A nurse is assessing a patient who sustained blunt trauma to the eye. Which finding would be most indicative of hyphema?
1Pupil dilation and photophobia
2Blood visible in the anterior chamber of the eye✓ 정답
3Increased intraocular pressure with eye pain
4Cloudy cornea with decreased visual acuity
해설
Blood visible in the anterior chamber is the most characteristic finding for hyphema, directly indicating bleeding into that space. Other findings may occur but are less specific.
Core Nursing ExplanationKey Concept Analysis: This question tests the identification of a classic physical finding for a specific ocular emergency: Hyphema. Hyphema is defined as bleeding into the Anterior chamber of the eye, which is the space between the cornea and the iris. It is a common complication following blunt trauma to the eye. The key to answering this question is recognizing the direct, pathognomonic sign of this condition.
Answer Rationale: Key Point! The most indicative, direct finding of hyphema is Blood visible in the anterior chamber. This can appear as a settled layer of red blood cells (a "layered hyphema") or as a diffuse reddish tinge to the aqueous humor. This finding is specific to hyphema and is the primary basis for diagnosis. Option 2 directly and accurately describes this pathognomonic sign.
Distractor Analysis:
Watch out for confusion! Option 1: Pupil dilation and photophobia. While these can be associated with eye trauma or inflammation (like iritis or uveitis), they are not specific to hyphema. Photophobia is more characteristic of conditions affecting the iris or corneal abrasion.
Option 3: Increased intraocular pressure with eye pain. This describes Acute angle-closure glaucoma or can be a complication of hyphema (secondary glaucoma), but it is not the primary, most indicative finding of the hyphema itself. The question asks for the finding "most indicative of hyphema," not its potential complication.
Option 4: Cloudy cornea with decreased visual acuity. A cloudy cornea is more indicative of a corneal abrasion, ulcer, or edema. Decreased visual acuity is a common symptom in many eye conditions, including hyphema, but it is a non-specific finding. The "cloudy cornea" is not characteristic of an isolated hyphema.
Related Concepts: Nursing management for a patient with hyphema focuses on preventing re-bleeding and managing intraocular pressure. Key interventions include elevating the head of the bed 30-45 degrees (to promote gravity-dependent settling of blood), applying a protective eye shield (not a pressure patch), administering prescribed medications (e.g., cycloplegics to reduce pain and ciliary spasm, topical steroids to reduce inflammation), and strict activity restrictions to avoid Valsalva maneuvers (straining, coughing, bending over) which can increase intraocular pressure and cause re-bleeding.
Concept Summary
Term
Definition & Key Points
Hyphema
Bleeding into the anterior chamber of the eye. Classic sign: visible blood. Main cause: blunt trauma.
Anterior Chamber
Space filled with aqueous humor, located between the cornea (front) and the iris/pupil (back).
Priority Nursing Care
Elevate HOB, eye shield, avoid increased IOP (no straining), monitor for re-bleed or elevated IOP.
Photophobia, deep eye ache, constricted or irregular pupil, perilimbal injection (ciliary flush)
Inflammation, autoimmune
Anatomy, Physiology & Pharmacology Points
Anatomy: The Anterior chamber is bounded anteriorly by the cornea and posteriorly by the iris and pupil. It is filled with aqueous humor, which is produced by the ciliary body and drains via the trabecular meshwork.
Pathophysiology: Blunt trauma shears blood vessels in the iris or ciliary body, causing bleeding into the aqueous humor. The blood can obstruct the trabecular meshwork, leading to Secondary glaucoma.
Pharmacology: Common medications include Cycloplegics (e.g., atropine) to paralyze the ciliary muscle, reducing pain and preventing synechiae (adhesions); Topical corticosteroids to reduce inflammation; and possibly Topical or oral IOP-lowering agents (e.g., beta-blockers, alpha-agonists, carbonic anhydrase inhibitors) if pressure rises.
Memory Tips
Hyphema = "Blood in the Front": Associate "H" with "Hemorrhage" in the front chamber.
Nursing Care: "SHE": Shield the eye. HOB elevated. Ensure rest (no Valsalva).
Complication Timing: Remember the "Rule of 5s" for re-bleeding risk: peak risk is days 3-5 post-injury.
