Core Nursing Explanation
Key Concept Analysis: This question tests the priority nursing intervention for a hospitalized child with
varicella (chickenpox). The core principle is
infection control and patient safety. Varicella is caused by the varicella-zoster virus (VZV) and is highly contagious, spreading via
airborne and contact transmission. The presence of lesions in various stages (papules, vesicles, crusts) confirms active infection. In a hospital setting, the primary nursing responsibility is to protect other vulnerable patients and healthcare workers from exposure.
Answer Rationale:
Key Point! The priority is
Implement strict isolation precautions. According to standard and transmission-based precautions, varicella requires
Airborne Precautions (negative pressure room, N95 respirator for susceptible personnel) and
Contact Precautions (gown and gloves) due to the risk of transmission from respiratory droplets and direct contact with fluid from lesions. This intervention addresses the most immediate risk: a hospital-wide outbreak.
Distractor Analysis:
Watch out for confusion! Option ①: Applying topical antibiotics is not a routine or priority intervention. It may be considered only if a
secondary bacterial infection (e.g., from *Staphylococcus aureus* or *Streptococcus pyogenes*) is diagnosed, not prophylactically. The priority is containment, not treatment of a non-existent complication.
Option ③: Administering aspirin is
absolutely contraindicated in children and adolescents with viral illnesses due to the strong association with
Reye's syndrome, a rare but severe condition causing acute encephalopathy and liver failure. Acetaminophen or ibuprofen are appropriate antipyretics.
Option ④: Encouraging scratching is harmful. Scratching can rupture vesicles, increasing the risk of secondary bacterial infection, causing scarring, and further spreading the virus. Nursing interventions should focus on
preventing scratching (e.g., mittens, trimming nails, administering antihistamines for pruritus).
Related Concepts: The nursing process dictates that safety (preventing disease transmission) takes precedence. Other important care aspects include managing pruritus, maintaining hydration, monitoring for complications (e.g., pneumonia, encephalitis), and providing family education on home care and the importance of vaccination.
Concept Summary
| Concept | Key Points |
|---|
| Varicella Transmission | Airborne & Contact. Highly contagious from 1-2 days before rash until all lesions are crusted. |
| Isolation Precautions | Airborne Precautions (negative pressure room, N95) + Contact Precautions (gown & gloves). |
| Complication Prevention | Avoid aspirin (Reye's syndrome risk). Prevent scratching (secondary infection, scarring). |
| Patient Education | Vaccination importance. Home isolation until non-contagious. Comfort measures (cool baths, calamine). |
Side-by-Side Comparison!
| Precaution Type | Diseases/Agents | Key Interventions |
|---|
| Airborne Precautions | Measles, Tuberculosis, Varicella, Disseminated Zoster | Negative pressure room. N95 respirator or higher. Keep door closed. |
| Droplet Precautions | Influenza, Pertussis, Mumps, Rubella | Private room or cohort. Surgical mask within 3 feet (1 meter). |
| Contact Precautions | MRSA, VRE, C. diff, RSV, Varicella (for lesion contact) | Gown & gloves for room entry. Dedicated equipment. |
Anatomy, Physiology & Pharmacology Points
Pathophysiology: VZV infects the respiratory mucosa, replicates, enters the bloodstream (primary viremia), and then causes a widespread vesicular rash upon secondary viremia. Lesions appear in crops and can affect mucous membranes.
Pharmacology Alert:
Key Point! Aspirin/Salicylates are contraindicated in children with viral illnesses due to Reye's syndrome risk. Use acetaminophen or ibuprofen for fever/pain. Antiviral agents (e.g., acyclovir) may be used for immunocompromised or severe cases.

Mnemonic for Varicella Precautions: "
AVoid Contact With Air" – Airborne & Contact precautions for Varicella.
Reye's Syndrome Reminder: "
No ASSpirin for Kids' VirASSes" – Avoid Aspirin/Salicylates for viral illnesses in children.
High-Frequency NCLEX Topics
NCLEX frequently tests: 1) Prioritization of infection control (ABCs – Airway, Breathing,
Contagion), 2) Correct application of transmission-based precautions, 3) Pediatric medication safety (aspirin contraindication), and 4) Identifying appropriate patient education for communicable diseases.
Watch Out for Question Variations!
* Instead of "priority intervention," the question could ask: "
Which precaution sign should be placed on the door?" (Answer: Airborne & Contact).
* It could shift to patient education: "
What should the nurse teach the parents about when the child can return to school?" (Answer: When all lesions are crusted over).
* It could be a safety question: "
The child has a fever of 38.9°C (102°F). Which medication should the nurse prepare to administer?" (Answer: Acetaminophen or Ibuprofen – NOT aspirin).
