Question 1 of 5
A nurse is caring for a client who is postoperative following an appendectomy and is prescribed D5 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: 50 gtt/min
Rationale:
To calculate the drops per minute (gtt/min) for the IV infusion, we first need to determine the total volume to be infused over 12 hours. Given the rate is 150 mL/hr for 12 hours, the total volume is 150 mL/hr x 12 hr = 1800 mL. Next, we convert this volume to drops using the drop factor of 20 gtt/mL. So, 1800 mL x 20 gtt/mL = 36000 gtt. Finally, we divide the total drops by the total time in minutes (12 hr x 60 min/hr) to get the rate in gtt/min: 36000 gtt / (12 hr x 60 min/hr) = 50 gtt/min.
Therefore, the correct answer is 50 gtt/min. Other choices are incorrect due to incorrect calculations or misinterpretation of the question.
