Question 1 of 5
A nurse is caring for a client who is postoperative following an appendectomy and is prescribed lactated Ringer's at 150 mL/hr by continuous IV infusion. The drop factor of the 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: B
Rationale:
To calculate the IV infusion rate in drops per minute (gtt/min), we first need to convert the prescribed rate from mL/hr to drops per minute. Given that the IV tubing has a drop factor of 20 gtt/mL, we can use the following formula: mL/hr x drop factor / 60 = gtt/min.
In this case, 150 mL/hr x 20 gtt/mL / 60 = 50 gtt/min.
Therefore, the correct answer is B (50).
Choice A (40) is incorrect because the calculation is not accurate.
Choice C (60) is incorrect as it does not consider the drop factor.
Choice D (70) is incorrect as it is not the rounded-up value of the calculated rate.
