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 most important initial nursing assessment for this client?

The priority assessment is to evaluate for signs of increased intraocular pressure and globe rupture, which are sight-threatening emergencies. Other assessments like visual acuity or object examination are secondary and may worsen injury.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing assessment for a patient with a penetrating eye injury. The core principle is patient safety and preventing further harm. A metal fragment embedded in the eye is a Key Point! open globe injury, which carries a high risk for globe rupture and extrusion of intraocular contents. The most immediate threat is a sudden increase in intraocular pressure (IOP), which can be caused by the patient squeezing the eyelid, coughing, vomiting, or any manipulation of the eye. This pressure can force ocular contents out through the wound, leading to permanent, irreversible vision loss.

Answer Rationale: Key Point! The correct answer is ③ Assess for signs of increased intraocular pressure and globe rupture. This is the priority because it identifies life-altering, sight-threatening complications that require immediate intervention to preserve vision. Signs of increased IOP or globe rupture include severe pain, a teardrop-shaped pupil (indicating iris prolapse), a shallow or flat anterior chamber, visible uveal tissue (dark material) at the wound site, or a sudden decrease in vision. This assessment guides the nurse to take immediate protective actions, such as placing a protective shield (not a patch) over the eye and preventing any activities that increase IOP.

Distractor Analysis:
Watch out for confusion! ① Assess visual acuity: While important for baseline data, forcing the patient to read a Snellen chart requires them to open and focus the injured eye, which can increase IOP and potentially worsen the injury. This should be deferred until the eye is stabilized.
Watch out for confusion! ② Examine the depth/location of the object: Never attempt to remove or manipulate an embedded foreign object. Direct visualization or probing can cause the object to move, lacerate internal structures, or increase pressure, leading to further damage. This is the physician's role, often in an operating room setting.
Watch out for confusion! ④ Evaluate eye movement (Extraocular movements, EOMs): Asking the patient to move the eye in all directions can strain the extraocular muscles and increase pressure within the globe, potentially exacerbating the injury. Assessment of EOMs is contraindicated in suspected open globe injuries.

Related Concepts: The nursing priority follows the ABCs (Airway, Breathing, Circulation) with a sensory organ twist: Protect the Eye (PE). Initial management includes placing a rigid eye shield (not applying pressure), keeping the patient NPO (nothing by mouth) in case surgery is needed, administering antiemetics to prevent vomiting, elevating the head of bed, and providing reassurance to keep the patient calm. All interventions aim to minimize IOP. Concept Summary

Concept	Description	Nursing Implication
Open Globe Injury	Full-thickness wound of the cornea or sclera. High risk for infection (endophthalmitis) and vision loss.	Do NOT patch. Apply a rigid eye shield. Administer IV antibiotics as ordered.
Increased Intraocular Pressure (IOP)	Pressure inside the eye > 10-21 mmHg. Sudden spikes can extrude ocular contents.	Prevent coughing, vomiting, straining, bending. Keep patient calm and upright.
Globe Rupture	Loss of structural integrity of the eye wall. A sight-threatening emergency.	Signs: Peaked pupil, uveal prolapse, profound vision loss. Requires immediate surgical repair.
Priority Assessment	In trauma, always assess for threats to life or limb (vision) first.	Assess for complications (rupture, high IOP) before performing functional tests (acuity, movement).

Side-by-Side Comparison!

Assessment/Intervention	Penetrating Injury (Open Globe)	Superficial Foreign Body (Corneal Abrasion)
Priority Action	Protect eye, prevent IOP increase, prepare for surgery.	Remove particle, irrigate eye, assess for abrasion.
Eye Covering	Rigid eye shield (e.g., Fox shield). No pressure on globe.	May patch the eye to promote healing and reduce pain from blinking.
Visual Acuity Check	Contraindicated initially if it risks worsening injury.	Perform as part of initial assessment.
Eye Movement Check	Avoid. Can increase IOP.	Assess to rule out deeper injury.

Anatomy, Physiology & Pharmacology Points

• Anatomy: The eye is a closed, pressurized system. The cornea and sclera form its outer wall. A break in this wall compromises the integrity of the entire system.
• Physiology: Aqueous humor is continuously produced and drained to maintain IOP. An open wound disrupts this balance, allowing contents to escape and increasing risk of infection from the outside environment.
• Pharmacology: Common medications include systemic antibiotics (e.g., vancomycin + ceftazidime) for infection prophylaxis, antiemetics (e.g., ondansetron) to prevent vomiting, analgesics, and tetanus prophylaxis.

