Answer to Question 1

Retinal detachment is clinically manifested by flashes and floaters in the visual field. Flashes of light and floaters are not associated with cataracts, glaucoma, or conjunctivitis.

Answer to Question 2

3
A CT scan commonly uses contrast agents. These contrast agents often have iodine in them. The nurse should check to see if the client is allergic to iodine or shellfish. Shellfish also have iodine in them. The nurse does not need to shave the client's head, administer a sedative, or immobilize the head before movement.
