A nurse is caring for a client who is receiving an IV infusion of heparin. Which of the following findings should indicate to the nurse the client is at risk for hemorrhage? (Select all that apply.)

A. "Thrombocytopenia": Heparin can cause a decrease in platelet count, known as heparin-induced thrombocytopenia (HIT), which increases the risk of bleeding and hemorrhage. Thrombocytopenia is a key indicator of increased bleeding risk in clients receiving heparin. B. "Neutropenia": While neutropenia can be an adverse effect of some medications, it is not directly associated with an increased risk of hemorrhage due to heparin. It does not directly impact the blood clotting process. C. "Hypokalemia": Low potassium levels are not directly related to an increased risk of hemorrhage due to heparin. Hypokalemia may lead to other complications, but it does not specifically indicate bleeding risk. D. "Hyperglycemia": Heparin can sometimes cause elevated blood glucose levels, especially in long-term use, but hyperglycemia does not directly increase the risk of hemorrhage. E. "Fever": Fever can indicate infection or inflammation but is not a direct sign of hemorrhage. It is more related to potential infection or other inflammatory processes, not bleeding from heparin. F. "Dark stools": Dark stools can indicate gastrointestinal bleeding, a common sign of hemorrhage, especially in clients receiving anticoagulant therapy like heparin. It is a significant sign to monitor for and report immediately.
