A nurse is caring for a client who sustained a blunt trauma to the eye resulting in an eye contusion. Which nursing intervention should the nurse implement first?

2Instill prescribed antibiotic eye drops immediately to prevent infection
3Encourage the client to keep both eyes open to prevent muscle spasms
4Apply warm compresses to reduce swelling and promote circulation
해설
Cold compresses are the priority to reduce swelling, bleeding, and pain in the acute phase of eye contusion. Other interventions like antibiotics, keeping eyes open, or warm compresses are not immediate priorities.
A blunt trauma to the eye, often called a contusion or “black eye,” occurs when a direct blow to the periorbital area causes soft tissue damage and capillary rupture. This leads to immediate edema and the characteristic ecchymosis (bruising). The primary pathophysiological response is acute inflammation, which increases blood flow and vascular permeability at the injury site. The initial treatment goal is not to prevent infection or exercise the muscles, but to manage this acute inflammatory response by limiting swelling and controlling pain. The provided literature on ocular injuries confirms that blunt trauma is a common mechanism, and effective initial management focuses on minimizing secondary tissue damage from uncontrolled edema.
Prioritizing the First Intervention
The NCLEX-RN requires you to prioritize care based on the most immediate physiological need. For a new eye contusion, the first and most critical step is applying cold compresses. The cold causes local vasoconstriction, which reduces blood flow to the injured capillaries. This mechanism directly limits the accumulation of fluid (edema) and blood (ecchymosis) in the soft tissues, thereby minimizing pain and the extent of the bruise. The standard protocol is to apply the cold compress for 15-20 minutes every hour during the first 24-48 hours post-injury. This timing is crucial because it targets the peak period of the body’s inflammatory response.
Why Other Options Are Not the First Priority
Option 2 (Instill antibiotic drops): A contusion from blunt trauma is a closed injury; there is no break in the skin or globe rupture indicated in the scenario. Antibiotic eye drops are indicated for open injuries, corneal abrasions, or penetrating trauma to prevent infection, not for a closed contusion. Using them without an open wound is not an immediate priority and can be an unnecessary intervention.
Option 3 (Keep both eyes open): This instruction is incorrect and potentially harmful. Keeping the eyes open forces the extraocular muscles to move, which can increase pain and intraocular pressure in an already traumatized eye. The standard of care is to advise the client to rest the eyes and limit movement, often by keeping them closed, to promote comfort and healing.
Option 4 (Apply warm compresses): Warm compresses promote vasodilation, which increases blood flow and can worsen swelling and bruising in the acute phase. This intervention is contraindicated in the first 24-48 hours. It becomes appropriate only after the acute swelling has subsided to help reabsorb the trapped blood and fluid.
The initial application of cold compresses directly addresses the acute inflammatory process triggered by the blunt trauma, making it the correct and highest-priority nursing intervention.
Clinical Scenario
A 32-year-old male presents to the emergency department 30 minutes after being struck in the right eye with a baseball. Examination reveals significant periorbital edema and ecchymosis. Visual acuity is 20/20 bilaterally, pupils are equal and reactive, and extraocular movements are intact. No corneal abrasion or open wound is identified. The client reports pain rated 6/10.
Nursing Actions
Immediately apply a cold compress or ice pack wrapped in a cloth to the affected eye for 15-20 minutes.
Reapply the cold compress every hour during the first 24-48 hours to manage the acute inflammatory response.
Administer prescribed oral analgesics for pain control as needed.
Elevate the head of the bed to 30 degrees to facilitate venous drainage and reduce edema.
Instruct the client to avoid blowing the nose or straining, which can increase intraocular pressure.
Clinical Rationale
Cold application is the priority intervention because it induces local vasoconstriction, directly counteracting the vasodilation and increased capillary permeability of the acute inflammatory phase. This limits the accumulation of fluid and blood in the periorbital tissues, minimizing secondary tissue damage, pain, and the extent of ecchymosis. The 24-48 hour window is critical as this is when the inflammatory response peaks. Warm compresses are contraindicated during this period as heat promotes vasodilation and would worsen swelling.
Follow-Up Care
After 48 hours, transition to warm compresses to promote reabsorption of the ecchymosis.
Monitor for signs of more serious injury, such as decreased visual acuity, diplopia, severe eye pain, or hyphema (blood in the anterior chamber).
Reinforce the importance of follow-up with an ophthalmologist if symptoms do not improve or worsen.
Eye Contusion — Eyeball contusion. Bruising and swelling caused by blunt force trauma to the eye or surrounding tissues. Characterized by subconjunctival hemorrhage, swelling of surrounding tissues, and pain.
Cold Compress / Cryotherapy — Cold compress/cold therapy. A treatment that induces vasoconstriction to reduce swelling, bleeding, inflammation, and pain. Applied during the first 24-48 hours after acute trauma.
Periorbital Ecchymosis — Periorbital hematoma. "Raccoon eyes" caused by subcutaneous bleeding in the tissues around the eyes. This can also appear with a skull base fracture, so it requires careful evaluation.
Intraocular Pressure — Intraocular pressure. The pressure inside the eyeball. After ocular trauma, intraocular pressure can rise (exceeding the normal 10-21 mmHg), which is dangerous as it can lead to acute glaucoma.
Hyphema — Hyphema. Blood pooling in the anterior chamber between the cornea and iris. A serious complication of blunt eye trauma, requiring immediate ophthalmologist care.
