Fluid Electrolyte 2 Flashcards
ECF=
And how much body fluids
Extracellular fluid
1/4-1/3
ICF =
And how much body fluid
Intracellular fluid
2/3-3/4 of the body fluids
There are two types of ECF (Extracellular fluid) what do they do
Intravacular fluids pick up o2 in lungs and nutrients in the gastrointestinal system to the interstitial fluid to cell where o2 and nutrients are used for by the cell
ICF deficit- hypovolemia
Dehydration
Decrease in fluid intake or marked increase in fluid output
What are the Causes and s/s of hypovolemia
Causes-Hyperventilation, diarrhea, vomiting,
S/S postural hypertension, weight loss, elevated temp, oliguria (report)
Weak rapid pulse
ECF excess- hypervolemia
Increase blood volume
Edema increase fluid interstitial compartments
Increase Extracellular osmolarity
What are the cause and s/s of hypervolemia
Cardiac insufficiency- decrease renal perfusion
Protein depletion- decrease plasma protein
Rapid administration of Iv saline
cirrhosis
Excessive water intake
S/S - peripheral edema, moist coracle lungs, wt gain, distend veins,
What is third spacing
Fluid where is shift to a cavity where it shouldn’t be
What is ascites
Fluid shifted into the abdomen
Hypokalemia occurs (causes) when
Lab value
Abbr
<3.5, k+ Poor intake of k+ Iv fluids for several days without dietary supplements of k+ Excessive use of diuretic Increase aldosterone secretion
s/s of Hypokalemia
Myocardial irritability ( arrhythmias, weak and irregular pulse)
Anorexia, vomiting, abdominal distinction, paralytic ileus
Profound muscle weakness
Postural hypotension
Hyperkalemia occurs when
Lab value
> 5.3
Supplements no longer needed
Renal failure , insulin insuffinencicy
Acidosis- k+ shift out of cells in exchange for h+
S/s of Hyperkalemia
> 8
GI hyperactivity
Confusion and irritability
Hypocalcemia occurs when lab value
< 4.3 Poor dietary intake of calcium and vitamin d defiency Loss via kidney Metabolic alkalosis Decrease in parathyroid hormone
S/s of hypocalcemia
Increase excitability Tetany - muscle spasm, sharp flexion of wrist and ankles Parathesias-numbness Anxiety, irritability Altered bleeding and clotting time
