Simulated
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 ml- via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is I5 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.)
Correct answer
A
Rationale
To calculate the IV infusion rate, first, convert the infusion time to minutes (30 min). Then, calculate the total volume to be infused (100 mL). Next, determine the total number of drops needed (15 gtt/mL x 100 mL) = 1500 drops. Finally, divide the total drops by the infusion time in minutes (1500 drops / 30 min) = 50 gtt/min. This is why choice A (50) is correct. Choices B, C, and D are incorrect as they do not match the calculated infusion rate.
