    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    A. TRUE
    Explanation
    In a posteroanterior (PA) chest image, the beam penetration is considered adequate when the thoracic vertebrae and posterior ribs are visible through the heart and mediastinal structures. This indicates that the X-ray beam has penetrated through the chest and reached the back of the patient, allowing for a clear view of the structures in the chest. Therefore, the statement is true.

    Explanation
    Both A and B are correct. Unequal distances between the vertebral column and the sternal extremity of the clavicle and unequal length of the posterior ribs right and left of the vertebral column are both indicators of rotation on a PA chest radiograph. These findings suggest that the patient was not positioned correctly during the imaging, resulting in a rotated image.

    Rate this question:

  • 11. 

    Both lungs, from the apices to the costophrenic angles should be included on a PA chest x-ray.

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    A. TRUE
    Explanation
    The statement is true because a PA chest x-ray is a standard radiographic examination that is used to evaluate the lungs. It is important to include both lungs in the image from the apices (the uppermost part of the lungs) to the costophrenic angles (the lowermost part of the lungs where they meet the diaphragm). This ensures that the entire lung fields are visible and any abnormalities or pathologies can be properly assessed.

    Rate this question:

  • 12. 

    On a PA chest with no rotation, which posterior ribs should normally appear longer?

    • A.

      Right side should be longer for each corresponding pair of ribs

    • B.

      Right side should be longer for each corresponding pair of ribs

    • C.

      Each sides should be of equal length for each corresponding pair of ribs

    • D.

      Only the anterior ribs are observed to check for rotation

    Correct Answer
    C. Each sides should be of equal length for each corresponding pair of ribs
    Explanation
    The correct answer is "each sides should be of equal length for each corresponding pair of ribs." On a PA chest X-ray with no rotation, the posterior ribs should appear equal in length on both sides. This is because the X-ray is taken from a straight-on view, allowing for accurate comparison between the two sides of the chest. If one side appears longer than the other, it may indicate a potential abnormality or rotation in the chest.

    Rate this question:

  • 13. 

    On a PA chest, the clavicles should be on the same _____________________.

    • A.

      Longitudinal plane

    • B.

      Vertical plane

    • C.

      Coronal plane

    • D.

      Horizontal plane

    Correct Answer
    D. Horizontal plane
    Explanation
    On a PA chest X-ray, the clavicles should be on the same horizontal plane. This means that they should be at the same level and parallel to the ground. This is important for proper positioning and alignment of the clavicles on the X-ray image, allowing for accurate assessment of any abnormalities or fractures. The other options, such as the longitudinal, vertical, or coronal plane, do not accurately describe the expected position of the clavicles on a PA chest X-ray.

    Rate this question:

  • 14. 

    On an optimal PA chest, the scapulae are barely visible inside the mid-portion of each lung.

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    B. FALSE
    Explanation
    The scapulae should be rotated out of the lung field.

    Rate this question:

  • 15. 

    On a PA chest, the manubrium is superimposed by the T-4, with approximately ______ of the apical lung field visible above the clavicles.

    • A.

      1 inch

    • B.

      2 inches

    • C.

      3 inches

    • D.

      4 inches

    Correct Answer
    A. 1 inch
    Explanation
    On a PA chest X-ray, the manubrium is superimposed by the T-4 vertebra. This means that the T-4 vertebra appears to be directly in front of the manubrium, making it difficult to distinguish between the two structures. However, there is still approximately 1 inch of the apical lung field visible above the clavicles. This means that the top portion of the lungs, which is located above the clavicles, can be seen on the X-ray image.

    Rate this question:

  • 16. 

    On a PA chest, what structure is superimposed over the fourth thoracic vertebra?

    • A.

      Xiphoid tip

    • B.

      Clavicle

    • C.

      Gladiolus

    • D.

      Manubrium

    Correct Answer
    D. Manubrium
    Explanation
    The manubrium is the correct answer because it is the uppermost part of the sternum and is located at the level of the second thoracic vertebra. Therefore, on a PA chest X-ray, the manubrium would be superimposed over the fourth thoracic vertebra, making it the structure that is seen in that position.

