Explanation

Acute angle-closure glaucoma (AACG) is an ocular emergency caused by a sudden blockage of aqueous humor outflow, leading to a rapid and severe increase in intraocular pressure (IOP).
The classic triad of symptoms for AACG includes severe unilateral eye pain, blurred vision with colored halos around lights, and a red, congested eye (ocular redness).
These symptoms are a direct result of the acutely elevated IOP causing corneal edema and nerve irritation.
Systemic symptoms like nausea, vomiting, and headache are also common due to the intensity of the pain.

Option B: This option describes painless tunnel vision and loss of peripheral vision, which are the classic signs of chronic open-angle glaucoma, not acute angle-closure glaucoma.
Option C: This option incorrectly mixes an acute symptom (severe eye pain) with a chronic symptom (tunnel vision). Tunnel vision is a sign of long-term, progressive optic nerve damage, not a feature of an acute attack.
Option D: The absence of pain is a key feature that makes this option incorrect. Acute angle-closure glaucoma is defined by its severe, often excruciating, pain.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Clinical manifestations of acute angle-closure glaucoma as background academic context rather than a clinical decision trigger.
Recognizing the symptoms of acute angle-closure glaucoma is critical for nurses because it is an ophthalmic emergency requiring immediate treatment to prevent irreversible vision loss.
A nurse's priority is to facilitate an urgent ophthalmology consultation. While waiting, the patient should be kept comfortable, and measures to lower IOP (e.g., administering prescribed medications like acetazolamide or miotic eye drops) should be initiated promptly.
What if? If a patient with these symptoms also reports taking an over-the-counter cold medication containing a decongestant, the nurse should recognize this as a potential trigger. Decongestants can cause pupillary dilation, which can precipitate an angle-closure attack in a susceptible individual.

How to Approach the Question

First, identify the core concept of the question: 'acute angle closure glaucoma'. The word 'acute' is a major clue, indicating a sudden and severe onset.
Next, analyze the options based on your knowledge of acute versus chronic conditions. Look for a set of symptoms that reflects a rapid, painful process.
Recall the classic triad for AACG: severe pain, blurred vision/halos, and a red eye. Evaluate which option best matches this triad.
Eliminate options that describe chronic, progressive, or painless symptoms. 'Tunnel vision' is a hallmark of chronic glaucoma, and 'no pain' is the opposite of what occurs in an acute attack.
Select the option that contains the most accurate and complete set of symptoms for an acute attack.
