HESI (Radiology) Which statement is NOT true regarding the receptors used for the paralleling technique? - ✔✔Size 1 recep tor 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 palate, 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 projection 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 techniq ue? - ✔✔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 b e centered on the ramus of the mandible while imaging the impacted third molar 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 s tatements are true The component of a panoramic unit that restricts the size 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 tolerable. -Receptors used for anterior exposures are m ore 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 dermatitis that is caused by frequent hand washing and us e of gloves? (Select the two that apply.) - ✔✔-
Use powder -free gloves -Dry hands thoroughly after hand washing and before donning gloves Which statement is true regarding infection control in dental radiography? - ✔✔Standard precautions pertaining to dent al radiography must be used for each patient. Which principle of infection control in the dental environment is associated with cleaning, sterilization, or disinfection of reusable patient care items? - ✔✔Principle 3 The human need most related to infect ion control is - ✔✔protection from health risks Cross -contamination is particularly problematic in oral healthcare, because saliva is invisible yet capable of containing high bacterial and viral particle loads. - ✔✔Both the statement and reason are correc t and related Dental healthcare professionals need to consult manufacturers of sensors and digital radiography components regarding specific disinfection products and procedures, because sensors and digital radiography components vary by manufacturer and can be expensive. - ✔✔Both the statement and reason are correct and related What is the recommended schedule of dosage for hepatitis B vaccination for dental healthcare personnel? - ✔✔Three -dose series followed by serologic testing Which type of infectio n control technique is used on digital sensors? - ✔✔Intermediate level disinfectant
