The RN is changing the diaper of an 8-month-old and notes sensitivity and erythema with papules and pustules around the rash. Which nursing action is appropriate?

A. Treat with petroleum jelly only and be sure to change the diaper no more than two times per day: Petroleum jelly can provide a protective barrier, but infrequent diaper changes increase moisture and irritation, worsening the rash. The presence of papules and pustules suggests a fungal component, which requires more than barrier protection alone. B. Start oral antibiotics immediately and apply high heat to the area: Oral antibiotics are not indicated unless there is a confirmed bacterial infection, and unnecessary use can disrupt normal flora. Applying heat can further irritate the skin, increase inflammation, and promote microbial growth in the moist diaper environment. C. Administer topical antifungal as per provider order and ensure to keep area clean and dry: The presence of erythema with papules and pustules is characteristic of candidal diaper dermatitis. Topical antifungal therapy targets the underlying yeast infection, while maintaining a clean, dry environment helps reduce moisture that promotes fungal growth and supports healing. D. Administer antibiotic ointment to area: Antibiotic ointments are used for bacterial infections, not fungal infections like candidiasis. Using antibiotics in this case would not treat the underlying cause and may even worsen fungal overgrowth by altering normal skin flora.
