A client is prescribed 500 mL of a medication that is available in 2 mg/mL vials. How many mg of the medication should the client receive?

A.

250 mg

B.

500 mg

C.

1000 mg

D.

1500 mg

Answer and Explanation

The Correct Answer is C

To calculate the total amount of medication the client should receive, multiply the volume of the medication by its concentration:

500 mL x 2 mg/mL = 1000 mg

Therefore, the client should receive 1000 mg of the medication.

Correct Answer is C

Explanation

We can use the following formula to calculate the infusion rate:

Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg

First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg

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

Now we can plug in the values we have into the formula:

Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr

Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.

Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.

Correct Answer is B

Explanation

To calculate the flow rate in mL/hr for a continuous infusion, we need to divide the total volume to be infused by the total time of infusion, and then convert the units as necessary.

In this case, the total volume is 2.5 L, which is equivalent to 2500 mL (1 L = 1000 mL), and the total time is 15 hours.

Flow rate = Total volume to be infused / Total time of infusion Flow rate = 2500 mL / 15 hours

Flow rate = 166.67 mL/hr

Therefore, the flow rate for continuous infusion of 0.9% sodium chloride solution in this case is 166.67 mL/hr.
