| Question | Answer |
|---|---|
| Moving the foot and toes downward is | plantarflexion |
| Movement in the form of a circle is the definition for | circumduction |
| The opposite term for supination is | pronation |
| What type of projection is created with the CR directed along or parallel to the long axis of a structure or anatomic part? | axial |
| A patient is erect facing the image receptor. The left side of the body is turned 45 degrees toward the image receptor. The CR enters the posterior aspect of the body and exits the anterior. What is this radiographic position? | LAO |
| A recumbent position in which the patient is lying on the right anterior surface with the body rotated toward the image receptor is termed | left anterior oblique |
| The position in which the head is lower than the feet | Trendelenburg |
| A longitudinal plane that divides the body into equal anterior and posterior parts is the _____ plane | midcoronal |
| The vertical plane that divides the body into equal right and left halves describes the _____ plane | median or midsagittal |
| Which of the following bones is classified as a long bone? | humerus |
| Which of the following body systems helps to regulate body temperature? | nervous |
| Modern patient radiation protection methods should include | he placement of shielding to protect the lens of the eye and thyroid gland |
| The material commonly used for shielding against radiation exposure in protective aprons and gloves is | lead |
| Chest radiographs and upright abdominal studies are conveniently performed using | upright cassette holder or Bucky |
| The x-ray tube has a positive and negative side to its operation. Because of this, the x-ray tube is considered to electrically be a | diode |
| The total quantity of X-ray photons produced during an exposure is determined by the | mAs |
| The X-ray tube component that stops the stream of electrons and produces the X-ray beam is called the | anode |
| Why are bony positioning landmarks palpated or referenced during radiographic setup? | To ensure accurate central ray aligment with the target internal anatomy and minimize diagnostic error or repeated exposures |
| What are the standard routine views for a hand or wrist exam | PA oblique |
| why are multiple views requiered for hand or wrist ? | multiple orthogonal views prevent overlapping structures from hiding fractures or dislocations |
| how does a radiographer adjust exposure techniques when imaging a limb wrapped in a fiberglass cast | increase the peak kilovoltage (kvp) by appx 3 to 4 kvp to penetrate the extra material density |
| What is the primary purpose of automatic exposure contro (AEC) in cinical radiography? | it automatically terminates the exposure once the ionazation chambers recieve sufficient radiation. |
| when and why is a radiographic grid placed between the patient and the image receptor? | grids are used when imaging body parts thicker than 10cm or when using hight kvp levels. |
| what are the 3 primary types of Xray tube support systems | overhead/ cealing suspension floor-to-ceiling/ floor suspension c-arm suspension |
| what is cephalic angulation of central ray | xray tube is tiltied longitudinally toward the patients head |
| what is caudal angulation of the central ray? | the tube is tilted toward the patients feet |
