A nurse is caring for a client with Ménière's syndrome who is experiencing an acute episode of vertigo. Which nursing intervention should the nurse implement first?
3Encourage the client to ambulate slowly with assistance
4Provide bright lighting to help the client maintain visual orientation
해설
Positioning in supine minimizes vestibular stimulation and prevents falls during acute vertigo. Administering antiemetics, ambulating, or bright lighting can worsen symptoms or increase risk.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing intervention for a patient experiencing an acute episode of Ménière's disease (Ménière's syndrome). The core pathophysiology involves endolymphatic hydrops, an abnormal accumulation of fluid in the inner ear's labyrinth. This pressure disrupts the vestibular system, leading to the classic triad of symptoms: vertigo, tinnitus, and sensorineural hearing loss. During an acute attack, the vertigo is severe, rotational, and often accompanied by nausea, vomiting, and nystagmus. The priority is Key Point!safety and symptom management by minimizing sensory input and stimulation to the vestibular system.
Answer Rationale: The correct answer is ① Place the client in a supine position. This is the Key Point! first action because it directly addresses the immediate safety risk (falls) and the pathophysiological trigger. Lying supine with the head still minimizes head movement, which reduces stimulation of the semicircular canals in the inner ear. This helps decrease the sensation of spinning (vertigo) and the associated nausea. It is a non-pharmacological, immediate intervention that the nurse can implement independently to stabilize the patient's condition before administering medications or other care.
Distractor Analysis:
- Watch out for confusion!② Administer prescribed antiemetic medication immediately: While antiemetics (e.g., meclizine, promethazine) are a crucial part of the medical management for acute episodes, they are not the first nursing intervention. The nurse must first ensure the patient is in a safe position to prevent injury from a fall, which could occur while preparing or administering the medication. Safety (positioning) precedes medication administration.
- ③ Encourage the client to ambulate slowly with assistance: This is contraindicated during an acute vertigo attack. Attempting to ambulate increases the risk of falls and will exacerbate vertigo and nausea due to increased head and body movement. Ambulation is encouraged after the acute episode subsides.
- ④ Provide bright lighting to help the client maintain visual orientation: This is incorrect and can worsen symptoms. Bright, flickering, or complex visual patterns can conflict with the distorted signals from the inner ear, worsening vertigo (a phenomenon related to visual-vestibular mismatch). The environment should be kept quiet and dimly lit to reduce sensory stimulation.
Related Concepts: Nursing care for Ménière's disease also includes a low-sodium diet to reduce endolymphatic fluid pressure, stress management, and safety education for the home environment (e.g., removing tripping hazards, using handrails). During an attack, the nurse should also maintain side rails up, provide an emesis basin, and speak in a calm, quiet voice.

Side-by-Side Comparison!
Condition
Key Feature
Priority Nursing Intervention During Attack
Ménière's Disease
Episodic, severe rotational vertigo with tinnitus/hearing loss.
Place patient supine, minimize all movement and sensory input.
Benign Paroxysmal Positional Vertigo (BPPV)
Brief vertigo triggered by specific head positions (e.g., rolling over in bed).
Perform/assist with canalith repositioning maneuvers (e.g., Epley maneuver).
Vestibular Neuritis
Sudden, severe vertigo without hearing loss, often post-viral.
Bed rest, antiemetics/vestibular suppressants, gradual mobilization.
Anatomy, Physiology & Pharmacology Points
- Anatomy: The inner ear (labyrinth) contains the cochlea (hearing) and vestibular system (balance: semicircular canals, utricle, saccule).
- Physiology:
- Endolymph: Fluid inside the membranous labyrinth. Imbalance in its production/absorption causes hydrops.
- Vertigo Mechanism: Hydrops distorts signals from semicircular canals to the brain, creating a false sensation of movement.
- Pharmacology:
- Vestibular Suppressants: Meclizine, dimenhydrinate. Reduce dizziness/nausea.
- Antiemetics: Promethazine, ondansetron. Control nausea/vomiting.
- Diuretics: Hydrochlorothiazide. May be used long-term to reduce endolymphatic fluid pressure.
Memory Tips
- Acronym for Priority: S.A.F.E. during a Ménière's attack.
- Supine position first.
- Assess safety (side rails up).
- Facilitate medication (antiemetic) after positioning.
- Ensure environment is quiet and dim.
