The nurse is precepting a new graduate nurse while caring for a client who is diagnosed with a Chiari type II malformation. Which statement by the new graduate nurse indicates the need for further teaching?

The statement that all sport activities including contact sports are acceptable for the client indicates the need for further teaching. Chiari type II malformation involves herniation of the cerebellar tonsils, brainstem, and other posterior fossa structures through the foramen magnum into the spinal canal, and it is almost always associated with myelomeningocele. Because the cerebellar tonsils and brainstem are displaced, there is increased risk of neurological injury with contact sports, particularly those involving head trauma or neck hyperextension. Contact sports and activities that risk head or cervical injury are generally contraindicated or require careful individualized evaluation. The statement that treatment depends on the degree of protrusion is accurate — some patients may be managed conservatively if asymptomatic while others require surgical decompression. The association with myelomeningocele is correct and must be assessed, as this co-occurrence is essentially universal in type II malformation. MRI is indeed the gold-standard imaging modality for characterizing Chiari malformations, confirming the anatomy and guiding surgical planning. Because the new graduate incorrectly stated that all sports, including contact sports, are acceptable without restriction, this reflects a dangerous misunderstanding of the safety precautions required for this condition and requires immediate correction.
