Q
  1. Describe the treatment protocol for lightning injuries.
A

If the person is conscious and has normal cardio respiratory function, a secondary assessment should be conducted to determine if burns, fractures, or other trauma have been sustained. If not breathing and in cardiac arrest, EMS should be activated, and rescue breathing/CPR initiated. And less ruled-out, a cervical spine injury should be suspected. Any person struck by lightning should be immediately transported to the nearest medical facility.

Q
  1. Identify five strategies for reducing the risk of cold related injuries during physical activity participation.
A
  • Check weather conditions in consider possible deterioration
  • Identify individuals who may be susceptible to cold in observe closely
  • Dress in several layers where windproof dry well insulated clothing that allows water evaporation such as wool
  • Wear well insulated footwear to keep the feet dry
  • Wear insulated waterproof mittens, gloves hats, and scarves
  • Avoid dehydration
  • Do not drink alcoholic beverages or eat snow because this worsens hypothermia
  • Carry nutritional snacks that contain predominantly carbohydrates
  • Eat small amounts of food frequently
  • Do not stand in one position for an extended period
  • Breathe through your nose rather than your mouth to minimize heat and fluid loss
  • Watch your face and ears and fingers for signs of frostbite
