Order: 500 mL at 50 mL over 1 hour. The infusion started at 7 am. What time will the infusion end ?
To calculate the time when the infusion will end, we need to find out how many hours it will take to infuse the entire volume of 500 mL at a rate of 50 mL per hour.
First, we divide the total volume (500 mL) by the infusion rate (50 mL/hr) to find out how many hours it will take to infuse the solution:
500 mL รท 50 mL/hr = 10 hours
So, the infusion will take a total of 10 hours.
Adding this to the starting time of 7 am, we can calculate the end time.
Since the infusion started at 7 am, we will add 10 hours to get the end time:
7 am + 10 hours = 5 pm
Therefore, the infusion will end at 5 pm.
To determine the end time of the infusion, we need to find out how long it will take to infuse 500 mL at a rate of 50 mL over 1 hour.
Step 1: Calculate the infusion time for 1 mL:
Since the infusion rate is 50 mL over 1 hour, it will take 1 hour to infuse 1 mL.
Step 2: Calculate the total infusion time for 500 mL:
To infuse 500 mL at a rate of 1 mL per hour, it will take 500 hours.
Step 3: Calculate the end time of the infusion:
If the infusion started at 7 am, we need to add the total infusion time of 500 hours to the start time.
7 am + 500 hours = 7 am + 20 days and 20 hours = 7 am on the 21st day.
So, the infusion will end at 7 am on the 21st day.
