[Which of the following is composed of solid-state silicon-based diodes?] Step-down transformer Rectifier Cathode Timer None . [Which of the following is true concerning holding of patients for radiographic exams?] May be performed routinely to obtain a diagnostic exam Should be done only when absolutely necessary, and then the holding should be done by a competent radiographer so that a repeat will not be needed Should be done only when absolutely necessary, and then the holding should be done by a nonpregnant member of the patient’s family May be performed using a student radiographer to hold because students are not exposed as often as staff radiographers None .
