Recently my mom was hospitalized. I got her a bunch of those nail polish tabs that go on like stickers but are actual polish, along with a few new files and such. I figured it'd something to do, looking nice is a self esteem boost, and the stickers are odor free so no worries on the fumes making her sicker/nauteated, and no spill factor to worry about if she's run down, or dry time.
Also does your friend knit or crochet? A "learn to knit!" kit with a starter set of needles, yarn and a basic pattern and "how-to" guide might be nice - 10 days is enough time to learn, mess up, learn from that and complete a simple project. Really this can go for almost any craft.