Memory Tips

• Acronym: SHIELD for Penetrating Eye Injury Priority:
  Stabilize & Shield (rigid shield).
  Halt increased IOP (prevent straining).
  Inspect for rupture signs (peaked pupil).
  Elevate HOB.
  Limit movement/NPO.
  Do NOT remove object/check acuity/move eye.
• Think: "Don't make it POP!" Any action that increases Pressure can cause Ocular contents to Prolapse.

High-Frequency NCLEX Topics The NCLEX frequently tests priority-setting and safety in emergency scenarios. Eye injuries are a classic example where the intuitive action (check vision, look at the object) is the wrong and dangerous action. The exam wants you to recognize the greatest immediate threat to function (permanent vision loss from rupture) and act to mitigate that threat first. Watch Out for Question Variations!

• Instead of "initial assessment," the question may ask for the "priority nursing action" – the answer would be "Place a protective eye shield over the affected eye."
• The scenario could change to a chemical burn. The priority then becomes immediate and prolonged irrigation with normal saline, which takes precedence over all other assessments.
• It may ask which order by the physician the nurse should question or implement first. An order for "check visual acuity" or "remove the embedded fragment" should be questioned.

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the ED. A 32-year-old construction worker is brought in by coworkers. He is holding a cloth over his right eye, reporting "something metal flew into my eye" about 30 minutes ago. He is anxious, in moderate pain, and nauseated.

Nursing Intervention Strategy:

1. Immediate Assessment & Safety: Quickly introduce yourself. Do not remove the cloth. Ask the patient to keep both eyes still. In a calm manner, assess for obvious signs of globe rupture: Is the pupil shape normal? Is there dark tissue (uvea) visible? Is there significant swelling or deformity? Ask about a sudden "gush" of fluid or profound vision loss.
2. Priority Action: Apply a rigid eye shield. Gently place it over the injured eye, securing it with tape to the bony orbits of the forehead and cheek. Ensure no pressure is placed on the eyeball itself. Instruct the patient not to rub or touch the eye.
3. Comprehensive Care: Keep the patient sitting upright or with HOB elevated to reduce venous pressure and IOP. Establish IV access. Administer prescribed antiemetics, analgesics, and antibiotics. Keep the patient NPO. Place a "Nothing by Mouth" sign and explain the potential for immediate surgery. Document the mechanism of injury, time of injury, and all assessments thoroughly.

Patient Safety and Precautions:

• Contraindication: Never use an eye patch (which applies pressure) on a suspected open globe. Never attempt to irrigate an eye with a penetrating object.
• Medication Caution: Avoid medications that can cause nausea or vomiting. Use sedatives cautiously only if needed for extreme agitation, as they can mask neurological symptoms if a concurrent head injury is suspected.
• Key Monitoring: Monitor for increased pain (indicating rising IOP), increased nausea/vomiting, and changes in the appearance of the eye or vision.

Nursing Procedure & Medication Flow Procedure: Applying a Protective Eye Shield 1. Explain the procedure to the patient: "I'm going to place a hard shield over your eye to protect it. It won't touch your eye." 2. Wash hands and don gloves. 3. Have the patient look straight ahead with the uninjured eye. 4. Gently place the concave side of the rigid shield over the injured eye. 5. Secure the shield with tape to the brow and cheekbone. Ensure it is stable but not tight. 6. Document: "Rigid eye shield applied to right eye. Patient instructed to avoid eye movement and rubbing."

Medication: Tetanus Prophylaxis - A penetrating injury with a metal object is a tetanus-prone wound. - If the patient's immunization status is unknown or the last booster was >5 years ago, administer Tetanus Toxoid as ordered. - Administer via IM injection in the deltoid or vastus lateralis. A Word from Your Senior Nurse "In the chaos of the ED, a patient with an eye injury can be terrifying for them—they're facing the real possibility of blindness. Your calm, confident, and knowledgeable actions are their first line of defense. Remember, your hands can do harm if you act on the instinct to 'look and see.' Your priority is to be a protector. Shield the eye, shield the patient from actions that increase pressure, and be their advocate for immediate specialist care. This mindset of 'first, do no harm' and acting on pathophysiological principles is exactly what the NCLEX tests and what makes an excellent nurse."
