Hyperkalemia Flashcards
Most of the body’s potassium is found in the _______________ part of the cell compared to the extracellular which is where sodium is mainly found
intracellular
potassium is responsible for _________ impulse conduction and _________ contraction.
nerve; muscle
The Body CARED too much about Potassium”
causes of hyperkalemia
Cellular Movement of Potassium from Intracellular to extracellular (burns, tissue damages, acidosis)
Adrenal Insufficiency with Addison’s Disease
Renal Failure
Excessive Potassium intake
Drugs (potassium-sparing drugs like aldactone (spiroaldactone), Triamterene, ACE inhibitors, NSAIDS
signs & symptoms of hyperkalemia
MURDER
Muscle weakness
Urine production little or none (renal failure)
Respiratory failure (due to the decreased ability to use breathing muscles or seizures develop)
Decreased cardiac contractility (weak pulse, low blood pressure)
Early signs of muscle twitches/cramps…late profound weakness, flaccid
Rhythm changes: Tall peaked T waves, flat p waves, Widened QRS and prolonged PR interval
Remember the word POTASSIUM for food rich in potassium
Potatoes, pork
Oranges
Tomatoes
Avocados
Strawberries,
Spinach
fIsh
mUshrooms
Musk Melons: cantaloupe
Also included are carrots, cantaloupe, raisins, bananas.
______________ is sometimes ordered and given PO or via enema. This drug promotes GI sodium absorption which causes potassium excretion.
Doctor may order potassium _________ drugs like Lasix or Hydrochlorothiazide
Administer a _____________ solution of glucose and regular insulin to pull the potassium into the cell
Kayexalate; wasting; hypertonic
any potassium level higher than _____________ is especially dangerous
7.0
how does hyperkalemia affect the ECG ?
Prolonged PR interval
wide QRS
tall, peaked T waves
flat or absent P waves
interventions for the patient with hyperkalemia
monitor the patients cardiac, respiratory, neuromuscular, GI status
_____________IV potassium infusion or hold supplements
initiate K+ restrictive diet
prepare patient for ________________-
stop; dialysis
Lasix is a potassium _____________ drug
wasting
