Nebraska Methodist College NRS 450 Medication Titration Math Worksheet #2 A client was admitted to ICU with renal failure and has developed multi-organ system dysfunction. Dry weight was 60 kg. She is receiving the following medications: Nitroglycerine 50 mg/250 ml D5W at 20 mcg/min Dopamine 800 mg/250 ml D5W at 8 mcg/kg/min

1. What rate (mL/hr) do you expect the Nitroglycerine to be infusing? Record your answer using a whole number.

2. What rate (mL/hr) do you expect the Dopamine to be infusing? Record your answer using a whole number.

3. The primary care provider prescribes Amrinone loading dose of 0.75 mg/kg to be given over 3 minutes. What dose of Amrinone will the client receive? Record your answer using a whole number.

4. After the loading dose the nurse starts the Amrinone at 5 mcg/kg/min. Pharmacy sends Amrinone

250 mg/50 mL NS, what rate (mL/hr) will the nurse start the Amrinone infusion? Record your answer using one decimal place.

5. The primary care provider prescribes the Dopamine (from problem # 2) to be decreased to a renal

dose of 2 mcg/kg/min. What rate (mL/hr) will the nurse infuse the Dopamine? Record your answer using one decimal place.

6. The Amrinone is increased to 5 ml/hr. You know the maximum dose of Amrinone is 10 mcg/kg/min.

What is the maximum rate (mL/hr) you can infuse the Amrinone? Record your answer using one decimal place.

7. Two hours later, you need to notify the primary care provider of the client’s condition. The

Amrinone is now infusing at 17 mL/hr. What dose will you tell the primary care provider the client is receiving? Record your answer using one decimal place.

8. The client begins complaining of chest pain. The nurse increases the Nitroglycerine to 15 mL/hr. What dose (mcg/min) is she now receiving? Record your answer using a whole number.

9. Dopamine 400 mg in 250 mL D5W to infuse at 5 mcg/kg/min. The client’s weight is 200 pounds. How many mL/hour would this be on an infusion pump? Record your answer using a whole number.

10. A Dopamine drip (400mg in 250 mL of IV fluid) is infusing on an 80 kg client at 20 mL/hour. How

many mcg/kg/min are infusing for this client? Record your answer using one decimal place.

11. A Nitroglycerin drip is ordered for a client to control his chest pain. The concentration is 100 mg in 250 mL D5W. The order is to begin the infusion at 20 mcg/min. What is the rate you would begin the infusion on the infusion pump? Record your answer using a whole number.

12. A Nitroglycerin drip (100mg in 250 mL D5W) is infusing on your client at 28 mL/hour on the

infusion pump. How many mcg/min is your client receiving? Record your answer using one decimal place.

13. A procainamide drip is ordered (2gms in 250 mL D5W) to infuse at 4 mg/min. The patient weighs 165 pounds. Calculate the drip rate in mL/hour for which the infusion pump will be set at. Record your answer using a whole number.
