PCC Week 1 Questions with Verified Correct
Answers
Intracellular fluid amount
2/3 body fluid or 40%
Where is most intracellular fluid
skeletal muscle mass
Extracellular fluid amount
1/3 body fluids or 20%
Three places of extracellular fluid
intravascular, interstitial, transcellular
ECF: intravascular location
blood vessels
ECF: intravascular components
plasma, blood, WBC, platelets
ECF: intravascular plasma amount (L)
3.5L
ECF: intravascular WBC, RBC, platelet amount (L)
2.5L
ECF: interstitial location
space between cells, tissues, organs, blood vessels
, ECF: interstitial fluid amount (L)
10L
ECF: interstitial fluid and fluid balance
does not effect fluid balance, it is a reserve tank of fluids
ECF: interstitial fluid and aging
volume decreases with age which means the reserve fluid is taken from intracellular and can
shrink cells
ECF: transcelllar fluid location
fluid that sits in weird places like joints, eyes, CSF
ECF: where fluid is pulled from during dehydration/FVD
intravascular first then interstitial then intracellular
What ECF compartment will lose fluids first?
Intravascular (bleeding, vomiting, diarrhea)
Third spacing fluid shift
fluid shifts from intravascular/intracellular to interstitial, internally dehydrated but appears
swollen
Third spacing s/s
decreased UO, increased HR, decreased BP, decreased CVP, edema, increased weight,
imbalanced I/os
normal CVP
