NCLEX Review Guide: Ménière's Syndrome

Understanding Ménière's Syndrome

• Ménière's syndrome is a chronic inner ear disorder characterized by excess endolymphatic fluid (endolymphatic hydrops) causing increased pressure in the inner ear. This fluid imbalance affects both hearing and balance functions, leading to episodic attacks of debilitating symptoms.
• The classic triad includes vertigo, tinnitus, and sensorineural hearing loss, often accompanied by aural fullness. Episodes typically last 20 minutes to several hours and can be unpredictable in timing and severity.

Priority Nursing Actions

• Safety is the priority during acute episodes due to severe vertigo and fall risk. Assist with ambulation, keep bed in low position, and ensure call light is within reach at all times.
• Assess for nystagmus, hearing acuity, and balance using Romberg test and Weber/Rinne tests. Document the affected ear and degree of hearing loss for baseline comparison.

1. Position client in quiet, darkened room
2. Maintain bed rest during acute episodes
3. Administer prescribed antiemetics and vestibular suppressants
4. Monitor for signs of dehydration from vomiting
5. Provide emotional support and reassurance

Pharmacological Interventions

• Acute episode medications include meclizine (Antivert) for vertigo, promethazine (Phenergan) for nausea, and diazepam for severe cases. These medications help control symptoms but do not cure the underlying condition.
• Prophylactic treatment may include diuretics (hydrochlorothiazide) to reduce endolymphatic pressure and betahistine to improve inner ear circulation in some cases.

Dietary Modifications

• Implement low-sodium diet (1500-2000mg daily) to reduce fluid retention and endolymphatic pressure. Teach clients to read food labels and avoid processed foods high in sodium.
• Limit caffeine, alcohol, and nicotine as these substances can trigger episodes by affecting inner ear circulation and fluid balance.
