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
