Final answer:
To administer 5000 units of heparin from a vial with a concentration of 10,000 units/mL, the patient should be given 0.5 mL.
Step-by-step explanation:
To determine how many mL of heparin should be given to administer a dose of 5000 units, when the vial contains 10,000 units/mL, use the following calculation:
Dose required (units) ÷ Concentration (units/mL) = Volume to administer (mL)
In this case:
5000 units ÷ 10,000 units/mL = 0.5 mL
Therefore, the volume of the medication to be given to deliver 5000 units is 0.5 mL.
