ELECTROLYTES Flashcards
FROM MOTHER NOTES, FINAL COACHING, GFC
major EXTRACELLULAR CATION
SODIUM
major contributor to PLASMA OSMOLALITY
SODIUM
essential for normal neuromuscular function and cardiac impulse conduction
POTASSIUM
serum level maintained by GI absorption and excretion and renal absorption and excretion
SODIUM
abnormal levels are associated with acid-base disorders
BICARBONATE
used to monitor px with acid-base imbalance, coagulation disorders, pathologic bone disorders, endocrine disorders, cardiac arrhythmias, muscle disorders
CALCIUM
maintains electroneutrality and fluid balance
CHLORIDE
almost found in all bone; in serum, may be bound to albumin or other plasma proteins
MAGNESIUM
as sodium is reabsorbed, it is lost
HYDROGEN
regulated by ALDOSTERONE and ADH
SODIUM
levels often change proportionally to sodium levels
CHLORIDE
helps evaluate electrolyte disorders such as hypocalcemia, hypokalemia, acid-base balance
CHLORIDE
monitor pregnant px with severe toxemia in PRE-ECLAMPSIA
MAGNESIUM
MAJOR ELECTROLYTE PRESENT IN ALL BOSY FLUIDS; freely excreted by the kidneys and not stored by the body
POTASSIUM
accounts for more than 90% OF TOTAL CO2
BICARBONATE
PARALLEL LOSS of WATER & ELECTROLYTES
ISOTONIC DEHYDRATION
INFUSION OF NORMAL SALINE to px with disturbed renal function leads to ___________
ISOTONIC HYPERHYDRATION
CHOLRIDE REABSORPTION IN THE PCT
PASSIVE
CHLORIDE REABSORPTION IN THE ALOH
ACTIVE
this results from renal insufficiency or drinking extraordinary amounts of water
HYPOTONIC HYDRATION
drug that stimulates SWEAT PRODUCTION
PILOCARPINE
MOST IMPORTANT CONTROL OF CALCIUM HOMEOSTASIS
PTH
the MOST IMPORTANT in STIMULATING WATER CONSERVATION in the kidneys
ADH
ISE membrane in SODIUM
GLASS (GLASS ELECTRODE)
colorimetric method used in SODIUM
ALBANESE-LEIN
ISE membrane in POTASSIUM
VALINOMYCIN
