A nurse is providing teaching to the parents of a child who has impetigo. Which of the following instructions should the nurse include in the teaching?

A. Seal soft toys in a plastic bag for 14 days: While contaminated objects can contribute to the spread of impetigo, sealing toys for 14 days is unnecessary. Standard precautions include regular cleaning and avoiding sharing personal items, but prolonged isolation of toys is not recommended. B. Administer acyclovir PO two times per day: Acyclovir is an antiviral medication used to treat herpesvirus infections, not bacterial infections like impetigo. Impetigo is commonly caused by Staphylococcus aureus or Streptococcus pyogenes and requires antibacterial treatment. C. Apply bactericidal ointment to lesions: Topical bactericidal ointments, such as mupirocin, are effective in treating localized impetigo lesions. Parents should be instructed to apply the ointment directly to affected areas, typically 2–3 times per day, to promote healing and prevent spread. D. Soak hairbrushes in boiling water for 10 min: While cleaning personal items is important to prevent reinfection, soaking hairbrushes in boiling water is excessive and may damage the items. Simple cleaning with soap and water or using disinfectant is sufficient to reduce bacterial contamination.
