A nurse is caring for a client who is 1 day postoperative following a total hip arthroplasty and is receiving heparin subcutaneously. Which of the following adverse effects of the medication should the nurse report to the provider?

Explanation C. Epistaxis Heparin is an anticoagulant medication used to prevent blood clot formation. One of the potential adverse effects of heparin therapy is bleeding. Epistaxis, or nosebleeds, can be a sign of abnormal bleeding and should be reported to the provider for further evaluation and adjustment of the treatment plan if necessary. Weight gain in (option A) is not a common adverse effect of heparin. Weight gain can be caused by various factors, but it is not directly related to heparin administration. Bradycardia (slow heart rate) in (option B) is not a common adverse effect of heparin. Bradycardia can be caused by other factors unrelated to heparin therapy and should be evaluated separately. Anorexia (loss of appetite) in (option D) is not typically associated with heparin therapy. Anorexia can have various causes, but it is not directly linked to heparin administration. Therefore, the nurse should report the occurrence of epistaxis (option C) to the healthcare provider as a potential adverse effect of heparin therapy in the client.
