CAMRT Anatomy and Positioning Principles Questions and Answers 1 — Questions and Answers
Question 1: Which positioning term describes the patient lying face down on the radiographic table?
- Supine
- Prone (Correct answer)
- Lateral recumbent
- Trendelenburg
Correct answer: Prone
Prone positioning places the patient face down, with the anterior surface of the body against the table.
Question 2: The term 'PA projection' in chest radiography means the x-ray beam travels in which direction?
- Anterior to posterior
- Posterior to anterior (Correct answer)
- Lateral to medial
- Superior to inferior
Correct answer: Posterior to anterior
In a PA projection, the central ray enters the posterior (back) surface and exits the anterior (front) surface toward the image receptor.
Question 3: Which anatomical plane divides the body into equal right and left halves?
- Coronal plane
- Transverse plane
- Midsagittal plane (Correct answer)
- Oblique plane
Correct answer: Midsagittal plane
The midsagittal (median) plane divides the body into equal right and left halves along the midline.
Question 4: When positioning for a lateral lumbar spine radiograph, which structure is used as the centering point?
- T12 vertebra
- L3 vertebra (Correct answer)
- Iliac crest
- ASIS
Correct answer: L3 vertebra
The central ray is directed to L3, located at approximately the level of the iliac crest, as the centering point for lateral lumbar spine projections.
Question 5: The acanthion is a landmark used for which type of radiographic positioning?
- Chest positioning
- Skull and facial bone positioning (Correct answer)
- Lumbar spine positioning
- Pelvis positioning
Correct answer: Skull and facial bone positioning
The acanthion, located at the base of the anterior nasal spine, is a key surface landmark used in skull and facial bone radiographic positioning.
Question 6: Which rotation is used when performing an RPO (right posterior oblique) position?
- Patient rotated with right side up away from table
- Patient rotated with right posterior surface closest to IR (Correct answer)
- Patient lying on right side
- Patient facing right with left side down
Correct answer: Patient rotated with right posterior surface closest to IR
In an RPO position, the patient's right posterior surface is closest to the image receptor, with the body rotated so the right back is down.
