- drive equation left, H+ down
Contraction
- contracted circulating volume
Hypokalemia
- low K in blood, K shift out of cells in exchange to H in, alkalosis
- hypokalemia leads to alkalosis
- alkalosis can also cause hypokalemia
Diuretics
- high urine Cl when using diuretics
- low urine Cl when stopped
- child with symptoms similar to adults taking diuretics
- increased Na delivery to CD, increased aldosterone, increased K/H secretion = hypokalemia, alkalosis
Vomiting
- "secret"
- initial high Cl because diuretics inhibit
Hyperaldosteronism
- no fluid overload
- urinary Cl increased due to increased Na excretion
- only time low urinary Cl is vomiting
