Burns Flashcards
why does plasma seep out into the tissue?
when does most of this occur?
when does the pulse increase?
increased capillary permeability (leaky)
in the first 24 hrs
anytime you’re in a fluid volume deficit, the pulse will increase
why does the CO decrease?
why does the urine decrease?
less volume to pump out
kidneys are either trying to hold on to fluid or they arent being perfused adequately.
why is epinephrine secreted?
why are ADH and aldosterone secreted?
- makes you vasoconstrict, and shunt blood to the vital organs.
- retain sodium and water with aldosterone and retain water with ADH, therefore the blood volume goes up.
what is the most common airway injury?
why?
carbon monoxide poisoning.
-normally, oxygen binds with hemoglobin. carbon monoxide travels much faster then oxygen. therefore, it gets to hemoglobin first and binds. oxygen cant bind now because carbon monoxide is already there
when you see a client with burns to the neck/face/chest you had better think what?
what may the physician do prophylactically?
airway
Et tube
Rule of nine, what percentage is the.. head and neck arm trunk genital leg
head and neck -9 arm-9 each trunk- 18 front 18 back genital- 1 leg- 18 each
treatment for pt with burns greater than 20-25 TBSA.
- fluid replacement
- should know what time the burn occurred because fluid therapy (for the 1st 24 hrs) is based on the time is injury occurred, not when the treatment was started.
Common rule : calculate what is need for the first ______ and give ____ of the volume calculated during the first ___ hrs.
24 hours
half
8 hours
(parkland formula)
Parkland formula
(4ml of LR)x(body weight in kg)x(%of TBSA burned) = total fluid replacement for the first 24 hrs after burns.
1st 8hrs= 1/2 of total volume
2nd 8hrs= 1/4 of total volume
3rd 8hrs= 1/4 of total volume
if the client is restless, it could suggest 3 problems: inadequate fluid replacement, pain , or hypoxia
Nurse’s priority?
hypoxia
pain never killed anyone
a client was wrapped in a blanket to stop the burning process. since the flames are gone does that mean the burning has stopped?
what else could have been done to stop the burning process?
the blanket helped by … holding in the ____ and kept out ____.
NO
Cool water not ICE water because they will vasoconstrict
body heat
infection
Albumin: you know that albumin holds onto \_\_\_ in the \_\_\_ space. vascular volume? kidney perfusion? BP? CO?
fluid, vascular UP UP UP UP
- will albumin help correct a fluid volume deficit?
- why?
- when you start giving a client albumin, you know the vascular volume will ___.
- therefore, what will happen to the workload of the heart>
yes!
because we are putting more fluid in the vascular space
UP
UP
If you have stress the heart TOO much: -the client could be thrown into \_\_\_\_. -if this occurs, what will happen to CO? -lung sounds? -
fluid volume excess
DOWN
wet
in a client who is receiving fluid rapidly, what is a measurement you could take hourly to ensure you’re not overloading the client?
CVP
what immunization should be given with burn pt?
-tetanus toxoid (active immunity)
(takes 2-4 to develop their own immunity)
-immune globin (immediate protection)
(passive immunity)
if a pt has a circumferential burn on their arm, what should you be checking?
circulatory check:
- pulse
- skin color
- skin temp.
- capillary refill
