Question 1 of 5
A nurse is preparing to administer cefazolin IVPB over 20 min. Available is cefazolin 1 g in 100 mL of dextrose 5% in water (D5W). The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the 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.)
Correct Answer: A
Rationale:
To calculate the IV infusion rate in drops per minute (gtt/min), we use the formula: (Volume to be infused in mL × drop factor) ÷ Time for infusion in minutes.
In this case, the volume to be infused is 100 mL, the drop factor is 15 gtt/mL, and the time for infusion is 20 minutes.
So, (100 mL × 15 gtt/mL) ÷ 20 min = 1500 ÷ 20 = 75 gtt/min.
Therefore, the correct answer is A: 75.
Other choices are incorrect because they do not correspond to the calculated rate based on the given parameters.
