Any sort of price range or style that you are looking for? Does she prefer gels or ballpoints or rollerballs? Any information you know can help narrow your options.
In general with the information given, I would look at the retro 51 Tornado line, they are very sturdy, and come in a plethora of color and design options including this appropriate looking one.

Retro 1951 is the brand. Metalsmith Series #VRR-1346 / Dr. Gray

I second the Retro51 pens. They come in a variety of styles, even some that might appeal to new doctors.

For example. The Dr. Gray pen references Henry Gray, an anatomist and surgeon. Your medical school friend might appreciate it. It also comes in a pen and pencil set.

What makes a pen EDC?

I like the feel of the Uni-Ball Signo 207 and Signo RT in my hand, and they lay down ink nicely. At ~$1.25, I don't fret when I lose one. I alternate those with a 4 1/2" by 3/8" pen that a vendor gave me. It's clipless, has a magnetic cap with a spongy stylus tip, and takes Parker jotter refills. If I could find it, I'd buy it in brass and other finishes.

I've got a couple of chrome Cross Classic pen and pencil sets I used to carry. Again, I like the feel, and they popular enough that you can get refills in several ink types. Those were just expensive enough that I worried about losing them. I didn't want to carry them loose in my pocket, but wasn't ready for a pen case, since I use them 1-2 day at most.

As usable works of art, someone just turned me on to Retro 1951, and I'm adding the glow-in-the-dark Dr Gray to my wishlist.
