Which nursing intervention is most important to prevent complications associated with repeated transfusions? ## 보기 1. Monitor for signs of hemolytic reactions during each transfusion 2. Assess for development of splenomegaly and abdominal distension 3. Administer iron chelation therapy as prescribed to prevent iron overload **✔ 정답** 4. Encourage increased dietary iron intake to support red blood cell production **정답: 3** ## 해설 Iron chelation therapy is priority to prevent iron overload complications from chronic transfusions. Other interventions are important but do not address the main long-term risk. ## 심화 해설 Understanding the Priority: Long-Term Complication Prevention In clients with beta-thalassemia major (BTM), a genetic defect in hemoglobin production leads to severe anemia, making regular blood transfusions a life-sustaining necessity. However, the human body lacks an active physiologic mechanism to excrete the excess iron introduced with each unit of transfused red blood cells. Over time, this iron accumulates in vital organs—a condition known as transfusional iron overload [2]. While acute transfusion reactions are important to monitor for during the infusion, the most critical long-term nursing intervention is preventing the insidious and potentially fatal damage caused by iron deposition in the heart, liver, and endocrine glands [1]. Why Iron Chelation Therapy is the Priority Without intervention, the accumulated iron generates free radicals, leading to oxidative stress and organ fibrosis. This results in life-threatening complications such as cardiomyopathy, liver cirrhosis, and diabetes mellitus [2]. Iron chelation therapy (ICT) works by binding to the excess iron in the body, allowing it to be excreted in urine or feces. Administering ICT as prescribed is the only way to prevent or delay this irreversible end-organ damage, making it the cornerstone of chronic management for transfusion-dependent thalassemia [1, 3]. Analysis of Other Options To clarify why the other options are not the most important intervention in this context, consider the following distinctions: - Option 1 (Monitor for hemolytic reactions): While essential during every transfusion, this is an acute safety measure. It does not address the cumulative, long-term risk that defines the chronic care of a client requiring repeated transfusions over a lifetime. - Option 2 (Assess for splenomegaly): Splenomegaly is a common finding in BTM due to extramedullary hematopoiesis and red blood cell destruction. While important to assess, it is a complication of the disease process itself, not the primary, preventable consequence of the transfusion therapy. - Option 4 (Encourage increased dietary iron): This intervention is contraindicated. Clients with BTM already have a pathologic iron-loading state from transfusions. Adding dietary iron would dangerously accelerate the development of iron overload and organ toxicity [2]. Clinical Application and Adherence Challenges The effectiveness of ICT hinges on consistent adherence, which can be challenging due to the demanding nature of the therapy and its side effects [1]. A systematic review highlights that poor adherence directly correlates with adverse health outcomes, including elevated serum ferritin levels and increased organ iron concentration [3]. As a nurse, your role extends beyond simply administering the medication; it involves thorough education on the purpose of the therapy, monitoring for side effects, and assessing for barriers to adherence to ensure the client is protected from the devastating effects of iron overload [1, 3]. The goal of therapy is to maintain iron levels within a safe range, preventing the severe cardiac and hepatic complications that remain a leading cause of mortality in this population [2, 4].References (research sources) - [1]Interventions for improving adherence to iron chelation therapy in people with sickle cell disease or thalassaemia.Research articleGeneen LJ, Dorée C, Estcourt LJ.

Each unit of packed red blood cells contains approximately 200–250 mg of iron, which the body cannot actively excrete. Without intervention, iron deposition in the heart, liver, and endocrine organs leads to fatal cardiomyopathy, cirrhosis, and diabetes mellitus. 1. Iron Chelation Therapy (ICT) Management - **Timing:** ICT is typically initiated after 10–20 transfusions or when serum ferritin levels consistently exceed 1,000 ng/mL. - **Agents:** Common chelators include deferoxamine (subcutaneous or intravenous infusion), deferasirox (oral), and deferiprone (oral). Adherence is critical; assess for barriers to administration. - **Monitoring:** Regularly monitor serum ferritin, liver iron concentration (LIC) via MRI, and cardiac T2* MRI to titrate therapy and prevent toxicity from the chelating agents themselves (e.g., sensorineural hearing loss, renal impairment, agranulocytosis). 2. Transfusion Safety and Acute Monitoring - **Pre-transfusion:** Verify the provider's order, ensure type and crossmatch are completed, and obtain informed consent. Assess baseline vital signs, heart, and lung sounds. - **During Transfusion:** Remain with the patient for the first 15 minutes, the period of highest risk for an acute hemolytic or allergic reaction. Monitor vital signs per protocol. Report any signs of fever, chills, flank pain, or dyspnea immediately. 3. Patient and Family Education - **Dietary Counseling:** Educate the patient to avoid iron-rich foods (e.g., red meat, fortified cereals) and vitamin C supplements near meal times, as vitamin C increases iron absorption. Tea and dairy products can be consumed with meals to inhibit iron absorption. - **Signs of Iron Overload:** Teach the patient to report symptoms such as fatigue, joint pain, abdominal pain, palpitations, or signs of new-onset diabetes (polyuria, polydipsia). - **Infection Prevention:** Patients with iron overload are at increased risk for infections from siderophilic bacteria (e.g., Yersinia enterocolitica). Counsel on food safety and seeking prompt care for fever. 4. Multidisciplinary Care Coordination Collaborate with hematology, cardiology, endocrinology, and a registered dietitian to provide comprehensive surveillance for end-organ damage. Ensure the patient has an individualized transfusion and chelation plan, updated regularly based on laboratory and imaging results. ## 핵심 개념 - **Transfusional Iron Overload** — A condition caused by the accumulation of excess iron from repeated red blood cell transfusions, as the body lacks a mechanism to excrete it, leading to organ damage. - **Iron Chelation Therapy** — A treatment that uses agents to bind excess iron in the body, forming a complex that can be excreted in urine or feces to prevent or manage iron overload. ## 같은 주제 문제 - [A nurse is assessing a 25-year-old patient with beta-thalassemia major.
