Module 5 Flashcards
Sodium Bicarbonate
MOA
Dissociates to provide ion to neutralize ion concentration which raised blood and urinary pH.
Also increases concentration of Na in plasma
Sodium bicarbonate
Indications
Metabolic acidosis
Hyponatremia
Sodium bicarbonate
Side effects
Edema, cerebral hemorrhage, electrolyte abnormalities, metabolic alkalosis, flatulence, tetany, pulmonary edema, heart failure exacerbation
Sodium bicarbonate
Nursing considerations
PO ONLY!
Monitor cardiac ABGs and electrolytes
Give 1-3 hours before or after meals
Lots of drug interactions if given with anything that includes Na
Potassium chloride (KCl)
MOA
Adds K and Cl
Potassium chloride (KCl)
Indications
Treat/prevent K depletions when dietary measures fail
Hypokalemia
Potassium chloride (KCl)
Side effects
Renal failure
May cause phlebitis, N/V, GI ulcers, bleeding
Potassium chloride (KCl)
Nursing Considerations
Pt must have urine output!!!Never give IV Push!!!!!!
IV must be given slowly!!! 10-20 mEq/hr
PO must be diluted to lower GI distress, tastes awful, very large pills
Think Potassium (K) think
Heart
Sodium polystyrene sulfonate (Kayexalate)
MOA
Binds to K in digestive tract replacing K ions for Na ions. Potential to drop K by 0.5-1.0 mEq/L in 4-6 hrs
Sodium polystyrene sulfonate (Kayexalate)
Indications
Hyperkalemia
Sodium polystyrene sulfonate (Kayexalate)
Side effects
Constipation, N/V/D, hypokalemia
Serious- intestinal obstruction or necrosis
Sodium polystyrene sulfonate (Kayexalate)
Nursing Considerations
Pt must have normal bowel functions
Pt will poop a lot!!!
D50/insulin
MOA
Shifts K into the cells temporarily
D50/insulin
Indications
Hyperkalemia
D50/insulin
Side effects
Hypokalemia
D50/insulin
Nursing considerations
For emergencies!!!!!
Check glucose levels before and after administering
Called a Lytic cocktail
Magnesium sulfate & magnesium oxide
MOA
Replaces magnesium
Magnesium sulfate & magnesium oxide
Indications
Hypomagnesemia
Prevent/treat seizures I. Pre-eclampsia, treat cardiac rhythm disturbances
Constipation
Magnesium sulfate & magnesium oxide
Side effects
Hypermagnesemia
Presents as confusion, sluggish, slow movements, SOA, nausea, dizzy (from low calcium) and abnormal heart rhythm
Magnesium sulfate & magnesium oxide
Nursing considerations
Can burn when given by IV
Mag Oxide (antacid) can be give for long term low mag
Think Magnesium think
Muscle and movement
Think sodium (Na) think
Brain
Calcium (Ca)
MOA
Replaces calcium
Calcium (Ca)
Indications
Hypocalcemia