    Rate this question:

  • 17. 

    How many anterior ribs should be visible above the diaphragm on a fully aerated PA chest?

    • A.

    Correct Answer
    D. The visibility of the posterior ribs, not anterior, should be observed when checking for complete aeration of the lungs.
  • 18. 

    How many posterior ribs should be visible above the diaphragm on a fully aerated PA chest?

    • A.

      9-10

    • B.

      10-11

    • C.

      11-12

    • D.

      The visibility of the anterior ribs, not posterior, should be observed when checking for complete aeration of the lungs.

    Correct Answer
    B. 10-11
    Explanation
    The question is asking about the number of posterior ribs that should be visible above the diaphragm on a fully aerated PA chest. The correct answer is 10-11. This means that when the lungs are fully aerated, 10-11 posterior ribs should be visible above the diaphragm. It is important to note that the visibility of the anterior ribs, not the posterior ribs, should be observed when checking for complete aeration of the lungs.

    Rate this question:

  • 19. 

    What is the best way to ensure full aeration of the lungs for a PA chest?

    • A.

      Exposure should be made before any full inspiration.

    • B.

      Exposure should be made on the second full inspiration.

    • C.

      Exposure should be made as the patient begins to expire.

    • D.

      The exam should be done supine.

    Correct Answer
    B. Exposure should be made on the second full inspiration.
    Explanation
    To ensure full aeration of the lungs for a PA chest, exposure should be made on the second full inspiration. This means that the X-ray should be taken when the patient has taken two deep breaths in order to maximize the expansion of the lungs and improve visibility of the chest structures. This timing allows for better visualization of any abnormalities or pathologies in the lungs.

    Rate this question:

  • 20. 

    On a left lateral chest position, the _________________ should be at the center of the collimation field a the level of the 8th thoracic vertebra.

    • A.

      Midsagittal plane

    • B.

      Midcoronal plane

    • C.

      Sternal ends of the clavicles

    • D.

      Transverse plane

    Correct Answer
    B. Midcoronal plane
    Explanation
    The midcoronal plane refers to a vertical plane that divides the body into equal front and back halves. In a left lateral chest position, the midcoronal plane should be at the center of the collimation field at the level of the 8th thoracic vertebra. This means that the X-ray beam should be aligned with this plane to capture an accurate image of the chest. The other options, such as the midsagittal plane, sternal ends of the clavicles, and transverse plane, do not accurately describe the correct alignment for a left lateral chest position.

    On a left lateral chest, the CR should enter at the level of ________________.

    • A.

      Vertebral prominens

    • B.

      T-4

    • C.

      T-7

    • D.

      T-8

    • E.

      T-10

    Correct Answer
    D. T-8
    Explanation
    The correct answer is T-8. The question is asking about the level at which the central ray (CR) should enter on a left lateral chest X-ray. The CR refers to the center point of the X-ray beam. In this case, it should enter at the level of T-8, which corresponds to the 8th thoracic vertebra. This is important for obtaining an accurate image of the chest area.

    • C.

      1, 2, and 3

    • D.

      None of these structures should be positioned perpendicular to the IR.

    Correct Answer
    C. 1, 2, and 3
    Explanation
    To avoid rotation when performing a left lateral chest exam, all three structures mentioned should be positioned perpendicular to the IR. The shoulders, posterior ribs, and posterior pelvic wings should be aligned in a way that they are at a 90-degree angle to the image receptor. This ensures that the chest is properly aligned and reduces the chances of any rotational distortion in the X-ray image.

    Rate this question:

  • 26. 

    Alignment of the shoulder, posterior ribs, and pelvic wings is accomplished for a left lateral chest exam by resting a flat hand against the back and then adjusting the patient’s rotation until the hand is positioned perpendicular to the IR. 

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    A. TRUE
    Explanation
    The statement is true because in order to achieve proper alignment for a left lateral chest exam, the shoulder, posterior ribs, and pelvic wings need to be aligned. This is done by resting a flat hand against the patient's back and adjusting their rotation until the hand is perpendicular to the IR (image receptor). This ensures that the image taken will accurately capture the desired area of the chest.

