RAD135 Week 1 Exam
Trauma, mobile and Surgical radiography
| Question | Answer |
|---|---|
| Which of the following would be considered a trauma radiography guideline? 1. Remove all splints 2. Do not move the patient unless necessary 3. Obtain a minimum of two radiographs of each body part | 2 and 3 |
| When imaging a patient in a fracture frame or traction device, the radiographer should: | angle the central ray or adjust the IR to obtain the best radiograph possible |
| Which two preliminary steps should the radiographer perform before beginning a mobile x-ray examination? | Introduce yourself to the patient and family. Determine the correct patient is in the room. |
| How long should the patient lie in the decubitus position before making the exposure during a mobile decubitus chest examination? | 5 minutes |
| Patient comes into the ED on a backboard, with blunt force trauma to the head and a C-Collar in place. The physician orders a lateral skull/Cranium - how and where should your CR be positioned to obtain this projection? | The CR should be horizontal, centered 2 inches above the EAM |
| Institution-approved attire worn in the OR: can be used regardless of condition. is not necessary in the semi-restricted areas. can be worn over 2 days. should be fresh for each shift. | Should be fresh for each shift |
| The trauma radiographer must ensure other team members are protected from unnecessary radiation. Which practices will accomplish this? | Lead aprons for all personnel who remain in the room during exposures. Announcement of impending exposure to allow nonessential personnel to exit the room. |
| Which of the surgical procedures require the C-arm to be positioned between the patient's legs? | hip pinning |
| Which of the following should be available on every mobile radiography machine? 1. Lead apron 2. Radiographic technique chart 3. Measuring caliper | 1, 2 and 3 |
| Which projection must be evaluated before taking any other images on a trauma patient? | Lateral projection of the C-spine, dorsal decubitus position |
| T/F Communication with the patient is imperative, even if the patient is or appears to be unconscious or unresponsive. | True |
| According to federal regulations, the source-to-skin (SSD) distance during mobile radiography may not be less than ______ inches. | 12 |
| Mobile radiography produces some of the ________ _________ radiation exposure for radiographers. | highest occupational |
| Reaching over a sterile field is allowed by: | only sterile team members |
| When using the C-arm in surgery: Sterile technique is unnecessary the C-arm is never angled the C-arm is disinfected and considered sterile the C-arm is covered with a sterile drape | The C-arm is covered with a sterile drape |
| signs of shock include all of the following except: excessive thirst cool, clammy skin diaphoresis vomiting | vomiting |
| In a Reverse Waters (for trauma Facial Bones), which topographical landmark is parallel to the CR so that the CR enters the acanthion? | MML |
| Which 2 of the following will produce a more pronounced heel effect? Large Field Size Short SID Long SID Large anode angle | Large field size Short SID |
| Which two of the following attire is worn by the radiographer when entering a strict isolation room for a mobile radiography examination? cap eye shield gown mask | gown mask |
| Which of the procedures are appropriate for trauma patients? 1. Remove immobilization devices that may cause imaging artifacts 2. move tube and IR, instead of injured part, when possible 3. Perform all AP projections, then all lateral projections. | 2 and 3 |
| What should be done if the sterile field is compromised? | Tell OR staff immediately |
| To keep exposure times to a minimum during mobile radiography, the recommended SID should be _______ inches. | 40 |
| What 2 modifications can the radiographer use to produce a quality mobile radiograph? | Seek assistance from a physician for moving fractured limbs. Angle the CR for tilting of the IR due to patient's weight |
| A trauma patient is complaining of shoulder pain and is unable to move his neck. The patient is immobilized on a backboard with a neck brace but insists on removing the brace for the shoulder x-rays. What should the radiographer do? | Perform the procedure with the immobilization device unless a physician instructs otherwise. |
| What is the central ray orientation for the modified axiolateral hip (clements-nakayama)? | 15 degrees posteriorly |
| How often should the OR imaging equipment be cleaned? | after each case |
| You have a patient in a C-Collar, on a back board and the physician is asking for oblique views of the C-spine. On an AP Axial Oblique (trauma) c-spine, how should you angle your CR to obtain the appropriate image? | CR will have a double angle: 45 degrees lateromedially and 15-20 degrees cephalad |
| For a Trauma AP Chest, where should your CR be directed and what should be done to reduce heart magnification? | Perpendicular to Center of IR, with max SID |
| The radiographer should don new gloves to clean mobile equipment after finishing the examination of an isolation patient. T/F | True |
| Which position is used to demonstrate air-fluid levels in the abdomen on a severely injured patient? | dorsal decubitus position |
| During a mobile or portable exposure, the radiographer should be how far from the patient or part being radiographed? | 6 feet |
| The single most effective means of radiation protection during mobile radiography is: | distance |
| During mobile radiography, the radiographer ideally should be standing at what degree of angle from the primary beam? | 90 degrees |
