how do I target one random person but give them 2 effects and one item

I am making a Minecraft commands map and need to give a random player two effects and one item.

I understand that each effect/item needs to be given in a separate command. The problem is, @r targets a random player each time, but I need the effects and items to be given to the same randomly targeted player.

How can I give these effects/items to the same player?
