Description:

Author: Dylan Luyten, MD

Educational Pearls:

 

  • Most important questions to answer with low potassium are 1. What are their symptoms? 2. Can they take potassium by mouth?
  • Oral repletion is faster, cheaper, and more effective than IV repletion.
  • Give IV potassium when patients have K
  • Most patients who are hypokalemic are hypomagnesemic and require magnesium supplementation.  Checking a level is unnecessary.
