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.)
The Correct Answer is ["200"]
To calculate the infusion rate in mL/hr for administering ceftriaxone 1 g via intermittent IV bolus over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. In this case, the total volume of the solution is 100 mL, and the time frame is 0.5 hours (since 30 minutes is half an hour). Therefore, the calculation would be 100 mL / 0.5 hours = 200 mL/hr.

Correct Answer is ["21"]
Explanation
Total volume in mL: 3000 mL
Time in hours: 24 hours
Total volume to be infused in minutes: We need to convert hours to minutes. There are 60 minutes in 1 hour. Therefore, total time in minutes = 24 hours * 60 minutes/hour = 1440 minutes
Drop factor: 10 gtt/mL
Rate in mL/min: We can divide the total volume (mL) by the total time (minutes) to find the flow rate in mL per minute. Rate (mL/min) = 3000 mL / 1440 minutes = 2.08 mL/min (rounded to two decimal places)
Rate in gtt/min: To find the rate in gtt/min, multiply the rate in mL/min by the drop factor. Rate (gtt/min) = 2.08 mL/min * 10 gtt/mL = 20.8 gtt/min
Rounding the answer to the nearest whole number: 20.8 gtt/min rounds off to the nearest whole number to 21 gtt/min.
