The nurse is providing care to a client having surgery to repair a retinal detachment to the left eye. Which intervention should the nurse implement during the postoperative period?

A. Teaching a family member to administer eye drops may be appropriate for some clients undergoing eye surgery, but it is not specifically indicated for retinal detachment repair. B. Encouraging deep breathing and coughing exercises is important for preventing respiratory complications but is not directly related to postoperative care for retinal detachment repair. C. Providing an eye shield to be worn while sleeping is important to protect the eye and prevent inadvertent trauma during the vulnerable postoperative period. It helps promote healing and prevents further injury to the eye. D. Obtaining vital signs every 2 hours during hospitalization is a general nursing intervention but is not specific to the postoperative care of a client undergoing retinal detachment repair.
