Question 1 of 5
A nurse is caring for a client who is postoperative following an appendectomy and is prescribed D, 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: The correct answer is A: 4 gtt/min.
To calculate the drip rate, we first convert the prescribed mL/hr to mL/min (150 mL/hr รท 60 min = 2.5 mL/min).
Then, we multiply the mL/min by the drop factor (2.5 mL/min x 20 gtt/mL = 50 gtt/min).
Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min, which rounds to 4 gtt/min as per the question. Other choices are incorrect as they do not follow the correct calculation steps or do not round to the nearest whole number.
