Final answer:
Administering local anesthesia is not a standard part of preparing a patient for a radiographic series, which typically includes providing a lead apron, patient positioning, and placing a thyroid collar.
Step-by-step explanation:
When preparing a patient for exposure of a radiographic series, all of the following steps are included except administering local anesthesia. Providing a lead apron (Figure 32.7 and Figure 32.10), positioning the patient properly, and placing a thyroid collar are standard safety procedures to limit exposure to radiation. The use of fast films also helps reduce the time needed to obtain images, consequently decreasing the exposure to the imaged tissue. A lead apron and shielding around the x-ray tube are critical for protecting tissues that are not being imaged. However, administering local anesthesia is not a routine part of radiographic series preparation unless there is a specific medical procedure involved that requires it.
