A nurse is caring for a client who presents to the emergency department with a metal fragment embedded in the right eye following a workplace accident. What is the nurse's priority action?

The priority is to stabilize the embedded object and cover both eyes to prevent further damage from movement. Removing the object or applying pressure can cause additional injury.

Core Principle in Ocular Trauma with Penetrating Foreign Body

When a penetrating object is embedded in the eye, the immediate priority is to prevent further injury. Any manipulation, including removal, irrigation, or application of pressure, can cause catastrophic intraocular content extrusion and permanent vision loss. The standard of care is to stabilize the object in place and protect the eye from external pressure or movement.





Why Stabilizing and Shielding Both Eyes Is Correct

In an open globe injury, which is strongly suggested by a metal fragment embedded in the eye, the structural integrity of the globe is compromised. The Guidelines for Essential Trauma Care emphasize that initial management of such injuries must focus on preventing secondary injury during transport and assessment . Covering both eyes with a rigid protective shield (not a pressure patch) serves two critical purposes:



  • Immobilization: The unaffected eye moves consensually with the injured eye (oculocephalic reflex). By covering both eyes, you minimize sympathetic eye movement, which reduces traction on the embedded object and prevents further tearing of the globe.

  • Protection from external pressure: A rigid shield placed over the object and the eye prevents accidental bumping, rubbing, or pressure that could expel intraocular contents.


Research on open globe injuries in industrial regions highlights that the initial management and timely, appropriate surgical repair are key prognostic factors for final visual acuity . The nurse's role at the point of presentation is to preserve the existing structures for surgical repair, not to attempt definitive treatment.





Why the Other Options Are Harmful

Option 1: Remove the metal fragment immediately to prevent further damage.


Removing a penetrating object from the eye in the emergency department is strictly contraindicated. The object may be plugging a wound; removing it can unseal the injury, leading to sudden decompression of the globe and extrusion of the iris, lens, or vitreous humor. This is a surgical procedure performed under an operating microscope. The systematic review on AI in ocular trauma underscores that prompt and accurate diagnosis is vital, but definitive management is surgical .




Option 2: Irrigate the eye with normal saline to flush out debris.


Irrigation is indicated for chemical burns or superficial foreign bodies, not for a penetrating injury. Flushing an open globe can introduce fluid into the intraocular space, increase intraocular pressure, and force the foreign body deeper, causing additional damage and introducing infection.




Option 3: Apply direct pressure to the eye to control bleeding.


Applying direct pressure to an eye with a suspected open globe injury is extremely dangerous. Pressure on the anterior chamber can cause the intraocular contents to herniate through the wound, resulting in irreversible blindness. Bleeding from the eye itself is managed with gentle, sterile dressing if needed, but never with direct pressure on the globe.






Clinical Application and Psychosocial Context

Ocular trauma is a leading cause of acquired monocular blindness in working-age adults and carries a significant psychosocial burden, including anxiety and reduced vision-related quality of life . The nurse's initial actions directly impact the patient's long-term functional outcome. By correctly stabilizing the injury and preventing further harm, the nurse helps preserve the possibility of optimal surgical repair and visual rehabilitation. The assessment should include the mechanism of injury (workplace accident with a metal fragment), visual acuity in the unaffected eye, and a history of the event, but the priority action remains the physical stabilization of the injury with a shield over both eyes, followed by urgent ophthalmology consultation and keeping the patient NPO in anticipation of surgical repair.

Open Globe Injury: Initial ManagementStabilize, Shield, and Shield the Other Eye

For any suspected open globe injury (penetrating object, laceration, rupture), the immediate priority is to stabilize the object in place and prevent secondary injury. Do not attempt removal, irrigation, or apply any pressure.

Cover the injured eye with a rigid protective shield (e.g., Fox shield, paper cup). Avoid using a pressure patch. Then, cover the unaffected eye as well to minimize consensual movement via the oculocephalic reflex, which reduces traction on the embedded object.

Caution

Never remove a penetrating object, irrigate the eye, or apply direct pressure. These actions risk catastrophic intraocular content extrusion and permanent vision loss. Keep the patient NPO and elevate the head of bed to 30 degrees if no spinal injury is suspected.
