A 4-year-old preschooler is diagnosed with scabies. Which nursing intervention should be the priority when caring for this child?

Priority intervention is strict isolation and simultaneous treatment of all family members to prevent transmission, as scabies is highly contagious. Other options address symptoms but not the primary infection control need.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for scabies, a highly contagious parasitic skin infestation caused by the Sarcoptes scabiei mite. The core nursing principle here is infection control and transmission prevention. While symptom management is important, the primary public health and clinical goal is to stop the cycle of infestation and reinfestation.

Answer Rationale: Key Point! The correct answer is ③ Implement strict isolation precautions and treat all family members simultaneously. Scabies spreads through prolonged skin-to-skin contact and, less commonly, through infested bedding or clothing. A single infected person can quickly spread the mites to close household contacts. Therefore, the priority intervention is to break the chain of transmission. This involves two critical actions: 1) Contact isolation (using gloves and gowns for direct care) to protect healthcare workers and other patients, and 2) Concurrent treatment of all close contacts, even if asymptomatic, to eradicate the mites from the entire environment and prevent "ping-pong" reinfection.

Distractor Analysis:
Watch out for confusion! Option ① (Apply topical antibiotics) is incorrect because scabies is a parasitic infestation, not a primary bacterial infection. Antibiotics are only indicated if a secondary bacterial infection (e.g., impetigo) develops from scratching. The primary treatment is a scabicide (e.g., permethrin cream).
Option ② (Administer oral antihistamines) addresses the symptom of pruritus (itching), which is a significant problem but is not the priority. The itching is an allergic reaction to the mites and their waste. While antihistamines like diphenhydramine may be part of the care plan to provide comfort and prevent excoriation, they do not treat the underlying cause or prevent spread.
Option ④ (Provide cool compresses) is a supportive, comfort measure for inflammation and itching. Like antihistamines, it is a symptomatic intervention and does not address the core issues of infection control and eradication of the parasite.

Related Concepts: The principle of treating all close contacts simultaneously applies to other contagious conditions like pediculosis (lice) and certain fungal infections (e.g., tinea capitis). In pediatrics, always consider the family unit when managing communicable diseases.
Concept Summary
Disease: Scabies (Sarcoptes scabiei mite infestation).
Transmission: Prolonged skin-to-skin contact; fomites (clothing, bedding).
Key Symptom: Intense nocturnal pruritus; characteristic burrows (linear tracks), papules, vesicles.
Primary Treatment: Topical scabicide (e.g., Permethrin 5% cream).
Priority Nursing Action: Infection Control & Contact Treatment.
Side-by-Side Comparison!

Intervention	Purpose/Rationale	Priority Level
Treat all family members	Eradicates reservoir of mites, prevents reinfection cycle.	HIGHEST (Priority)
Administer oral antihistamines	Manages symptom (pruritus), prevents skin breakdown from scratching.	Intermediate (Comfort/Safety)
Apply topical antibiotics	Treats secondary bacterial infection (if present).	Conditional (Only if infection develops)
Provide cool compresses	Provides temporary symptomatic relief for inflammation/itching.	Low (Supportive Care)

Anatomy, Physiology & Pharmacology Points
Pathophysiology: The female mite burrows into the stratum corneum, lays eggs, and causes a hypersensitivity reaction (Type IV delayed hypersensitivity), leading to intense itching.
Pharmacology (Scabicides): Permethrin 5% cream is a neurotoxin to mites. It is applied from the neck down, left on for 8-14 hours, then washed off. A second application 1 week later is often recommended. Lindane is an older, less preferred agent due to neurotoxicity risk.
Environmental Decontamination: All clothing, bedding, and towels used by the infected person in the 3 days prior to treatment should be washed in hot water and dried on high heat or sealed in a plastic bag for at least 72 hours (mites cannot survive off human skin for more than 2-3 days).
Memory Tips
Mnemonic for Scabies Priority: "STOP IT"
Simultaneous treatment of contacts.
Topical scabicide application.
Occupational/contact isolation.
Prevent reinfection via environment.
Itching management (antihistamines) is secondary.
Teach family about treatment and cleaning.
High-Frequency NCLEX Topics The NCLEX frequently tests on priority-setting for communicable diseases. For any highly contagious condition (scabies, lice, measles, varicella, C. diff), the priority is almost always infection control and transmission prevention before moving to comfort or specific treatment for the individual. Remember the safety principle: protect others first.
Watch Out for Question Variations!

