Piggy is the most rational member on the island. He's intelligent, level

Before focusing your attention on any injured limb, you must "stabilize the patient's airway, breathing, and circulation.
"
Limb injuries are not life threatening except if there is unreasonable bleeding from an open injury. Therefore, it is fundamental that you initially settle the patient's airway, breathing, and course before you center around appendage damage, paying little heed to the torment or disfigurement that might be available at that damage site. As you inspect and treat patients with musculo-skeletal wounds, recall this is a terrifying and excruciating background for them. Clarify what you are doing as you lead your examination and settle the patient. Treat the patient with a similar care and consideration that you would provide for a nearby individual from your own particular family.
