AHN 568 UNIT 5 CHEST-RAY
INTERPRETATION EXAM QUESTIONS
AND ANSWERS
This is the usual perspective for chest X-rays, which require the patient to stand
erect, take place in the radiology department, and have the detector at least 6
feet away. - ANSWER PA View
Does the PA view show the patient's front or rear against the x-ray film? -
Answer Front
In the PA view, the x-ray bean traverses the patient.
A) From back to front.
B) From front to back.
C) From right to left.
D) from left to right; ANSWER A: from rear to front.
The PA perspective makes the cardiac silhouette appear larger than in the AP
view. True or False? - ANSWER False: the heart seems larger in the AP view
because it is farther away from the camera and creates a larger shadow.
This view is utilized for patients who are ill and unable to stand during their
chest x-ray.
A) Lateral.
,B) posterior anterior.
C) anterior, posterior.
D) Oblique - ANSWER AP
The AP film has higher magnification and is less sharp because it is done using
a portable machine at the bedside and the beam cannot be more than 6 feet
distant. True or false? - The answer is true.
In comparison to the PA view, the AP view is less crisp and has a higher
magnification. True or False: ANSWER True
In the lateral view, which side is generally against the x-ray film? The right or
the left? - ANSWER Left
The lateral view is important for assessing structures in the lung fields and the
anterior mediastinum. True or False? - The answer is false. The lateral view is
most useful for visualizing things in the posterior mediastinum and retrocardiac
regions.
The optimum view for assessing minor pleural effusions is the
A) AP
B) PA
C) Lateral.
D) oblique, ANSWER lateral view b/c it reveals the deepest elements of the
costophrenic angles that are not evident from the AP or PA views.
With a typical lateral film, a nodule on the right seems larger or smaller than a
nodule of the same size on the left. - ANSWER: greater because it is farther
, away from the film and creates a bigger shadow. (Higher magnification results
in a less sharp image).
When viewing the AP or PA Chest x-ray image, a nodule that shows on the
right is located on the patient.
A) Right.
B) Left.
C) anterior.
D) posterior, ANSWER LEFT
A radiolucent object is very light in color, indicating that it has not been
exposed to X-rays. True or False? - ANSWER False: Radiolucent = black or
very dark = strong X-ray exposure.
The more radiation that strikes the film, the darker the image. True or False -
Answer True, the lungs seem black because air absorbs the least amount of
radiation, therefore radiation passes through the lungs and appears dark on film.
Bone and metal absorb the most radiation, turning black. True or false:
ANSWER False: The more radiation an object absorbs, the whiter it appears.
List the tissue densities in the order of least to greatest.
- Bone
- Air
- soft tissue or water
- fat - ANSWER 1) air (radiolucent - radiation can penetrate)
