RADT 316 Unit 6
| Question | Answer |
|---|---|
| How much rotation and which oblique position are required to best demonstrate the left sternoclavicular joints? | 10-15 degrees; LAO |
| Which aspect of the rib articulates with the thoracic vertebral body? | Head |
| T/F: The degree of rotation for the right anterior oblique (RAO) projection of the sternum is dependent on the size of the thorax cavity. | True |
| Which position is desired for a lower ribs radiograph? | Supine |
| T/F: An erect lateral projection of the sternum requires that the exposure is to be on expiration. | False |
| A radiograph of a lateral projection of the sternum reveals that the patient's ribs are superimposed over the sternum. What needs to be done to correct this problem during the repeat exposure (choose the best practice)? | Ensure patient is not rotated |
| Where is the CR centered for a PA oblique sternum? | Level of T7, 1 inch on elevated side |
| What is the minimum number of ribs that must be demonstrated for a unilateral rib study above the diaphragm? | Nine |
| What is the respiration phase for the PA projection of the upper ribs? | Inspiration |
| Which of the following is the recommended position for optimal demonstration of the upper anterior ribs? | Upright standing and upright seated |
| Which two projections must be taken for an injury to the right anterior, upper ribs? | PA, LAO |
| What is the joint space between the manubrium and body of sternum called? | Sternal angle |
| A patient enters the ED with blunt trauma to the sternum. The patient is in great pain and cannot lie prone on the table or stand erect. Which of the following positioning routines would be best for the sternum examination in this situation | LPO, cross table lateral |
| Which ribs are considered to be true ribs? | 1-7 |
| In the erect adult bony thorax, the posterior or vertebral end of a typical rib is __ higher than or more superior to the anterior portion. | 3-5 inches |
| Which of the following ribs is considered to be a false rib? | 8-12 |
| Why is the RAO sternum preferred to the LAO position? | Puts in heart shadow; homogenous brightness |
| Which of the following is also a reference for level T4-T5? | Sternal angle |
| A radiograph of an RAO projection of the sternum demonstrates obscured the sternum. A half-second exposure time and an orthostatic (breathing) technique were used. Which of the following will produce a more diagnostic image of the sternum? | Increase exposure time to 3-4 seconds |
| Which condition of the sternum is often termed "funnel chest" where there is a depressed sternum? | Pectus excavatum |
| A congenital defect characterized by anterior protrusion of the lower sternum is termed: | Pectus carinatum |
| The jugular notch corresponds to the level of | T2-3 |
| Which of the following structures connects the anterior aspect of the ribs to the sternum? | Costal cartilage |
| The xiphoid process corresponds to the vertebral level of: | T9-10 |
| Where is the CR centered for a PA projection of the sternoclavicular joints? | 3 inches distal to C7 |
| An ambulatory patient enters the emergency department (ED) with a possible injury to the right upper posterior ribs. Which of the following positioning routines should be taken to best demonstrate the involved area? | AP, RPO |
| What is the most optimal SID for a lateral sternum? | 60-72 |
| A radiograph of an RAO sternum reveals that it is partially superimposed over the spine. What must be done to eliminate this problem during the repeat exposure? | Increase rotation |
| At approximately what age does the xiphoid process become totally ossified? | 40 years |
| Which of the following positions will best demonstrate the anterior portion of the right ribs? | PA, LAO |
| Which of the following landmarks can be palpated to locate the upper margin of the sternum on the obese patient? | Jugular notch |
| In a left posterior oblique, which side of the ribs is demonstrated? | Left |
| In which of the following body habitus is the diaphragm at its highest? | Hypersthenic |
| How much is the body rotated for oblique ribs? | 45 degrees |
| Fracture of adjacent ribs in two or more places with associated pulmonary injury is known as a(n) __ rib injury. | Flail chest |
| Which of the following projections will demonstrate the left SC joint without superimposition over the spine? | LAO |
| What is the centering for below the diaphragm ribs? | Midway between xiphoid tip and lower rib cage |
| T/F: The use of 125 kV is recommended for AP and PA projections of the ribs. | False |
| How does the costal cartilage of the eighth through tenth ribs attach to the sternum? | Attached to costal cartilage of 7th rib |
| Which of the following techniques is most effective in preventing lung markings from obscuring the sternum on an oblique projection? | Orthostatic breathing |
| Which of the following positions will best demonstrate the posterior portion of the left ribs? | AP, LPO |
| What is the amount of movement of the diaphragm between deep inspiration and deep expiration on an average patient? | 1.5 inches |
| Which of the following statements is true about floating ribs? | They do not possess costocartilage |
| A patient with metastatic disease in the ribs comes to radiology following a nuclear medicine scan. The radiologist orders a right, upper posterior rib study. Which of the following positioning factors should be followed for this specific study? | Perform positions erect if patient condition permits; include the RPO position as part of the positioning routine |
| Which of the following is true in regards to a PA oblique right SC joint radiograph? | We visualize the right downside SC joint |
| Which of the following conditions may occur with trauma to the ribs? | Hemothorax |
