Ordered Ceftriaxone 1500 mg IV every 12 hours given over 30 minutes. Correct concentration: 40 mg/mL. At what rate do you set the IV pump to infuse over 30 minutes? Enter as a whole number and numeric value only.

Step 1 is: Calculate the volume of Ceftriaxone to administer. 1500 mg ÷ (40 mg ÷ 1 mL) = 1500 mg × (1 mL ÷ 40 mg) = 37.5 mL. Step 2 is: Calculate the infusion rate in mL/hr. 37.5 mL ÷ 30 min × 60 min ÷ 1 hr = 37.5 mL × 2 = 75 mL/hr. The infusion rate is 75.
