A nurse is preparing to administer ceftriaxone 1 g via intermittent IV bolus over 30 min. Available is 1 g ceftriaxone sodium in 100 mL dextrose 5% in water. The nurse should set the pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the infusion rate in mL/hr for administering 1 g of ceftriaxone sodium in 100 mL of dextrose 5% in water over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. Since the time frame is 30 minutes, you convert this to hours by dividing by 60, which is 0.5 hours. Therefore, the calculation is 100 mL / 0.5 hours = 200 mL/hr. Rounding to the nearest whole number, the nurse should set the pump to deliver 200 mL/hr.
