A nurse is preparing to administer cefazolin 1 g by intermittent intravenous (IV) bolus over 30 minutes. Available is cefazolin 1 g in 100 mL dextrose 5% in water (D5W). The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero. Only enter numbers and decimals. Do not enter any letters in your answer.)

Answer and Explanation

The Correct Answer is ["33"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) ) x Drop factor (gtt/mL)

First, calculate the total volume to be infused:

100 mL / 30 min = 3.33 mL/min

Then, multiply the volume per minute by the drop factor:

3.33 mL/min x 10 gtt/mL = 33.3 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 33 gtt/min.
