Practice questions are original. This app is not affiliated with DANB, a state board, Prometric, Credentia, or Pearson. Items are written for this app. They cover radiation safety, infection control, and general chairside setup. They are not retired exam questions, and a score here is not a credential.
The free account includes 10 questions. A $9 purchase includes 300. Lifetime removes that cap. Each set is five questions, and the explanation sits under the choice you pick.
