A client has a prescription for heparin 5000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client’s medication drawer. Which action should the nurse implement?

Choice A reason:Requesting a prescription to change the route of administration and use the available heparin is not appropriate. Low molecular weight heparin (LMWH) and unfractionated heparin (UFH) are not interchangeable on a unit-for-unit basis. They have different pharmacokinetics and dosing requirements. Changing the route without proper guidance can lead to incorrect dosing and potential complications.Choice B reason:Calculating and administering the equivalent dose of the available low molecular weight heparin is incorrect. LMWH and UFH have different dosing protocols and are not directly interchangeable. Administering LMWH instead of UFH without proper conversion and guidance can result in inappropriate anticoagulation.Choice C reason:Diluting the available heparin in 250 ml of normal saline solution prior to IV administration is not appropriate. The prescription specifies heparin 5000 units IV STAT, which indicates an immediate need for intravenous administration. Diluting and administering it in this manner does not align with the urgency of the order.Choice D reason:Advising the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately is the correct action. This ensures that the client receives the prescribed medication in the correct form and dosage as ordered by the healthcare provider. It is crucial to follow the specific instructions for heparin administration to ensure patient safety and effective anticoagulation.