    Explanation
    Performing a left lateral chest X-ray has the advantage of minimizing the heart shadow, which allows for better visualization of the lungs and other structures. Additionally, it allows for superimposition of the hemidiaphragm, which aids in evaluating the diaphragm and detecting abnormalities. However, there is no mention of the patient's comfort as an advantage in the given answer.

    Rate this question:

  • 28. 

    For demonstration of air-fluid levels in cases of possible pleural effusion, images of the chest should be done erect and with a horizontal beam.

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    A. TRUE
    Explanation
    To demonstrate air-fluid levels in cases of possible pleural effusion, it is important to perform chest imaging in an erect position with a horizontal beam. This positioning allows gravity to separate air and fluid, making it easier to visualize any fluid accumulation in the pleural space. An erect position helps to avoid false-negative results that may occur when imaging is done in a supine position. Using a horizontal beam ensures accurate measurement and visualization of the levels of air and fluid in the chest.

  • 31. 

    On a portable or supine AP chest exam, which vertebra should be at the center of the collimation field?

    • A.

      T-4

    • B.

      T-7

    • C.

      T-8

    • D.

      T-10

    Correct Answer
    B. T-7
    Explanation
    On a portable or supine AP chest exam, the vertebra that should be at the center of the collimation field is T-7. This is because T-7 is considered the midpoint of the thoracic spine, and by centering the collimation field on this vertebra, it ensures that the entire thoracic spine is included in the image. This is important for accurately assessing the chest and spine for any abnormalities or injuries.

    Rate this question:

  • 32. 

    A 45-degree angle between the midcoronal plane and the IR describes which position?.

    • A.

      AP lordotic

    • B.

      PA lordotic

    • C.

      Left lateral chest

    • D.

      KUB / supine abdomen

    Correct Answer
    A. AP lordotic
    Explanation
    An AP lordotic position is described by a 45-degree angle between the midcoronal plane and the IR. In this position, the patient is standing upright and leaning back at a 45-degree angle. This position is commonly used to visualize the apices of the lungs and to help separate the clavicles from the lung fields. It is often used to assess for pulmonary tuberculosis or other lung abnormalities.

    The sum of these two angles should be about 45 degrees.

    Rate this question:

  • 34. 

    Superimposition of the lung apices with the _________________ is being avoided by angling the tube for a lordotic chest exam?

    • A.

      Clavicle

    • B.

      Sternum

    • C.

      Superior ribs

    • D.

      T-2 and T-3

    Correct Answer
    A. Clavicle
    Explanation
    The superimposition of the lung apices with the clavicle is being avoided by angling the tube for a lordotic chest exam. This is because the clavicle is a bone located at the top of the chest, and if it overlaps with the lung apices in the X-ray image, it can obscure important details and make it difficult to interpret the results accurately. By angling the tube, the X-ray beam can be directed in a way that minimizes the overlap between the clavicle and the lung apices, resulting in a clearer and more useful image for diagnosis.

    Rate this question:

  • 35. 

    AP lordotic chest exam usually requires ____________ tube angulation.

    • A.

      Caudad

    • B.

      Cephalad

    • C.

      Axiolateral

    • D.

      No

    Correct Answer
    B. Cephalad
    Explanation
    The correct answer is cephalad because AP lordotic chest exams require tube angulation in the cephalad direction. This means that the X-ray tube is angled towards the head of the patient to obtain a better view of the upper lung fields. This angulation helps to separate the clavicles and ribs, reducing the overlapping structures and improving the visibility of the lung tissue.

    In position for a supine abdomen, which anatomical structures should be equal distances from the exam table surface on both sides? 1. shoulders 2. anterosuperior iliac spines 3. knees

    • A.

      1 only

    • B.

      2 only

    • C.

      1 and 2 only

    • D.

      2 and 3 only

    • E.

      1, 2, and 3

    Correct Answer
    C. 1 and 2 only
    Explanation
    In the supine position, the anatomical structures that should be equal distances from the exam table surface on both sides are the shoulders and the anterosuperior iliac spines. This means that when lying on the back, both shoulders and the bony protrusions on the front of the pelvis should be at the same height from the table. The knees are not mentioned as being equal distances from the table surface, so they are not included in the answer.

