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
