An RN/EMT? You probably have half the convincing done for you.

I'd say something a little more robust than a Photon, like a Mag Solitaire, or (because I'm going to catch heat for suggesting the evil Mag) a similiarly designed LED light. Either way, running off AA or AAA. I might wrap a few feet of duct tape around the light body, so you can safely bite down on it without chipping teeth, and because, well, it is duct tape. At the very least, a little electricians tape.

For the knife/multitool, I really like the Micra over the S4 or the SAK Classic, but have her handle them all.

For whistle, the new Fox that Doug helped design- flat and loud.

I would add a bit of paracord. I like a three-plait braid using doubled strands, and split the pairs into individual braids, and whip the ends.
