A 7-year-old child with hemophilia A is brought to the emergency department after falling from a bicycle and hitting his head. The child is alert and oriented, with no visible external injuries. Which nursing intervention should be the priority?

Priority nursing intervention for a child with hemophilia A following head trauma
해설
Factor VIII replacement therapy is the priority intervention for a child with hemophilia A who has sustained head trauma, even without visible external injuries.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the critical nursing priority for a patient with Hemophilia A, a congenital bleeding disorder caused by a deficiency in clotting Factor VIII. The core principle is that any trauma, especially to a critical area like the head, poses a significant risk for intracranial hemorrhage, which can be life-threatening. The absence of visible injury is dangerously misleading; internal bleeding can occur without external signs. The priority is to prevent or stop bleeding by replacing the missing clotting factor.

Answer Rationale: Key Point! The correct answer is Prepare for immediate factor VIII replacement therapy. In hemophilia, the fundamental problem is a missing component of the clotting cascade. For a head injury, the risk is not just pain or swelling, but a potentially fatal bleed inside the skull. The single most effective intervention to prevent this complication is to rapidly correct the underlying coagulopathy by administering the deficient factor. This action directly addresses the life-threatening pathophysiology.

Distractor Analysis:
Watch out for confusion! While Obtaining vital signs and performing a complete physical assessment (Option 2) is a crucial and immediate nursing action, it is an assessment step, not the definitive intervention. In a potential emergency, assessment informs the need for intervention, but the lifesaving treatment itself takes precedence once the risk is identified (a hemophiliac with head trauma).
Watch out for confusion! Applying ice packs (Option 1) is a general first-aid measure for minor trauma to reduce swelling. It does nothing to correct the underlying clotting deficiency and would waste critical time.
Watch out for confusion! Administering analgesics (Option 3), especially non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, is often contraindicated in bleeding disorders as they can impair platelet function and worsen bleeding. Pain management is important but secondary to securing the airway, breathing, circulation, and treating the cause of potential deterioration.

Related Concepts: The nursing process dictates that for a patient with a known high-risk condition (hemophilia) and a high-risk event (head trauma), the plan and implementation must target the specific, imminent threat. This aligns with Evidence-Based Nursing (EBN) guidelines for hemophilia management, which emphasize prompt factor replacement for trauma. Understanding the difference between Hemophilia A (Factor VIII deficiency) and Hemophilia B (Factor IX deficiency, Christmas disease) is also key for correct treatment. Concept Summary
ConceptDescriptionNursing Implication
Hemophilia AX-linked recessive disorder causing Factor VIII deficiency.Bleeding into joints (hemarthrosis), muscles, and internally after trauma.
Factor Replacement TherapyIV infusion of concentrated clotting factor (Factor VIII for Hemophilia A).Primary treatment for bleeding episodes and prophylaxis. Must be administered promptly.
Head Trauma in Bleeding DisordersA medical emergency. Risk of intracranial hemorrhage (ICH) without external signs.Priority is factor replacement, NOT wait-and-see. Monitor for neuro changes (headache, vomiting, lethargy).
Nursing Priority (ABCs)Airway, Breathing, Circulation. In this case, preventing circulatory compromise from internal bleeding is key.Interventions that directly support ABCs (like replacing blood/clotting factors) take top priority.
Side-by-Side Comparison!
ScenarioPriority Nursing InterventionRationale
Child with Hemophilia & Head TraumaPrepare for/Administer Factor VIIILife-threatening risk of intracranial bleed. Treat the underlying cause.
Child without Bleeding Disorder & Head Trauma (alert, no injury)Neurological assessment & monitoring (Vital signs, neuro checks)Rule out concussion or internal injury. Observation is key.
Child with Hemophilia & Knee Swelling (Hemarthrosis)Factor VIII replacement, RICE protocol (Rest, Ice, Compression, Elevation)Treat bleeding into joint to prevent pain and long-term damage.
Anatomy, Physiology & Pharmacology Points Pathophysiology: The clotting cascade is a series of steps. Factor VIII is a crucial cofactor in the intrinsic pathway. Its deficiency severely impairs the formation of a stable fibrin clot.
Pharmacology: Factor VIII concentrate is administered intravenously. Dosage is based on units/kg. Nurses must monitor for adverse reactions, including allergic responses or the development of inhibitors (antibodies against Factor VIII).
Neurological Anatomy: The rigid skull has no space for expansion. Any bleeding (hematoma) increases intracranial pressure (ICP), which can lead to brain herniation and death. Memory Tips Acronym: HEAD = Hemophilia Emergency: Administer Factor VIII for any Head trauma.
Association: Think of hemophilia as a car without brakes. Trauma is pressing the gas. Applying ice (Option 1) is like cleaning the windshield—it doesn't stop the car. Factor VIII is installing the brakes.
Rule of Thumb: For a bleeding disorder + trauma to a closed space (head, abdomen, chest) = Key Point! Assume internal bleeding until proven otherwise. Treat first, assess concurrently. High-Frequency NCLEX Topics NCLEX loves to test priority-setting and client-specific interventions. Hemophilia is a classic disease for testing if you understand that a patient's chronic condition changes the standard response to a common injury. You must move beyond generic first aid to disease-specific, life-saving treatment. Watch Out for Question Variations! * Shift from Symptom to Intervention: "The child with hemophilia A develops a severe headache and vomiting 2 hours after a minor head bump. What should the nurse do first?" (Answer: Prepare for Factor VIII and notify the provider immediately – signs of increased ICP). * Shift to Medication Knowledge: "Which analgesic is contraindicated for pain management in this child?" (Answer: Ibuprofen or aspirin – they are antiplatelet agents). * Shift to Patient Education: "What is the priority teaching for the parents upon discharge?" (Answer: Seek immediate medical attention for any head injury, no matter how minor).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the Pediatric ED. A frantic mother brings in her 7-year-old son, who has severe hemophilia A. He fell off his bike about 30 minutes ago, hit his forehead on the pavement, but "seems fine now." He is alert, talking, and has a small abrasion on his forehead with minimal swelling.

