A 4-year-old child presents to the pediatric clinic with honey-crusted lesions on the face and arms. The lesions are superficial and appear to be spreading. The child has been scratching the affected areas, and some lesions show signs of secondary infection. The healthcare provider diagnoses impetigo and prescribes topical antibiotic therapy. Which nursing intervention should be prioritized in the care plan?

A 6-year-old child presents to the pediatric clinic with honey-crusted lesions on the face and arms. The lesions are superficial and appear to be spreading. The child has been scratching the affected areas, and some lesions show signs of secondary infection. The healthcare provider diagnoses impetigo and prescribes topical antibiotic therapy.

1. Apply warm compresses to the affected areas three times daily
2. Encourage the child to wash hands frequently with antibacterial soap
3. Teach proper hand hygiene and prevent scratching of lesions **✔ 정답**
4. Administer oral antibiotics as prescribed by the healthcare provider

**정답: 3**

## 해설

Teaching hand hygiene and preventing scratching are prioritized as they directly address transmission and healing in impetigo. Other options like warm compresses, handwashing with antibacterial soap, and oral antibiotics are important but secondary to these core interventions.

Understanding the Priority Nursing Intervention for Impetigo

This question focuses on the management of a child with impetigo, a highly contagious superficial bacterial skin infection. The hallmark presentation includes honey-crusted lesions, often on the face and extremities, which spread easily through autoinoculation, particularly when a child scratches the affected areas. While the healthcare provider has prescribed topical antibiotic therapy, the nurse's priority is to halt the chain of transmission and prevent the development of new lesions or secondary infection.

The correct answer is to teach proper hand hygiene and prevent scratching of lesions. The pathophysiological basis for this intervention lies in the mechanism of impetigo spread. The bacteria, most commonly Staphylococcus aureus or Group A Streptococcus (GAS), colonize the superficial epidermis. When a child scratches a lesion, the bacteria are transferred under the fingernails and to the fingers, a process known as autoinoculation. Subsequent touching of other body parts directly implants the pathogen onto vulnerable skin, creating new satellite lesions. This is why the infection appears to be "spreading." A study on impetigo prevalence specifically identified that factors such as frequency of hand washing and nail trimming are critical determinants in disease occurrence [3]. Therefore, breaking the itch-scratch cycle through education is the most impactful independent nursing action to control the infection's progression at the point of care.

Let’s analyze why the other options are not the priority:

Option 1: Apply warm compresses to the affected areas three times daily

While warm compresses can be a comfort measure to gently remove the characteristic honey-colored crusts before applying topical medication, this is an implementation step within the treatment regimen, not the overarching priority. The primary goal is to stop the infection from spreading further. Crust removal facilitates medication penetration but does not address the behavioral cause of autoinoculation.

Option 2: Encourage the child to wash hands frequently with antibacterial soap

This option is partially correct but critically incomplete. Hand hygiene is essential, but for a 4-year-old child, the cognitive and motor skills to perform effective hand hygiene independently are still developing. The priority intervention must involve the caregiver. Furthermore, simply encouraging a child to wash hands does not actively prevent the act of scratching, which is the immediate vector for spread. The nurse must teach the parent or guardian to assist with and supervise hand hygiene and to implement strategies to keep the child from scratching, such as keeping nails short and clean, and using distraction techniques. The research emphasizes that hygiene factors, including nail care, are significantly associated with impetigo prevalence [3].

Option 4: Administer oral antibiotics as prescribed by the healthcare provider

This option is incorrect because the scenario explicitly states the healthcare provider "prescribes topical antibiotic therapy." Topical antibiotics like mupirocin are the first-line treatment for mild, localized impetigo. Administering oral antibiotics would be outside the scope of the prescription provided and is reserved for more severe, widespread, or bullous impetigo cases. The nurse's role here is to administer the prescribed topical therapy correctly, not to initiate a different route of medication.

The core of nursing management for a contagious skin condition like impetigo is infection control. An outbreak control investigation for a related pathogen, Group A Streptococcus, highlighted that the implementation of enhanced infection prevention and control measures, including strict hand hygiene, was a cornerstone of managing the outbreak . While that context was a care home, the principle of breaking the chain of infection through hygiene and preventing contact with infectious material is identical. The nurse prioritizes educating the family on meticulous hand hygiene for both the child and caregiver, keeping the child’s fingernails short to reduce bacterial load and skin damage from scratching, and using physical barriers like mittens or long sleeves if necessary to prevent direct contact with lesions. This comprehensive behavioral intervention directly addresses the root cause of the spreading lesions and secondary infection noted on assessment.References (research sources)

## 임상 시나리오

Breaking the Impetigo Transmission CyclePrioritizing Non-Pharmacologic Interventions
The nurse's priority is to halt autoinoculation. Scratching transfers bacteria from under the nails to new skin sites, creating satellite lesions. Teach the child and family that keeping fingernails short and clean is as critical as the antibiotic itself.

Effective hand hygiene with plain soap and water is recommended. Antibacterial soap is not routinely necessary and may cause skin irritation. Focus on the mechanical action of washing after any contact with lesions.

CautionImpetigo is highly contagious until lesions are dry or the patient has been on effective antibiotics for 24 hours. Implement contact precautions and exclude the child from school or daycare during this period.

## 핵심 개념

- **Impetigo** — A highly contagious superficial bacterial skin infection, commonly caused by Staphylococcus aureus or Group A Streptococcus, characterized by honey-crusted lesions.
- **Autoinoculation** — The process by which a pathogen is transferred from one part of the body to another, often via scratching, leading to the spread of infection.
