For a client with Ménière's disease, unsweetened cranberry juice is an acceptable beverage choice, as opposed to caffeinated beverages, salt, or chocolate which should be avoided.
Step-by-step explanation:
A nurse providing dietary instructions to a client with Ménière's disease would recommend foods and fluids low in sodium, saturated fat, and added sugars.
