TCDHA Rad Final Review 2023 updated to pass

TCDHA Rad Final Reviewradiation is defined as - correct answer a form of energy carried by waves or streams of particles a radiograph is defined as - correct answer a picture on film produced by the passage of x-rays through an object or body why are dental images important - correct answer many dental diseases are typically discovered only through the use of dental images who modified the paralleling technique with the introduction of the long-cone technique - correct answer F. Gordon Fitzgerald which of the following would you place in the patients mouth in order to take dental x-rays - correct answer image receptor the orbiting shell closest to the nucleus has the highest energy level - correct answer true the binding energy or binding force of an electron is - correct answer determined by the distance between the orbiting electrons and the nucleus ionization - correct answer an atom that gains an electron has a negative charge, and an atom that loses an electron has a positive charge ionizing radiation - correct answer radiation that is capable of producing ions by removing or adding an electron to an atom Heat is a byproduct of x-ray production. Which component of the x-ray tubehead dissipates the heat created by the production of x-rays? - correct answer insulation oil the head collimator - correct answer restricts the size of the x-ray beam which would you adjust if you wanted to create a larger electron cloud - correct answer mA in dental radiography, the term .......... is used to describe the mean energy or penetrating ability of the x-ray beam - correct answer quality (1) density is the overall darkness or blackness of a dental image (2) when the kilovoltage is increased while other exposure factors rain constant, the resultant image exhibits a decreased density and appears lighter - correct answer first statement is true; the second statement is false mA regulates the ........... of electrons produced at the cathode filament - correct answer quantity according to the inverse square law, if the length of the PID is halved, the resultant beam ............. as intense - correct answer one quarter (1) as kV, mA, and time increases, x-ray beam intensity decreases (2) as distance and filtration increase, the intensity of the x-ray beam increase - correct answer both statements are fals refers to the total amount of radiation that is received or absorbed - correct answer total dose (1) more radiation damage takes place with high dose rates (2) because a rapid delivery of radiation does not allow time for cellular damage to be repaired - correct answer both statements are true what should you do prior to taking x-rays to protect your patient from radiation exposure - correct answer proper prescribing of radiographs the thyroid collar - correct answer is recommended for all intraoral exposures the lead apron - correct answer is recommended for intraoral exposures
