Core Nursing Explanation
Key Concept Analysis: This question tests the nurse's knowledge of home care for a child with
Varicella (chickenpox), a highly contagious viral infection caused by the varicella-zoster virus (VZV). The core nursing priority is managing the primary symptom—the intensely itchy vesicular rash—to prevent complications, primarily
secondary bacterial infection from scratching.
Answer Rationale: The correct answer is option 3.
Key Point! The hallmark of varicella is a pruritic (itchy) rash that progresses from macules to papules, vesicles, and crusts. Scratching these lesions can break the skin barrier, introducing bacteria (commonly
Staphylococcus aureus or
Streptococcus pyogenes) and leading to cellulitis, impetigo, or even more serious systemic infections. Keeping fingernails short and clean is a simple, effective, and non-pharmacological intervention that directly addresses this risk and is a cornerstone of patient/family education.
Distractor Analysis:
Watch out for confusion! Option 1: Applying topical antibiotics to
all lesions is not a standard, evidence-based practice. It promotes antibiotic overuse and resistance. Topical antibiotics (e.g., mupirocin) are only indicated if a secondary bacterial infection is already diagnosed.
Watch out for confusion! Option 2:
Key Point! Giving aspirin to a child with a viral illness like varicella is
absolutely contraindicated due to the risk of
Reye's syndrome, a rare but severe condition causing acute encephalopathy and liver failure. For fever and discomfort, acetaminophen or ibuprofen are appropriate antipyretics/analgesics.
Watch out for confusion! Option 4: Returning to school once the fever subsides is incorrect. The standard isolation guideline for varicella is until
all lesions have crusted over, which typically takes 5-7 days. The child remains contagious as long as new vesicles are forming, even without fever.
Related Concepts: Nursing care for varicella also includes symptomatic management: cool baths, calamine lotion for itch relief, antipyretics (avoiding aspirin), maintaining hydration, and airborne/contact isolation precautions. The varicella vaccine is the primary prevention.
Concept Summary
| Concept | Key Points |
|---|
| Disease | Varicella (Chickenpox) - Viral, highly contagious |
| Primary Symptom | Pruritic vesicular rash |
| Major Complication | Secondary bacterial infection from scratching |
| Key Nursing Intervention | Prevent scratching (short/clean nails, mittens, antipruritics) |
| Medication Contraindication | Aspirin (Reye's syndrome risk) |
| Isolation Precautions | Airborne & Contact until all lesions crust |
Side-by-Side Comparison!
| Intervention | Appropriate for Varicella | Inappropriate / Dangerous for Varicella |
|---|
| Fever Management | Acetaminophen, Ibuprofen | Aspirin (Reye's syndrome) |
| Itch Management | Cool baths, Calamine lotion, Antihistamines (e.g., diphenhydramine) | Topical antibiotics on all lesions (unnecessary, promotes resistance) |
| Infection Control | Isolate until all lesions crusted | Return when fever subsides (still contagious) |
Anatomy, Physiology & Pharmacology Points
- Pathophysiology: VZV invades via respiratory tract, replicates, causes viremia, and leads to the characteristic rash. Vesicles contain high concentrations of the virus.
- Pharmacology: Antiviral therapy (e.g., acyclovir) may be used for high-risk patients (immunocompromised, adults) but is not routine for healthy children. Know the Reye's syndrome link between aspirin, viral illness, and mitochondrial damage in the liver/brain.
Memory Tips
- CRUST is a MUST: Child can return when all lesions have Crusted.
- No ASS for VIRUS: Never give ASpirin for a VIRal illnUS.
- Scratch = Bad, Short Nails = Good: The primary nursing goal is to break the itch-scratch-infection cycle.
High-Frequency NCLEX Topics
This is a classic NCLEX question combining
pediatric infectious disease management,
patient/parent education, and
safety (aspirin contraindication). Expect questions on: isolation precautions (airborne/contact), signs of complications (e.g., high fever returning after initial improvement may indicate secondary infection), and vaccine schedules (varicella vaccine at 12-15 months, booster at 4-6 years).
Watch Out for Question Variations!
- Symptom Identification: "The mother reports the child has a fever and small, itchy blisters on the chest. The nurse should suspect..."
- Priority Intervention: "A child with varicella develops a high fever and red, warm, swollen skin around a lesion. What is the nurse's priority action?" (Assess for/secondary bacterial infection).
- Medication Administration: "The mother asks what she can give for fever. Which medication should the nurse recommend?" (Acetaminophen).
- Discharge Teaching: "When teaching parents about home care, which statement by the parent indicates a need for further teaching?" (e.g., "I'll give him baby aspirin for the fever.").