Nursing Intervention Strategy: 1. Immediate Action (Priority): While quickly guiding them to a treatment room, alert the charge nurse and physician. State clearly: "Pediatric patient with known hemophilia A, s/p head trauma. Will need Factor VIII stat." Begin gathering supplies for IV access and factor administration. 2. Simultaneous Assessment: As you prepare, efficiently obtain vital signs, focusing on blood pressure (for hypotension) and heart rate (for tachycardia). Perform a rapid neurological assessment using a pediatric Glasgow Coma Scale (GCS). Ask about headache, nausea, visual changes. 3. Implementation: Once the order is received, administer Factor VIII concentrate via IV push or infusion per protocol. Document the lot number and time precisely. 4. Ongoing Monitoring & Evaluation: After administration, the child must be admitted for at least 24 hours of neurological observation, even if asymptomatic. Continue neuro checks every 1-2 hours. Evaluate for effectiveness of therapy (no progression of symptoms) and for any adverse reaction to the factor product.

Patient Safety and Precautions: * Contraindication: Do not give intramuscular injections (IM), including vaccinations, without factor coverage and provider consultation, as they can cause hematomas. * Medication Caution: Avoid all medications that affect platelets or coagulation (aspirin, NSAIDs). Use acetaminophen for pain/fever if needed. * Key Monitoring: Watch for signs of intracranial hemorrhage (ICH): worsening headache, persistent vomiting, lethargy, unequal pupils, seizures, or changes in behavior/consciousness. Nursing Procedure & Medication Flow Procedure: Administering Factor VIII Concentrate 1. Verify order (dose in units/kg). Perform two-patient identifier check. 2. Obtain factor vial from pharmacy or specialized fridge. Check expiration date and integrity. 3. Reconstitute with provided diluent gently (do not shake vigorously to avoid denaturing protein). 4. Administer via IV push slowly or via IV infusion pump over 5-15 minutes as per protocol. 5. Monitor vital signs before, during, and after infusion for reactions (fever, chills, rash, tachycardia). 6. Document: Time started/ended, dose (units), lot number, site, patient tolerance. A Word from Your Senior Nurse "Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In this scenario, your knowledge of hemophilia turns you from a passive order-taker into an active advocate. You know that 'looks fine' can be a trap. By anticipating the need for Factor VIII and initiating those preparations immediately, you save crucial minutes. In clinical practice and on the NCLEX, always ask yourself: 'What is the unique, worst-case scenario for THIS specific patient?' That critical thinking will guide you to the right priority every time."
