Short Answer

11. Conduction, convection, evaporation, and radiation

12. Relative humidity and wind velocity

13. Cold drinks

14. Overweight individuals, women, individuals with poor fitness level, history of heat illness, or have a fever. 

15. Clinically, the victim of heat exhaustion will collapse and manifest profuse sweating, flushed skin, mildly elevated temperature, dizziness, hyperventilation, and a rapid pulse.

16. Immediate treatment of heat exhaustion requires ingestion of fluid and eventual IV fluid replacement of large quantities of water. The athlete should also be placed in a cool environment.

17. Clinically, it is characterized by sudden collapse with loss of consciousness, flushed, hot skin with less sweating, and most important, a core temperature of 106¬ƒ or higher.

18. Care includes stripping the athlete of clothing and cooling with a fan while using a sponge to apply cool water.  Transport to the hospital as quickly as possible, do not wait for the ambulance. 

19. Sixty-five percent is lost through radiation, especially at the head and neck; 20% is lost through evaporation, of which two thirds is through the skin and one third in through the respiratory tract.

20. Superficial involves only the skin and subcutaneous tissue.  Deep is a serious injury indicating tissues that are frozen and is a medical emergency.

Rapid rewarming is required, including hot drinks, heating pads, or hot water bottles that are 100 degrees F to 110F. Transport to the hospital.

Sunlight acts on a combination of oxygen, nitrogen oxide and hydrocarbon.

23. May experience shortness of breath, coughing, chest tightness, pain during deep breathing, nausea, eye irritation, fatigue, lung irritation, and a low resistance to lung infections.

24. Asthmatics

Listing

25-30.Any of the following:

      Gradual acclimatization

      Identifying susceptible individuals

      Fluid replacement

      Temperature/humidity readings

      Change uniforms

      Keep weight records

      Eat well-balanced diet

31. Acute mountain sickness

32. Pulmonary edema

33. Sickle cell trait

34. Depart well rested

35. Pre-adjust if possible

36. Drink plenty of fluids

37. Avoid caffeine if traveling east

38. Avoid use of alcohol

39. Train later if traveling west and earlier if traveling east

Essay

40-43.In high altitudes, there is a decrease in maximum oxygen uptake. This loss in oxygen uptake represents a deterioration in an athlete's performance in endurance events, depending on the duration of effort and lack of wind resistance. Often, the athlete's body compensates for this decrease in maximum oxygen uptake with corresponding tachycardia. When the body is suddenly without its usual oxygen supply, hyperventilation can occur. Many of these responses are results of having fewer red blood cells than necessary to adequately capture the available oxygen in the air.
