The Gallup is different for different job types, so you may have different questions than what I had for my job interview (for a technical position in the medical device industry).
Here are some of the questions that I had to answer:
How important is it to work for a well respected company?
Do you get restless?
Is credibility important to you?
Do you like to share things?
Do you overly challenge others?
Do you like to start a task right away or think of alternative methods ahead of time?
Do you have a sense of the right thing to do?
Do you take pride in your ability to follow through on your commitments?
Can you give an example of a time you followed through despite adversity?
Are you more of an underachiever or overachiever compared to other people?
The rest of the questions I had to answer are over on my blog:

A lot of the questions are ridiculous -- you could write a book for an answer. I am a person who sees things as shades of grey, not black/white. But they want VERY SHORT, to the point answers. Yes or No, and maybe a one sentence elaboration. Only rarely should you give more info than that. They are timing you and the amount of time you take factors into your results. Also the person giving you the survey IS NOT experienced in your line of work. So you should not expect whoever gives it to you to have any understanding of nursing, so you have to keep technical examples or industry lingo to a minimum.
A lot of the questions are overlapping/repetitious. So they'll ask you about honesty, then later about truthfulness, then later about integrity, and they are looking for you to be consistent across answers.
Definitely do it somewhere where you will not be distracted. Stay relaxed, and tell them what they obviously want to hear. (I hate even typing that, because it feels so fake... but that's how this thing works. I took it twice and "failed" the first time because I treated it like a real job interview. The second time I "played the part" of an ideal perfect happy-go-lucky everything is shiny and perfect employee, and I did great.)
Good luck!
