A nurse is reviewing the laboratory results of a client who is receiving intravenous unfractionated heparin.The nurse notes that the client’s activated partial thromboplastin time (aPTT) is 120 seconds.What are the appropriate nursing actions in this situation? Select all that apply.*.

Choice A rationale:Stopping the heparin infusion immediately is essential when the client's aPTT is significantly elevated (in this case, 120 seconds). A prolonged aPTT indicates a higher risk of bleeding, and discontinuing the heparin infusion is a crucial step in preventing further bleeding.Choice B rationale:Administering protamine sulfate is necessary when a client on heparin therapy experiences excessive bleeding or if the aPTT is significantly elevated. Protamine sulfate acts as a heparin antagonist and can reverse the anticoagulant effects of heparin.Choice C rationale:Notifying the healthcare provider of the significantly prolonged aPTT is essential because it may indicate a need for adjustments in the heparin dosage or therapy. The provider can determine the appropriate course of action based on the client's clinical condition.Choice D rationale:Drawing a prothrombin time (PT) and international normalized ratio (INR) level is not necessary in this situation. PT and INR are more relevant parameters when assessing clients on warfarin therapy, not heparin.Choice E rationale:Monitoring the client for signs and symptoms of bleeding is crucial when the aPTT is prolonged, as it indicates a higher risk of bleeding. This action allows for early detection and intervention to prevent complications.
