A parent of a child with impetigo says, "I will stop the antibiotic when the sores look better." What is the best response by the nurse?

1. 1"Stop the antibiotic as soon as the sores heal, to avoid side effects."
2. 2"Finish the whole course to prevent the infection from coming back and antibiotic resistance."
3. 3"Give the antibiotic only on days when new sores appear."
4. 4"Antibiotics are not needed because impetigo never gets better with them."
