CRITICAL THINKING QUESTIONS
1. A new patient waits outside the radiography operatory when the radiographer is setting it up for
use. The patient tells the assistant “Isn’t this overkill? I don’t have anything wrong with me.” How
might the dental radiographer educate this patient about infection control?
Discussion Guidelines: The dental radiographer should offer the following explanation: The majority of
2. A patient tells the dental radiographer that she has not been to a dentist in over 10 years
because she is afraid of contracting the AIDS virus. How should the dental radiographer respond?
Discussion Guidelines: The best way to reduce anxiety and fear is to educate the patient about
