A nurse is preparing to administer ceftriaxone 1 g via IV bolus over 30 min. Available is 1 g ceftriaxone sodium in 100 mL dextrose 5% in water (D5W). 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 mL/hr rate for administering 1 g of ceftriaxone over 30 minutes, we first convert the 30 minutes to hours (30 min ├À 60 min/hr = 0.5 hr). Then, we use the formula: Rate = Dose ├À Time. The dose is 1 g, so the rate = 1 g ├À 0.5 hr = 2 g/hr. Since we have 1 g in 100 mL, the rate in mL/hr would be 100 mL ├À 2 g/hr = 50 mL/hr. Therefore, the correct answer is B (200 mL/hr). Choices A, C, and D are incorrect as they do not align with the calculated rate of 200 mL/hr based on the given information and calculations.
