A nurse, via an infusion pump, sets up an infusion rate ratio of 2.75 mL/min for a continuous intravenous (IV) fluid for 7 hours.
What is the total volume of IV fluid being infused, in liters?
1.55 L
1.15 L
1.25 L
1.16 L
The Correct Answer is D
To answer this question, we need to calculate the infusion rate in mL per hour, then multiply it by the total time in hours, and finally divide it by 1000 to get the volume in litres.
The infusion rate in mL per hour is the amount of fluid that is given to a patient over a period of time. It can be calculated by dividing the total volume of fluid in mL by the total time in hours². In this case, the infusion rate is:
2.75 mL/min × 60 min/h = 165 mL/h
The total volume of fluid in mL is the infusion rate multiplied by the total time in hours. In this case, the total volume is:
165 mL/h × 7 h = 1155 mL
The volume in litres is the volume in mL divided by 1000. In this case, the volume in litres is:
1155 mL / 1000 = 1.16 L
Therefore, the correct answer is d. 1.16 L.

Correct Answer is D
Explanation
One tablespoon is equal to **14.7867648 milliliters**¹²³⁴. To convert tablespoons to milliliters, you can multiply the value in tablespoons by 14.7867648. For example, 1 tablespoon x 14.7867648 milliliters = 14.7867648 milliliters.
Therefore, to convert 1 tablespoon of mouthwash to milliliters, you can multiply 1 by 14.7867648. The answer is **14.7867648 milliliters**. This is the amount of mouthwash that a patient uses in 1 tablespoon.
Correct Answer is A
Explanation
The IV infusion will be completed at 13:20.
This answer is correct because it is based on a simple division and addition calculation. The nurse can divide the total volume of the infusion by the infusion rate to get the duration of the infusion in hours, as follows:
1000 mL / 250 mL/hr = 4 hr
Therefore, the infusion will take 4 hours to complete. The nurse can add 4 hours to the start time of the infusion to get the end time, as follows:
09:20 + 4:00 = 13:20
Therefore, the IV infusion will be completed at 13:20.
