A nurse is assessing a 58-year-old client who has been diagnosed with ocular melanoma. Which assessment finding would be most concerning and require immediate attention?
1Complaint of mild eye fatigue after reading
2Sudden onset of flashing lights and floaters in the affected eye✓ 정답
3Gradual decrease in peripheral vision over several months
4Presence of a small, pigmented lesion on the iris
해설
Sudden onset of flashing lights and floaters indicates possible retinal detachment, a serious complication of ocular melanoma requiring immediate intervention to prevent permanent vision loss. Other findings are less urgent or expected in the disease course.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to recognize a vision-threatening emergency in a patient with a known diagnosis of ocular melanoma. Ocular melanoma is a malignant tumor of the eye, often arising from the uvea (choroid, ciliary body, or iris). A critical complication of posterior uveal (choroidal) melanoma is exudative retinal detachment. The tumor can leak fluid, causing the retina to separate from the underlying choroid. This is an ophthalmologic emergency.
Answer Rationale: Key Point! The sudden onset of flashing lights (photopsia) and floaters is a classic presentation of acute retinal detachment. Flashing lights are caused by the retina being mechanically stimulated as it pulls away. Floaters can represent blood or pigment cells released into the vitreous. For a patient with ocular melanoma, this symptom is a red flag for tumor-related retinal detachment, requiring immediate ophthalmologic evaluation to potentially save vision.
Distractor Analysis:
1. Complaint of mild eye fatigue after reading: This is a common, non-specific complaint not indicative of an acute complication from the melanoma.
3. Gradual decrease in peripheral vision over several months: While this could be related to tumor growth, its gradual nature does not signal an immediate emergency like a sudden retinal detachment. It requires follow-up but is not the most concerning finding in this context.
4. Presence of a small, pigmented lesion on the iris: This finding might be the melanoma itself (if it's an iris melanoma) or a benign nevus. It is an expected finding in the diagnosis, not an acute complication requiring immediate action.
Related Concepts: Nurses must understand the difference between chronic, expected symptoms of a disease and acute, catastrophic complications. The NCLEX-RN often tests the ability to prioritize care based on the urgency and potential for harm. Retinal detachment leads to permanent vision loss if not treated promptly, making it the highest priority.
Concept Summary
Concept
Description
Nursing Implication
Ocular Melanoma
Malignant tumor of the uvea (choroid, ciliary body, iris).
Monitor for complications like retinal detachment, metastasis (often to the liver).
Retinal Detachment
Separation of the neurosensory retina from the retinal pigment epithelium.
Ophthalmologic emergency. Symptoms: Sudden flashes, floaters, "curtain" or shadow over vision.
Photopsia
Perception of flashing lights.
A key subjective symptom of retinal traction or detachment.
Floaters
Spots, strands, or cobwebs in the visual field.
New onset or sudden increase can indicate vitreous hemorrhage or retinal tear.
Pathophysiology: Choroidal melanomas grow and can cause exudative retinal detachment by leaking serous fluid underneath the retina. They can also lead to vitreous hemorrhage.
Anatomy: The retina is the light-sensitive neural layer. Detachment deprives it of oxygen from the choroid, leading to photoreceptor cell death.
Treatment Context (Not in question but related): Management may include radiation plaques (brachytherapy), laser therapy, or enucleation (eye removal). Post-procedure, nurses monitor for pain, infection, and signs of increased intraocular pressure.
Memory Tips
Acronym for Retinal Detachment Symptoms: "Flashes, Floaters, and a Falling curtain" (the 3 F's).
Link: Think of ocular Melanoma -> Major complication -> Mechanical/Exudative retinal detachment -> Must act immediately.
High-Frequency NCLEX Topics
The NCLEX-RN frequently tests priority-setting and complication recognition. Knowing the signs of emergencies for specific conditions (like retinal detachment with eye trauma or tumors) is a classic question style. The exam expects you to differentiate between "expected" and "ominous" symptoms.
