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?

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.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a child with Impetigo, a highly contagious superficial bacterial skin infection. The core theme is infection control and preventing the spread of infection, which is a fundamental nursing responsibility. The pathophysiology involves Staphylococcus aureus or Streptococcus pyogenes bacteria causing honey-colored, crusted lesions. Scratching breaks the skin barrier, spreads the bacteria to other body sites (auto-inoculation), and can lead to secondary infection.

Answer Rationale: Key Point! The priority intervention is Teaching proper hand hygiene and preventing scratching of lesions. This directly addresses the two main problems in the scenario: transmission and interference with healing. Hand hygiene breaks the chain of infection by removing pathogens. Preventing scratching stops auto-inoculation (spreading to other body parts) and cross-contamination (spreading to others), protects the integrity of the lesions to allow healing, and reduces the risk of deeper secondary infection. This is a patient/family education intervention, which is often the nurse's primary and most impactful role in managing communicable diseases in the outpatient setting.

Distractor Analysis: Watch out for confusion! Option ① (Apply warm compresses) may provide comfort and soften crusts, but it is not the priority. It is a supportive measure, not the primary action to control the spread of infection.
Option ② (Encourage frequent handwashing with antibacterial soap) is a component of the correct answer but is incomplete and potentially problematic. While handwashing is crucial, antibacterial soap is not typically recommended for routine use in children as it can disrupt skin flora and contribute to bacterial resistance. Plain soap and water are effective and preferred.
Option ④ (Administer oral antibiotics) is an important medical intervention, especially for widespread or bullous impetigo. However, the question specifies that topical antibiotic therapy was prescribed. The nurse's role is to administer or teach administration of the prescribed therapy. Jumping to oral antibiotics when not ordered is incorrect. Even if oral antibiotics were ordered, administration follows the priority of first teaching measures to prevent spread.

Related Concepts: This integrates concepts of chain of infection, standard precautions, principles of patient education, and pediatric skin care. Understanding that impetigo is a contact precaution condition is key. The nursing process guides us: Assessment (honey-crusted lesions, scratching) leads to Nursing Diagnosis (Risk for Infection Transmission, Impaired Skin Integrity). Planning and Implementation must first target the most immediate threat to the patient and others—which is spreading the infection. Concept Summary • Disease: Impetigo – Contagious superficial bacterial skin infection. • Pathogens: Staphylococcus aureus (most common), Streptococcus pyogenes. • Key Feature: Honey-colored, crusted lesions; highly contagious via direct contact. • Nursing Priority: Infection control – Hand hygiene and preventing scratching. • Treatment: Topical antibiotics (e.g., mupirocin) for limited lesions; oral antibiotics for extensive cases. • Complication: Cellulitis, post-streptococcal glomerulonephritis (rare).
Side-by-Side Comparison!

Skin Condition	Key Characteristics	Contagious?	Nursing Priority
Impetigo	Honey-colored crusts, vesicles/bullae, face/arms	Yes (Contact)	Prevent spread (hand hygiene, no scratching)
Atopic Dermatitis (Eczema)	Dry, itchy, inflamed skin; lichenification	No	Skin hydration, itch control, identify triggers
Contact Dermatitis	Erythema, vesicles in pattern of allergen/irritant exposure	No	Remove offending agent, soothe skin
Cellulitis	Deep skin infection: red, warm, tender, swollen area; often with fever	No (Not typically person-to-person)	Administer systemic antibiotics, monitor for sepsis

