A nurse is providing discharge teaching to the parents of a school-age child following the placement of a ventriculoperitoneal shunt. The nurse should determine that the teaching was effective when the parents identify which of the following as an indicator that the shunt has been displaced?

Choice A reason: Keeping electrical wires hidden from view is essential to prevent toddlers from pulling on them, which can lead to electrical burns or other injuries. It is a proactive measure to ensure a safe environment for children who are naturally curious and prone to exploring with their hands.

Choice B reason: Turning pot handles toward the front of the stove is dangerous as it increases the risk of toddlers reaching up and pulling hot contents onto themselves. The correct practice is to turn pot handles toward the back of the stove to keep them out of reach of children.

Choice C reason: Encouraging outdoor activities between the hours of 11:00 and 13:00 can expose toddlers to the sun's peak intensity, increasing the risk of sunburn. It is safer to encourage outdoor activities outside these hours when the sun is less intense.

Choice D reason: Setting the water heater to 60°C (140°F) is too high and poses a scalding risk. The recommended temperature to prevent burns is 49°C (120°F), which is hot enough for household use but not so hot as to cause immediate burns upon contact.

Choice A reason: Treating everyone who came into close contact with the child is essential because scabies is highly contagious. The mites that cause scabies can easily spread to others through direct skin contact or by sharing personal items.

Choice B reason: Soaking combs and brushes in boiling water for 10 minutes is a good practice to kill any mites that may be present. However, it is not the primary method of treating scabies, which requires medication.

Choice C reason: Washing the child's hair with shampoo containing ketoconazole is not a standard treatment for scabies. Ketoconazole is an antifungal medication, and scabies is caused by mites, not fungi.

Choice D reason: Applying petroleum jelly to the affected areas is not an effective treatment for scabies. Scabies requires prescription medications, such as topical permethrin or oral ivermectin, to eliminate the mites.
