A nurse is caring for a 45-year-old patient with aplastic anemia who has a platelet count of 12,000/mm³. Which nursing intervention should be the highest priority?

## 해설

With severe thrombocytopenia (platelet count 15,000/mm³), bleeding precautions are the highest priority to prevent life-threatening hemorrhage. Other interventions address infection or nutrition but are not immediate threats.

Understanding the Priority: The Critical Platelet Count

The patient's platelet count of 12,000/mm³ represents severe thrombocytopenia. A normal platelet count typically ranges from 150,000 to 400,000/mm³. When the count drops below 20,000/mm³, the risk of spontaneous and potentially life-threatening hemorrhage becomes a primary clinical concern. In the context of aplastic anemia, the bone marrow's failure to produce sufficient blood cells directly causes this profound deficit. The highest priority nursing intervention must therefore directly address the most immediate threat to the patient's physiological integrity, which is catastrophic bleeding.

Why Bleeding Precautions Are the Highest Priority

The correct answer is to institute bleeding precautions and monitor for signs of hemorrhage. This is grounded in the fundamental pathophysiology of aplastic anemia and the immediate dangers of severe thrombocytopenia. The provided case report by Damseh et al. powerfully illustrates this principle. It describes a patient whose initial presentation of undiagnosed aplastic anemia was a spontaneous hemoperitoneum from a ruptured ovarian cyst, a life-threatening bleeding event requiring emergency surgery [2]. This real-world example underscores that in aplastic anemia, even a minor or typical physiological event, such as ovulation and cyst formation, can escalate into a major hemorrhage due to the lack of platelets needed for hemostasis. Your clinical reasoning must connect the lab value (12,000/mm³) directly to this risk. Monitoring for subtle signs like petechiae, purpura, gingival oozing, and occult blood in urine or stool, while immediately implementing precautions such as avoiding intramuscular injections, using a soft-bristled toothbrush, and preventing constipation, are not just tasks but critical safety nets.

Analyzing the Other Options

While the other interventions are important components of care for a patient with aplastic anemia, they do not address the most immediate, life-threatening risk.

- Administering prescribed antibiotics: Infection prevention is a high priority due to potential neutropenia in aplastic anemia. However, the question highlights a critically low platelet count, not a low white blood cell count. The risk of fatal hemorrhage from a platelet count of 12,000/mm³ is more acute than the risk of developing a new infection in the immediate moment.

- Encouraging increased fluid intake: This intervention is non-specific and does not target a primary complication of severe thrombocytopenia. While maintaining hydration is generally supportive, it will not prevent a hemorrhagic stroke or internal bleeding.

- Providing a high-protein diet: Nutritional support is valuable for overall bone marrow function and recovery, but it is a long-term, supportive measure. It has no immediate impact on the acute, life-threatening risk of spontaneous bleeding caused by a near-absent platelet count.

Connecting to a Multidimensional Nursing Approach

The case study by Qiu et al. reinforces that managing critical complications from blood dyscrasias requires a comprehensive, vigilant nursing protocol . Their work highlights that intensive monitoring and complication-specific management are associated with favorable outcomes. In your patient's case, the "complication-specific management" for a platelet count of 12,000/mm³ is unequivocally the prevention and early detection of hemorrhage. This involves a systematic assessment that integrates neurological checks (for intracranial bleeding), abdominal assessments (for internal bleeding, as seen in the ovarian cyst case [2]), and meticulous skin and mucosal inspections. The priority is to use your clinical judgment to recognize that a single critical lab value dictates a specific, lifesaving cluster of nursing actions focused on safety and prevention of a sentinel event.References (research sources)

Severe Thrombocytopenia in Aplastic AnemiaPrioritizing Bleeding Precautions
A platelet count below 20,000/mm³ indicates a high risk for spontaneous hemorrhage, which is the immediate life-threatening concern in aplastic anemia.

Key interventions include instituting bleeding precautions: using a soft toothbrush, avoiding rectal medications and IM injections, applying prolonged pressure after venipuncture, and monitoring for petechiae, occult blood, and neurological changes.

CautionWhile infection and anemia are critical concerns in aplastic anemia, the risk of fatal hemorrhage from a platelet count of 12,000/mm³ takes immediate priority. Even minor trauma or physiological events can trigger catastrophic bleeding.

## 핵심 개념

- **Thrombocytopenia** — A condition characterized by abnormally low levels of platelets, increasing the risk of bleeding; a count below 20,000/mm³ poses a risk for spontaneous hemorrhage.
- **Aplastic Anemia** — A rare, serious blood disorder where the bone marrow fails to produce enough new blood cells, leading to pancytopenia.
- **Hemorrhage** — Escape of blood from a ruptured blood vessel; can be life-threatening when spontaneous due to severe thrombocytopenia.
- **Bleeding Precautions** — Nursing interventions to minimize the risk of bleeding, such as using soft toothbrushes, avoiding rectal procedures, and preventing falls.
- **Platelet Count** — A lab test measuring the number of platelets in a blood sample; normal range is typically 150,000 to 400,000/mm³.
