Disease of the inner ear characterized by recurring episodes of vertigo, tinnitus, and deafness?

Appeared in: AIIMS Nagpur NO - 2018

Explanation

Meniere's disease is a disorder of the inner ear affecting balance and hearing.
It is defined by a classic triad of symptoms: episodic vertigo (dizziness), tinnitus (ringing in the ear), and fluctuating sensorineural hearing loss.
The underlying cause is believed to be an abnormal amount of fluid (endolymph) in the inner ear, a condition known as endolymphatic hydrops.
Attacks can be severe and disabling, often accompanied by nausea and vomiting.

Option A: Syncope is the medical term for fainting. It is a temporary loss of consciousness due to decreased blood flow to the brain, not a disorder of the inner ear.
Option C: Glaucoma is a disease that damages the eye's optic nerve. Its symptoms relate to vision loss, not hearing or balance.
Option D: Hydrocephalus is the buildup of fluid in the ventricles deep within the brain. It increases pressure on the brain and is a neurological condition, not an inner ear disorder.

Clinical Relevance

Nursing practice connection: Knowing Identification of inner ear disorders based on clinical manifestations helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Patient safety is the top priority during a vertigo attack. Nurses must implement fall precautions, such as keeping the bed in a low position with side rails up and assisting with all ambulation.
Dietary teaching is a key nursing intervention. Patients are often advised to follow a low-sodium diet to help reduce fluid retention in the inner ear.
The unpredictable nature of Meniere's attacks can cause significant anxiety and depression. Nurses should provide emotional support and refer patients to support groups.

How to Approach the Question

First, break down the question to identify the key clinical features presented: 1) affects the inner ear, 2) recurring vertigo, 3) tinnitus, and 4) deafness (hearing loss).
This combination of three specific symptoms (vertigo, tinnitus, hearing loss) is a classic medical triad.
Evaluate each option against this triad.
Option A (Syncope) is fainting, which doesn't match.
Option C (Glaucoma) is an eye disease, which doesn't match.
Option D (Hydrocephalus) is fluid on the brain, which doesn't match.
