Flashcards in #7. Environmental Considerations & Common Medical Conditions Deck (41):
1

"heat loss from a warmer object to a cooler object - indirectly"

manners of heat dissipation: radiation

2

"warmer body gives off heat to cooler objects - directly"

manners of heat dissipation: conduction

3

"cooler air blowing over body will cool off the body"

manners of heat dissipation: convection

4

"perspiration form on surface of skin and evaporates, carrying the heat with it"

manners of heat dissipation: evaporation

5

for temperatures that are less then 20 degrees Celsius, what are the primary ways to dissipate heat?

conduction and evaporation

6

for temperatures that are greater then 20 degrees Celsius, what is the primary way to dissipate heat?

evaporation

7

Etiology: when an individual abruptly stops exercising and blood pools therefore not being returned to the brain or heart.
S&S: lightheadedness or fainting
What is it?

Heat Syncope

8

"temporary loss of consciousness caused by a fall in blood pressure"

syncope

9

Management for heat syncope?

elevate legs, cool down with towels, re-hydrate, and remove from heat

10

S&S: extreme weakness, profuse sweating, light headedness, impaired ability, headaches, tachycardia, cramping, vomiting or diarrhea, and core temp greater then 39.5 degrees. What is it?

Heat Exhaustion

11

When someone has heat stroke, why do you not want submerge them in water?

A) because they can pass out and drown
B) because if their extremities get to cold to fast then it sends a rush of cold blood to the heart which is a big no no

12

Etiology: body is unable to dissipate heat and results in a core temp that is greater then 40 degrees
S&S: sudden collapse, LOC, flushed, hot skin, shallow breathing and rapid pulse
What is this?

Heat Stroke

13

Which do you call 911 for, heat exhaustion or heat stroke?

heat stroke

14

Which causes skin to feel cold, clammy and look pale, heat exhaustion or stroke?

exhaustion

15

Rapid weak pulse is heat ____ while rapid strong pulse is heat _____.

exhaustion; stroke

16

Do you sweat if you have heat stroke?

nope

17

"preventable disorder involving fluid-electrolyte balance; results in abnormally low plasma sodium concentration, and the low levels disrupt the osmotic balance across the BBB which results in a rapid influx of water into the brain causing swelling and unusual neurological responses"

exertional hyponatremia

18

S&S: confusion, seizure, coma - can lead to death because brain-stem ruptures

exertional hyponatremia

19

Hypothermia - problems arise when heat loss exceeds heat production - this results in impairment of ______ function

neuromuscular

20

Etiology: body's ability to produce heat is impaired and core temp falls to less then 35 degrees
S&S: shivering, numbness, lack of coordination, confused or unusual behavior, slurred speach
What is it?

hypothermia

21

If someone has hypothermia and starts to complain about being to hot and they start to remove clothes, what does this mean?

they are getting close to death

22

Hypothermia
-shivering occurs @ ____
-shivering stops @ ___-___ degrees
-death is imminent @ ___-___degrees

small drops in body temp
29.4-32.2
25-29

23

Why is it important not to rub skin that has frost bite?

Because fluid between the cells has crystallized and has ice crystals so if you rub it then ice shards will damage tissue and vessels

24

At risk temperatures:
Red Flag @ __-__
Amber Flag @ __-__
Green Flag @ __-__
White Flag @ less than __

23-28
18-23
10-18
less than 10

25

Increased height = reduced barometric pressure resulting in decreased partial pressure of oxygen = less saturation of ___ ___ ____

red blood cells

26

During altitude sickness, how does the body compensate?

tachycardia and hyperventilation - responses are a result of having fewer red blood cells than necessary to adequately capture available oxygen

27

What type of altitude illness: chest tightness, persistent cough, frothy sputum, feeling of suffocation during sleep

High Altitude Pulmonary Edema

28

What type of altitude illness: headache, disorientation, loss of coordination, memory loss, coma, psychotic behavior

High Altitude Cerebral Edema

29

What type of altitude illness: anorexia, nausea, vomiting, insomnia, dizziness, fatigue, lightheadedness

Acute Mountain Sickness

30

What is the #2 cause of death due to weather phenomena?

lightening

31

Diabetes: Type _ is insulin-dependent - typically occurs in individuals under age 35

I

32

Diabetes: Type _ is non-insulin dependent - occurs in all ages, becoming increasingly prevalent in younger individuals due to childhood obesity

II

33

Vigorous exercise increases peripheral insulin action and enhances ___ tolerance.

glucose

34

Extreme temperatures and unpredictable activity levels may require the administration of rapid-acting ____ for management of diabetes.

carbohydrates

35

Etiology: occurs when the body has too much insulin and too little blood sugar
S&S: tingling in mouth, hands or other parts of body, physical weakness, headaches, abdominal pain, shallow respiration, rapid HR
What is it?

Insulin Shock

36

Etiology: loss of sodium, potassium, and ketone bodies through excessive urination, put off an acetone smell (like nail polish)
