potassium-depleting diuretic warnings
- prescribe cautiously in pts. allergic to sulfonamides
- may cause hypokalemia
- may cause muscle cramps and weakness
- may cause phototoxic reactions
- take early in the morning to avoid nocturia
hypokalemia symptoms
leg cramps and fatigue
normal serum potassium level
3.5-5mEq/L
Micro K, K-Dur, Klor-Con
potassium chloride 8mEq=600mg KCl 10mEq=750mg KCl 15mEq=1,125mg KCl 20mEq=1,500mg KCl
potassium-sparing diuretics (3)
-spare potassium from leaving in urine

pt. counseling for potassium-sparing diuretics
- avoid salt substitutes because they are potassium based
- take early in the morning
- BBW: hyperkalemia may occur
nocturia
excessive urination at night
Kayexalate
sodium polystyrene sulfonate
- used in Tx of hyperkalemia
- it is a cation exchange resin: sodium ions are exchanged with potassium ions and resin is excreted