- Ménière's Triad: Remember "VTH" – Vertigo, Tinnitus, Hearing loss.
High-Frequency NCLEX Topics
NCLEX frequently tests priority-setting and safety in acute situations. Ménière's disease is a classic example where a simple, independent nursing action (positioning) takes precedence over administering prescribed medication. The exam tests your ability to distinguish between an important intervention and the most immediate, safety-focused one.
Watch Out for Question Variations!
- Instead of asking for the "first" intervention, a question might ask: "The nurse is developing a plan of care. Which goal is the priority for a client during an acute Ménière's attack?" (Answer: Client will remain free from injury).
- A question could shift to patient education: "Which instruction should the nurse include in the discharge teaching for a client with Ménière's disease?" (Answer: Follow a low-sodium diet and avoid sudden head movements).
- It might combine with medication: "The nurse administrates meclizine to a client with acute vertigo. For which subsequent action should the nurse monitor?" (Answer: Drowsiness and advise against driving or operating machinery).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 58, with a history of Ménière's disease, calls for help, stating, "The room is spinning, and I'm going to be sick." He appears pale, diaphoretic, and is holding onto the bedside table.
Nursing Intervention Strategy:
1Immediate Action (Assessment & Safety)Calmly instruct Mr. Johnson not to move. Assist him to lie down supine in bed. Raise the side rails. Place an emesis basin and tissues within easy reach. Assess vital signs, noting any tachycardia or hypotension from the autonomic response.
2Symptom ManagementDim the lights and close the door to reduce noise. Administer the prescribed PRN antiemetic (e.g., promethazine 12.5 mg IM) after he is safely positioned. Document the onset, characteristics, and duration of the attack.
3Education & PreventionOnce the acute episode resolves, reinforce teaching: adherence to a < 2 g sodium/day diet, importance of stress reduction techniques, and the need to avoid driving or working at heights when feeling prodromal symptoms (e.g., fullness in the ear).
Patient Safety and Precautions:
1Fall RiskThe patient is at extreme fall risk during and immediately after an attack. Ensure the call bell is accessible and the path to the bathroom is clear. Assist with all ambulation initially.
2Medication CautionVestibular suppressants and antiemetics cause significant drowsiness. Monitor for oversedation.
Nursing Procedure & Medication FlowProcedure for Acute Vertigo Episode:
1. Ensure immediate safety: Guide patient to bed, supine position.
2. Raise side rails, lower bed height.
3. Provide emesis basin, quiet/dim environment.
4. Assess patient (vitals, symptom severity).
5. Administer prescribed antiemetic/vestibular suppressant.
6. Document: Time of onset, interventions, patient response.
7. Reassess frequently.Medication Administration:
- Common antiemetics: Promethazine (Phenergan®) – can be given IM/IV/PR. Watch out for confusion! IV administration must be diluted and given slowly to avoid tissue damage and severe hypotension.
- Vestibular suppressants: Meclizine (Antivert®) – typically oral. Onset is slower than IM antiemetics.
A Word from Your Senior Nurse
"In the whirlwind of an acute vertigo attack, your calm and decisive action is the patient's anchor. Remember your ABCs adapted for this situation: Alleviate movement, Bed rest, Calm environment. Positioning isn't just a task; it's a therapeutic intervention that directly alters the patient's sensory experience and prevents harm. On the NCLEX, they're testing your clinical judgment—can you see past the 'medication' answer to the foundational nursing action that keeps the patient safe first? That's the kind of thinking that makes a great nurse."
Ménière's Disease — A disorder of the inner ear characterized by episodic vertigo, tinnitus, and sensorineural hearing loss, caused by endolymphatic hydrops.
Endolymphatic Hydrops — Abnormal accumulation of fluid (endolymph) in the membranous labyrinth of the inner ear, leading to increased pressure and the symptoms of Ménière's disease.
Vertigo — The sensation of spinning or whirling, often accompanied by nausea and loss of balance, resulting from a disturbance in the vestibular system.
Vestibular Suppressant — A medication (e.g., meclizine, dimenhydrinate) used to reduce the sensation of dizziness and vertigo by depressing the labyrinthine function.
Sensorineural Hearing Loss — Hearing loss caused by damage to the inner ear (cochlea) or the nerve pathways from the inner ear to the brain. A key feature of Ménière's disease.
