At 9:00 a.m. a nurse starts an intravenous (IV) infusion for a client at the rate of 120 mL/hr. If the volume of the fluid is 0.75 L, when will this infusion be completed?

3:01 p.m.

3:15 p.m.

3:25 p.m.

3:45 p.m.

Answer and Explanation

The Correct Answer is B

We can use the formula for calculating infusion time:. Infusion time = Total volume / Infusion rate.

First, we need to convert the volume of the fluid from liters to milliliters:.

0.75 L = 750 mL.

Next, we can plug in the values we have:. Infusion time = 750 mL / 120 mL/hr.

Infusion time = 6.25 hours.

Since the infusion was started at 9:00 a.m., we can add 6.25 hours to determine when the infusion will be completed:.

9:00 a.m. + 6.25 hours = 3:15 p.m..

Therefore, the infusion will be completed at 3:15 p.m.

Correct Answer is B

Explanation

If one dose of medication is 25 mg and each vial contains 50 mg of medication, then each vial contains two doses..

To calculate the number of vials required for 5 days of treatment, we first need to calculate the total number of doses required. Since the client requires two injections per day, the total number of doses required for 5 days would be:.

Total number of doses = 2 doses/day x 5 days. Total number of doses = 10 doses.

Since each vial contains two doses, we need a total of 10/2 = 5 vials for 5 days of treatment..

Therefore, the nurse would need 5 vials of the medication for 5 days of treatment for the client.

A. 50 mL B. 100 mL C. 250 mL D. 500 mL

Correct Answer is C

Explanation

To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..

So the nurse should add 250 mL of water to the formula to dilute it to half strength.
