Meadows2 Flashcards
Treated with fluid restriction
SIADH
Symptoms attributable to hyponatremia itself should be given
Hypertonic saline
To treat small cell lung cancer with SIADH
Limit amount of fluid intake
Major intracellular cation
Potassium
Very little in circulation. Shifts across cell membranes with pH changes
Potassium
During academia
Hyperkalemia
During alkalemia
Have hypokalemia
Hyperkalemia is greater than
5
Excessive intake, acidosis, lack of aldosterone, severe volume depletion, drugs
Hyperkalemia
Common in acute and chronic renal failure
Hyperkalemia
Treated with IV fluids to restore volume
Hypovolemic
Usually no PE findings
Hyperkalemia
Check EKG for conduction abnormalities.
Hyperkalemia
Repeat blood test to rule out hemolysis of lysed RBCs in the tube
Hyperkalemia
If person has muscle weakness, be suspicious of
Cardiac effects
Given if EKG changes are present in Hyperkalemia
Calcium gluconate
Shifts K into cells
Insulin and albuterol
Given to increase K excretion
K binding resin
Necessary in acute renal failure with Hyperkalemia
Hemodialysis
Hypokalemia is less than
3.5
Potassium loss from diarrhea, diuretics, magnesium deficiency, alkalemia-mediated shift. Common in diuretics.
Hypokalemia
Arrhythmia risk
Hypokalemia
Muscle twitching or weakness in severe cases
Hypokalemia
Alkalosis from vomiting can secondarily cause
Hypokalemia
