A nurse is assessing a patient who sustained a blunt trauma to the left eye 2 hours ago. Which assessment finding would be most concerning and require immediate intervention?
1Mild periorbital swelling and tenderness
2Severe eye pain with nausea and vomiting✓ 정답
3Small subconjunctival hemorrhage
4Slight decrease in visual acuity
해설
Severe eye pain with nausea and vomiting after blunt trauma indicates increased intraocular pressure or serious complications like hyphema or retinal detachment, requiring immediate intervention. Other findings like mild swelling or small hemorrhage are less urgent and manageable with standard care.
Core Nursing ExplanationKey Concept Analysis: This question assesses the ability to recognize a sight-threatening emergency following ocular trauma. The core theme is identifying signs of acute angle-closure glaucoma or retrobulbar hemorrhage, both of which cause a rapid, dangerous rise in intraocular pressure (IOP). Blunt trauma can trigger these conditions by causing bleeding or inflammation that blocks the eye's drainage system.
Answer Rationale: Key Point! The combination of severe eye pain with nausea and vomiting is a classic, red-flag presentation for acutely elevated IOP. The pain is often described as deep, throbbing, or "the worst headache of my life" around the eye. The nausea and vomiting are autonomic nervous system responses to the severe pain and pressure, not due to a gastrointestinal issue. This triad (severe pain, nausea/vomiting, history of trauma) mandates immediate intervention to prevent permanent optic nerve damage and vision loss.
Distractor Analysis:
Watch out for confusion! Option ①, "Mild periorbital swelling and tenderness," is an expected finding after blunt trauma and does not in itself indicate an emergency. It requires monitoring and supportive care (ice).
Option ③, "Small subconjunctival hemorrhage," while dramatic in appearance, is typically benign. It's a broken blood vessel under the clear conjunctiva and resolves on its own, posing no immediate threat to vision.
Option ④, "Slight decrease in visual acuity," is concerning and requires evaluation, but it is not as immediately life- or sight-threatening as the autonomic symptoms in option ②. A slight decrease could be due to corneal edema or a small hyphema, which are urgent but the presence of severe pain with nausea elevates the priority.
Related Concepts: This scenario tests triage and prioritization. In nursing, symptoms indicating increased intracranial pressure (ICP) (headache, vomiting, altered consciousness) are high-priority. Similarly, symptoms indicating increased intraocular pressure (IOP) (severe pain, nausea/vomiting, vision loss) are also high-priority ocular emergencies. The mechanism linking trauma to nausea/vomiting is a vagal response.
Concept Summary
- Emergency Sign: Severe eye pain + Nausea/Vomiting = Suspect acute angle-closure glaucoma or retrobulbar hemorrhage.
- Pathophysiology: Trauma → Inflammation/Bleeding → Blocked aqueous humor drainage (trabecular meshwork) → Rapid ↑ IOP → Optic nerve compression.
- Nursing Priority: Immediate notification of provider, prepare for interventions to lower IOP (e.g., IV mannitol, topical beta-blockers, carbonic anhydrase inhibitors).
- Expected vs. Concerning Findings: Swelling and subconjunctival hemorrhage are common; vision changes are urgent; pain with autonomic symptoms is critical.

Anatomy, Physiology & Pharmacology Points
- Anatomy: The anterior chamber is the space between the cornea and iris filled with aqueous humor. It drains via the trabecular meshwork into the canal of Schlemm.
- Physiology: Normal IOP is 10-21 mmHg. A rapid rise above this can cause optic nerve ischemia.
- Pharmacology (Emergency): First-line drugs to rapidly lower IOP include osmotic diuretics (IV Mannitol) to pull fluid from the eye, topical beta-blockers (Timolol) to reduce aqueous production, and carbonic anhydrase inhibitors (Acetazolamide).
Memory Tips
- Mnemonic for Acute Angle-Closure Glaucoma Symptoms: "Pain, Redness, Optic nerve changes (vision loss), Pupil mid-dilated/unreactive, IOP high, Nausea/Vomiting" = PROPIN.
- Think: "Pain + Puke = Pressure Problem." Autonomic symptoms (nausea/vomiting) with eye pain are never normal.
