The doctor prescribes ceftizoxime 1 g IVPB every 12 hours. If it must be infused over 30 minutes, what is the calculated mL/hr rate if it is in 50 mL NS?

To determine the correct infusion rate, we first need to calculate how many mL need to be infused per hour given that the total volume is 50 mL and the total infusion time is 30 minutes.

Since the medication is prescribed to be infused over 30 minutes, we can convert that time into hours to make the calculation easier. Fifty mL needs to be infused in half an hour (0.5 hours).

Next, we need to find the rate of infusion in mL per hour. The calculation is straightforward:

1. The total volume of the solution is 50 mL.

2. The infusion time is 0.5 hours.

To find the rate per hour, we need to divide the total volume by the infusion time in hours:

Infusion Rate (mL/hr) = Total Volume (mL) / Infusion Time (hr)

Infusion Rate (mL/hr) = 50 mL / 0.5 hr

Infusion Rate (mL/hr) = 100 mL/hr

However, the infusion occurs over a shorter time frame than a full hour, specifically over 30 minutes. This means that while the calculated infusion rate is 100 mL/hr for the entirety of
