A nurse is discussing risks for infection with the parent of an infant. Which of the following should the nurse include?

Choice A reason: Pooling of blood in a cerebral space, such as a hematoma, can cause seizures by exerting pressure on brain tissue, disrupting neural activity. However, this is unrelated to febrile seizures, which are specifically triggered by rapid temperature changes, not vascular abnormalities, making this an incorrect cause.

Choice B reason: Febrile seizures are caused by a sudden rise in body temperature, often due to infections like viral illnesses. The rapid temperature increase stimulates neuronal hyperexcitability in young children, leading to seizures. This is the primary mechanism, typically seen in children aged 6 months to 5 years.

Choice C reason: Head or neck trauma causing a concussion can trigger seizures by disrupting brain function through inflammation or neuronal damage. However, febrile seizures are specifically linked to fever, not trauma. Concussive seizures require different management, making this an incorrect cause for febrile seizures.

Choice D reason: Structural brain defects, such as cortical dysplasia, can cause seizures by creating abnormal neural circuits. These are associated with epilepsy, not febrile seizures, which are benign and triggered by fever. Structural defects are a chronic condition, unlike the acute temperature-related mechanism of febrile seizures.

Choice A reason: Taking an axillary temperature is standard but not specific to myelomeningocele care. While monitoring for infection is important, it does not address the unique need to protect the exposed spinal sac, which is critical to prevent infection and trauma in this condition.

Choice B reason: Performing range of motion on the hips risks damaging the myelomeningocele sac, which contains nerve roots. Movement could cause sac rupture or neurological worsening, as the exposed neural tissue is highly vulnerable, making this action contraindicated in this fragile condition.

Choice C reason: Side-lying positioning may be used but is not the most critical action. It helps avoid pressure on the sac, but maintaining a dry, sterile dressing is paramount to prevent infection, a life-threatening complication in myelomeningocele due to exposed neural tissue.

Choice D reason: Maintaining a dry dressing over the myelomeningocele sac prevents infection and trauma to exposed neural tissue. A sterile, moist environment protects the sac until surgical repair, reducing the risk of meningitis or further neurological damage, indicating effective understanding of this condition’s care.
