What is the tx for isotonic dehydration?
|
tx underlying cause, replace fluids with iso or match type of loss, monitor daily I/O, skin turgor, LOC, VS, BUN, hematocrit, Lytes
|
|
What are the hypokalemia serum levels?
|
Mild: 3-3.5 meq/L
Modd: 2.5-3.0 meq/L Sev: <2.5 meq/L |
|
causes & process of hypokalemia
|
excessive excretion or inadequate intake of K, transcellular shift ECF to ICF
|
|
tx for isotonic overhydration
and goal |
underlying cause, restrict fluids, diuretics, monitor daily: I/O, VS, CXR, BUN, hematocrit
Goal: urine excretion= 1ml/kg/hr |
|
tx for hypokalemia
|
correct underlying cause: hypomagnesemia, K supplements, K-sparing diuretic
