A 4-year-old child is admitted to the pediatric unit with a diagnosis of measles. Which nursing intervention should be the priority?

해설
Measles is highly contagious, requiring immediate airborne isolation to prevent transmission. Other interventions like fever management or hydration are supportive but secondary to infection control.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a child with Measles (Rubeola). Measles is a highly contagious viral infection transmitted via airborne droplets. The core principle in managing any infectious disease, especially one with high transmissibility, is to first prevent transmission to others. This aligns with the public health principle and the nursing responsibility of Standard and Transmission-Based Precautions.

Answer Rationale: Key Point! The immediate priority is Implement strict isolation precautions immediately. Measles requires Airborne Precautions in addition to Contact Precautions (due to respiratory secretions). This means placing the child in a negative pressure room, ensuring healthcare workers and visitors wear an N95 respirator or equivalent, and using strict hand hygiene. This action protects other vulnerable patients, staff, and visitors, which is the highest priority in a healthcare setting.

Distractor Analysis:
Watch out for confusion! Option 1: Administer aspirin for fever reduction - This is contraindicated in children with viral illnesses due to the risk of Reye's syndrome. Acetaminophen or ibuprofen would be appropriate antipyretics, but fever management, while important, is not the immediate safety priority over infection control.
Option 2: Encourage increased fluid intake only - Maintaining hydration is a crucial supportive measure to prevent dehydration from fever and decreased oral intake. However, the word "only" makes this intervention incomplete and not the first action upon admission.
Option 4: Apply cool compresses to the rash - The measles rash is not typically pruritic (itchy) and does not require topical cooling. This is a non-priority, potentially unnecessary intervention. Comfort measures are secondary.

Related Concepts: The NCLEX often tests the "first" or "priority" action using frameworks like Safety and Infection Control (which includes isolation) and Maslow's Hierarchy of Needs (where safety needs, including preventing harm to others, come before comfort needs like fever reduction).

Concept Summary
ConceptKey Points
Measles (Rubeola)Viral, highly contagious. Symptoms: high fever, cough, coryza (runny nose), conjunctivitis, Koplik's spots (white spots on buccal mucosa), followed by a maculopapular rash.
Transmission & IsolationAirborne transmission. Requires Airborne Precautions (negative pressure room, N95 respirator) and Contact Precautions.
Nursing Priorities1. Infection Control (Isolation). 2. Supportive Care (Hydration, fever management with safe antipyretics). 3. Monitoring for Complications (e.g., pneumonia, encephalitis).
ContraindicationAvoid aspirin in children with viral illnesses due to Reye's syndrome risk.

Chickenpox (Varicella)Airborne & ContactAirborne + ContactIsolation; prevent scratching to avoid secondary infection
MumpsDropletDropletIsolation; manage parotitis pain and fever
Fifth Disease (Parvovirus B19)DropletDroplet (mainly for immunosuppressed contacts)Supportive care; educate about "slapped cheek" rash

Anatomy, Physiology & Pharmacology PointsPathophysiology: The measles virus replicates in the respiratory tract, then spreads via the bloodstream (viremia), causing systemic symptoms and the characteristic rash.
Pharmacology: Antipyretics of choice are acetaminophen or ibuprofen. Watch out for confusion! Aspirin is contraindicated. Vitamin A supplementation is recommended in some cases to reduce severity.
Prevention: The MMR (Measles, Mumps, Rubella) vaccine is highly effective.
Memory TipsMnemonic for Measles Symptoms: "3 C's + Rash + K" - Cough, Coryza, Conjunctivitis, Rash, Koplik's spots.
Priority Thinking: "AIRBORNE first!" For diseases spread through the air, isolating the patient is almost always the #1 priority to protect public health.
High-Frequency NCLEX Topics • Infection Control/Transmission-Based Precautions (Airborne vs. Droplet vs. Contact).
• Pediatric medication safety (avoiding aspirin).
• Prioritization: Safety (preventing transmission) over comfort (treating fever).
Watch Out for Question Variations! • Instead of asking for the priority intervention, the question could ask: "Which precaution is required for a child with measles?" (Answer: Airborne and Contact).
• It could present a scenario and ask for the first action: "The nurse receives a child with suspected measles. What should the nurse do first?" (Answer: Place the child in an airborne isolation room).
• It could test contraindicated care: "Which medication should the nurse avoid administering?" (Answer: Aspirin).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse at the pediatric triage desk. A mother brings in her 4-year-old son, Jacob, who has a high fever, a hacking cough, red watery eyes, and a rash starting on his face and spreading downward. He has not been vaccinated due to parental choice. The charge nurse tells you a negative pressure room is being prepared.

Nursing Intervention Strategy:
1. Immediate Action (Priority): Don a surgical mask yourself (upgrade to N95 once available) and provide a mask for the child if tolerated. Immediately escort Jacob and his mother to a private examination room, closing the door. Label the door with Airborne Precautions signage. This minimizes time spent in common areas.
2. Assessment: Once in the room, perform a focused assessment. Check for Koplik's spots (tiny white spots on the inner cheek). Monitor respiratory status for signs of complication like pneumonia (increased work of breathing, crackles).
3. Supportive Care & Education: Educate the mother on the importance of staying in the room. Encourage fluids like popsicles, water, or diluted juice. Administer acetaminophen (15 mg/kg/dose) as ordered for fever. Explain the rash will fade in order of appearance.
4. Reporting: Measles is a reportable disease. Notify the hospital infection control team and public health department as per protocol.

Patient Safety and Precautions:
For Staff/Visitors: Anyone entering the room must wear a fit-tested N95 respirator. Those who are immunocompromised or pregnant should not care for this patient if possible.
For the Patient: Isolation can be distressing for a child. Provide age-appropriate toys and activities that can remain in the room.
Duration of Isolation: Airborne precautions should be maintained for 4 days after the onset of the rash (or for the duration of illness in immunocompromised patients).
Nursing Procedure & Medication Flow Procedure: Initiating Airborne Precautions
1. Recognize the need based on symptoms and diagnosis.
2. Alert the appropriate personnel to prepare a negative pressure room.
3. Place a mask on the patient (if possible) and transport directly to the isolation room.
4. Post appropriate signage on the door.
5. Ensure availability of Personal Protective Equipment (PPE): N95 respirators, gowns, gloves.
6. Educate the patient/family and all staff on the precautions.

Medication: Administering Antipyretics Safely
Drug: Acetaminophen (e.g., Tylenol).
Action: Analgesic and antipyretic (reduces fever).
Pediatric Dose: Calculate based on weight: 10-15 mg/kg/dose every 4-6 hours as needed. Double-check calculations.
Key Safety Point: Verify the formulation (infant drops vs. children's suspension) and concentration to avoid dosing errors. Never use aspirin.
A Word from Your Senior Nurse "In the real world, a case of measles in a hospital is a 'code red' for infection control. We move fast to contain it. Remember, your role isn't just to care for one sick child; it's to protect every other baby on the unit, every pregnant visitor, and every immunocompromised patient from a potentially severe illness. That's the weight of our responsibility. When you see 'airborne,' think 'urgent isolation.' That instinct to protect the many over the comfort of the one is at the heart of public health nursing and will guide you to the right answer on your boards and at the bedside."
