A 4-year-old child with varicella (chickenpox) is being cared for at home. Which nursing intervention should the nurse prioritize when educating the parents?

Keeping nails short and clean prevents secondary bacterial infection from scratching, which is the priority in home care. Other options are contraindicated (aspirin risks Reye's syndrome) or not priority (topical antibiotics, hot baths).

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for home care of a child with varicella (chickenpox). The core nursing goal is to manage symptoms and prevent complications. The primary complication in varicella is secondary bacterial infection of the skin lesions, often caused by Staphylococcus aureus or Streptococcus pyogenes, which can lead to cellulitis, abscesses, or even invasive disease. The intense pruritus (itching) leads to scratching, which breaks the skin barrier and introduces bacteria.

Answer Rationale: Key Point! The priority intervention is preventing this complication. Keeping the child's fingernails short and clean is a direct, effective, and safe measure to minimize skin damage from scratching and reduce the risk of introducing bacteria. This aligns with the nursing process by addressing the primary risk (Risk for infection) through a preventative, parent-educatable action.

Distractor Analysis:
Watch out for confusion! Option ②: Advising aspirin is a critical error. The use of aspirin (acetylsalicylic acid) in children and adolescents with viral illnesses like varicella or influenza is absolutely contraindicated due to its strong association with Reye's syndrome, a rare but severe condition causing acute encephalopathy and liver failure. For fever and discomfort in varicella, acetaminophen (Tylenol) is recommended.
Option ③: Topical antibiotics are not indicated for all vesicles. They are only used if a secondary bacterial infection is clinically diagnosed (e.g., lesion with purulent drainage, increased redness, warmth). Indiscriminate use can promote antibiotic resistance and is not a priority preventative measure.
Option ④: Hot baths can exacerbate pruritus by causing vasodilation. Lukewarm baths with colloidal oatmeal or baking soda are recommended for soothing itching. Hot water can also damage the fragile vesicles.

Related Concepts: The management of varicella revolves around supportive care: fever management (with non-aspirin antipyretics), itch control (antihistamines like diphenhydramine, cool compresses, calamine lotion), maintaining hydration, and isolation to prevent spread (highly contagious via airborne and contact routes until all lesions are crusted over).

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a pediatric clinic. Mrs. Johnson brings in her 4-year-old son, Liam, who has a fever and a new rash that started on his trunk and is now spreading. You note macules, papules, vesicles, and crusts all present simultaneously—the classic "dew drop on a rose petal" appearance of varicella.

Nursing Intervention Strategy:

1. Assessment: Perform a thorough skin assessment. Document the distribution and stage of lesions. Assess for signs of complications: high fever persisting beyond 4 days, lesions that appear deeply red, warm, swollen, or draining pus (signs of bacterial superinfection), lethargy, difficulty breathing (pneumonia), or severe headache/vomiting (encephalitis).
2. Education & Planning: Develop a home care plan with the parents.
   • Infection Prevention: Emphasize the #1 rule: keep nails short and clean. Consider having the child wear mittens or socks on hands during sleep.
   • Symptom Management: Teach proper antipyretic use (acetaminophen or ibuprofen dosing by weight). Recommend oral antihistamines (e.g., diphenhydramine) for itch. Demonstrate how to apply cool compresses or calamine lotion to itchy spots.
   • Hygiene & Comfort: Instruct on daily lukewarm baths with colloidal oatmeal. Use soft, clean, cotton clothing. Change bed linens frequently.
   • Isolation: The child must stay home from school/daycare until all lesions have crusted over (usually about 5-7 days after rash onset). Avoid contact with pregnant women, newborns, and immunocompromised individuals.
3. Evaluation: Instruct parents on warning signs that require immediate medical re-evaluation (the complications listed in assessment). Provide a follow-up call in 24-48 hours to check on the child's status.

Nursing Procedure & Medication Flow Medication Administration Caution:

Medication	Indication in Varicella	Critical Nursing Precautions
Acetaminophen (Tylenol)	Fever, discomfort	Calculate dose based on child's current weight. Educate on not exceeding maximum daily dose to avoid hepatotoxicity. Do not combine with other acetaminophen-containing products.
Ibuprofen (Advil, Motrin)	Fever, discomfort	Administer with food/milk to minimize GI upset. Avoid in children with dehydration risk due to potential renal effects.
Diphenhydramine (Benadryl)	Pruritus (itching)	Monitor for sedation. Caution parents about drowsiness and avoid activities like biking. Use correct pediatric dose.
ASPIRIN	CONTRANDICATED	NEVER administer or recommend. Reinforce this prohibition clearly and repeatedly to parents. The risk of Reye's syndrome is a life-threatening safety issue.

A Word from Your Senior Nurse "Chickenpox might seem like a common childhood rite of passage, but our nursing vigilance is what prevents it from becoming a hospital admission for a nasty skin infection or worse. Your role in parent education is powerful! When you teach a mom to trim her child's nails, you're not just giving a task—you're empowering her to be the first line of defense against a serious complication. Always connect the 'what' (trim nails) to the 'why' (prevent staph infection). This critical thinking and patient teaching are exactly what the NCLEX tests and what makes an excellent nurse."
