A nurse prepares to apply topical permethrin for a child with scabies.What should be included in the instructions?

Choice A rationaleFor scabies treatment with topical permethrin in children, the medication should be applied from the neck down to the toes, ensuring all skin surfaces are covered because scabies mites can burrow anywhere on the body. The permethrin should be left on for the prescribed duration, typically 8-14 hours or overnight, to allow sufficient contact time to kill the mites and their eggs.Choice B rationaleApplying permethrin only to affected areas may not be sufficient to eradicate scabies because mites can be present on areas of the skin that do not yet show visible signs of infestation or itching. Complete coverage is necessary to ensure treatment success.Choice C rationaleApplying permethrin only to the scalp is inadequate for treating scabies, as the mites commonly infest other areas of the body. While scabies can affect the scalp, especially in infants and young children, treatment must extend to all skin surfaces from the neck down.Choice D rationaleA hot bath should be avoided before applying permethrin. Hot water can irritate the skin and increase absorption of the medication, potentially leading to systemic toxicity or reduced effectiveness. Permethrin is typically applied to cool, dry skin.
