A client with a history of polycystic kidney disease is complaining of the worst headache of his life and has been vomiting, complaining of photosensitivity, and having difficulty speaking. The client is most likely exhibiting symptoms for which condition?

Rationale: A. Acoustic neuroma is a benign tumor of the vestibulocochlear nerve (cranial nerve VIII) that typically causes unilateral hearing loss, tinnitus, and balance issues. It does not usually present with sudden, severe headache, vomiting, or acute neurological deficits such as difficulty speaking. This option does not match the client’s acute presentation. B. Ischemic stroke can cause sudden neurological deficits such as difficulty speaking, weakness, or visual changes, but it rarely presents with a sudden “worst headache of life” or severe vomiting. Headache can occur, but the combination of severe headache, vomiting, photosensitivity, and neurological changes is more consistent with a hemorrhagic event rather than an ischemic stroke. C. Ruptured cerebral aneurysm is the most likely cause of this client’s symptoms. Clients with polycystic kidney disease are at higher risk for cerebral aneurysms. Classic signs include a sudden, severe headache often described as “the worst headache of my life,” nausea and vomiting, photophobia, and neurological deficits such as difficulty speaking or altered consciousness. This presentation is consistent with subarachnoid hemorrhage resulting from aneurysm rupture, which is a medical emergency requiring immediate intervention. D. Migraine headaches can cause severe headache, photophobia, nausea, and vomiting, but they usually have a prodrome, are recurrent, and do not typically cause acute neurological deficits such as difficulty speaking. The sudden, extreme nature of this headache and associated symptoms makes migraine less likely.
