A nurse is caring for a client who reports sudden onset of flashing lights and a "curtain-like" shadow in the peripheral vision of the right eye. Which nursing action should be the priority?

해설
Positioning with head elevated and affected eye dependent is the priority to use gravity for reattachment and prevent further detachment. Immediate ophthalmologic consultation is essential.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing action for a patient with symptoms highly suggestive of Retinal detachment. The classic symptoms are flashing lights (photopsia) and a "curtain" or "shadow" in the peripheral vision. This is an ophthalmologic emergency. The pathophysiology involves fluid (vitreous humor) seeping through a tear or hole in the retina, separating the neurosensory retina from the underlying retinal pigment epithelium. This separation cuts off the blood supply to the retina, leading to rapid and permanent vision loss if not treated promptly.

Answer Rationale: Key Point! The priority action is to minimize further detachment. Positioning the client with the head elevated and the affected eye dependent (e.g., lying on the side of the unaffected eye) uses gravity to help keep the detached retina in place or settle back toward the choroid. This positioning is a critical, immediate nursing intervention while arranging for urgent ophthalmologic evaluation and potential surgical repair (e.g., pneumatic retinopexy, scleral buckle).

Distractor Analysis:
  • Option 1 (Administer analgesic): Watch out for confusion! Retinal detachment is typically painless. The primary complaint is visual disturbance, not pain. Administering an analgesic addresses a non-existent problem and delays critical care.
  • Option 2 (Apply bilateral eye patches): Patching is not the standard immediate intervention for retinal detachment. It may be used post-operatively. More importantly, patching both eyes can increase anxiety and disorientation. The priority is positioning, not immobilization.
  • Option 4 (Encourage eye exercises): This is contraindicated. Any movement of the eye, especially rapid or extreme movements, can increase intraocular fluid dynamics and potentially worsen the detachment. The patient should be instructed to limit eye movement and rest.
Related Concepts: The nursing priority follows the ABCs and urgent needs principle. While not an airway or breathing issue, this is a "sensory (vision) emergency" where minutes to hours matter to preserve function. Immediate actions focus on preventing progression until definitive treatment.

Concept Summary
ConceptKey Points
Retinal DetachmentSeparation of neurosensory retina from RPE. Painless. Symptoms: Floaters, flashes, curtain-like shadow. Ophthalmologic emergency.
Priority Nursing ActionPosition to limit detachment: Head elevated, affected eye dependent. Minimize eye movement. Prepare for urgent ophthalmology consult.
Contraindicated ActionsEye exercises, rubbing eyes, strenuous activity, delaying evaluation.
Definitive TreatmentSurgical procedures: Pneumatic retinopexy, scleral buckle, vitrectomy.

Corneal AbrasionForeign body sensation, pain, tearing, photophobiaYesAdminister analgesic/cycloplegic, antibiotic ointment, eye patch (sometimes), educate on not rubbing eye

Anatomy, Physiology & Pharmacology Points
  • Anatomy: The retina is the light-sensitive neural layer. It is nourished by the choroid underneath. Detachment separates it from its blood supply.
  • Pathophysiology: Often preceded by posterior vitreous detachment (PVD), causing traction and a retinal tear. Liquid vitreous enters the tear, peeling the retina away.
  • Pharmacology (Post-op): Treatment may involve intraocular gas or oil bubbles. Patients must maintain specific head positions (posturing) for days to weeks to keep the bubble in contact with the retina.

Memory Tips
  • Think "Gravity is your friend": For detachment, position so gravity pulls the retina back down (affected eye down).
  • Acronym for Symptoms: "Floaters, Flashes, Field loss (curtain)" – the 3 Fs of Retinal Detachment.
  • No Pain, Big Problem: Remember it's painless. If a question mentions severe pain, think glaucoma or infection instead.

High-Frequency NCLEX Topics NCLEX loves to test priority-setting in emergencies. Retinal detachment is a classic example where a simple, non-pharmacological nursing action (positioning) is the immediate priority before the doctor arrives or definitive treatment begins. Be ready to distinguish it from other eye emergencies.

Watch Out for Question Variations!
  • Symptom Identification: "A client describes a shadow in vision. Which condition should the nurse suspect?" (Answer: Retinal detachment).
  • Post-Operative Care: "Following pneumatic retinopexy, the nurse should instruct the client to maintain which position?" (Answer: As prescribed, often a specific head position to keep the gas bubble in place).
  • Patient Education: "Which instruction is most important for a client at risk for retinal detachment?" (Answer: Report new floaters/flashes/shadow immediately).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in an urgent care clinic. Mr. Johnson, 65, walks in stating, "About an hour ago, I saw bright flashes in my right eye, and now it's like a dark curtain is coming down from the top. I can't see to the side." He denies pain. His medical history includes severe myopia (nearsightedness).

Nursing Intervention Strategy:
  1. Immediate Assessment & Action:
    • Remain calm. Have the client sit or lie down immediately.
    • Position: Assist him into a semi-Fowler's position. Then, gently guide him to lie on his left side (unaffected eye down, right/affected eye up). Explain: "This position uses gravity to help keep everything in place while we get you help."
    • Limit Activity: Instruct him to avoid moving his eyes or head suddenly. No reading, TV, or phone use.
  2. Communication & Coordination:
    • Notify the physician/provider STAT and relay the classic symptoms.
    • Prepare for immediate transfer to an emergency department with ophthalmology coverage or direct to an ophthalmologist's office if protocol allows.
    • Document precisely: "Client reports sudden onset of flashing lights and 'curtain-like' shadow in peripheral vision of right eye. Denies pain. Positioned semi-Fowler's, turned to left lateral side. Ophthalmology notified."
  3. Patient Education & Support:
    • While arranging care, provide clear, simple explanations. "We think part of the lining at the back of your eye may be coming loose. This is serious, but treatable. The most important thing right now is to keep still and in this position."
    • Address anxiety. Acknowledge the fear of vision loss.
Patient Safety and Precautions:
  • Do NOT apply pressure to the eye, patch it without specific orders, or administer any eye drops unless specifically ordered for this condition.
  • Do NOT allow the client to bend over, strain, or lift anything.
  • If transport is needed, maintain the positioning as best as possible (e.g., sitting upright in a wheelchair, head supported).

Nursing Procedure & Medication Flow Procedure: Managing a Suspected Retinal Detachment 1. Recognize the classic symptom triad (Floaters, Flashes, Field loss). 2. Act: Immediately position client (Head elevated, affected eye superior/dependent based on location of detachment – general rule is affected eye down). 3. Restrict: Enforce bed/chair rest with bathroom privileges only. No Valsalva maneuvers. 4. Refer: Activate emergency ophthalmology consult protocol. 5. Prepare: Assist with urgent transfer if needed.
Medication Note: In the acute pre-op phase, medications are rarely given by the nurse. Post-operatively, expect medications like:
  • Cycloplegics (e.g., Atropine): To paralyze accommodation and rest the eye.
  • Topical Antibiotics/Steroids: To prevent infection and reduce inflammation.
  • Analgesics: For post-operative discomfort.

A Word from Your Senior Nurse "Eyesight is precious. When a patient describes that 'curtain' sensation, time is vision. Your quick thinking and simple action of proper positioning can literally help save their sight. In clinical practice, you might be the first to hear this complaint in a med-surg unit, a clinic, or even over the phone. Don't downplay it. 'Painless' doesn't mean 'not urgent.' Your knowledge and calm, decisive intervention in those first minutes make you a vital advocate. On the NCLEX, they're testing if you understand the 'why' behind the action – and in real life, that 'why' is your patient's future ability to see their grandchildren's faces."
