What additional item may a resident desire while using a portable commode?

While using a portable commode, a resident may desire a robe for several reasons related to comfort and privacy. The robe can provide warmth and help maintain the individual's dignity in situations where they might feel exposed. It allows them to feel more comfortable while using the commode, especially if it is placed in an area where they may not have complete privacy.

Other materials, such as magazines or smartphones, could be used for distraction or entertainment, but they do not address the immediate needs of warmth and modesty like a robe does. A blanket could also provide warmth, but it's less practical in the context of using a portable commode due to its bulk and the potential for it to interfere with the resident's ability to use the commode safely and effectively. Therefore, a robe is the most appropriate item that enhances the experience of using a portable commode in terms of comfort and privacy.
