hypokalemia Flashcards
hypokalemia
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
hypokalemia causes
inadequate intake (rare)
cellular shift
- bronchodilators
- insulin
- alkalosis
excessive loss potassium loss:
-gastrointestinal vs renal
hypokaelmia renal losses - normal BP
normal BP
Alkalosis:
low urine cl = vomiting
high urine cl:
diuretics
bartter syndrome
gitelmans syndrome
Acidosis:
renal tubular acidosis
diabetic ketoacidosis
hypokaelmia renal losses - normal BP
low aldosterone:
liddle syndrome
cushing syndrome
licorice
high aldosterone
primary hyperaldosteronism
high renin:
renal artery stenosis
renin secreting tumor
