A 60-year-old client receiving heparin therapy for deep vein thrombosis (DVT) reports unusual bruising and hematuria. Upon reviewing the client’s lab results, the nurse finds that the activated partial thromboplastin time (aPTT) is significantly elevated. Which interventions should the nurse perform next? Select all that apply. Administer protamine sulfate to reverse the effects of heparin if ordered. Reinforce client education about avoiding activities that could cause injury. Adjust the heparin dose to a lower level and recheck the aPTT in 6 hours. Monitor the client for further signs of bleeding and continue the current heparin dose. Hold the heparin infusion and notify the healthcare provider.
