Q

basic principle of heat transfer

A

Heat transfer happens from point of higher temperature to a point of lower temperature. Transfer only stops when both temperatures have equalized.

16
Q

Results from a failure of the thermoregulatory center

and suppression of sweating

A

HEAT STROKE

17
Q

cardinal signs of heat stroke

A

Rapidly rising temperature (41-43°C)
Hot and dry skin- main difference from heat
exhaustion
Brain dysfunction (delirium, convulsions, coma, can even lead to death

18
Q

treatment for heat stroke

A

decrease deep body temperature
Submerge in ice water ideally, but this can cause shivering. Spraying ice cold water is
more efficient with fanning; remove person from warm environment

19
Q

Results from a deficiency of water or salt or both leading to circulatory insufficiency

A

HEAT EXHAUSTION

20
Q

Usually in unacclimatized persons with inadequate salt and water replacement

A

HEAT EXHAUSTION

21
Q

Fainting in unacclimatized workers standing erect and is due to pooling of blood in the peripheral areas of the
body in an attempt to dissipate excess heat.

A

heat syncope

22
Q

cardinal manifestation of heat syncope

A

Giddiness and fainting upon prolonged standing or sudden changes in posture

23
Q

Due to excessive sweating with high water intake but inadequate salt intake

A

heat cramps

24
Q

cardinal manifestation of heat cramps

A

Painful muscle spasms usually involving the arms, legs, abdomen

25
Q

Vesiculopapular erythematous rashes at the

shoulder/back. Commonly seen in children

A

heat rash

26
Q

A core temperature of 35 ° C / 95 ° F or lower

A

hypothermia

27
Q

reddened nose and ears

A

frostnip

28
Q

Due to prolonged exposure to nonfreezing temperatures usually less than 10 ° C

A

Trench foot or immersion foot

29
Q

Due to freezing and formation of ice crystals within

the tissues and is primarily a vascular problem

A

frostbite

30
Q

subjective undesirable part of sound

A

noise

31
Q

Audible range is between

A

20-20000

32
Q

Speech frequency

A

500-2000

33
Q 
subjective sensation of pain in ears at the time of exposure, usually conductive
hearing loss (not permanent)
A

Acute rupture of the tympanum

34
Q

Occurs when a person who is exposed to air under higher pressures is decompressed too rapidly.

A

decompression

35
Q

also known as Acute mountain sickness

A

altitude sickness

36
Q

drug for prevention of altitude sickness

A

acetazolamide

37
Q

Cerebral dilatation and edema formation causing increased pressure

A

High altitude cerebral edema

38
Q

Due to vasoconstriction leading to pulmonary hypertension and pulmonary edema (dry cough, frothy pinkish secretion)

A

high altitude pulmo edema
