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.

A lozenge is a type of medication that is designed to dissolve slowly in the mouth, usually to treat sore throat, cough, or oral infections. It should not be divided or crushed for administration because it may alter its effectiveness, taste, or absorption. It should also not be swallowed whole because it may cause choking or irritation.
A capsule is a type of medication that consists of a gelatin shell enclosing a powder or liquid. It can be opened and sprinkled on soft food or mixed with water for administration unless it is an extended-release or enteric-coated capsule.
A scored tablet is a type of medication that has a groove or indentation on its surface to facilitate breaking into equal halves or quarters. It can be divided along the score line for administration unless it is an extended-release or enteric-coated tablet.
An unscored tablet is a type of medication that does not have a groove or indentation on its surface. It can be crushed or cut into smaller pieces for administration unless it is an extended-release or enteric-coated tablet.
Correct Answer is B
Explanation
Step 1 is Convert pounds to kilograms 110 lb ÷ 2.2 = 50 kg
Step 2 is Calculate dose in micrograms per minute 50 kg × 200 micrograms = 10,000 micrograms/min
Step 3 is Convert micrograms to milligrams 10,000 micrograms ÷ 1000 = 10 mg/min
Step 4 is Convert mg/min to mg/hr 10 mg × 60 = 600 mg/hr
Step 5 is Determine concentration of esmolol in mg/mL 2.5 grams × 1000 = 2500 mg 2500 mg ÷ 250 mL = 10 mg/mL
Step 6 is Calculate infusion rate in mL/hr 600 mg/hr ÷ 10 mg/mL = 60 mL/hr
