Fluid and Electrolyte Imbalances Flashcards
dehydration
fluid intake less than needed causing fluid volume deficit
signs of dehydration
low UO, altered mental status, poor turgor, weak HR, sunken eyes, dry mucus membranes
things to monitor for dehydration
measure I/O, bowel movements, BUN, creatinine
causes of dehydration
inadequate fluid intake, burns, wound drainage, low sodium diet, diuretics, vomit/diarrhea, AVP-D
dehydration lab assessment
elevated hemoglobin/hematocrit/serum osmolarity/glucose/albumin/BUN/electrolytes/creatinine, hemoconcentration
fluid overload
fluid intake or retention leading to fluid volume excess
primary problems for dehydration
poor perfusion from excess fluid loss/poor intake and injury from weakness
medication treatment for dehydration
antidiarrheals, antimicrobial, antiemetic, antipyretics, desmopressin
signs of fluid overload
edema, high BP, increased wt, SOB, crackles, jug vein distention, headache, high UO, bounding pulse
cause of fluid overload
severe overload, hypervolemia, excess body fluid
hyponatremia values
sodium under 136 mEq/L
causes of hyponatremia
increase sodium loss OR excess water
signs of hyponatremia
seizures, confusion, coma, increased intracranial pressure, tachycardia, hypotension, poor turgor, diarrhea
treatment for hyponatremia
sodium replacement, increase salt intake, manitol
hyponatremia monitoring
I/O, urine specific gravity, heart and resp, wt, neuro status
hypernatremia value
sodium above 145 mEq/L
causes of hypernatremia
dehydration, excess sodium intake, regulatory abnls
signs of hypernatremia
short attention span, agitated, confusion, coma, seizures, hypovolemia, PE, low O2 sat
treatment for hypernatremia
lasix, sodium free IV, low sodium diet, fluids
hypokalemia value
potassium below 3.5 mEq/L
hypernatremia monitor
VS, I/O, wts, edema
causes of hypokalemia
diuretics, diarrhea, metabolic/resp alkalosis
signs of hypokalemia
dysrhythmias, rapid thready pulse, weakness
treatment for hypokalemia
fruits and veggies, IV no faster than 10 mEq/hr
monitor for hypokalemia
safety, diet, diuretic potassium sparing
hyperkalemia values
potassium higher than 5.0 mEq/L
hyperkalemia cause
potassium sparing diuretics, salt substitutes, infusing potassium, kidney failure
signs of hyperkalemia
bradycardia leading to VFIB, hypotension, muscle twitching, weakness, diarrhea
hyperkalemia treatment
sodium polystyrene, D50 w 10 units reg insulin
hyperkalemia monitoring
diet, avoid salt substitutes, increased fluid intake