High-Frequency NCLEX Topics
The NCLEX frequently tests the identification of classic signs for specific conditions. Hyphema is a classic trauma-related finding. Be prepared for questions that ask: "Which finding is most indicative of...?" or "The nurse identifies a complication of hyphema when..." (e.g., increased eye pain and nausea signaling elevated IOP).
Watch Out for Question Variations!
Priority Action: "The nurse's priority action for a patient with a hyphema is to..." (Answer: Apply a protective eye shield, elevate HOB).
Patient Education: "Which instruction is most important for the nurse to give a patient with hyphema?" (Answer: Avoid bending over, straining, or coughing; sleep with head elevated; report sudden increase in pain or vision loss).
Complication Recognition: "Which finding suggests a developing complication in a patient with hyphema?" (Answer: Nausea/vomiting and severe eye pain, indicating rising intraocular pressure).
Nursing Clinical Practice GuideClinical Scenario: You are a nurse in the Emergency Department. A 16-year-old male is brought in after being hit in the eye with a baseball. He complains of eye pain and says his vision is "blurry." You perform an initial assessment.
Nursing Intervention Strategy:
Assessment: Perform a focused eye assessment. Use a penlight to inspect the anterior chamber from the side. Look for a reddish tinge or a visible layer of blood. Assess visual acuity (using a Snellen chart if possible, or ask "Can you count my fingers?"). Assess for associated symptoms like headache, nausea.
Immediate Actions & Collaboration: Notify the physician/advanced practitioner immediately of suspected hyphema. Apply a rigid eye shield (not a patch) to protect the eye from further injury. Assist with tonometry to measure intraocular pressure (IOP).
Ongoing Care & Monitoring: Elevate the head of the bed to 30-45 degrees. Administer prescribed medications (e.g., cycloplegic drops, steroid drops). Provide a quiet environment. Monitor for signs of re-bleeding (sudden increase in pain, vision loss, increased blood in chamber) or elevated IOP (severe pain, nausea/vomiting, halo vision).
Patient & Family Education: Educate on strict activity restrictions: no bending, lifting, straining, coughing forcefully, or blowing nose. Sleep with head elevated on 2-3 pillows. Importance of wearing the eye shield at all times, especially while sleeping. Signs to report immediately: severe pain, nausea/vomiting, sudden vision change.
Patient Safety and Precautions:
Key Point!Never apply a pressure patch to an eye with hyphema, as it can increase intraocular pressure.
Administer antiemetics as needed to prevent vomiting, which drastically increases IOP.
For pain, avoid NSAIDs like aspirin or ibuprofen in the acute phase, as they can inhibit platelet function and increase bleeding risk. Acetaminophen is typically safer.
Nursing Procedure & Medication FlowEye Shield Application: 1) Explain procedure to patient. 2) Ensure shield is clean. 3) Gently place the concave side over the affected eye, ensuring it rests on the orbital bone. 4) Secure it with tape from forehead to cheek, avoiding pressure on the eye itself.
Medication Administration (Eye Drops): 1) Wash hands. 2) Tilt patient's head back, have them look up. 3) Gently pull lower eyelid down to form a pouch. 4) Instill prescribed number of drops into the pouch, avoiding contact of dropper with eye or lashes. 5) Apply gentle pressure to the Lacrimal punctum (inner corner of eye) for 1-2 minutes to minimize systemic absorption, especially important for beta-blocker drops.
A Word from Your Senior Nurse
"Eye injuries can be terrifying for patients because vision is so precious. Your calm, knowledgeable assessment and clear instructions are crucial. When you see that tell-tale blood in the anterior chamber, you're not just identifying hyphema—you're triggering a cascade of protective interventions to save that patient's vision. Remember, in nursing, we treat the whole person. The teenager with the hyphema is scared. Reassure them, explain everything you're doing, and be their advocate for strict compliance with restrictions. That holistic care is what makes the difference between a good outcome and a complicated one."
Hyphema — Bleeding into the anterior chamber of the eye, a common complication of blunt ocular trauma.
Anterior Chamber — The fluid-filled space inside the eye between the cornea and the iris/pupil.
Intraocular Pressure — The fluid pressure inside the eye. Normal range is 10-21 mmHg. Elevated IOP is a serious complication of hyphema.
Secondary Glaucoma — Increased intraocular pressure resulting from another eye condition, such as hyphema blocking the drainage angle.
Cycloplegic — A type of eye drop that paralyzes the ciliary muscle, used in hyphema to reduce pain and prevent adhesions.
