The Nurse Is Working with the Family of a Child

The nurse is working with the family of a child who is bothered by a wart and tends to pick at it. The family has been trying to remove the wart with a nonprescription product. The nurse assesses to see if the family is using the correct technique with a topical agent such as Duofilm, Mediplast, or Trans-plantar to treat the wart. Which of the following statements by the family would indicate correct technique?

A) "We used an emery board to sand the wart, soaked it in warm water, applied the medication, and then dry, reapplied it to cover the whole wart."
B) "We put the topical agent on the wart and covered it with an Elastoplast bandage wrapped with an Ace bandage to prevent picking."
C) "We cut the wart off, applied the medication, and left it open to the air."
D) "We applied a strong vinegar solution and then applied the medication."
