ATI Pharmocology Exam Fletcher NRSG 106 Questions

Extract:


Question 1 of 5

A nurse is caring for a client who is postoperative following an appendectomy and is prescribed Ds lactated Ringer's at 150 mL/hr by continuous IV infusion for 12 hr. The drop factor of the manual IV tubing is 20 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 determine the correct rate of IV infusion in drops per minute (gtt/min), first calculate the total volume to be infused in 12 hours: 150 mL/hr x 12 hr = 1800 mL.
Then convert this to drops using the drop factor of 20 gtt/mL: 1800 mL x 20 gtt/mL = 36000 gtt. Finally, divide the total drops by the total time in minutes (12 hr x 60 min/hr = 720 min): 36000 gtt รท 720 min = 50 gtt/min (rounded to the nearest whole number).
Therefore, the correct answer is A: 50 gtt/min. Other choices are incorrect because they do not result from the accurate calculation based on the prescribed infusion rate and drop factor.
