ACTIVE LEARNING TEMPLATE: Medication Anticonvulsant: Magnesium Sulfate 9 ___________ MEDICATION __________________________________________________________________________ REVIEW MODULE CHAPTER Minerals electrolytes CATEGORY CLASS ______________________________________________________________________ PURPOSE OF MEDICATION Expected Pharmacological Action -essential for the activity of many enzymes -plays an important role in neurotransmission and muscular excitability Complications -flushing, diaphoresis -drowsiness, muscle weakness, maternal hypotension, bradycardia, bradypnea depressed/absent deep tendon reflexes(DTRs) -altered LOC -decreased urine output -magnesium toxicity -reduced variability of fetal heart rate Therapeutic Use -prevent and treat seizure activity in client with sever preeclampsia or eclampsia Medication Administration -loading dose of 4-6g magnesium sulfate intermittent IV bolus as a secondary infusion over 15-30min. use a volumetric pump to ensure accuracy of dose -administer maintenace dose by contonuos infusion at 2g/hr -monitor BP levels to maintain therapeutic level at 4-7 mEq/L Contraindications/Precautions -anuria -hypermagnesemia -heart block -hypocalcemia -kidney disease -cardiac disease Interactions -decreased absorption of tetracyclines -Ca channel blockers-increases antihypertensive effects Nursing Interventions -monitor infusion site -check client for adverse effects -check client before and throughout therapy for headache, dizziness, blurred vision, and muscle weakness -monitor BP, pulse, and RR every 15-30min -report RR of 12/min or less monitor DTRs every 1-4 hr -d/c infusion and notify provider of diminished/ absent reflex -monitor LOC before initiation of medication and through therapy -monitor strict input and output, w/ urinary output hourly -monitor serum magnesium levels -ensure antidote for toxicity, calcium gluconate or calcium chloride is readily available -monitor breath sounds, report sounds of crackles monitor fetal HR for decreased variability Client Education Evaluation of Medication Effectiveness -normal serum magnesium concentrations -control of seizures associated with toxemias of pregnancy -change postions slowly from supine to upright and to sit until dizziness resolves -explain purpose of strict measurement of ral intake and urinary output -explain this medication is used to prevent seizures -explain importance of frequent monitoring of respiratory status -explain importance of frequent monitoring of fetal HR
