해설
Changes in intraocular pressure are critical as increased pressure can lead to permanent vision loss. Other findings like conjunctival redness, eyelid swelling, or tearing are less urgent.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing assessment for a patient with a blunt eye contusion. The core concern is preventing permanent vision loss by identifying and managing a potential hyphema (blood in the anterior chamber of the eye) or other injury that can cause a rapid, dangerous rise in intraocular pressure (IOP). Blunt trauma can damage the eye's internal structures, leading to bleeding or disruption of the aqueous humor drainage system, which in turn elevates IOP. Elevated IOP can compress the optic nerve, leading to irreversible damage and vision loss.
Answer Rationale: Key Point!Changes in intraocular pressure are the most important immediate assessment because they are a direct indicator of potentially sight-threatening complications like hyphema, traumatic iritis, or angle-recession glaucoma. Monitoring IOP allows for early intervention (e.g., medications to lower pressure) to preserve vision. While the other findings are present and should be documented, they do not carry the same immediate risk of permanent blindness.
Distractor Analysis:
Watch out for confusion!Presence of conjunctival redness (Option 1) is a common finding after trauma (subconjunctival hemorrhage) but is often superficial and not an immediate threat to vision.
Degree of eyelid swelling (Option 3) can be significant and alarming to the patient, but it is an external finding. While it needs management (ice packs), it does not directly indicate internal ocular damage affecting pressure or vision.
Amount of tearing from the eye (Option 4) is a normal reflexive response to pain and irritation. It is not a reliable indicator of the severity of internal injury.
Related Concepts: The nursing priority follows the ABCs with a sensory focus. In eye emergencies, preserving vision is paramount. Key complications of blunt trauma include hyphema, retinal detachment, and ruptured globe. Immediate interventions include elevating the head of bed, applying a protective shield (not a patch), and avoiding activities that increase IOP (bending, straining, vomiting).
Concept Summary
• Blunt Eye Trauma: Injury caused by a direct force (e.g., ball, fist) without penetrating the eye.
• Primary Threat: Elevated Intraocular Pressure (IOP) leading to optic nerve damage.
• Key Complication: Hyphema (blood in anterior chamber).
• Nursing Priority: Monitor for signs of rising IOP (severe pain, nausea, vomiting, vision changes, cloudy cornea) and implement measures to reduce it.
• Immediate Action: Elevate HOB 30-45 degrees, apply eye shield, administer prescribed IOP-lowering medications (e.g., topical beta-blockers).

Priority Level
Changes in Intraocular Pressure (IOP)
Direct indicator of internal damage (hyphema, angle injury). Risk of permanent vision loss.
Key Point! HIGHEST PRIORITY
Conjunctival Redness/Subconjunctival Hemorrhage
Superficial bleeding under conjunctiva. Looks dramatic but is usually benign and self-limiting.
Low Priority
Eyelid Swelling (Periorbital Ecchymosis)
External soft tissue injury. Manage with cold compresses.
Moderate Priority (for comfort)
Tearing (Epiphora)
Reflex response to irritation or pain. Not diagnostic.
Low Priority
Anatomy, Physiology & Pharmacology Points
• Anatomy: The anterior chamber is the space between the cornea and iris. Blood collecting here is a hyphema.
• Physiology: Aqueous humor is produced by the ciliary body and drains through the trabecular meshwork. Trauma can block drainage, raising IOP. Normal IOP is 10-21 mmHg.
• Pharmacology: Emergency drugs to lower IOP include timolol (beta-blocker), acetazolamide (carbonic anhydrase inhibitor), and mannitol (osmotic diuretic).
Memory Tips
• Acronym: EYE PRIORITY: Evaluate Your patient's Intraocular Pressure Rapidly; It Threatens Vision.
• Association: Think of the eye as a closed, pressurized system (like a balloon). A blow can damage the "valve" (drainage angle), causing pressure to build up and "pop" the optic nerve.
• NCLEX Cue: When an eye question involves trauma and "most important" or "priority," immediately think intraocular pressure or vision assessment.
High-Frequency NCLEX Topics
This is a classic Core priority-setting question. NCLEX frequently tests:
1. Identifying the most urgent assessment among several plausible options.
2. Knowledge of complications specific to body systems (here, ocular trauma).
3. Differentiating between alarming-looking but benign symptoms vs. subtle but dangerous signs.
Watch Out for Question Variations!
