A patient is ordered 5 mg of IV Lopressor (metoprolol tartrate) to be administered over 60 seconds. The concentration is 1 mg/1 mL.
How many milliliters per minute should the nurse administer to the patient?

0.008 mL

1 mL

5 mL

300 mL

Answer and Explanation

The Correct Answer is C

The patient is ordered to receive 5 mg of Lopressor over 60 seconds, which is equivalent to 1 minute. The concentration of Lopressor is 1 mg/1 mL, which means there is 1 mg of Lopressor in 1 mL of solution. To calculate how many milliliters per minute the nurse should administer, we can use the following formula:

5 mg / 1 mg per 1 mL = X mL X = 5 mL per minute.

Correct Answer is C

Explanation

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.

A. 0.65 mL/hr B. 9.6 mL/hr C. 10.1 mL/hr D. 14.8 mL/hr

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.
