Therm Eval Flashcards
What is the hallmark of heat exhaustion?
Hypovolemia (abnormal loss of circulating blood plasma)
T/F: With environmental temperatures > 95F (35C) all heat loss is through evaporation.
TRUE
What is the hallmark of heat stroke?
Hyperthermia (max hyperthermia = core temp > 105 may still be sweating)
The best tool to determine heat stress from the environment is the:
WBGT (Wet Bulb Globe Thermometer)
T/F: Thirst is a good indicator to identify dehydration.
False (can lose 1.5L water before perceiving thirst)
T/F: Hypothermia cases requiring hospitalization only occur in the northern states.
FALSE
You and group of chiropractors are hiking in the mountains when one falls into a stream and becomes hypothermic. Which of the following is the correct treatment: undress near buff and crawl into a sleeping bag with them, build a fire, call for a helicopter, make a warm cup of coffe or introduce other heated fluids.
Undress near buff and crawl into a sleeping bag with them
T/F: Frotsbite should be rubbed with snow to stimulate the superficial circulation.
FALSE
Frostbite is first seen as
White spots
The single most useful sign for recognizing the progression of acute mountain sickness is
ataxia
Temperature is regulated by the
hypothalamus
Which of the following is NOT a sign or symptom of an exertional heat related syndrome: increased heart rate, increased blood preassure, dizziness, emotional lability, all of the above
all the above
One of the hallmark signs of heat stroke is core body temperature. At what temperature is the diagnosis of heat stroke made?
104 (1 less than max)
T/F: Hypothermia can occur in any climate zone where wind and moisture can penetrate to the body.
TRUE
T/F:Patients with serious hypothermia must be handled gently. This is because they may go into cardiac arrest.
TRUE
T/F: Red patches of skin are the first signs of frostbite
FALSE
T/F: Swinging the arms around in a circle like a helicopter will help speed up re-warming (frostbite).
TRUE
T/F: Concerning the treatment of frostbite, the tissues should be warmed only when it is reasonable to expect they will not become hypothermic again (wait to heat until you know they will stay warm).
TRUE
T/F: Concerning the treatment of frostbite, during rewarming, the frozen part may become very painful
TRUE
T/F: Concerning frostbite, common locations are the nose, ears, cheeks, fingertips and the tips of the penis.
TRUE
While hiking through the mountians of Iowa with an older but really fun DC, you note he has become victim of acute mountain sickness. Which of the following is the correct form of treatment? Run for help, give the doctor a swig from your flask, carefully make a tent and place the doctor into the tent, stop the ascent and allow for acclimatization by staying at the same altitude while never leaving the doctors side.
Stop the ascent and allow for acclimatization by staying at the same altitude. Never leaving the doctors side.
The loss of _____ primarily leads to muscle cramps. (hint: an electrolyte)
Sodium
T/F: Muscle cramps can serve as a warning to a more serious impending heat exhaustion or heat stroke.
TRUE
Which of the following most closely represents the number of days you need to exercise in the heat to become acclimatized? 10, 20, 30, 5?
10
