AE3 Exam 2 Questions with Complete Solutions (Latest 2025) What other organ system concern is there for electrical burns? - Correct Answers ✅Cardiovascular -- damage up to 48 hours after, needs monitoring GI -- changes mucosa, changes to flora, hypovolemia can lead to ileus What is the pathological cascade that starts with a burn and leads to shock? - Correct Answers ✅Burn = massive inflammatory shock --> leads to increased vascular permeability and vasodilation --> causes edema and decreases intravascular blood volume (goes into interstitial space )3rd spacing)) --> overall decreased blood volume r/t fluid loss but increased hemoconcentration --> increased Hct, Hbg --> increased blood viscocity --> increased peripheral resistance, coagulation low fluid and low circulation --> burn shock What is the difference between superficial, superficial partial- thickness, deep partial-thickness and full-thickness burns? - Correct Answers ✅SUPERFICIAL
- only top layer (epidermis) of skin 1 / 4
AE3 Exam 2 Questions with Complete Solutions (Latest 2025)

SUPERFICIAL PARTIAL THICKNESS
- entire epidermis and maybe top parts of dermis destroyed
- heals in 10-21 days (uncomplicated)
- blistered, moist, painful
DEEP PARTIAL THICKNESS
- extends into deeper layers of dermis
- heals in 2-6 weeks
- blistered, moist, painful
FULL THICKNESS
- burns through entire dermis and may extend into SQ tissue,
- dry, discolored (black), no pain
