Question

Heparin 12, 000 units subcutaneous is prescribed. Stock ampoules contain 25, 000 units/ 5ml. What volume in ml should be drawn up?

Answer 1

Answer: The volume in ml that should be drawn is 2.4ml.

Explanation:

Heparin is an anticoagulant which is administered to prevent the formation of blood

clot in high risk patients. The high risk patients include those undergoing open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions. This medication can be administered subcutaneously ( that is, under the skin) by a health care provider. The exact dosage should be administered to avoid adverse effects.

From the question given,

In 5 ml of stock ampoules, there are 25,000 units.

To calculate how many millilitres will deliver 1 unit, divide by 25,000

5 ÷ 25000 = 0.0002

Therefore 0.0002 ml will deliver 1 Unit.

To calculate the volume that will deliver 12,000 units, multiply by 12,000.

Therefore,

12,000 × 0.0002 = 2.4mL

From the calculation, the volume in ml that should be drawn is 2.4ml
