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?

A.

1.55 L

B.

1.15 L

C.

1.25 L

D.

1.16 L

Answer and Explanation

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 A

Explanation

To find the rate in mL/hr, you need to calculate the following:

- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)

First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:

125 mg x 1000 = 125,000 mcg

Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:

125,000 mcg / 500 mL = 250 mcg/mL

Next, plug in the values into the formula for infusion rate:

Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 10.08 mL/h

Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.

Correct Answer is D

Explanation

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.
