Hyperkalemia Flashcards
Hyperkalemia
Means: high potassium in blood
Normal potassium level: 3.5-5.1 and 7.0 and up is dangerous
Extracellular fluid: fluid outside of cell
Intracellular fluid: fluid inside the cell
Blood test: if a doctor orders a blood test to test for potassium, they are looking for the levels outside the cell in the extracellular fluid.
Hyperkalemia potassium
Potassium is responsible for cardiac/heart
- if kidneys don’t work then potassium increases
Causes for high potassium- hyperkalemia
Remember “body CARED too much for potassium”
C- cellular movement of k+ from intracell to extracellular (burns, tissue damage)-Acidosis
A- adrenal insufficiency (Addison disease)-hypoaldosteronism
R- renal failure
E- excessive potassium intake
D- drugs- potassium-sparing diuretics: aldacton, trianterne, ACE inhibitors)
Signs and symptoms for hyperkalemia
Remember “murder”
M- muscle weakness
U- urine production low/absent
R- respiratory failure (muscle weakness/seizures)
D- dysrhythmias ( decrease cardiac contractility, decrease pulse, low blood pressure)
E- early signs of muscle twitching- flaccid paralysis(loose limbs)
R- rhythm changes- tall T waves, flat P waves, wide QRS complex
Nursing interventions for hyperkalemia
Monitor input and outtake
Monitor potassium level
Doctors may order hypertonic solution, cause potassium to go back into cell
Prepare for dialysis- keeps body in balance
Initiate potassium strict diet
Potatoes,oranges,tomatoes,strawberries,spinach,fish,mushroom, cantaloupe
Kayexalate- sodium absorption which promotes potassium secretion, enema or po
