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?
1Position the client with the head of the bed elevated and the affected eye facing downward✓ 정답
2Administer prescribed analgesics to manage eye pain
3Apply bilateral eye patches to prevent eye movement
4Encourage the client to perform deep breathing exercises to reduce anxiety
해설
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.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention for a patient with a Rhegmatogenous retinal detachment. This is a true ophthalmic emergency where the neurosensory retina separates from the underlying retinal pigment epithelium due to a tear or hole, allowing vitreous fluid to seep underneath and cause progressive detachment. The classic symptoms are flashes of light (Photopsia), new floaters, and a shadow or curtain over the visual field.
Answer Rationale: The immediate goal before surgical repair is to Key Point!prevent the detachment from progressing. Positioning the patient with the head of the bed elevated and the affected eye facing downward (or in a dependent position as per specific surgeon orders) uses gravity to keep the detached retina in contact with the choroid and may prevent further seepage of fluid through the retinal break. This is the single most important pre-operative nursing action to preserve vision.
Distractor Analysis: Watch out for confusion! Option ② (Administer analgesics): While the patient may be anxious, significant pain is not a hallmark of uncomplicated retinal detachment. Severe pain suggests other emergencies like acute angle-closure glaucoma. Pain management, while important for comfort, is not the first priority for preserving vision.
Option ③ (Apply bilateral eye patches): Patching is not the standard immediate intervention for retinal detachment. In fact, restricting all eye movement is less critical than specific positioning. Bilateral patching can increase anxiety and disorientation and is not the priority action.
Option ④ (Encourage deep breathing): Reducing anxiety is a supportive measure, but it does not address the immediate, vision-threatening pathophysiological process. It is a secondary intervention.
Related Concepts: The priority follows the principle of stabilizing the condition to prevent further harm before definitive treatment. This is analogous to immobilizing a fracture before surgery. The specific positioning order may vary (e.g., "lie on the side opposite the detachment" to make the retinal hole the most dependent part), but the core principle of using gravity to tamponade the detachment is constant.

Immediate Nursing Priority
Pathophysiology
Rhegmatogenous Retinal Detachment
Flashes, floaters, curtain-like shadow (painless)
Position to limit detachment (gravity-dependent)
Tear/hole allows vitreous fluid under retina.
Acute Angle-Closure Glaucoma
Severe eye pain, headache, nausea, vomiting, blurred vision, halos
Administer prescribed IOP-lowering meds (e.g., osmotic agents, pilocarpine)
Sudden blockage of aqueous outflow, causing rapid IOP rise.
Central Retinal Artery Occlusion (CRAO)
Sudden, profound, painless unilateral vision loss (seconds), "cherry-red spot" on fundoscopy
Immediate ophthalmology consult; may attempt to lower IOP or provide ocular massage
Embolus blocks central retinal artery, causing retinal ischemia.
Anatomy, Physiology & Pharmacology Points
Anatomy: The retina is the light-sensitive neural layer. The Retinal Pigment Epithelium (RPE) is the outer layer that supports the photoreceptors. Detachment occurs between these layers.
Physiology:
Gravity-dependent positioning aims to make the retinal tear/hole the most dependent part of the eye. This allows the buoyant force of the subretinal fluid to push the retina back against the RPE, and may also allow the tear to settle against the choroid.
Pharmacology: Pre-operative medications are not typically the priority. Post-operatively, patients will use antibiotic and steroid eye drops to prevent infection and control inflammation. Mydriatic (pupil-dilating) drops are also commonly used.
Memory Tips
Acronym for Symptoms: "Floaters, Flashes, and a Falling curtain" (The 3 F's of Retinal Detachment).
Positioning Logic: Think "Hole down, save the town." Position the retinal hole in the most dependent (lowest) position to use gravity as a helper.
Priority: Remember ABCs with a twist – in eye emergencies, "Positioning and Preservation of vision" can be the immediate life (vision)-saving intervention.
High-Frequency NCLEX Topics
Retinal detachment is a classic NCLEX topic testing prioritization and understanding of pathophysiology-based interventions. The exam loves to present the classic symptom triad and ask for the first nursing action. Remember: In an acute, vision-threatening situation where surgery is pending, your job is to prevent the problem from getting worse. Non-urgent comfort measures are almost never the correct priority answer.
Watch Out for Question Variations!
Symptom Identification: "A client reports sudden onset of flashing lights and a shadow in their vision. The nurse should recognize these as signs of which condition?"
Post-Operative Care: After pneumatic retinopexy (gas bubble injection), the priority becomes maintaining specific head positioning (e.g., face down) for days to weeks to keep the bubble against the retinal tear.
Patient Education: "Which instruction is most important for a client at high risk for retinal detachment (e.g., high myopia, post-cataract surgery)?" Answer: "Report any new flashes, floaters, or shadows in vision immediately."
