Question 11

11. Describe the treatment protocol for lightning injuries.

Answer 11

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.

Question 12

12. Identify five strategies for reducing the risk of cold related injuries during physical activity participation.

Answer 12

• 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
