# Dosage Calculation (Heparin)

- 0Dec 28, '10 by YGPHNMHello nurses and student nurses..

I need some help figuring out the answer to a heparin problem. I'm coming up with an answer but I'm not quite sure if I have it correct. Please guide me...

4. ORDER: Give a heparin drip of 25, 000 units in 500 cc D5W at 9 cc/hr

Heparin: Prevents recurrence of thrombosis; use with tPa. Adjust dose to keep

APTT at 1.5-2.0 times control. ASA often given with heparin. Protamine reverses

heparin. Watch for bleeding.

Available is 10,000 units/1 cc

QUESTION: How many cc of heparin would be added to the IV?

Would this formula work?

Desired amount = cc

Conc in sum

QUESTION: What is the concentration of heparin per cc in the IV bag after

it’s mixed?

QUESTION: How many units of heparin per hour is the patient receiving?

QUESTION: If the MD ordered the drip increased by 200 units/hr, whatwould the IV rate be (cc/hr)?

needed 25,000 units of Heparin on hand 10,000 unit /1cc

so 10,000units : 1 cc :: 25,000units : x

10,000:1::25,000:x

1 x 25,000 = 25,000

X x 10,000 = 10,000x

10,000x / 10,000 = x

25,000 / 10,000 = 2.5 so x = 2.5cc

2.5 cc of hep will be added to iv

25,000/2.5cc cocentrate

**25,000 units/ 10,000 units/ml =****2.5ml**

**question: what is the concentration of heparin per cc in the iv bag after**

it’s mixed?

**25,000units/500ml =****50units/ml**

**question: how many units of heparin per hour is the patient receiving?**

**answer is in the order; 9ml/hr.**

**question: if the md ordered the drip increased by 200 units/hr, what**

**would the iv rate be (cc/hr)?**

**here is how you solve this one. your original order is for 9ml/hr, right? that means you are running 450 units of heparin per hour (50 units/ml x 9ml). now the md ordered an additional 200 units per hour for a total of 650 units/hr. so: 650units/50 units per ml = 13ml/hr.**
