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?

20 hours

10 hours

15 hours

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 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. 10g B. 20 g C. 30 g D. 40 g

Correct Answer is D

Explanation

To calculate the amount of magnesium sulfate to be added to the normal saline, we can use the formula:

Concentration = Dose / Volume Plugging in the given values, we get:

Concentration = 2 g / 50 mL Simplifying, we get:

Concentration = 0.04 g/mL

To find the amount of magnesium sulfate needed for 1000 mL of normal saline, we can multiply the concentration by the volume:

Amount = Concentration × Volume Amount = 0.04 g/mL × 1000 mL Amount = 40 g

Therefore, 40 g of magnesium sulfate must be added to 1000 mL of normal saline to provide the ordered infusion.
