A client is receiving an intravenous infusion of 1.5 L of saline solution at a rate of 75 mL/hr.
How many hours will it take to finish the infusion at the current rate?

A.

10 hours

B.

7.5 hours

C.

20 hours

D.

15 hours

Answer and Explanation

The Correct Answer is C

To find the hours to finish the infusion, you need to calculate the following:

- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)


First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:
 
1.5 L x 1000 = 1500 mL


Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:


Time (h) = Total volume (mL) / Infusion rate (mL/h)


Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:


Time (h) = 1500 mL / 75 mL/h


Simplify and solve for the time:


Time (h) = 20 h


Therefore, it will take **20 hours** to finish the infusion at the current rate.

Correct Answer is D

Explanation

The safe dose of ertapenem for children is **15 mg/kg** twice daily, with a maximum dose of **500 mg** per dose. Therefore, the correct answer is **d) 15 mg/kg twice daily**. Ertapenem is a carbapenem antibiotic that is used to treat various infections caused by susceptible bacteria.

Correct Answer is B

Explanation

To find the rate in mL/hr, you need to use the formula for infusion rate:


Infusion rate (mL/h) = Total volume (mL) / Time (h)


Since the total volume is 500 mL and the time is 2 hours, plug in these values into the formula:


Infusion rate (mL/h) = 500 mL / 2 h


Simplify and solve for the infusion rate:


Infusion rate (mL/h) = 250 mL/h


Therefore, the nurse should set the IV pump to deliver **250 mL/h** to infuse LR 500 mL over 2 hours.
