Which nursing action should be the priority? ## 보기 1. Cover both eyes with sterile gauze pads and keep the client in a supine position **✔ 정답** 2. Irrigate the affected eye immediately with normal saline solution 3. Apply topical anesthetic drops to reduce pain and discomfort 4. Attempt to remove the foreign body using sterile cotton swabs **정답: 1** ## 해설 Covering both eyes with sterile gauze pads and keeping the client supine prevents sympathetic eye movement and further injury from the metallic foreign body. Other options like irrigation or removal can worsen the injury and should be avoided until ophthalmologic evaluation. ## 심화 해설 Understanding the Priority The presence of a metallic foreign body in the eye constitutes an ocular emergency. The primary goal of immediate nursing management is not removal or irrigation, but the prevention of further injury. Any movement of the affected eye, including blinking or the globe tracking an object, can cause the embedded metallic fragment to scrape across the corneal surface, turning a superficial abrasion into a deeper stromal laceration or even a full-thickness perforation. The eye's intricate structure relies on the transparency of its refractive components, particularly the cornea, making the minimization of secondary mechanical trauma the highest priority . Therefore, the nurse must immediately immobilize the globe. Why Covering Both Eyes is Critical Covering only the injured eye is insufficient because of the consensual movement of the eyes. When the uninjured eye moves, the extraocular muscles of the injured eye will instinctively move in tandem (a conjugate gaze reflex). By covering both eyes with sterile gauze pads, the nurse eliminates visual tracking stimuli, effectively paralyzing both globes. This bilateral patching is the definitive method to ensure complete ocular rest. Keeping the client in a supine position further stabilizes the head and neck, reducing postural sway that could jostle the foreign body. This approach directly addresses the time-sensitive need to prevent morbidity from a penetrating ocular injury . Analysis of Incorrect Options - **Option 2 (Irrigate the affected eye):** Irrigation is contraindicated for a metallic foreign body that may be embedded or penetrating. The force of the fluid stream can dislodge the object unpredictably, worsening the laceration, or push it deeper into the corneal stroma or anterior chamber. Irrigation is reserved for chemical burns or loose, superficial debris, not for potentially penetrating metallic fragments. - **Option 3 (Apply topical anesthetic drops):** While pain management is a consideration, applying any drops before a thorough assessment by a specialist can introduce infection, increase intraocular pressure if there is a rupture, and wash away crucial physical exam findings. More critically, this action does not address the immediate risk of ongoing mechanical injury from eye movement. - **Option 4 (Attempt to remove the foreign body):** Removal of a metallic foreign body by a nurse using a cotton swab is strictly outside the nursing scope of practice in the emergency setting. This action carries an extreme risk of causing further corneal abrasion, converting a partial-thickness injury into a full-thickness perforation, or leaving a rust ring that requires specialized ophthalmic burr removal. Definitive removal under a slit-lamp by a qualified provider is required after stabilization. Clinical Reasoning and Perioperative Implications The initial nursing action sets the trajectory for definitive care. Stabilizing the eye by bilateral patching prevents the enlargement of the epithelial defect, which directly impacts the subsequent epithelial healing time and reduces the risk of complications such as infection or scarring . In the context of traumatic eye injuries, accurate initial assessment and stabilization are paramount, as point-of-care tools like ultrasound may later be used to evaluate the extent of internal damage, but only after the globe has been protected from further harm . The nurse's priority is to protect the eye's structural integrity until an ophthalmologist can perform a definitive examination and safe removal. ## 임상 시나리오 Penetrating Ocular Foreign Body: Emergency NursingPrioritize immobilization over removal or irrigation For a metallic foreign body in the eye, the immediate priority is to prevent secondary injury from consensual eye movement. Do not irrigate, apply pressure, or attempt removal. Stabilize the object if protruding, then cover both eyes with a rigid eye shield or sterile gauze pads. This stops the conjugate gaze reflex. Keep the client supine with the head of the bed elevated 30-45 degrees. CautionNever attempt to remove an embedded object. Never irrigate the eye, as fluid can dislodge the fragment and worsen a corneal laceration. Do not patch only the affected eye. ## 핵심 개념 - **Consensual eye movement** — The involuntary, synchronized movement of both eyes in the same direction; covering one eye is insufficient to prevent movement of the injured eye. - **Ocular immobilization** — The technique of covering both eyes to stop conjugate gaze reflexes, ensuring complete rest of the injured globe to prevent secondary mechanical trauma. - **Corneal abrasion vs. laceration** — An abrasion is a superficial scrape of the corneal epithelium, while a laceration is a deeper cut into the stroma, which can be caused by a moving foreign body. ## 같은 주제 문제 - [A nurse is assessing a patient who presents to the emergency department with a suspected f…](https://mymerci.kr/pages/nclex_q.php?qn_id=541604) - [A nurse is assessing a client who presents to the emergency department with a suspected fo…](https://mymerci.kr/pages/nclex_q.php?qn_id=541605) - [A nurse is assessing a 45-year-old factory worker who presents to the emergency department…](https://mymerci.kr/pages/nclex_q.php?qn_id=541606) - [A nurse is assessing a 32-year-old mechanic who presents to the emergency department with …](https://mymerci.kr/pages/nclex_q.php?qn_id=541607) - [A client presents to the emergency department with a metallic foreign body in the right ey…](https://mymerci.kr/pages/nclex_q.php?qn_id=541608) - [A nurse is caring for a client who presents to the emergency department with a metallic fo…](https://mymerci.kr/pages/nclex_q.php?qn_id=541609) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
