Correct Answer is A

Explanation

To calculate the total amount of heparin, we need to multiply the infusion rate by the time and then by the concentration of heparin in the IV bag. From 9:00 a.m. to 11:00 a.m., the infusion rate was 12 mL/hr, so the amount of heparin infused in this period was 12 mL/hr x 2 hours x 100 units/mL = 2400 units.

From 11:00 a.m. to 2:00 p.m., the infusion rate was 10 mL/hr, so the amount of heparin infused in this period was 10 mL/hr x 3 hours x 100 units/mL = 3000 units. The total amount of heparin infused from 9:00 a.m. to 2:00 p.m. was 2400 units + 3000 units = 5400 units.

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.
