Answers ✅-thermal: most common, hot surfaces
-chemical: direct contact w/ acids, alkalis (can liquify tissue)
or organic compounds (acids: rust removers, BR cleaners;
alkalis: oven cleaner, fertilizer; organic: gas, disinfectants); remove clothing w/ contact and irrigate w/ water
-electrical: voltage or lightening, can also cause thermal burn
-smoke/inhalation: higher mortality rate, rapidly assess, can
cause metabolic asphyxiation (cardiac monoxide poisoning), results in hypoxia, tx w/ 100% humidified O2 what are the effects of electrical burns? - Correct Answers
✅-neuro: loss of memory, coma, assume cervical injury &
immobilize 1 / 3

-MSK: muscular breakdown w/ deep necrosis, rhabdo, tetany
including diaphragm, heart & other muscles, limb tetany can lead to bone fractures
-CV: lesions, circulatory arrest, place on ECG & tx
dysrhythmias
-Renal: renal injury, ATN, necrosis from rhabdo, AKI; monitor
urine output, insert foley, I&O, creatinine
-Respiratory: lesions, tetany, resp. arrest from alveolar
damage; monitor RR & effort, monitor O2 sat, administer O2 via NRB or bag mask what are the clinical manifestations & treatment of smoke/inhalation burns? - Correct Answers ✅-upper
airway: hoarseness from progressive laryngeal edema w/ in
18-24 hrs, swallowing difficulty, copious secretions, use of access. muscles, airway swelling/obstruction can be rapid & massive
-lower airway: facial burns, singed nasal or facial hair,
dyspnea, carbonaceous sputum, wheezing, altered mental
-tx: airway!, tx edema from injury, humidified O2!, intubate to
protect airway from edema what are the differences between partial thickness & full
thickness burns? - Correct Answers ✅-partial: bright red to

-perineal area: 1%
what should be done in the care of burns in the prehospital
phase? - Correct Answers ✅-stop the burn: remove pt from
source -if TBSA> 10%, assess ABCs if responsive, if unresponsive CPR
-cervial-spine stabilization: assume fall, protect airway
-oxygen: 100% humidified w/ NRB, if inadeq or
hypoventilation- bag w/ 15L O2
-IV access: emergency management, hypovolemic shock
-wound care: chemical (remove particles), thermal (cover w/
clean, cool towel)
-avoid heat loss: wrap in dry blanket
-elevate burned area above heart to reduce edema
