Final answer:
To regulate the infusion to deliver 1000 ml of IV solution over 4 hours, you can calculate the gtts/minute using the formula gtts/min = (Volume to be infused in ml x gtts/ml) / Time in minutes. In this case, the nurse should regulate the infusion to deliver 250 gtts/minute.
Step-by-step explanation:
To regulate the infusion to deliver the specified amount of IV solution per minute, you can use the formula: gtts/min = (Volume to be infused in ml x gtts/ml) / Time in minutes
In this case, the volume to be infused is 1000 ml, the gtts/ml is 60, and the time is 4 hours, which is equal to 240 minutes. Plugging these values into the formula gives:
gtts/min = (1000 ml x 60) / 240 minutes = 250 gtts/min
Therefore, the nurse should regulate the infusion to deliver 250 gtts/minute.
