A 7-year-old child with hemophilia A is admitted to the pediatric unit following a fall that resulted in a suspected intracranial hemorrhage. Which nursing intervention should be the PRIORITY?

The child presents with altered level of consciousness, vomiting, and bradycardia.
해설
Factor VIII concentrate administration is the priority intervention for a child with hemophilia A experiencing intracranial hemorrhage, as it directly addresses the underlying clotting deficiency that is causing the life-threatening bleeding.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a life-threatening complication in a patient with a specific bleeding disorder. The core theme is Emergency management of hemorrhage in Hemophilia A. Hemophilia A is a genetic disorder characterized by a deficiency of Factor VIII, a crucial protein in the intrinsic pathway of the coagulation cascade. An intracranial hemorrhage (ICH) is a medical emergency due to the risk of increased intracranial pressure (ICP), brain herniation, and death. The priority is to stop the bleeding at its source by correcting the underlying clotting factor deficiency.

Answer Rationale: Key Point! The cardinal signs of increased ICP are present: altered level of consciousness, vomiting, and bradycardia (a late sign indicating severe pressure on the brainstem). In a patient with hemophilia, the immediate cause of this ICH is the inability to form a stable clot. Therefore, the single most effective and priority intervention is to replace the missing clotting factor. Preparing for and administering Factor VIII concentrate is a direct, life-saving measure that addresses the pathophysiology. This intervention takes precedence over all supportive or symptomatic care.

Distractor Analysis:
Watch out for confusion! Option ①, administering analgesics, is important for comfort but is not the priority. More critically, some analgesics like aspirin or NSAIDs (Nonsteroidal Anti-inflammatory Drugs) are contraindicated in bleeding disorders as they can further impair platelet function. Pain management should not delay definitive treatment.
Option ③, applying ice packs, is a supportive measure for superficial injuries to promote vasoconstriction and reduce swelling. It is ineffective for deep, internal bleeding like an ICH and would waste critical time.
Option ④, positioning in Trendelenburg (head down, feet elevated), is absolutely contraindicated in suspected ICH. This position would increase intracranial pressure by promoting venous congestion in the head and brain, potentially worsening the hemorrhage and herniation. The correct position for a suspected ICH is with the head of the bed elevated to promote venous drainage.

Related Concepts: The nursing process dictates that life-threatening conditions (Airway, Breathing, Circulation, and in this case, uncontrolled bleeding) are addressed first (ABCs). This scenario integrates knowledge of hematology, neurology, and emergency nursing. Understanding the difference between hemophilia A (Factor VIII deficiency) and hemophilia B (Factor IX deficiency) is also crucial for correct treatment.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in a pediatric emergency department. A 7-year-old boy with a known history of severe Hemophilia A is brought in by his anxious parents. He fell off his bike about 2 hours ago, hit his head on the pavement, and now is increasingly drowsy, has vomited twice, and his heart rate is slowing down.

Nursing Intervention Strategy: 1. Immediate Assessment & Notification: Perform a rapid neurological assessment using the Pediatric Glasgow Coma Scale (GCS). Check vital signs, noting bradycardia. Immediately notify the physician and hematology team. Do not wait for a CT scan confirmation to initiate the clotting factor protocol. 2. Priority Action - Factor Administration: While the physician is being notified, prepare the recombinant Factor VIII concentrate as per the hospital's hemophilia protocol. Verify the dose based on the child's weight and the severity of the bleed (for ICH, a high dose is typically required to achieve 100% factor level). Administer it via IV push or infusion as quickly as possible once it is prepared and verified. 3. Concurrent Supportive Care: * Positioning: Elevate the head of the bed to 30 degrees with the head in midline alignment to facilitate cerebral venous drainage. * Monitoring: Continuously monitor neurological status (GCS, pupil checks), vital signs, and oxygen saturation. Prepare for possible intubation if the level of consciousness deteriorates further. * Environment: Keep the environment calm, quiet, and dimly lit to minimize stimuli that could increase ICP. * IV Access: Ensure patent IV access for factor administration and emergency medications.

Patient Safety and Precautions: * Medication Caution: Avoid all medications that affect coagulation or platelet function (e.g., aspirin, ibuprofen). Use acetaminophen for fever or pain, if necessary, with caution. * Procedure Caution: Avoid unnecessary venipunctures, intramuscular (IM) injections, or rectal temperatures. If essential, apply prolonged pressure. * Family Support & Education: Provide clear, calm explanations to the terrified parents. Reinforce the importance of immediate medical attention for any head injury in the future.

Nursing Procedure & Medication Flow Factor VIII Concentrate Administration: 1. Verify: Confirm the order, patient identity, and the specific factor product (recombinant is standard to avoid viral transmission). 2. Calculate: Dose is calculated in international units (IU). Formula often used: Dose (IU) = Desired % rise × Weight (kg) × 0.5. For a major bleed like ICH, the goal is often to raise factor level to 100%. 3. Reconstitute: Use the provided sterile diluent. Gently swirl or roll the vial; do not shake vigorously to avoid denaturing the protein. 4. Administer: Administer via IV push over a few minutes or as a short infusion as per protocol. Monitor for adverse reactions like allergic symptoms or fever. 5. Document: Precisely document the lot number, expiration date, dose, time, and route. Monitor and document the clinical response.

핵심 개념

  • Hemophilia A — An X-linked recessive genetic disorder resulting in a deficiency of clotting Factor VIII, leading to prolonged bleeding primarily into joints and soft tissues.
  • Intracranial Hemorrhage — Bleeding within the skull, a life-threatening emergency that can cause increased intracranial pressure, brain damage, and herniation.
  • Factor VIII Concentrate — The specific clotting factor replacement therapy for Hemophilia A. It is administered intravenously to stop or prevent bleeding episodes.
  • Cushing's Triad — A classic set of vital sign changes indicating increased intracranial pressure: Hypertension (with widening pulse pressure), Bradycardia, and Irregular respirations.
  • Recombinant Factor — Clotting factors produced using DNA technology, which are the standard of care as they carry no risk of transmission of blood-borne viruses like HIV or Hepatitis. Concept Summary
