To Travel or Not?

Hi everyone!
I'm just looking for some advice here. I work in a 20 bed ER, with no Trauma, spinal cord injuries, or pediatrics. However, since we're a small rural hospital we do get exposure to those. I have been a nurse for 14 months, and worked as a tech for 13 months before that. My question is this. Could I travel to an ER since I don't have a lot of trauma/peds/spinal cord experiance? I would hate to take an assignment and be in way over my head with no way out! Thanks for your time and help!
