Ch. 23 Disorders of Daily Life Flashcards
seriousness of thermal burns determined by
depth, % body surface area, baux score, lung injury, rapid Rx
depth of thermal burns: confined to epidermis
superficial
depth of thermal burns: dermis involved
partial thickness
depth of thermal burns: through dermis to fat, muscle, bone
full thickness
depth of thermal burns: red, blanche to pressure, no vesicles (blisters), no edema, painful, dry, no scar
superficial
depth of thermal burns: vesicles (blisters), red, do not blanche to pressure, always edematous, painful, wet, heal with scar
partial thickness
depth of thermal burns: charred or translucent, vesselsvisible, often painless (nerve destruction), pain from partial thickness burns at edges, heal with scar
full thickness
Baux score
age + percent BSA= estimated mortality
LD50=
baux score of 50% people die
BS 109
lung injury adds ( ) to age plus BSA

2 biggest complaints of burn victims
thirsty and cold
freezing of superficial skin
frostnip
cold injury: firm white patches, peel or blister with rewarming
frostnip
cold injury: dermis and deeper
frostbite
cold injury: hard, white, lacks feeling. may blister with rewarming. may cause gangrene
frostbite
cold injury: cole temp, wet clothes, alcohol (peripheral vasodilation). Lethargy, cluminess, confusion, low respiratory and heart rates
hypothermia
key of heat stroke
high body temp but no sweating
heat illness: dehydration and electrolyte loss
muscle spasms
elecritcal injury: burns, intravascular coagulation
heat injury
elecritcal injury: cardiac arrhythmia, muscle spasms, seizure, respiratory arrest
electrical dysfunction
ionizing radiation: low energy radiation (visible light, radio, radar) does no ( )
molecular damage
ionizing radiation: ( ) cause molecular damage that cannot be reversed
high energy
most common high energy ionizing radiation
skin cancers from UV damage
ionizing radiation: ( ) is cumulative for life
effect
effect of ionizing radiation depends on…
field size, rate of cell proliferation, tissue oxygenation
effect of ionizing radiation: radiation Rx= intense to small field; whole body= lower level can be fatal
field size
effect of ionizing radiation: high: bone marrow, lymphoid, GI and respiratory epithelius, gonads, epidermis;
low: muscle/bone
rate of cell prolferation
effect of ionizing radiation: high O2 more vulnerable; ractive oxygen species enhance damage
tissue oxygenation
ionizing radiation: ifections (lymphoid, BM), diarrhea (GI mucosa)
acute radiation sickess
heat illness: profuse sweating, sudden weakness, disorientation, fainting
heat exhaustion
heat illness: body temp 102
heat exhaustion
heat illness: body temp 104
heat stroke
heat illness: headache, nausea, vomiting, very rapid HR and respiratory rate, weakness or rigity, disorientation, coma
het stroke
heat illness: heat cram Rx
rehydration, electrolyte
