A 2-year-old child with a ventricular shunt has a temperature of 101.5°F (38.6°C), is irritable, and has a heart rate of 160 bpm. Which of the following is the priority nursing action?

Choice A rationale The constellation of fever (101.5°F or 38.6°C), irritability, and tachycardia (160 bpm, normal for a 2-year-old is ∼ 80-130 bpm) in a child with a ventricular shunt is highly suggestive of a shunt infection (ventriculitis or meningitis). A shunt infection can lead to septicemia and shunt malfunction, potentially causing rapidly increased intracranial pressure (ICP). Given the high morbidity, this finding requires immediate notification of the provider for prompt diagnostic workup (e.g., shunt tap) and empiric antibiotics. Choice B rationale While tachycardia and irritability can sometimes be non-specific symptoms, a fever of 101.5°F is abnormal. The presence of a ventricular shunt significantly raises the index of suspicion for shunt infection, a neurosurgical emergency, which is a life-threatening condition. Documenting and observing without immediate intervention is dangerously negligent given the clinical picture. Choice C rationale Administering antipyretics addresses only the fever, a symptom, and does not treat the underlying potentially fatal shunt infection. Delaying notification to reassess in one hour risks rapid neurological deterioration, as shunt infections can progress quickly to sepsis, severe ventriculitis, or uncompensated increased intracranial pressure (ICP). Immediate medical evaluation is the priority. Choice D rationale Encouraging oral fluids is a supportive measure for fever and dehydration, but it is not the priority for a child highly suspected of having a ventricular shunt infection. Oral fluid intake can be impaired due to irritability and potential nausea/vomiting associated with increased intracranial pressure, and this action delays definitive diagnosis and treatment of the infection.
