A nurse is providing teaching to the parents of a child who has had a shunt inserted as treatment for hydrocephalus. The parents demonstrate understanding of the teaching when they make what statement?

Choice A rationale While a shunt insertion for hydrocephalus aims to drain excess cerebrospinal fluid and reduce intracranial pressure, thereby minimizing brain damage, it does not completely eliminate the risk of developmental problems. The extent of pre-existing neurological damage influences long-term outcomes, and some children may still experience learning disabilities or motor deficits requiring ongoing therapy and support. Choice B rationale The risk of shunt infection is present throughout the device's life, although the greatest risk does occur in the early post-operative period, typically within the first few months. Infections can be caused by skin flora introduced during surgery and can lead to serious complications like ventriculitis or septicemia, often requiring shunt removal and IV antibiotics. Choice C rationale Shunts have a fixed length; as the child grows, the distal catheter (the end draining the fluid) may no longer reach the peritoneal cavity or atrium, leading to shunt malfunction. Furthermore, components can fail over time due to wear or blockage, necessitating surgical revisions or replacement throughout the individual's lifetime to maintain proper cerebrospinal fluid drainage. Choice D rationale A ventriculoperitoneal or ventriculoatrial shunt is a palliative measure that manages the primary complication of hydrocephalus, which is increased intracranial pressure. However, shunts are prone to complications such as malfunction due to blockage, disconnection, or infection, and they do not cure the underlying cause, meaning that further complications remain a possibility.
