Step-by-step explanation:
When collecting the medical history from the caregiver of a new client with a bipolar disorder diagnosis scheduled to begin lithium therapy, the priority statement to report is the patient's history of epilepsy. Epilepsy is important to report because lithium can increase the risk of seizures in individuals with a history of epilepsy. It is crucial to ensure that the healthcare team is aware of this information so that they can consider appropriate treatment options and monitor the patient closely for any potential complications.
