CT scan or MRI differentiates CVA from other disorders and can differentiate between ischemic or hemorrhagic strokes. PT level would be done if the client is receiving anticoagulant therapy. Chest x-ray may be performed if respiratory concerns are indicated. Lumbar puncture would be done if subarachnoid bleeding is suspected.
