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

A.

20 hours

B.

10 hours

C.

15 hours

D.

75 hours

Answer and Explanation

The Correct Answer is A

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get:

Time = 1.5 L / 75 mL/hr Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

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

Correct Answer is C

Explanation

The patient is ordered to receive 0.15 mg/kg of Zofran over 15 minutes. The patient weighs 176 lb, which is equivalent to 80 kg. To calculate the total amount of Zofran the patient should receive, multiply the weight by the dosage:

80 kg x 0.15 mg/kg = 12 mg

The Zofran arrives from the pharmacy mixed in 50 mL of normal saline, which means there is 12 mg of Zofran in 50 mL of solution. To calculate how many milliliters per hour the nurse should set the IV pump, we can use the following formula:

50 mL / 0.25 hour = X mL per hour X = 200 mL per hour

Therefore, the nurse should set the IV pump to deliver 200 mL of Zofran per hour to the patient.

Correct Answer is B

Explanation

To calculate the infusion rate in mL/hr, we need to divide the total volume to be infused by the time for infusion and convert the units appropriately.

First, we need to convert the time of infusion from hours to minutes, since most IV pumps use minutes as the time unit.

2 hours x 60 minutes/hour = 120 minutes Next, we can calculate the infusion rate:

500 mL ÷ 120 minutes = 4.17 mL/minute

To convert mL/minute to mL/hour, we multiply by 60:

4.17 mL/minute x 60 minutes/hour = 250 mL/hour

Therefore, the correct answer is B. 250 mL/hr. The nurse should set the IV pump to deliver the LR infusion at a rate of 250 mL/hr to infuse 500 mL over 2 hours.
