sheriff's office! yikes! I'm not sure if I could recommend doing that. Here in NY, you have to register to take the test at a Pearson center and also register with the state board of nursing. You then get an authorization to test (ATT) that allows you to choose a test date and sit for the exam at the Pearson center. On the day of your exam, you walk with your ATT (just a sheet of paper), they compare it with your ID, and photograph and fingerprint you. That's it. It may be different in Texas, I'm not sure.
