HESI (Radiology) Graded A+ Which statement is NOT true regarding the rec eptors used for the paralleling technique? ✅Size 1 receptor is bent to permit placement in the palate. During panoramic imaging, the dental radiographer asks the patient to swallow once, close the lips around the bite -block, and lift the tongue to the pa late, because this action helps prevent the formation of a dark radiolucent shadow. ✅Both the statement and reason are correct and related The projection used to image a lesion located in the posterior region of the mandible is the ✅lateral jaw projecti on Which condition is NOT evaluated using panoramic imaging? ✅Periodontal diseases To achieve parallelism between the receptor and the tooth, a dental radiographer should place the receptor ✅Away from the tooth Which step is NOT followed by the dental radiographer while using the paralleling technique? ✅Central ray of the x -ray is directed away from tooth contacts. What is the cause of a dropped receptor corner during the periapical technique? ✅The edge of the receptor placed askew from the incisal -occlusal surfaces of teeth The beam should be centered on the ramus of the mandible while imaging the impacted third m olar of a patient. The beam should be directed to a point just below the inferior border of the mandible when using the lateral jaw projection -body of mandible technique. ✅Both statements are true The component of a panoramic unit that restricts the siz e and shape of the x -ray beam is the ✅collimator When exposing the periapical receptors using panoramic imaging, which is the reason for starting the procedure with the anterior teeth? (Select the three that apply.) ✅-Anterior placements are more tolera ble. -Receptors used for anterior exposures are more comfortable. -Anterior placements allow patient to become accustomed to the beam alignment device. Which steps do the dental healthcare personnel take to minimize the development of nonallergic dermatit is that is caused by frequent hand washing and use of gloves? (Select the two that apply.) ✅-