Watch Out for Question Variations!
Instead of asking for the "most concerning finding," the question could ask: "The nurse should report which finding to the provider immediately?"
The scenario could change to a post-operative patient after cataract surgery (also at risk for retinal detachment).
It could be paired with a nursing action: "Which action should the nurse take first?" (Answer: Notify the provider/ophthalmologist immediately and instruct the patient to limit activity).
Nursing Clinical Practice GuideClinical Scenario: Mr. Johnson, 58, is in the oncology clinic for a follow-up visit after being diagnosed with a choroidal melanoma in his left eye 3 months ago. He is scheduled for radiation plaque therapy next week. During your assessment, he nervously says, "Nurse, last night I started seeing little lightning bolts out of the corner of my left eye, and now there are a bunch of new dark spots floating around."
Nursing Intervention Strategy:
Immediate Assessment: Stay calm but act with urgency. Ask clarifying questions: "Is there a shadow or curtain covering part of your vision?" Assess visual acuity quickly if possible (e.g., have him cover the right eye and read something). Do not apply pressure to the eye.
Priority Action: This is not a "wait and see" situation. Immediately notify the ophthalmologist or oncologist. Explain the patient's new-onset symptoms suggestive of retinal detachment.
Patient Safety and Precautions: Instruct the patient to limit physical activity (avoid bending, lifting, straining) to prevent further detachment. Keep the head elevated. Arrange for immediate transportation to an eye emergency department if directed by the provider. Do not allow the patient to drive himself.
Documentation: Precisely document the patient's report: "Patient reported sudden onset of flashing lights (photopsia) and new floaters in left eye at [time]. Provider notified, patient instructed to remain on bedrest with HOB elevated, awaiting further orders."
Nursing Procedure & Medication Flow
While not a procedure per se, the nursing priority is rapid communication and preparation:
Communication: Use SBAR (Situation, Background, Assessment, Recommendation) when calling the provider: "S: Mr. Johnson with ocular melanoma is reporting new flashes and floaters. B: He has a known choroidal melanoma. A: Sudden onset of photopsia and new vitreous floaters in the affected eye. No trauma. R: I have instructed him to limit activity. Do you want him seen in the ER or can he come directly to your clinic immediately?"
Medication Context: There are no direct emergency medications for retinal detachment administered by the nurse. Treatment is surgical (e.g., pneumatic retinopexy, scleral buckle). Post-operatively, nurses may administer antibiotic and steroid eye drops to prevent infection and inflammation.
A Word from Your Senior Nurse
"Eyes don't have a 'second chance.' Vision loss from a detached retina can be permanent if not treated within hours to days. As a nurse, your most powerful tools are your assessment skills and your voice. When a patient describes flashes and floaters, especially with a history like ocular melanoma, your internal alarm bells should ring. You are the advocate who bridges the patient's concern to the life-saving action of the specialist. In studying, always link the patho (tumor leaks fluid -> retina detaches) to the symptom (flashes) to the action (call NOW). That's how you move from memorizing to truly protecting your patients."
Ocular Melanoma — A malignant tumor arising from melanocytes in the eye, most commonly in the uvea (choroid, ciliary body, or iris).
Retinal Detachment — A vision-threatening emergency where the neurosensory retina separates from the underlying retinal pigment epithelium, often causing sudden flashes, floaters, and vision loss.
Photopsia — The subjective visual sensation of flashing lights, often caused by mechanical stimulation of the retina (e.g., from traction or detachment).
Floaters — Spots or strands in the visual field caused by opacities (e.g., blood, pigment cells) in the vitreous humor. A sudden increase is a red flag.
Exudative Retinal Detachment — A type of retinal detachment where fluid accumulates beneath the retina due to leakage from a source such as a tumor (e.g., ocular melanoma) or inflammation, rather than a retinal tear.
