How can a makeshift splint be created in an emergency situation to provide temporary support for a broken or injured limb?

To create a makeshift splint in an emergency situation for a broken or injured limb, you can use materials like sticks, cardboard, or rolled-up magazines. Place the splint along the injured limb and secure it with bandages or cloth strips. Make sure the splint is long enough to immobilize the joint above and below the injury. This will help provide temporary support and prevent further damage until professional medical help can be obtained.
