Question 1 of 5
The healthcare provider prescribes magnesium sulfate 4 grams intravenously (IV) to be infused over 20 minutes for a client with preeclampsia. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse program the infusion pump?
Correct Answer: 300 mL/hour
Rationale: Calculate the volume for 4 grams: 4 grams ÷ 20 grams × 500 mL = 100 mL. Infuse over 20 minutes: 100 mL ÷ 20 minutes × 60 minutes/hour = 300 mL/hour.
