How is signal maximized to a digital image receptor? a. Lower milliamperage (mA) setting. b. Shorter exposure time. c. Higher source to image receptor distance (SID) value. d. Longer exposure time. The greatest signal strength is obtained with longer exposure time. The other responses reduce signal at the digital image receptor. Which is the best approach for speaking to a patient with a hearing impairment? a. Ask patient to adjust hearing aid volume. b. Speak in a low register. c. Talk very slowly. d. Do not make eye contact. Patients with hearing loss most often have difficulty hearing voices in a high register, so speaking in a low register is recommended. Speaking at a moderate pace is preferable, rather than very slowly. It is best to face the patient with hearing loss, so good eye contact is appropriate. Patients should not be advised to adjust their hearing aids in order to facilitate communication. Which protective feature is designed to reduce exposure to the patient during fluoroscopic procedures? a. Bucky slot cover. b. Magnification mode.
