Rationales Included
, Loss of electrolytes along with fluid is termed ___ Isotonic fluid volume deficit
___ - loss of sodium and water at the same time Isotonic dehydration
Hypotonic dehydration - ___ > loss of sodium than water
Hypertonic dehydration - ___ < loss of sodium than water
fluid is not where its supposed to be is called ___ (Fluid third spacing
shifts from vascular space to other area)
third spacing often occurs where? in interstitial tissues
Trapped fluid in abdomen is called ___ (trapped fluid = ascites
volume loss)
Assessing extent of FVD difficult because ___ it may not be reflected in measurable data (no change in body weight)
FVD may be a result of excessive fluid loss like these for excessive loss of GI fluids (most common)
example: Vomiting
Diarrhea
GI suctioning
Intestinal fistulas
other causes of fluid loss: Excessive renal loss
Heavy sweating
Hemorrhage
Chronic abuse of laxatives, enemas
Insufficient intake of fluid may result from: Lack of access to fluids
Inability to request or swallow fluids
and ultimately lead to FVD Oral trauma
Altered thirst mechanisms
Excessive exercise during very hot weather
Burns of the skin may result in FVD because ___ can lead Loss of fluids and serum proteins
to hyponatermia (an electrolyte imbalance)
with burns, Fluids leak into ___ spaces interstitial
___ is most commonly seen after initial period after burn Hypotonic dehydration
___ and ___ dehydration is first imbalance occurred after Hyponatremia, dehydration
burn
