Final answer:
To calculate the infusion rate, total IV fluid for a day is first determined, followed by the total time to administer it. In an ideal situation, the rate would be 300mL/hr. In a continuous 24hr iv run, it would be about 12.5mL/hr.
Explanation:
To calculate the mL/hr, we'll first determine the total amount of IV fluid to be administered per day. As the IV is ordered to be given 1g three times a day, and it is supplied in 100mL, we have 300mL to administer in 24 hours. Next, we'll determine the time allotted for each dose, which is 20 minutes.
As there are three doses per day, that's a total run time of 60 minutes, or 1 hour. Thus, the infusion rate is 300mL/hr. However, keep in mind that this would mean the IV is running for only 1 hour a day, which may not be pertinent to reality.
In a more real-world scenario, if you were to spread the IV delivery across a full day (24 hours), the drip rate would be 300mL/24hr = 12.5mL/hr. Also, many healthcare settings may apply different protocols for these calculations, so always follow your institution's guidelines.
To calculate the milliliters per hour for the medication, we need to convert the 20 minutes to hours:
20 minutes = 20/60 = 1/3 hour
Now we can calculate the milliliters per hour by dividing the 100 mL by the 1/3 hour:
100 mL / (1/3 hour) = (100 mL) / (1/3) = 300 mL/hour
Therefore, you should set the controller to 300 mL per hour.
