A nurse is reinforcing preoperative teaching with a client who is scheduled for retinal detachment repair. Which of the following instructions should the nurse include in the teaching?

Choice A rationale Retinal detachment occurs when the neural retina separates from the underlying retinal pigment epithelium. To prevent the detachment from enlarging due to gravity or mechanical force, head movement must be strictly restricted. Minimizing movement helps the retina remain as stable as possible against the choroid before surgical intervention. This is a critical preoperative safety measure to preserve as much visual field as possible and to ensure the best possible surgical outcome for the patient. Choice B rationale While rest is important, the instruction to simply lie down is too vague. The patient often needs to be placed in a specific position based on the location of the retinal tear to allow gravity to help the retina settle back into place. For example, the patient might need to lie on the side of the affected eye. Restricting head movement is more precise and vital than general bed rest, as sudden jerks can worsen the retinal separation significantly. Choice C rationale Applying cool compresses is not indicated for a retinal detachment. Cool compresses are typically used to reduce edema or itching in conditions like conjunctivitis or periorbital trauma. In the case of a detached retina, the issue is structural and internal, involving the separation of tissue layers at the back of the eye. Compresses provide no therapeutic benefit for reattaching the retina and could potentially cause unnecessary pressure on the globe, which should be avoided. Choice D rationale Patching both eyes, known as bilateral patching, was once a common practice to minimize eye movement (consensual movement). However, modern preoperative protocols often focus on patching only the affected eye or simply enforcing strict bed rest with head immobilization. Patching both eyes can be very distressing for the patient, increasing anxiety and the risk of falls or disorientation. Restricting head movement is the primary nursing priority to prevent further detachment before the surgical repair.