• Instead of asking for the priority intervention, a question might ask: "The nurse is providing discharge teaching for a child with scabies. Which statement by the parent indicates a need for further teaching?" The incorrect statement would be one that indicates treating only the symptomatic child.
• A question could present a scenario with multiple symptoms and ask for the priority assessment finding. For scabies, the priority finding prompting immediate action would be signs of a secondary infection (fever, purulent drainage) or identification of other household members with symptoms.

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a pediatric clinic. A mother brings in her 4-year-old son, complaining that he has been "itching like crazy" for the past week, especially at night. On assessment, you note excoriated papules and linear burrows between his fingers and on his wrists. You suspect scabies.

Nursing Intervention Strategy:

1. Assessment & Confirmation: Perform a thorough skin assessment. The provider may perform a mineral oil scraping to visualize mites, eggs, or feces under a microscope to confirm diagnosis.
2. Priority Action - Infection Control & Education:
   • Immediately place the child in a private room if in a hospital setting. Use Contact Precautions (gloves and gown) for any direct care.
   • Educate the family emphatically: "Everyone living in the household, and any other close contacts (like frequent sleepover buddies), must be treated at the same time, even if they don't itch." This is the most critical teaching point.
   • Provide written instructions for the prescribed scabicide (usually permethrin).
3. Symptom Management & Safety: Explain that itching may persist for 2-4 weeks after successful treatment due to the ongoing allergic response. Recommend oral antihistamines at bedtime and keep the child's fingernails short and clean to prevent excoriation and secondary infection.
4. Environmental Decontamination: Instruct the family on cleaning all linens, clothing, and stuffed animals. Items that cannot be washed can be sealed in plastic bags for 4 days.

Patient Safety and Precautions:

• Medication Application: Teach to apply the cream to cool, dry skin from the neck down, covering the entire body (including under nails, between toes, and genital area). Avoid eyes and mucous membranes. For infants and young children, application may include the scalp and face.
• Contraindications/Precautions: Lindane is contraindicated in premature infants, young children, and patients with seizure disorders. Permethrin is the first-line agent.
• Monitoring: Assess for treatment failure (persistent symptoms after 2-4 weeks), which may indicate incorrect application, reinfestation, or drug resistance.

Nursing Procedure & Medication Flow Procedure: Administering Topical Scabicide (Permethrin 5% Cream)

1. Verify provider order and patient identity.
2. Don gloves.
3. Instruct family to bathe and dry the child.
4. Apply a thin layer of cream to all skin surfaces from the neck down. Pay special attention to creases (finger webs, wrists, axillae, waist, buttocks).
5. Leave the cream on for 8-14 hours (usually overnight).
6. After the recommended time, bathe the child to remove the cream.
7. Put on clean clothing and use clean bedding.
8. Repeat the entire process in 7 days to kill any newly hatched mites.

A Word from Your Senior Nurse "Scabies cases can be stressful for families—the itching is miserable, and the idea of 'bugs' is upsetting. Your calm, knowledgeable demeanor is key. Remember, your most important job is to be a public health educator in that moment. One untreated family member means the whole cycle starts over. In clinical practice, I've seen entire families suffer for months because this simple step was missed. On the NCLEX, they are testing your ability to see the bigger picture: nursing isn't just about the patient in front of you; it's about protecting the community. Always think: 'How do I stop this from spreading?' That's the mark of a safe and effective nurse."