• From Assessment to Intervention: "The nurse notes the client's intraocular pressure is 28 mmHg. Which intervention should the nurse implement first?" (Answer: Administer prescribed IOP-lowering eyedrops).
• Patient Education Focus: "Which instruction is most important for a client with a hyphema?" (Answer: Maintain head elevation and avoid straining/bending).
• Complication Identification: "Which finding suggests a complication of a blunt eye injury?" (Answer: Sudden increase in pain accompanied by nausea).
Nursing Clinical Practice GuideClinical Scenario: You are the triage nurse in the ED. A 30-year-old male arrives holding a towel over his left eye after being hit by a hockey puck. He rates his pain as 8/10 and says his vision is "foggy."
Nursing Intervention Strategy:
1Immediate Assessment & SafetyQuickly assess visual acuity in the unaffected eye first, then the injured eye if possible. Do not put pressure on the eye. Inquire about mechanism of injury and any loss of consciousness (rule out concurrent head injury).
2Priority MonitoringCollaborate with the provider for an immediate IOP check via tonometry. Document baseline IOP and monitor for trends. Assess for signs of rising IOP: severe headache, nausea/vomiting, seeing halos around lights.
3Comfort & ProtectionApply a rigid eye shield (not a patch, which could exert pressure). Initiate ordered pain management. Apply cold compresses to the periorbital area (eyelids) to reduce swelling, being careful not to press on the globe itself.
4Patient Education & PreparationEducate on the importance of head elevation (HOB at 30-45 degrees even during sleep). Instruct to avoid activities that increase IOP: bending over, straining during bowel movements, vomiting (anti-emetics may be given), coughing forcefully, or lifting heavy objects.
Patient Safety and Precautions:
• Contraindication: Never apply a pressure patch to a suspected blunt injury or hyphema, as it can trap blood and increase IOP.
• Medication Caution: If acetazolamide is prescribed, monitor for side effects like tingling in extremities, metallic taste, and potential electrolyte imbalance.
• Key Monitoring: Serial IOP measurements, visual acuity checks, and inspection of the eye for increased cloudiness or a re-bleed (which may appear as a fresh red layer over old blood).
Nursing Procedure & Medication FlowProcedure: Assisting with Tonometry (IOP Measurement)
1. Explain the procedure to the client.
2. Instill ordered topical anesthetic drops (e.g., proparacaine).
3. The provider or trained nurse will gently touch the cornea with the tonometer probe.
4. Document the IOP reading immediately. A reading >21 mmHg is abnormal and requires intervention.
5. Observe for corneal abrasion post-procedure (client may report scratchy feeling).Medication: Administering Timolol Eyedrops
1. Verify order and patient allergy status.
2. Wash hands. Tilt patient's head back.
3. Gently pull down lower eyelid to form a pouch.
4. Instill the prescribed number of drops into the conjunctival sac, avoiding contact with the dropper tip.
5. Apply gentle pressure to the nasolacrimal duct (inner corner of eye) for 1-2 minutes to minimize systemic absorption and potential beta-blocker side effects (bradycardia, bronchospasm).
A Word from Your Senior Nurse
"Eye injuries can be incredibly scary for patients. They're not just in pain—they're terrified of losing their sight. Your calm, knowledgeable assessment is their first line of defense. Remember, you're not just looking at the eye, you're thinking about what's happening inside it. That swollen eyelid might get all the attention, but it's the silent rise in pressure behind it that's the real enemy. In the ED and on the NCLEX, always ask yourself: 'What is the threat to life or permanent function?' For eye trauma, the answer is almost always vision, and the pathway to that threat is intraocular pressure. Master that connection, and you'll provide excellent care and ace these questions!"
Intraocular Pressure — The fluid pressure inside the eye. Normal range is 10-21 mmHg. Elevated IOP is a medical emergency in trauma as it can damage the optic nerve.
Hyphema — Accumulation of blood in the anterior chamber of the eye, a common complication of blunt trauma that can obstruct aqueous humor drainage and raise IOP.
Blunt Eye Contusion — A closed-globe injury caused by a direct, non-penetrating force to the eye, resulting in damage to internal structures without a full-thickness wound.
Tonometry — The clinical procedure for measuring intraocular pressure. Essential for monitoring patients after ocular trauma.
Nasolacrimal Duct Pressure — Applying gentle pressure to the inner corner of the eye after administering certain eyedrops to slow systemic absorption and reduce systemic side effects.
