Task oriented means you are focused more on getting specific things done, rather than paying attention to the whole global picture surrounding the patient and the situation around you. Which is totally okay, at this stage of your career, just like everyone has said.
If you are curious about where this idea came from, it is described very well in Patricia Benner's nursing theory, From Novice to Expert. She described 5 stages: novice, advanced beginner, competent, proficient and expert. (Gee, can you tell I just wrote a paper for my nursing theory class
). You are somewhere in the advanced beginner area, moving along (its a continuum, not set stages) quite well especially if you can notice rhythm changes, and keep it together in a trauma scene in ED.
Keep asking questions whether some others like it or not, its the way to learn. Sometimes the key is in the way you ask, as in "check me on this, we are doing this because ....., is there anything else about it I'm missing?" That lets people know you aren't totally unaware of stuff, just wanting to know more. Find one person you really respect and ask if she will be your unofficial mentor for a while, someone you can come to without being made to feel stupid.
Most nurses in the proficient and expert stages also get all the tasks done efficiently, but can see many more things around the patient, implications of things, etc., so can do more than just tasks but also meet multiple needs of patients (not just the stuff that physical tasks take care of). Google some articles by Benner, she's really good.
