A nurse is talking with a client who is scheduled for surgery to repair retinal detachment. Which of the following preoperative instructions should the nurse include?

Rationale: A. For retinal detachment surgery, mydriatic (pupil-dilating) drops are often used for visualization during the procedure, not miotic (pupil-constricting) drops. This is incorrect. B. Limiting head movement is essential to prevent further detachment or worsening of retinal tears before surgery. This is the correct preoperative instruction. C. Patching both eyes is not necessary. The unaffected eye may be left open, and patching both can increase anxiety and risk of injury. D. Cool compresses are not part of the preoperative management of retinal detachment. They do not prevent progression or provide necessary protection.
