Flashcards in Ch. 23 Disorders of Daily Life Deck (87):
1

seriousness of thermal burns determined by

depth, % body surface area, baux score, lung injury, rapid Rx

2

depth of thermal burns: confined to epidermis

superficial

3

depth of thermal burns: dermis involved

partial thickness

4

depth of thermal burns: through dermis to fat, muscle, bone

full thickness

5

depth of thermal burns: red, blanche to pressure, no vesicles (blisters), no edema, painful, dry, no scar

superficial

6

depth of thermal burns: vesicles (blisters), red, do not blanche to pressure, always edematous, painful, wet, heal with scar

partial thickness

7

depth of thermal burns: charred or translucent, vesselsvisible, often painless (nerve destruction), pain from partial thickness burns at edges, heal with scar

full thickness

8

Baux score

age + percent BSA= estimated mortality

9

LD50=
(baux score of 50% people die)

BS 109

10

lung injury adds ( ) to age plus BSA

17

11

2 biggest complaints of burn victims

thirsty and cold

12

freezing of superficial skin

frostnip

13

cold injury: firm white patches, peel or blister with rewarming

14

cold injury: dermis and deeper

frostbite

15

cold injury: hard, white, lacks feeling. may blister with rewarming. may cause gangrene

frostbite

16

cold injury: cole temp, wet clothes, alcohol (peripheral vasodilation). Lethargy, cluminess, confusion, low respiratory and heart rates

hypothermia

17

key of heat stroke

high body temp but no sweating

18

molecular damage

22

ionizing radiation: ( ) cause molecular damage that cannot be reversed

high energy

23

most common high energy ionizing radiation

skin cancers from UV damage

24

ionizing radiation: ( ) is cumulative for life

effect

25

effect of ionizing radiation depends on...

field size, rate of cell proliferation, tissue oxygenation

26

effect of ionizing radiation: radiation Rx= intense to small field; whole body= lower level can be fatal

field size

27

effect of ionizing radiation: high: bone marrow, lymphoid, GI and respiratory epithelius, gonads, epidermis;
low: muscle/bone

rate of cell prolferation

28

effect of ionizing radiation: high O2 more vulnerable; ractive oxygen species enhance damage

tissue oxygenation

29

ionizing radiation: ifections (lymphoid, BM), diarrhea (GI mucosa)

acute radiation sickess

30

heat illness: profuse sweating, sudden weakness, disorientation, fainting

heat exhaustion

31

heat illness: body temp 102

heat exhaustion

32

heat illness: body temp 104

heat stroke

33

heat illness: headache, nausea, vomiting, very rapid HR and respiratory rate, weakness or rigity, disorientation, coma

het stroke

34

heat illness: heat cram Rx

rehydration, electrolyte

35

heat illness: heat exhaustion Rx

relief from heat, fluid, electrolytes

36

heat illness: heat stroke Rx

rapid cooling, cold IV fluids, half dies is body temp rises to 106

37
