NG out-what to do?

So I'm taking care of a pt whose had an NG down to low int. suction for a few days d/t possible bowel obstruction. This day I'm taking care of her, she finally has a normal, brown, loose, hemoccult negative stool, cdiff negative, no N/V for 2 days, voiding, ambulating, afebrile. Had auscultated and noted gastric contents a few hours prior to all this..
The aid comes to get me after AM care, saying it does "sound right". I walked in the room to the pt gagging/choking, sitting up in the chair. I could hear the suction in her throat. I have worked in the hospital for about 6 months now. My first reaction was to pull the tape off her nose and tube out of her throat. Not even 3 inches of tubing was left..Was that right? I work on a busy floor, and am initimidated by some of the nurses. I know I question them to death sometimes....I hate always asking, "did I do this right"? or "what would you do?" Was that the right thing to do? The doc was there, so he was aware. He didn't order it to be put back down and new abd xrays since she was doing so well....
