Questions About Becoming A CNA?

<p>I've thought about taking a course this summer to become a CNA so that I can work in hospitals and stuff during college (I'm a freshman next fall). I live in Iowa, but I might take the test in Nebraska since there are more courses in Omaha, which is 20 minutes away from me. However, I have a few questions:</p>

<p>-Am I allowed to take the course in a different state since I have to take a test from the State at the end?
-Once I pass that test, am I only allowed to be a Nursing Assistant in that state? Because I'm going to college in Illinois next year, so it'd be pointless to only be able to practice NA in Nebraska or Iowa.</p>

<p>Thanks!</p>
