treatment for hypokalemia - ANSWER 1. administer potassium orally or IV
(drip only)
-Lidocaine for pain
-Liquid potassium by mouth can cause GI lesions
treatment for hyperkalemia - ANSWER 1. stop/limit potassium intake
2. dialysis
3. Kayexalate - a cation exchange resin given orally or rectally to bind with
potassium
4. force potassium from ECF to ICF with IV insulin with dextrose- causes
increase potassium intake at cellular level, beta adrenergic agonists, NaHCO3-
moves Na into cells
5. stabilize cardiac membranes with IV calcium chloride or gluconate - types of
calcium

sign to test for hypocalcemia in which you tap on facial nerve leading to facial
contractions - ANSWER Chvostek's sign
, sign to test for hypocalcemia in which you inflate BP cuff above systolic bp
leading to carpal spasms - ANSWER Trousseau's sign
treatment for hypocalcemia - ANSWER 1. oral or IV calcium
2. promote CO2 retention- to control muscle spasms
treatment for hypercalcemia - ANSWER 1. IV or oral fluids with normal
saline - flushes out excess calcium
2. IV phosphorus- opposes calcium
3. Calcitonin- decreases calcium
4. Biphosphonates- impede bone resorption
5. low calcium diet
