Reno did pretty well for an engineer when she kept the Hiawatha crew alive. She didn’t really treat any of them, but she approached the situation from an engineering standpoint since the body is basically a machine, and she kept the machine running.

Of the ones listed, Scotty and O’Brien would be the most likely to just store the injured in the pattern buffer for later, proper medical treatment (like Dr. M’Benga did in SNW), so I would say they would perform the best.

Edit: Didn’t see your transporter bit. I still think Scotty and/or O’Brien would improvise something along those lines and solve the problem with the pattern buffer.

I’m specifically disallowing the transporter truck because the scenario is about making them provide treatment.

How do you like my solution?

The alien blood corrodes away the bottom of your cup. Now what do you do?

I try to communicate with it.

It speaks only in disposable cup idioms. It says: “Red Solo, when the beer fell.” Now what do you do?

I eat the cup so that I can have its inner light.

You arrive without traveling, see all without looking, and do all without doing. You get a nifty flute souvenir. The ship explodes. Score: 0/100. Thank you for participating in the Kobay-ouchie Maru.
