluation is prioritized. Similarly, waiting without intervening or transporting the victim without proper evaluation could lead to adverse consequences if the victim's condition worsens. Therefore, continuing to check the victim aligns with best practices for maintaining safety and providing effective care until professional help arrives.
