A nurse is providing discharge teaching to a client who has completed radiation therapy for a brain tumor. Which statement by the client indicates a need for further education?

Discharge teaching for post-radiation brain tumor patients requires understanding oncology and pharmacology. Knowledge of medication adherence, symptom monitoring for increased intracranial pressure, and integumentary protection is needed. Identifying misconceptions ensures patient safety and prevents potential neurological relapse or secondary injury. Choice A rationale Abrupt cessation of medications, especially anticonvulsants or steroids used in neuro-oncology, can trigger rebound edema or seizures. Maintaining therapeutic blood levels is critical for managing potential complications after radiation therapy has concluded to ensure neurological stability. Choice B rationale Headaches and visual disturbances are primary indicators of increased intracranial pressure or tumor recurrence. Patients must recognize these signs as urgent neurological changes that require immediate medical evaluation to prevent brain herniation or permanent functional loss. Choice C rationale Radiation therapy damages the DNA of skin cells, leading to thinning and increased sensitivity. Protecting the scalp from ultraviolet radiation prevents severe dermatitis and secondary burns on tissue that already has compromised healing capabilities. Choice D rationale Gradual reintegration into daily life is standard post-treatment advice. While energy levels dictate activity, resuming normal routines as tolerated is appropriate, provided the patient avoids hazardous activities if they have residual neurological deficits or seizure risks.
