You are the first person to arrive at a secured accident scene where a motorcyclist is lying motionless on their back. They are wearing a full-face helmet with the visor closed. You notice a large piece of debris embedded deeply in their lower leg, which is bleeding heavily. Following the DR ABC protocol and standard DVSA first aid guidelines, which sequence of actions is correct?
- ACarefully support the casualty's neck while another person removes the helmet so you can fully assess the airway. Once clear, pull out the embedded debris and apply direct pressure over the wound to stop the bleeding.
- BImmediately remove the helmet to check for head injuries and establish breathing. To treat for shock, elevate the casualty's legs, and offer them a small sip of water while waiting for emergency services to arrive.
- Open the helmet visor to check their airway and breathing, leaving the helmet on. Manage the bleeding by applying pressure on either side of the embedded object without removing it, and do not move the casualty.Cevap
- DRoll the casualty into the recovery position to protect their airway, remove their helmet to monitor their breathing closely, and apply a tight bandage directly over the embedded object to stem the blood flow.
Cevap
Open the helmet visor to check their airway and breathing, leaving the helmet on. Manage the bleeding by applying pressure on either side of the embedded object without removing it, and do not move the casualty.
The correct sequence prioritizes checking the airway by simply opening the visor, which avoids the high risk of exacerbating a spinal injury by removing the helmet. It also correctly dictates leaving the embedded object in place and applying pressure around it, as removing it can cause rapid blood loss and further tissue damage. Finally, it correctly advises against moving the casualty when they are not in immediate environmental danger.
