Use the following passage to answer questions 22, 23, 24, and 25.
The human body can tolerate only a small range of temperature,
especially when the person is engaged in vigorous activity. Heat
reactions usually occur when large amounts of water and/or salt are
lost through excessive sweating following strenuous exercise. When
the body becomes overheated and cannot eliminate this excess heat,
heat exhaustion and heat stroke are possible.
Heat exhaustion is generally characterized by clammy skin,
fatigue, nausea, dizziness, profuse perspiration, and sometimes fainting, resulting from an inadequate intake of water and the loss of fluids. First aid treatment for this condition includes having the victim
lie down, raising the feet 8 to 12 inches, applying cool, wet cloths to
the skin, and giving the victim sips of salt water (1 teaspoon per glass,
half a glass every 15 minutes) over a 1-hour period.
Heat stroke is much more serious; it is an immediate life-threatening situation. The characteristics of heat stroke are a high body
temperature (which may reach 106° F or more); a rapid pulse; hot,
dry skin; and a blocked sweating mechanism. Victims of this condition may be unconscious, and first-aid measures should be directed
at quickly cooling the body. The victim should be placed in a tub
of cold water or repeatedly sponged with cool water until his or her
temperature is sufficiently lowered. Fans or air conditioners will also
help with the cooling process. Care should be taken, however, not to
over-chill the victim once the temperature is below 102° F.
22. The most immediate concern of a person tending to a victim of
heat stroke should be to:
А) get salt into the victim’s body.
B) raise the victim’s feet.
C) lower the victim’s pulse.
D) lower the victim’s temperature.
