A 4-year-old is diagnosed with scabies. Which nursing interventions are appropriate? Select all that apply.

A. Wash bedding and clothing used in past 3 days in hot water and dry on high heat: Scabies mites can survive on fabrics for 2–3 days. Washing and drying on high heat kills mites and prevents reinfestation, making this an essential intervention. B. Apply permethrin 5% cream to the entire body and repeat application in 1 week: Permethrin is the first-line treatment for scabies. It must be applied from the neck down (including under fingernails) and repeated in 1 week to kill newly hatched mites. C. Isolate the child until all itching resolves: Itching may persist for weeks after treatment due to allergic reaction to dead mites. Isolation is unnecessary once treatment is started, as transmission risk decreases significantly. D. Treat only the symptomatic child, not close contacts: Close contacts should also be treated because scabies spreads easily through prolonged skin-to-skin contact. Treating only the symptomatic child risks reinfestation in the household. E. Provide oral antihistamines for nighttime pruritus: Antihistamines help reduce itching, especially at night, improving comfort and sleep. This supportive measure is appropriate alongside scabicidal treatment.
