While all the listed interventions are relevant to the care of a patient with aplastic anemia, the nursing process dictates that physiological integrity and safety take precedence. In this scenario, preventing catastrophic bleeding is the most immediate threat to life. Why Option 3 is the Highest Priority Option 3, “Assess for signs of internal bleeding and avoid invasive procedures,” directly addresses the most lethal complication of a platelet count this low. The primary clinical danger of severe thrombocytopenia, as highlighted in the context of haematological disorders, is the risk of severe or life-threatening bleeding, which can occur spontaneously without any trauma [1]. This risk is not merely theoretical; it is a well-documented adverse event that can rapidly become fatal, particularly when platelet counts fall below 10,000/mm³. The rationale for avoiding invasive procedures is a direct application of this principle. Any breach in skin or mucosal integrity—such as intramuscular injections, venipuncture in non-compressible sites, or rectal procedures—can precipitate uncontrolled hemorrhage. Assessment is equally critical; a nurse must vigilantly monitor for subtle signs of internal bleeding, including changes in mental status (intracranial hemorrhage), flank pain (retroperitoneal bleeding), or guaiac-positive stools (gastrointestinal bleeding). This proactive surveillance is the cornerstone of preventing a minor bleed from evolving into a life-threatening event. Analysis of Other Options - Option 1: Encouraging a soft-bristled toothbrush and electric razor is an important safety measure to prevent mucosal and skin bleeding. However, it is a secondary, preventative intervention. The priority is to first assess the patient's current status for any active, occult bleeding and to halt any planned invasive procedures that could cause immediate harm. This option is a component of the broader safety plan but does not constitute the highest priority action. - Option 2: Monitoring for infection and implementing neutropenic precautions is a high priority in aplastic anemia due to the risk of neutropenia. However, the question stem specifically highlights the critical lab value of severe thrombocytopenia (8,000/mm³). While infection is a significant long-term risk in bone marrow failure syndromes like aplastic anemia, which is marked by pancytopenia , the immediate, life-threatening risk from a platelet count this low is fatal hemorrhage. The nursing priority must align with the most acute and life-threatening clinical data presented. - Option 4: Administering iron supplements is an intervention for iron-deficiency anemia, which is not the underlying pathophysiology of aplastic anemia. Aplastic anemia is a bone marrow failure disorder characterized by pancytopenia, not by a lack of iron stores . In fact, patients with aplastic anemia often require multiple red blood cell transfusions and are at risk for iron overload, making iron supplementation potentially harmful. This intervention is not indicated and does not address the critical problem of thrombocytopenia. Clinical Reasoning and Pathophysiology The clinical reasoning here is rooted in the pathophysiology of thrombocytopenia. Platelets are essential for primary hemostasis, forming the initial plug at sites of vascular injury. When the count drops to 8,000/mm³, this mechanism is severely compromised, and the patient is susceptible to spontaneous bleeding, including devastating intracranial hemorrhage. The evidence suggests that even with prophylactic platelet transfusions, the risk of bleeding remains a significant concern, which is why adjunct therapies like antifibrinolytics are investigated to stabilize any clots that do form [1]. The nurse’s role is to prevent any action that could disrupt the body’s fragile hemostatic balance, making the avoidance of invasive procedures and the astute assessment for occult bleeding the most critical interventions. In low-resource settings where immediate access to platelet transfusions may be limited, as noted in case reports of severe aplastic anemia, these conservative, protective nursing measures become even more vital to patient survival .References (research sources) - [1]Antifibrinolytics (lysine analogues) for the prevention of bleeding in people with haematological disorders.Research articleChampaneria R, Estcourt LJ, Geneen L, Brunskill SJ, Dorée C, Stanworth SJ, Desborough MJ.

A platelet count of 8,000/mm³ is critically low, requiring immediate assessment for internal bleeding. The highest priority intervention is to assess for signs of internal bleeding (e.g., mental status changes, hematuria, melena) and strictly avoid all invasive procedures. CautionAvoid rectal procedures, intramuscular injections, and venipuncture in non-compressible sites. Apply prolonged pressure after any necessary venipuncture. Monitor for subtle signs of intracranial hemorrhage. ## 핵심 개념 - **Severe Thrombocytopenia** — A platelet count below 10,000/mm³, characterized by a high risk of spontaneous and life-threatening internal hemorrhage. - **Aplastic Anemia** — A bone marrow failure disorder resulting in pancytopenia, including anemia, leukopenia, and thrombocytopenia. - **Bleeding Precautions** — Nursing interventions to prevent hemorrhage, such as avoiding invasive procedures, using soft-bristled tools, and monitoring for signs of internal bleeding. ## 같은 주제 문제 - [A nurse is assessing a 28-year-old patient with suspected aplastic anemia.
