In case you don't already have them in your medicine cabinet, butterfly closures would be a good addition. I carelessly sliced open my left thumb with an Exacto knife yesterday afternoon, and without a butterfly would have had to go to town for stitches.
The ones we have are Johnson & Johnson, size medium (1-3/4" long) and come in a back of ten for less than $2. They are latex, so wouldn't be good for anyone with a latex allergy.
