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: Soaking hairbrushes in boiling water is a good practice for decontamination, but it is not specific to the treatment of impetigo, which is a bacterial skin infection.

Choice B reason: Acyclovir is an antiviral medication and would not be effective against impetigo, which is caused by bacteria, typically Staphylococcus aureus or Streptococcus pyogenes.

Choice C reason: Sealing soft toys in a plastic bag for 14 days may help to prevent the spread of infection, but it is not a direct treatment for impetigo itself.

Choice D reason: Applying a bactericidal ointment, such as mupirocin, is a standard treatment for impetigo. It helps to eliminate the bacteria causing the infection and promotes healing of the skin lesions.

Choice A reason: Clearing the area of hard objects is crucial to prevent injury during a seizure. It helps to ensure that the child does not hit or get hurt by any objects in the vicinity while experiencing convulsions.

Choice B reason: Minimizing movement of the limbs is not recommended as it can cause injury to the child. Instead, the child should be allowed to move freely without restraint to avoid causing harm to their joints or muscles.

Choice C reason: Inserting a tongue blade between the teeth is an outdated and dangerous practice. It can cause injury to the child's mouth or teeth and may lead to choking if the tongue blade breaks.

Choice D reason: Placing the child in a prone position is not advised as it can obstruct the airway. The child should be placed on their side in the recovery position to keep the airway clear and allow fluids to drain from the mouth.
