Fluid & Electrolytes PowerPoint Flashcards
unable to produce tears until
6 weeks
3 months
infants are dependent on who for provide fluids for them
dependent
infant GI tract has what proportional surface area than adults
GI
infants have a high risk for
dehydration
kidneys cannot fully conserve fluids and electrolytes until child
2 years
newborn how much greater daily water need/kg
4-5x
increased or respiratory rate
increased
increased or decreased metabolic demands
increased
what is the largest part of body
largest
high metabolic rate + decreased fluid reserve =
increased risk for imbalance
throw up goes to what acid base imbalance
alkaloid
- diarrhea acid
intracellular accounts for how much
2/3
extracellular accounts for how much
1/3
difussion
movement from greater to lesser concentration
microtubules
immature so they have difficulty in maintaining the sodium & calcium, increase risk for acidosis
children have higher or lower metabolic rate
higher
vascular volume
cap refil
character of pulse
BP *late sign
central venous pressure
tenseness of fontanelle
I & O
tears
urine specific gravity
mucous membrane
skin turgor
presence of absence of edema
LOC
1kg =
1L
normal U/O children
0.5 to 1mL/kg/hr
normal U/O infant
2mL/kg/hr
3 main ways to become dehydration
decreased intake
decreased output
translocation
common cause of dehydration
diarrhea
vomiting
gastroenteritis
pharyngitis
febrile illness
DKA
DI
burns
isotonic dehydration
sodium and water are lost in proportion to each other and therefore serum sodium is normal
hypotonic dehydration
sodium loss is greater than water loss so serum sodium levels are low
fluid shifts from the ECF to ICF to attempt to correct the loss causing worsening ECF dehydration
