Correct Answer is D
Explanation
Choice A rationale
Allowing the client to ambulate one day after a detached retinal repair is not recommended. Ambulation can increase intraocular pressure and disrupt the healing process of the retina. The client should be advised to limit physical activity to prevent any strain on the eye.
Choice B rationale
Removing the eye patch during the day is not advisable as it can expose the eye to potential injury or infection. The eye patch helps protect the eye and maintain the correct position for healing. It should be worn as directed by the healthcare provider.
Choice C rationale
Encouraging coughing and deep-breathing exercises is not appropriate for a client who has undergone retinal repair. These activities can increase intraocular pressure and risk detachment of the retina. The client should avoid activities that cause strain or pressure on the eyes.
Choice D rationale
Avoiding reading and writing is crucial for a client one day postoperative following a detached retinal repair. These activities can cause rapid eye movements and strain, which can interfere with the healing process and reattachment of the retina. The client should be advised to rest their eyes and avoid any activities that require intense focus or eye movement.
