Nitroglycerin 125 mg diluted in 500 mL D5W (dextrose 5% in water) is infusing at a rate of 42 mcg/minute for a patient with chest pain. What rate (in mL/hr) should the nurse program into the IV pump to deliver this dose?

Round your answer to the nearest tenth.

0.65 mL/hr

9.6 mL/hr

10.1 mL/hr

14.8 mL/hr

Answer and Explanation

The Correct Answer is C

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

Step 1: Determine the dosage ratio. 60 mg (ordered) ÷ 70 mg (available) = 0.8571 (rounded to 4 decimal places)

Step 2: Calculate the volume to administer. 0.8571 × 75 mL (available) = 64.2857 mL (rounded to 4 decimal places)

Step 3: Round to the nearest whole number. 64.2857 mL rounds to 64 mL

So, the nurse should administer 64 mL to the patient.

The correct answer is B. 64 mL.

The correct answer is B. 64 mL.

A. 11:20 B. 12:20 C. 13:20 D. 14:20

Correct Answer is C

Explanation

To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.

Total infusion time = Total volume to be infused / Infusion rate.

In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.

Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.

Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.
