A nurse is conducting a postoperative assessment on an infant who has just had a ventriculoperitoneal shunt placed for hydrocephalus. Which assessment finding would indicate a malfunction in the shunt?

Choice A reason: Lifting and clearing drainage from the chest tube is not necessary unless there is a blockage, which is not indicated by the water level changes.
Choice B reason: Inspecting the tube insertion site for leaking is important but not related to the observation of water level changes in the water-seal chamber.
Choice C reason: This is the correct choice. The water level rising during inspiration and falling during expiration is a normal finding that indicates the chest tube is functioning properly.
Choice D reason: Auscultating lungs for unequal breath sounds is part of the assessment but does not address the observed water level changes in the water-seal chamber.

Choice A reason: Allowing parents to hold their infant is a compassionate act that acknowledges their need for closure and can help them begin the grieving process.

Choice B reason: Interviewing parents to determine the cause of the incident is not considered supportive care; it may be part of an investigation but does not provide comfort.

Choice C reason: Providing mementos can be a cherished way for parents to remember their infant and can offer some solace during a difficult time.

Choice D reason: Advising parents about the necessity of an autopsy is not supportive care; it is a medical decision that should be discussed with sensitivity to the parents' feelings and needs. Autopsies can be important for understanding SIDS and preventing future occurrences.
