Thanks for the commentsn and encouragement guys.
Yeah, my instructor had thought I gave one before. She helped me with the G-tube meds then she goes "Okay, well, you know the shot goes in the abdomen 2 inches from the umbilicus, so go ahead, I've gotta help another student." then she left. I didn't even know how to get the goofy cap off the needle, but my floor nurse helped me with that, then I gave it no problem.
Then I turn around and houskeeping had pulled the sharps container to change it, but she hadn't come back yet. My FIRST shot and housekeeping decided THEN to pull the sharps container
So I capped the needled by the one-handed scoop method and walked outside. She was coming down teh hall with a new one and saw me standing there, so she held it up so I could drop it in. Like I wasn't nervous enough LOL
