Choice A reason: This is not an appropriate intervention for this client because physical therapy can help with improving joint mobility and function, but not with eating difficulties. The nurse should encourage the client to perform range-of-motion exercises and apply heat or cold therapy to the affected joints as prescribed.

Choice B reason: This is not an appropriate intervention for this client because having an assistive personnel feed the client can compromise the client's dignity and independence. The nurse should respect the client's preferences and abilities and provide assistance only when needed.

Choice C reason: This is not an appropriate intervention for this client because a pureed diet is not necessary for this client unless they have swallowing problems or dental issues. The nurse should offer the client a balanced and varied diet that meets their nutritional needs and preferences.

Choice D reason: This is the correct answer because applying foam handles to the client's eating utensils can make them easier to grip and manipulate, thus enhancing the client's self-feeding ability and comfort. The nurse should also provide other adaptive devices, such as plate guards, non-slip mats, or angled spoons, as needed.
