A nurse is caring for a client diagnosed with labyrinthitis. Which nursing intervention should be the priority?

The priority is implementing fall precautions and assisting with ambulation due to severe vertigo and balance disturbances that increase fall risk. Other interventions are secondary to safety.

Understanding the Priority: Safety in Labyrinthitis

The client is experiencing acute labyrinthitis, an inflammation of the inner ear structures (the labyrinth) that typically follows an upper respiratory infection. This condition disrupts the vestibular system, leading to the hallmark symptom of severe vertigo—a false sensation that the environment is spinning. The sudden onset of this symptom, combined with nausea and vomiting, creates a critical safety risk. In the hierarchy of nursing priorities, safety and injury prevention take precedence over other interventions.

While the provided evidence ^[1] focuses on Benign Paroxysmal Positional Vertigo (BPPV) rather than labyrinthitis, the principle of fall prevention is directly transferable. The study demonstrated that nurse-directed interventions, including fall-prevention education, significantly improved functional balance scores, such as the Berg Balance Scale (BBS), in patients with vertigo ^[1]. This reinforces that a structured approach to safety is a measurable and effective nursing action. For a client with labyrinthitis, the immediate application of this principle is to implement fall precautions and provide physical assistance, as the vertigo is constant and severe, not just triggered by position changes.

Analyzing the Incorrect Options

- Option 1: Encourage frequent movement. This is contraindicated in the acute phase of labyrinthitis. Movement will exacerbate vertigo, nausea, and vomiting. The priority is to keep the client still and safe, not to mobilize them.
- Option 3: Administer prescribed antibiotics immediately. Labyrinthitis is most often viral or post-viral in etiology, especially following an upper respiratory infection. Administering antibiotics without a confirmed bacterial cause is not the priority nursing action and would be ineffective. The evidence on sudden sensorineural hearing loss ^[2] discusses corticosteroid treatment, not antibiotics, further supporting that inflammation, not bacterial infection, is the typical target of pharmacotherapy in inner ear conditions.
- Option 4: Perform frequent neurological assessments every 15 minutes. While assessment is important, the client’s symptoms are classic for labyrinthitis. The immediate threat is not a change in neurological status but a physical fall due to the existing, severe vertigo. A focused assessment is necessary, but the priority intervention is to act on the known risk by implementing safety measures. The frequency of every 15 minutes is also not supported by the clinical presentation as the highest priority action.

Clinical Reasoning and Evidence Connection

The core of this clinical decision is applying the nursing process. The assessment data (severe vertigo, nausea, vomiting) leads to a clear nursing diagnosis: Risk for Falls. The planning and implementation phases must therefore prioritize an intervention that directly mitigates this risk. The study on nurse-directed interventions for vertigo validates that a focus on safety and mobility education yields significant, quantifiable improvements in balance and physical performance ^[1]. By implementing fall precautions and assisting with ambulation, the nurse directly addresses the most immediate threat to the client's physical safety. This action is a foundational, independent nursing intervention that does not require a provider's order to initiate, making it the correct and immediate priority.
