25
hyperthermia?
A condition in which the body core temperature rises to 101 degrees F (38.3C) or more?
26
A condition in which the body core temperature falls below 95 degrees F (35C) ?
hypothermia
27
hypothermia?
A condition in which the body core temperature falls below 95 degrees F (35C) ?
28
The transfer of heat to colder objects in the environment by radiant energy; for example, heat gain from a fire.
radiation.
29
The inhaling and exhaling of air; the physiologic process that exchanges carbon dioxide from fresh air?
respiration.
30
respiration?
The inhaling and exhaling of air; the physiologic process that exchanges carbon dioxide from fresh air?
31
What is reverse triage? When is it used primarily?
Reverse triage is when efforts are focused on those who are in respiratory and cardiac arrest. Used in the case of multiple victims of a lightning strike.
32
The ability of the skin to resist deformation; tested by gently pinching skin on the forehead or back of the hand?
turgor.
33
Three causes of a local cold injury?
frostbite, frostnip, and immersion foot.
34
Why should you not attempt to rewarm patients who have moderate to severe hypothermia?
Because they are susceptible to the development of dysrhythmias.
35
What is the key to treating patients with hypothermia?
The key is to stabilize vital functions and prevent further heat loss.
36
What are the three forms of heat emergency?
Heat cramps. Heat exhaustion. Heat stroke.
37
Which heat emergency is a form of hypovolemic shock caused by dehydration?
heat exhaustion.
38
What are the four factors that affect how a person deals with exposure to a hot or cold environment?
Physical condition. Age. Nutrition and Hydration. Environmental Conditions.
39
At what age do humans develop the ability to thermoregulate their body via shivering?
12-18 months.
40
What does the body do to prevent heat loss that causes blue lips and/or fingertips?
constricts blood vessels in the skin.
41
How do you assess the patient's core body temperature (CBT) when concerned about hypothermia?
Pull back on your glove and place the back of your hand on the patient's skin at the abdomen.
42
What is the temp of mild hypothermia and what are the signs and symptoms?
95-93F. Shivering. Foot stamping.
43
What is the temp and cardio respiratory response to mild hypothermia?
95F-93F. Constricted blood vessels. Rapid breathing.
44
What is the temp and level of consciousness in mild hypothermia?
95F-93F. Withdrawn.
45
What is the temp and signs and symptoms of moderate-mild hypothermia?
92F-89F. Loss of coordination. Muscle stiffness.
46
What is the temp and cardio respiratory response to moderate-mild hypothermia?
92F-89F. Slowing respiration's. Slow pulse.
47
h
92F-89F. Confused. Lethargic. Sleepy.
48
What is the temp and signs and symptoms of moderate-severe hypothermia?
88F-80F. Coma.
49
What is the temp and cardio respiratory response to moderate-severe hypothermia?
88F-80F. Weak pulse. Dysrhythmias. Very slow respirations.
50
What is the temp and level of consciousness in moderate-severe hypothermia?
88F-80F. Unresponsive.
51
What is the temp and signs and symptoms of severe hypothermia?
Less than 80F. Apparent Death.
52
What is the temp and cardio respiratory response to severe hypothermia?
Less than 80F. Cardiac arrest.
53
What is the temp and level of consciousness in severe hypothermia?
Less than 80F. Unresponsive.
54
A common saying when treating anyone but specifically when treating people with hypothermia. No one is dead unless they are ______ and _______.
warm. dead.
