When teaching a client with Meniere's disease, which instruction is critical for the nurse to include?

Meniere's disease is an inner ear disorder that can affect balance and hearing. One of the key components of managing this condition is to minimize the risk of exacerbating the symptoms, which include vertigo and balance issues. Avoiding sudden movements is critical because rapid changes in position can trigger or worsen vertiginous episodes. Sudden head movements can provoke an attack or increase the sensation of dizziness for the patient, making it essential to instruct patients to move slowly and deliberately.

While other choices do hold some relevance in managing Meniere's disease, avoiding sudden movements directly relates to reducing the immediate risk of dizziness and maintaining balance, which is crucial for the safety and comfort of the client.
