hypokalemia Flashcards

1
Q

hypokalemia

A

low serum potassium

potassium enters the body via oral intake or intravenous infusion, is largely stored in the cells, and then excreted in the urine. Thus, decreased intake, increased translocation into the cells, or, most often, increased losses in the urine, gastrointestinal tract, or sweat can lead to a reduction in the serum potassium concentration
