| Question | Answer |
|---|---|
| Attenuation | a beam of radiation is reduced in energy when passing through tissue or other materials |
| computed radiography | uses a photostimulae phosphor plate (psp) to produce radiographic images |
| Kilovoltage Peak KVP | is the chief controlling factor of radiographic contrast Controls quality |
| Milliampere - second mAs | controls the amount of radiation produced by the x-ray tube Controls quantity |
| Direct capture image recptor | does not use light during exposure |
| The 15% rule | primarily helps explain the effect of kilovolatge peak on exposure Will double the exposure or half the exposure |
| Iodine compunds, air , and barium sulfate | are considered radiographic contrast mediums. Water is not a contrast medium |
| direct capture imaging | uses a flat panel to make digital image |
| Motion is the most common cause of | radiographic unsharpness |
| increasing the KVP does what | it will double the exposure |
| exposure indicator | is representative of the quantity of exposure recieved by a digital image receptor |
| Cathode produces | the electrons |
| the selection of radiographic exposure factors are performed by the operator at the | control console |
| mAs is calculated by | multiplyingmmilliamperage by th exposure time mAxS |
| Collimator assembly is | located on the tube and controls the beam of light size |
| X-rays need what to be produced | Source of electrons, rapid accleration, rapid decleration, It does not need protons |
| Pair production | the incoming x-ray photon must be at least 1.02 MeV |
| photoelectric interaction | costitutes the greatset hazard to patients in radiography |
| The gray is used to measure | the amount of enrgy absorbed in any medium |
| the law of Bergonie and tribondeau | the characteristics that determine the sensitivity of a cell to radiation are:mitotic activity and structure and function of the cell |
| lead absorbs x-ray through the process of | the compton effect |
| the annual whole body effective dose limit to the occupational worker is | 50 mSV (5rem) |
| AlARA | As low as reasonably achievable |
| the cardinal princeples of protection from ionizing radiation | TIme distance and shielding |
| Exposure , absorbed dose, and dose equivalant are | important to radiography |
| the highest level of Maslow's hierarchy of needs is | self actualization |
| non- verbal communication | tone of voice speed of speech facial expressions and position of speakers extremities and torso |
| where to wear a dosimeter | on collar bone facing out |
| stages of the dying process | acceptance unusual high alertness and response to conversations |
| Most basic need according to maslow | Food water and shelter |
| a fear of the unknown is common emotion of most | patients entering the hospital |
| Emotional intelligence | clearly understanding your emotions when handling patient and families |
| inpatient | someone who has been admitted to the hospital for diagnosis or treatment |
| Stages of grieving | denial, isolation, anger, bargaining, depression, and acceptance |