High-Frequency NCLEX Topics
This is a classic NCLEX priority-setting and "which finding is most concerning?" question. The NCLEX loves to test your ability to distinguish between expected post-injury findings and signs of a true emergency. Remember, symptoms affecting the ABCs (Airway, Breathing, Circulation) or a major sense organ (vision) with signs of acute distress (severe pain, autonomic response) are almost always top priority.
Watch Out for Question Variations!
- Instead of asking for the "most concerning finding," the question could ask: "The nurse should prepare for which immediate intervention?" (Answer: Administer prescribed osmotic diuretic like mannitol).
- Or: "Which nursing diagnosis takes priority?" (Answer: Risk for injury related to potential permanent vision impairment).
- The scenario could shift to a post-operative patient after eye surgery (e.g., cataract) presenting with the same symptoms, testing the same concept of acute IOP rise.
Nursing Clinical Practice GuideClinical Scenario: You are a nurse in the Emergency Department. Mr. Johnson, 58, presents after being hit in the left eye with a tennis ball 2 hours ago. He is holding his head, moaning, and says, "My eye is killing me, and I feel like I'm going to throw up."
Nursing Intervention Strategy:
1Immediate Assessment & ActionDo NOT delay. This is a "see one, do one, tell one" situation. While staying with the patient, use the call light to alert the charge nurse or provider immediately. Your verbal report should be: "Room 4, blunt eye trauma, severe pain with nausea, suspect acute IOP elevation."
2Focused AssessmentWhile awaiting orders, quickly but gently assess:
VisionAsk "Can you see my fingers?" Check each eye separately. Do NOT put pressure on the globe.
InspectionLook for corneal cloudiness, a fixed mid-dilated pupil, and obvious blood in the anterior chamber (hyphema).
Vital SignsObtain BP, HR. Pain and anxiety will elevate them.
3Patient Safety and Precautions
DO NOTapply a patch or any pressure to the eye.
DO NOTgive anything by mouth (NPO) in case procedural sedation or surgery is needed.
DOkeep the head of bed elevated to promote venous drainage and slightly lower IOP.
- Keep the room dimly lit if the patient is photophobic.
4Preparation for TreatmentAnticipate and prepare for:
- IV access for medications (mannitol, antiemetics, analgesics).
- Topical eye drops (timolol, pilocarpine, apraclonidine).
- Preparation for a procedural intervention like paracentesis (needle drainage of aqueous humor) or surgery.
Nursing Procedure & Medication Flow
1IV Mannitol AdministrationThis is a high-alert medication.
2IndicationRapid reduction of IOP.
3DoseTypically 1-2 g/kg of 20% solution IV over 30-60 minutes.
4Nursing ActionsUse a filter needle to draw up. Use a large-bore IV. Monitor for fluid overload (crackles, dyspnea) and electrolyte imbalance (especially potassium). Insert Foley catheter as ordered—mannitol is a potent osmotic diuretic.
5Patient EducationExplain it will cause intense urination to "shrink the pressure in the eye."
A Word from Your Senior Nurse
"Trust your gut! When a patient with an eye injury has pain so bad it makes them nauseous, it's not 'just a black eye.' You are the first line of defense for saving their vision. In clinicals and on the NCLEX, always think pathophysiologically: What is the worst possible complication of this injury? For blunt eye trauma, it's a spike in pressure that can crush the optic nerve in hours. Your rapid recognition and escalation of care make all the difference. Remember, in nursing, we treat the patient's response to the illness or injury. Here, the severe pain and nausea are the emergency. Act on them!"
Intraocular Pressure — The fluid pressure inside the eye. Normal range is 10-21 mmHg. Acutely elevated IOP is a sight-threatening emergency.
Acute Angle-Closure Glaucoma — A sudden, painful increase in IOP due to blockage of the eye's drainage angle by the iris. Symptoms include severe eye pain, headache, nausea/vomiting, halos around lights, and blurred vision.
Hyphema — Blood in the anterior chamber of the eye, often caused by blunt trauma. It appears as a visible layer of blood behind the cornea and can increase IOP.
Retrobulbar Hemorrhage — Bleeding behind the eyeball within the orbit. It can cause a compartment syndrome-like effect, rapidly increasing IOP and compromising blood flow to the optic nerve.
Osmotic Diuretic — A first-line IV medication for acutely elevated IOP. It draws fluid from the eye into the bloodstream by creating an osmotic gradient, rapidly lowering pressure.
