The parent of an adolescent tells the clinic nurse, "My child has athlete's feet. I have been applying triple antibiotic ointment for two days, but there has been no improvement." Which instruction should the nurse provide?

A. Applying too much ointment can deter its effectiveness. Apply a thin layer to prevent maceration: Athlete’s foot is a fungal infection, and antibiotic ointments are not effective against fungi. The issue is the inappropriate choice of medication. B. Continue using the ointment for a full week, even after the symptoms disappear: Continuing an ineffective antibiotic ointment will not resolve a fungal infection. Athlete’s foot requires antifungal treatment, prolonging antibiotic use delays appropriate management. C. Antibiotics take two weeks to become effective against infections such as athlete's foot: Athlete’s foot is not caused by bacteria, so antibiotics will never be effective. Antifungal creams, sprays, or powders are required, along with good foot hygiene practices. D. Stop using the ointment and encourage complete drying of feet and wearing clean socks: The most appropriate instruction is to stop the antibiotic and focus on antifungal management and foot care. Keeping feet dry, wearing clean socks, and using antifungal medication are key
