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. 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.
