A nurse is preparing to administer Lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor in the manual IV tubing is 60 gtt/mL. The nurse should set the flow rate to deliver how many gtts/min?
Correct answer
C
Rationale
The correct answer is C: 120 gtt/min. To calculate the infusion rate in gtts/min, first convert the prescribed rate of 120 mL/hr to gtts/hr by multiplying it by the drop factor of 60 gtt/mL.
120 mL/hr * 60 gtt/mL = 7200 gtts/hr
Next, convert gtts/hr to gtts/min by dividing by 60 (since there are 60 minutes in an hour):
7200 gtts/hr / 60 min = 120 gtts/min
Therefore, the nurse should set the flow rate to deliver 120 gtts/min.
Choice A is incorrect as it is lower than the correct answer. Choice B is incorrect as it is also lower than the correct answer. Choice D is incorrect as it is higher than the correct answer.