Anatomy, Physiology & Pharmacology Points • Skin Barrier: The stratum corneum is the first line of defense. Scratching compromises this barrier, allowing bacteria entry and spread.
• Bacterial Transmission: Impetigo spreads via direct contact with lesions or fomites (e.g., towels, toys).
• Topical Antibiotic: Mupirocin ointment is common. Nursing point: Apply a thin layer after gentle cleansing, cover if possible to prevent child from touching/rubbing it off.
Memory Tips • H.I.P. for Impetigo: Hand hygiene, Isolating personal items (no sharing), Prevent scratching.
• Think "STOP the SPREAD": Scratching Transfers Organisms & Promotes Redness, Exudate, and Auto-inoculation/Dissemination.
High-Frequency NCLEX Topics NCLEX loves testing infection control priorities and patient education for communicable diseases. Impetigo is a classic pediatric example. Remember: Your first action is often to teach measures that stop transmission (hand hygiene, covering lesions, not sharing items) before performing other comforting or treatment-focused tasks.
Watch Out for Question Variations! • If the question asks for the first action upon suspecting impetigo: The answer might shift to initiating contact precautions (donning gloves for assessment).
• If lesions are widespread or bullous: The priority may include preparing to administer oral antibiotics as they are first-line for extensive disease.
• If a sibling at home has a compromised immune system: The priority teaching would emphasize strict isolation of the infected child's belongings and possibly temporary separation.

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a busy pediatric clinic. A mother brings in her 4-year-old son, Leo, pointing to "crusty sores" around his nose and on his forearm that appeared two days ago. Leo is constantly scratching them. His 2-year-old sister at home has eczema.

Nursing Intervention Strategy: 1. Assessment: Don gloves. Inspect lesions (note honey-colored crusts, erythematous base). Assess for fever, lymphadenopathy. Ask about recent skin breaks, other sick contacts, and the sister's condition.
2. Immediate Action & Education (Priority): Before even discussing medication, you say: "Leo, let's practice not touching your sores. Can you show me how to wash hands with soap?" Teach mother and child proper 20-second handwashing technique. Emphasize washing after touching lesions. Teach that fingernails should be kept short and clean. Suggest having Leo wear clean, soft cotton mittens or long sleeves at night to prevent unconscious scratching.
3. Medication & Care Teaching: After the provider prescribes mupirocin ointment, teach the mother: "Gently wash the area with warm water and a soft cloth to remove crusts, then pat dry. Apply a pea-sized amount of this ointment to each lesion three times a day. Use a clean cotton-tip applicator for each sore to avoid cross-contamination. Wash your hands before and after application."
4. Environmental & Family Education: Instruct the family not to share towels, washcloths, bedding, or clothing. Leo's linens should be washed daily in hot water. Disinfect toys that are mouthed or handled frequently. Due to the sister's eczema (compromised skin barrier), advise extra vigilance to prevent contact between siblings until lesions are crust-free.
5. Evaluation & Follow-up: Instruct the mother to monitor for signs of worsening infection (increased redness, swelling, pain, fever) and to return if lesions do not improve in 3-4 days. Stress the importance of completing the full course of topical antibiotic even if it looks better.

Patient Safety and Precautions: • Key Point! Contact Precautions: Use gloves for any contact with lesions or potentially contaminated items. In a hospital setting, the child would be placed in contact isolation.
• Medication Caution: Ensure the topical antibiotic is for external use only. Avoid contact with eyes. Monitor for local skin reactions.
• Contraindication: Do not use topical neomycin frequently due to high risk of allergic contact dermatitis.
Nursing Procedure & Medication Flow Procedure for Topical Antibiotic Application: 1. Gather supplies: Prescribed ointment, clean gloves, warm water, soft cloth, cotton-tip applicators. 2. Perform hand hygiene, don gloves. 3. Gently cleanse affected area with warm water to soften and remove crusts. Pat dry with a clean towel. 4. Apply a thin layer of ointment to each lesion using a new, clean applicator for each. 5. Cover with a light gauze dressing if needed to prevent spread from oozing lesions or to keep child from touching it (especially on face, this may not be practical). 6. Remove gloves, perform hand hygiene. 7. Document: Location/number of lesions, appearance, procedure performed, and patient/family education provided.
A Word from Your Senior Nurse "In pediatrics, skin infections like impetigo are common, but their impact can be huge if they spread through a daycare or to a vulnerable sibling. Your role isn't just to put on ointment. You are the detective identifying how it spread, the teacher empowering a 4-year-old to 'be a handwashing superhero,' and the family counselor easing a mom's worry. When you see 'priority' on the NCLEX, think: 'What can I do right now that will have the biggest impact on stopping this problem and keeping others safe?' Often, that answer is education. Connecting that teaching to a tangible action—like practicing handwashing together—turns theory into real nursing care that makes a difference."
