16
Q

Gray

A

A unit of absorbed radiation dose equal to 100rads.

17
Q

Hyper-metabolic Phase

A

Stage of the burn process in which there is increased body metabolism in an attempt by the body to heal the burn.

18
Q

Intravascular Space

A

The volume contained by all the arteries, veins, capillaries, and other components of the circulatory system.

19
Q

Ionization

A

the process of changing a substance into separate charged particle ions

20
Q

Jackson’s Theory of Thermal Wounds

A

explanation of the physical effects of thermal burns

21
Q

Joule’s Law

A

The physical law stating that the rate of heat production is directly proportional to the resistance of the circuit and to the square of the current

22
Q

Liquefaction Necrosis

A

The process in which an alkali dissolves and liquefies tissue

23
Q

Neutron Radiation

A

Powerful radiation with penetrating properties between that of beta and gamma radiation

24
Q

Ohm

A

Basic unit for measuring the strength of electrical resistance

25
Q

Ohm’s Law

A

The physical law identifying that the current in an electrical circuit is directly proportional to the voltage and inversely proportional ot the resistance

26
Q

Partial Thickness Burn

A

burn in which the epidermis is burned through and the dermis is damaged; characterized by redness and blistering; also called a second degree burn

27
Q

Rad

A

basic unit of absorbed radiation dose

28
Q

Resistance

A

property of a conductor that opposes the passage of an electric current

29
Q

Resolution Phase

A

Final stage of the burn process in which scar tissue is laid down and the healing process is completed

30
Q

Rule of Nines

A

method of estimating amour of BSA burned by division of the body into regions, each of which represents approximately 9 percent of total BSA (Plus 1% for Genital Region)

31
Q

Rule of Palms

A

Method of Estimating amount of BSA burned that sizes the area burned in comparison to the patient’s palmar surface

32
Q

Subglottic

A

Reffering to the lower airway

33
Q

Supraglottic

A

Referring to the upper airway

34
Q

Superficial Burn

A

a burn that involves only the epidermis; characterized by reddening of the skin; also called a first degree burn

35
Q

Voltage

A

the difference of electric potential between two points with different concentrations of electrons

36
Q

Zone of Coagulation

A

Area in a burn nearest the heat source that suffers the most damage and is characterized by clotted blood and thromboses blood vessels

37
Q

Zone of Hyperemia

A

area peripheral to a burn that is characterized by increased blood flow

38
Q

Zone of Stasis

A

Area in a burn surrounding the zone of coagulation that is characterized by decreased blood flow.