    Rate this question:

  • 39. 

    Why are the shoulders and anterosuperior iliac spines places at equal distances from the exam table on both sides when performing a supine abdomen?

    • A.

      To increase patient comfort

    • B.

      To minimize motion

    • C.

      To avoid rotation

    • D.

      None of the above

    Correct Answer
    C. To avoid rotation
    Explanation
    The shoulders and anterosuperior iliac spines are placed at equal distances from the exam table on both sides when performing a supine abdomen to avoid rotation. This positioning ensures that the patient's body remains in a stable and neutral position, minimizing the chances of any rotational movement. By avoiding rotation, the healthcare professional can obtain accurate and consistent results during the examination.

    Rate this question:

  • 41. 

    The shoulder and anterosuperior iliac spines should be positioned for an upright abdomen exam in the same way that they are positioned for a supine abdomen exam.  The only difference is that the patient is in an erect position instead of recumbent.

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    A. TRUE
    Explanation
    The statement is true because the positioning of the shoulder and anterosuperior iliac spines remains the same for both upright and supine abdomen exams. The only difference is the patient's position, with the supine exam being done while lying down and the upright exam being done in a standing position.

    To evaluate for pneumothorax air in an erect abdomen exam, the patient should be positioned upright for 5 to 20 minutes before the image is taken. 

    • A.

      TRUE

    • B.

      FALSE

    Correct Answer
    B. FALSE
    Explanation
    The erect abdomen is used to evaluate for intraperitoneal air, not pneumothorax air. Pneumothorax air would be in the pleural spaces of the chest.

    Rate this question:

  • 43. 

    How many minutes should a patient be positioned to allow for air to move from the soft tissues in the abdomen to the diaphragm when performing an erect abdomen?

    • A.

      1-5

    • B.

      5-10

    • C.

      5-20

    • D.

      10-20

    • E.

      It should be performed immediately with no waiting period.

    Correct Answer
    C. 5-20
    Explanation
    During an erect abdomen procedure, it is important to allow air to move from the soft tissues in the abdomen to the diaphragm. This can be achieved by positioning the patient for a certain amount of time. The correct answer suggests that the patient should be positioned for 5-20 minutes. This time frame allows enough time for the air to move and ensures an accurate result during the procedure.

    • E.

      1, 2, 3, 4, and 5

    Correct Answer
    D. 1, 2, 4, and 5 only
    Explanation
    In an upright abdomen radiograph, the structures that should be demonstrated are T-9 (vertebral level), iliac wings (part of the pelvic bones), lateral body soft tissue (to assess for any abnormalities), and right and left hemidiaphragm (to evaluate the position and movement of the diaphragm). The symphysis pubis is not typically included in an upright abdomen radiograph. Therefore, the correct answer is 1, 2, 4, and 5 only.

    Which structure should be seen in the center of the collimation field when evaluating an erect abdomen radiograph?

    • A.

      T-12

    • B.

      L-3

    • C.

      L-4

    • D.

      L4-L5 space

    Correct Answer
    B. L-3
    Explanation
    The structure that should be seen in the center of the collimation field when evaluating an erect abdomen radiograph is the L-3 vertebra. This is because the L-3 vertebra is located in the middle of the lumbar spine and is commonly used as a reference point for assessing the alignment and positioning of the lumbar vertebrae. By ensuring that the L-3 vertebra is centered in the collimation field, radiologists can accurately evaluate the surrounding structures and identify any abnormalities or pathologies.

    Rate this question:

  • 48. 

    L-3 is seen at the center of the collimated field for a _______________ exam.

    • A.

      Upright abdomen

    • B.

      Supine abdomen

    • C.

      Left lateral chest

    • D.

      AP lordotic chest

    Correct Answer
    A. Upright abdomen
    Explanation
    The correct answer is "upright abdomen" because L-3 is a landmark used to identify the level of the third lumbar vertebra. In an upright abdomen exam, the patient is standing or sitting upright, and L-3 would be seen at the center of the collimated field, indicating the correct positioning for the exam.
