New to orchids, a few questions

[Ink]

Hello-

This afternoon, my mother gave me a neglected orchid from her office. Always up to the task of rejuvenating plants, I gladly accepted it. I even bought "Orchids for Dummies" to brush up on my orchid how-to. Sadly, the poor thing looks like no one has tended to it for quite some time. No one even remembers what color the flowers were. Being new to orchids, I can't even identify what kind of orchid it is. So I took some pictures of it and am hoping to have a few of my questions answered. First and foremost, the stem looks completely dead. To the touch it feels dry, like a twig. There's no evidence of buds on the stem, either. It has four leaves, which look like the saving grace of the plant. They're dark green and look completely healthy. I've been reading around on how to handle brown stems, most articles say to cut it off, sometimes at the base of the plant near the leaves. Others say to look for "nodes" and cut about an inch above those. I can't identify much on it, so I was hoping someone would help. Also, I've no idea the last time it was re-potted. It seems to be sitting in a mossy substance, not potting soil, and it was dry as a bone when given to me. I watered it promptly. Hoping to save this plant, what should I do next? I'm afraid to do anything drastic like cut the stem off, fearing I'd harm the plant further. Here it is:






Hopefully, a member here can identify it and from there I'll have an easier time asking for advice.

Thank you-
