## 문제

A nurse is assessing a 35-year-old Hispanic client with sickle cell anemia who presents to the emergency department. Which assessment finding would be the highest priority for immediate intervention?

The client reports severe chest pain, shortness of breath, and has been experiencing fatigue for the past 2 days.

## 보기

1. Hemoglobin level of 7.2 g/dL
2. Jaundice of the sclera and skin
3. Reports of severe bone pain in extremities
4. Oxygen saturation of 88% on room air **✔ 정답**

**정답: 4**

## 해설

Oxygen saturation of 88% indicates severe hypoxemia and potential acute chest syndrome, which is a life-threatening complication requiring immediate intervention.

This question assesses the ability to distinguish the highest-priority emergency among various symptoms that can occur in patients with sickle cell anemia. The correct answer is option 4: "Oxygen saturation of 88% on room air."

An oxygen saturation of 88% indicates severe hypoxemia and suggests the development of acute chest syndrome (ACS), a life-threatening complication of sickle cell disease. Acute chest syndrome is characterized by chest pain, dyspnea, fever, and pulmonary infiltrates on chest X-ray, and can rapidly progress to respiratory failure and death if untreated.

Pathophysiologically, sickling of red blood cells in the pulmonary vasculature leads to vascular occlusion, tissue hypoxia, and inflammation. This creates a vicious cycle of further sickling and worsening hypoxemia. Early recognition and treatment are crucial to prevent progression to acute respiratory distress syndrome (ARDS) and multi-organ failure.

Immediate interventions include oxygen therapy, pain management, hydration, and exchange transfusion if necessary. While other findings are also typical symptoms of sickle cell anemia, they do not pose as immediate a life threat as decreased oxygen saturation.

Clinical Priority Setting in Sickle Cell Anemia

When prioritizing care for a client with sickle cell anemia (SCA), the nurse must apply the ABC (Airway, Breathing, Circulation) framework. This client's report of severe chest pain, shortness of breath, and fatigue strongly suggests a developing acute chest syndrome (ACS), a life-threatening complication of SCA. ACS is a form of acute lung injury and a leading cause of death in adults with SCD, driven by vaso-occlusion, infection, or fat embolism [3]. In this context, an oxygen saturation of 88% on room air indicates significant hypoxemia, directly threatening airway and breathing. This finding demands the highest priority for immediate intervention, such as supplemental oxygen administration, to prevent rapid clinical deterioration.

The other assessment findings are significant manifestations of SCA but do not represent an immediate threat to the airway or breathing in the same way. A hemoglobin level of 7.2 g/dL reflects the client's baseline chronic anemia due to hemolysis; while it requires monitoring, it is a chronic compensatory state and not an acute airway or breathing emergency. Jaundice is a common physical finding resulting from chronic hemolysis and hyperbilirubinemia and, on its own, does not require emergent intervention. Severe bone pain is the hallmark of a vaso-occlusive episode (VOE) and requires prompt analgesic management, but it does not take priority over a critical drop in oxygenation that signals potential respiratory failure. The nurse's role in the hospital setting is pivotal in recognizing these subtle but critical changes, as early detection and holistic management of complications like ACS directly influence patient outcomes [4].References (research sources)

## 임상 시나리오

Acute Chest Syndrome (ACS) in Sickle Cell DiseaseRecognizing and Responding to a Life-Threatening Emergency
A new pulmonary infiltrate on chest imaging combined with fever, chest pain, tachypnea, or hypoxemia defines ACS, a leading cause of death in adults with SCD. An oxygen saturation below 92% on room air is a critical threshold requiring immediate intervention.

Prioritize the ABCs by administering supplemental oxygen to maintain saturations above 95%, obtaining a chest X-ray, and notifying the provider for urgent broad-spectrum antibiotics and analgesia. Pain from a concurrent vaso-occlusive episode should be treated aggressively but does not supersede airway and breathing management.

CautionDo not mistake a patient's baseline anemia or jaundice for the cause of acute deterioration. A sudden drop in oxygen saturation in a patient with SCD and chest pain is ACS until proven otherwise and can progress rapidly to respiratory failure.

## 핵심 개념

- **Acute Chest Syndrome (ACS)** — A life-threatening complication of sickle cell disease involving pulmonary infiltrates, hypoxemia, and respiratory distress, often triggered by vaso-occlusion, infection, or fat embolism.
- **ABC Priority Framework** — A triage and assessment model where Airway, Breathing, and Circulation issues take precedence over other problems to prevent immediate mortality.
- **Vaso-occlusive Episode (VOE)** — An acute painful crisis in sickle cell disease caused by sickled red blood cells obstructing microvasculature, leading to tissue ischemia and severe pain.
