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? (Enter numerical value only)
mL/hour
Explanation & Rationale
Step 1 is (2 grams/hour ÷ 20 grams) × 500 mL. Step 2 is (2 ÷ 20) × 500. Step 3 is 0.1 × 500. The final calculated answer is 50 mL/hour.
