NUR 430 FINAL EXAM QUESTIONS AND ANSWERS 100%
CORRECT!!
zone of coagulation
Answers "central zone"
site of most severe damage
site of greatest heat transfer, leading to irreversible skin death
ne of stasiszo
Answers characterized by impaired circulation that can lead to cessation of blood
flow caused by a pronounced inflammatory reaction
Site is potentially salvageable; however, local or systemic factors can convert it
into a full-thickness injury
how long does it take to determine the full extent of injury in the zone of stasis?
Answers 48 - 72 hrs
it can evolve so needs to be watched carefully
rule of 9s
Answers used to determine size of injury
