A 7-year-old child with sickle cell anemia is admitted to the pediatric unit with severe pain in the legs and arms. Which nursing intervention should be the priority?

Oxygen saturation of 89% indicates severe hypoxemia, which can worsen sickling and tissue damage, making oxygen therapy the priority to break the cycle. Pain management, hydration, and warmth are important but secondary to addressing hypoxemia.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a child experiencing a Vaso-occlusive crisis (VOC), also known as a pain crisis, in Sickle cell disease (SCD). The core pathophysiology is the sickling of red blood cells (RBCs) under conditions of hypoxia, acidosis, dehydration, and infection, leading to vessel occlusion, ischemia, severe pain, and potential organ damage. The scenario provides a critical clue: the child's oxygen saturation is 89%. This Key Point! indicates significant hypoxemia, which is a primary driver and exacerbating factor of the sickling process.

Answer Rationale: The priority is Initiate oxygen therapy. In SCD, hypoxia is both a cause and a consequence of the VOC. Low oxygen saturation (Normal for a child: 95-100%) promotes further sickling, which worsens occlusion and tissue ischemia, creating a vicious cycle. Administering supplemental oxygen is a direct, life-sustaining intervention aimed at the root cause. It increases arterial oxygen levels, helps reverse sickling, improves tissue perfusion, and prevents further complications like acute chest syndrome (a leading cause of death in SCD). According to the ABC (Airway, Breathing, Circulation) framework, addressing oxygenation (Breathing) takes precedence over comfort measures.

Distractor Analysis:
① Watch out for confusion! While administering analgesics is crucial and should be done promptly, it addresses the symptom (pain) rather than the underlying physiological crisis (hypoxia and ongoing sickling). Pain management is a high-priority comfort measure but is secondary to stabilizing a life-threatening physiological parameter.
② Encouraging fluid intake is vital to treat dehydration, which is a known precipitant of VOC. However, oral encouragement is a slower process. In the face of active hypoxemia, correcting oxygenation is more immediate. IV hydration is often initiated concurrently.
③ Applying warm compresses can help with vasodilation and pain relief. However, it is a comfort measure and does not address the core issue of systemic hypoxia. Applying cold is contraindicated as it causes vasoconstriction and can worsen sickling.

Related Concepts: The management of a sickle cell crisis is multifaceted. After stabilizing oxygenation (Airway/Breathing), the next priorities typically include aggressive IV hydration and Opioid analgesia (often via patient-controlled analgesia (PCA) pumps). Monitoring for signs of Acute chest syndrome (fever, cough, chest pain, worsening hypoxia) and Stroke is critical. The elevated WBC (15,000/mm³) and history of URI suggest infection is a trigger, so monitoring for sepsis is also important.

Concept Summary

Concept	Key Points
Sickle Cell Disease (SCD)	Genetic disorder causing abnormal hemoglobin (HbS). RBCs sickle under stress, leading to vaso-occlusion.
Vaso-occlusive Crisis (VOC)	Most common type of crisis. Presents with severe pain in bones/joints/extremities (dactylitis in young children).
Precipitating Factors	Dehydration, infection, hypoxia, cold exposure, emotional stress.
Priority Intervention	Address ABCs. Hypoxemia (O2 sat 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are the nurse admitting 7-year-old "Leo" to the pediatric unit. He is curled in bed, crying and guarding his legs. His parents are anxious. His vital signs are: Temp 38.2°C, HR 132, RR 28, BP 98/60, SpO2 89% on room air. His skin is pale, and capillary refill in his toes is 4 seconds. Nursing Intervention Strategy: Immediate Action (Priority): Apply supplemental oxygen via nasal cannula or face mask as ordered to achieve SpO2 >95%. Reassess SpO2 and respiratory effort frequently. Comprehensive Assessment: Perform a focused pain assessment using an age-appropriate scale (e.g., FACES scale). Assess for signs of acute chest syndrome (auscultate lungs, note cough). Start IV access for fluids and medications. Collaborative Care: Administer prescribed IV fluids (often 1.5x maintenance) to correct dehydration. Administer opioid analgesics on a scheduled basis, not just PRN, to maintain therapeutic levels and break the pain cycle. Administer antipyretics for fever and antibiotics if infection is suspected. Comfort & Monitoring: Apply warm (not hot) compresses to painful areas. Position for comfort. Monitor strict I&O. Monitor for signs of opioid side effects (respiratory depression, constipation) and crisis complications (worsening pain, neurological changes, respiratory distress). Patient Safety and Precautions: Never apply cold to painful areas—it causes vasoconstriction and worsens sickling. Be vigilant for acute chest syndrome: any new cough, fever, chest pain, or drop in SpO2 must be reported immediately. When giving opioids, monitor respiratory rate closely, especially with concurrent oxygen therapy, as hypoxia is a primary respiratory drive for these patients. Nursing Procedure & Medication Flow Oxygen Therapy Initiation: 1. Verify order. 2. Explain procedure to child/parents. 3. Choose appropriate delivery device (nasal cannula for low flow, simple mask for higher concentration). 4. Set flow rate as ordered (e.g., 2-4 L/min via cannula). 5. Ensure proper fit and patient comfort. 6. Document SpO2 before and after, device, and flow rate. Opioid Administration (IV): 1. Double-check the "Five Rights". 2. For PCA, ensure the child/parent understands the button is for the patient only. 3. Administer a loading dose if ordered. 4. Monitor for effectiveness (pain score reduction) and adverse effects (sedation, respiratory depression, nausea). 5. Have naloxone available per protocol. A Word from Your Senior Nurse "Seeing a child in a sickle cell pain crisis is heartbreaking. Your instinct might be to rush and comfort them—and you should, with a calm presence and gentle touch. But your first clinical action must be to look at the monitor and address the numbers that are keeping them in that cycle of pain. That SpO2 of 89% is a red alarm. By getting oxygen on quickly, you're not just following an order; you're giving their red blood cells a chance to unsickle, you're giving their tissues oxygen, and you're starting to treat the cause of their agony. Remember, in pediatrics, you're caring for the whole family. Explain what you're doing and why to the scared parents. Your calm, knowledgeable response is their first sign of hope." 핵심 개념 Sickle Cell Disease — A group of inherited red blood cell disorders where hemoglobin S (HbS) causes red blood cells to become rigid and sickle-shaped, leading to chronic anemia, pain, and organ damage. Vaso-occlusive Crisis — The most common acute complication of SCD, characterized by blockage of blood flow by sickled cells, resulting in severe ischemic pain, often in the bones, chest, abdomen, or joints. Acute Chest Syndrome — A life-threatening complication of SCD characterized by fever, respiratory symptoms, chest pain, and new pulmonary infiltrates. It is a leading cause of death and often requires urgent transfusion. Hypoxemia — A below-normal level of oxygen in the arterial blood (PaO2 < 80 mmHg or SpO2 < 95%). In SCD, it is a major precipitant and consequence of sickling. Hydroxyurea — A medication used in SCD to reduce the frequency of pain crises and acute chest syndrome by increasing the production of fetal hemoglobin (HbF), which inhibits the polymerization of HbS. 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
