A nurse is caring for a 58-year-old client who presents to the emergency department with sudden onset of flashing lights, floaters, and a 'curtain-like' shadow in the peripheral vision of the right eye, diagnosed with rhegmatogenous retinal detachment scheduled for immediate surgical repair. Which nursing intervention should be the nurse's first priority?

Positioning with the head elevated and affected eye facing downward is the first priority to minimize further detachment and promote reattachment using gravity. Other interventions like pain management or eye patches are less urgent in this acute setting.

Preoperative Priority for Rhegmatogenous Retinal Detachment

The correct answer is Position the client with the head of the bed elevated and the affected eye facing downward. While the provided meta-analysis focuses on postoperative positioning, the physiological principle it highlights—using gravity to manipulate the position of the detached retina and any associated gas or fluid—is the critical concept that also guides preoperative nursing care. In a rhegmatogenous retinal detachment (RRD), a tear or hole allows vitreous fluid to seep under the retina, separating it from the underlying retinal pigment epithelium. The goal of immediate preoperative positioning is to prevent the progression of detachment and keep the macula safe. By positioning the client with the head elevated and the affected eye dependent (facing downward), gravity helps the detached retina fall back toward its anatomical position and prevents subretinal fluid from tracking under the macula, which is the central area responsible for sharp, detailed vision ^[1]. This intervention directly addresses the underlying pathophysiology and aims to preserve visual acuity before surgical repair can be performed.

Administering analgesics (Option 2) addresses the client's comfort, but RRD is typically painless; the primary sensation is visual disturbance, not acute pain. Pain management is a secondary priority to a measure that can directly limit the extent of permanent vision loss. Applying bilateral eye patches (Option 3) is an outdated and inappropriate intervention. While minimizing eye movement is a consideration, bilateral patching can cause sensory deprivation and anxiety without reliably immobilizing the eyes, as the eyes still move conjugately during sleep and with stimuli. The specific, gravity-dependent positioning is a far more targeted and effective intervention. Encouraging deep breathing exercises (Option 4) is a supportive measure for anxiety, which is a psychosocial need. In the hierarchy of nursing priorities, a physiological intervention that can directly alter the trajectory of a sight-threatening condition takes precedence over managing the emotional response to it. The immediate physical stabilization of the retinal detachment through positioning is the highest priority to optimize the client's visual outcome.
