Final answer:
Patients with Ménière's disease should ask for assistance when getting out of bed due to the risk of dizziness and falls.
Step-by-step explanation:
The appropriate response to a client with Ménière's disease asking if they can ambulate independently would be: "C. Please ring for assistance when you wish to get out of bed". Ménière's disease can affect balance and may cause dizziness or vertigo, which puts the client at risk for falls when ambulating. Therefore, it is best practice to ensure safety measures such as asking for assistance before attempting to ambulate.
