In administering nystatin suspension to the gums of an infant with a candida infection, which approach should the practical nurse (PN) use?

Irrigate the infected area with medicated solution after applying sterile gloves.

Draw up the medication in a needle-less syringe which the infant can suck.

Use a gloved finger to rub the suspension over the infected area.

Measure the prescribed amount of solution into the infant's bottle.