Nursing Clinical Practice GuideClinical Scenario: Mr. Johnson, 58, is in your ED bed. He's anxious but alert, holding a tissue. He says, "It was like a camera flash went off, then I saw black spots, and now it's like a gray curtain is closing from the side on my right eye." He denies pain. Vital signs are stable. The ophthalmologist has diagnosed a superior temporal retinal detachment in the right eye and scheduled an urgent vitrectomy for 2 hours from now.
Nursing Intervention Strategy:
1. Assessment: Quickly confirm the diagnosis and laterality with the chart/physician. Perform a focused assessment: document visual acuity per protocol (if possible), confirm which eye and describe the shadow's location (e.g., "curtain starting in superior visual field"). Assess anxiety level.
2. Priority Action: Implement positioning orders immediately. Clarify with the ophthalmologist: "To confirm, you want the head of bed elevated 30 degrees and the patient to lie on his left side, so the right eye (with the superior tear) is facing down, correct?" Once confirmed, assist the patient into this position. Use pillows for support. Explain the rationale clearly: "This position uses gravity to help keep the retina in place and prevent more fluid from going under it until the doctor can fix it."
3. Ongoing Care & Preparation: Keep the patient in the ordered position. Minimize sudden head movements. Administer pre-operative medications as ordered. Provide calm, clear explanations to reduce anxiety. Do not patch the eye unless specifically ordered (it can increase fear and is not therapeutic here).
Patient Safety and Precautions:
Contraindications: Do not administer medications that increase intraocular pressure (IOP) or cause significant vasodilation unless specifically indicated and ordered.
Key Monitoring: Monitor for changes in symptoms (e.g., reports that the "curtain" has advanced centrally). This indicates progression and should be reported to the surgeon immediately.
Safety: Because the patient's vision is compromised, maintain a clear pathway to the bathroom, keep call light within easy reach, and orient them to the environment. Assist with ambulation as needed.
Nursing Procedure & Medication FlowProcedure: Implementing Pre-op Positioning for Retinal Detachment
1. Verify physician order for specific positioning (e.g., "HOB elevated 30°, right side-lying").
2. Explain the procedure and its critical importance to the patient and family.
3. Adjust the bed to the ordered angle.
4. Assist the patient to turn onto the specified side. Use pillows behind the back and between knees for comfort and stability.
5. Ensure the affected eye is the dependent (lower) eye.
6. Place necessary items (water, call light) within easy reach on the side the patient is facing.
7. Reassess position and comfort every 30-60 minutes. Reposition within the constraints of the order (e.g., can shift slightly but must keep the affected eye down).
8. Document: Position implemented, patient tolerance, and any change in symptoms.
Medication Notes: Pre-op medications are minimal. Post-op, the patient will be on a regimen of eye drops. Key education points:
Steroid Drops (e.g., prednisolone): Reduce inflammation. Teach signs of increased IOP (eye pain, headache) and systemic absorption (mood changes with long-term use).
Antibiotic Drops (e.g., moxifloxacin): Prevent infection. Teach strict aseptic technique: don't let dropper touch eye, wash hands before and after.
Mydriatic/Cycloplegic Drops (e.g., atropine): Keep pupil dilated and eye at rest. Will cause blurry vision and photophobia. Advise wearing sunglasses outdoors.
A Word from Your Senior Nurse
"Eye emergencies are scary for patients because the threat to vision is so visceral. Your calm, competent execution of a simple yet critical intervention—like positioning—demonstrates true nursing expertise. You're not just following an order; you're actively participating in saving someone's sight. In moments like these, your ability to connect the 'why' (the pathophysiology of the detachment) to the 'what' (the specific positioning) is what makes you a nurse, not a technician. Carry that understanding from your studies into practice, and you'll provide care that is both clinically excellent and deeply human."
Rhegmatogenous Retinal Detachment — The most common type of retinal detachment, caused by a break (tear or hole) in the retina that allows vitreous fluid to pass into the subretinal space, separating the neurosensory retina from the retinal pigment epithelium.
Photopsia — The perception of flashes of light, often described as seeing "stars" or "lightning streaks." A classic symptom of retinal traction or detachment.
Vitreous Humor — The clear, gel-like substance that fills the space between the lens and the retina. In rhegmatogenous detachment, this fluid flows through a retinal break, causing detachment.
Gravity-Dependent Positioning — A therapeutic positioning strategy used pre-operatively for retinal detachment. Positioning the retinal break in the most dependent part of the eye uses gravity to help re-approximate the retina and prevent further fluid accumulation.
Pneumatic Retinopexy — A surgical procedure for retinal detachment where a gas bubble is injected into the vitreous cavity. The patient must maintain specific head positioning post-op to keep the bubble against the retinal tear.
