how do we lose electrolytes? sweating, vomiting/diarrhea, urine, lung expansion
what is the normal range for sodium? 135-145
how do sodium imbalances occur? due to cellular fluid shifts
what is hyponatremia? low sodium in the blood
what are the causes of hyponatremia? - excessive sweating
- loop/thiazide diuretics
- ng tube continuous suction
what are the s/s of hyponatremia? - headache
- lethargy
- papilledema
- weight gain and edema
- n/v
what is a nursing intervention for monitor for cns (neuro) changes
hyponatremia?
what is the cause of hypernatremia? hypertonic enteral feeding/receiving GT tube without
any water flushes
what are the s/s of hypernatremia? - neuro deficits (confusion)
- seziures
, what is a nursing intervention for assess deep tendon reflexes
hypernatremia?
what is the treatment for diuretics and hypotonic IVF (5% d5w)
hypernatremia?
what is the normal range for 3.5-5
potassium?
what does hypokalemia affect? resting membrane potential of the cell that will result
in skeletal muscle weakness
what is the cause of hypokalemia? loop/thiazide diuretics (you are urinating K+ out)
what are the s/s of hypokalemia? - weakness/fatigue
- arrhythmias
- weak/irregular pulse
what are nursing interventions for - diet high in K+
hypokalemia? - never IV push
- a critically low K+ will require IV pump and
potassium replacement therapy
- monitor K+ level if on diuretics --> may need a med
change or added K+ supplementation
what do we always want to be cardiac dysrhythmias
concerned about with hyperkalemia?
what would an EKG show for tall, peaked T waves
hyperkalemia?
what are foods high in potassium? spinach, watermelon, sweet potatoes
what hormone is associated with parathyroid hormone
calcium imbalances?
what is the cause of hypocalcemia? - low parathyroid hormone
- chronic kidney disease
