Passage / Scenario
Administer ceftriaxone 1 g via intermittent IV bolus over 30 min. Available is 1 g ceftriaxone sodium in 100 mL dextrose 5% in water.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.)
Correct answer
A
Rationale
To calculate the mL/hr rate for IV infusion, we first need to determine the total volume (mL) to be infused over 30 min. Ceftriaxone 1 g in 100 mL dextrose 5% solution = 100 mL. Since the total dose is 1 g, the total volume to be infused is 100 mL. To find the mL/hr rate, we divide the total volume by the infusion time in hours (30 min = 0.5 hr). 100 mL / 0.5 hr = 200 mL/hr. Therefore, the nurse should set the pump to deliver 200 mL/hr. Other choices are incorrect because they do not follow the correct calculation process or are not based on the given information.
