When taking a lateral cervical x-ray image, where should the central ray be pointed and what should the KVP setting be?
Correct Answer
A. Central Ray should be pointed at C4 and the KVP should be set at 80 KVP
Explanation
The correct answer is that the central ray should be pointed at C4 and the KVP should be set at 80 KVP. This is the correct technique for taking a lateral cervical x-ray image. The C4 vertebra is the standard landmark for this type of x-ray, as it is located at the level of the larynx. The KVP setting of 80 is appropriate for obtaining clear and detailed images of the cervical spine.

What does ALARA stand for?
Correct Answer
D. None of the above
Explanation
ALARA stands for As Low As Reasonably Achievable. This principle is commonly used in fields involving radiation exposure, such as radiology, nuclear industry, and radiological protection. It aims to minimize radiation doses and releases of radioactive materials by employing all reasonable methods. Therefore, the correct answer from the options provided is:
None of the above.
3.
When collimating a Cervical Spine X-Ray image, what should the collimation be set to?
Correct Answer
A. Film size or smaller
Explanation
When collimating a Cervical Spine X-Ray image, the collimation should be set to film size or smaller. This means that the collimation should be adjusted to match the size of the film being used or even smaller, ensuring that only the necessary area is captured in the X-Ray image. This helps to reduce unnecessary radiation exposure to the patient and improve the overall quality and clarity of the image.
4.
What should the patient's instructions be for a Cervical X-Ray image?
Correct Answer
C. Take a deep breath in, hold it in, and hold very still
Explanation
To obtain a clear and sharp image during a Cervical X-Ray, instructing the patient to take a deep breath in, hold it, and maintain stillness helps minimize motion artifacts. This ensures a high-quality image for accurate diagnosis while providing consistent breathing instructions across the imaging process.
5.
When taking an AP Cervical Open Mouth X-Ray Image, where should the central ray be pointed?
Correct Answer
A. Through the open mouth
Explanation
The central ray should be pointed through the open mouth when taking an AP Cervical Open Mouth X-Ray Image. This is because the purpose of this X-ray is to visualize the cervical spine, specifically the upper cervical vertebrae, and the open mouth position allows for a clear view of these structures. By directing the central ray through the open mouth, the X-ray image will capture the desired area of interest, providing a clear and accurate representation of the cervical spine.
6.
Besides the AP Cervical and the Lateral Cervical images, what are the other commonly taken images of the cervical spine?
Correct Answer
E. All of the above
Explanation
The other commonly taken images of the cervical spine, besides the AP Cervical and the Lateral Cervical images, include the Posterior Oblique, Anterior Oblique, and Flexion and Extension images. These additional images provide different views and angles of the cervical spine, allowing for a more comprehensive evaluation of the area.
7.
When taking Oblique Cervical x-ray images the body is at ____ degrees, the tube is at ____ degrees, and the central ray is through _____.
Correct Answer
C. 45, 15, C4
Explanation
When taking Oblique Cervical x-ray images, the body is positioned at a 45-degree angle, the tube is positioned at a 15-degree angle, and the central ray is directed through the C4 vertebra. This positioning allows for optimal visualization of the cervical spine and surrounding structures.
8.
When taking an AP Cervical Open Mouth X-Ray Image, what is the ideal position for the patient?
Correct Answer
B. Patient should be sitting with her chin tucked in and mouth open as wide as possible.
9.
When taking an AP Cervical Open Mouth X Ray Image, what is the KVP setting?
Correct Answer
80
80 kvp
80 KVP
Explanation
The correct answer is 80, 80 kvp, 80 KVP. The KVP setting refers to the kilovoltage peak, which determines the energy level of the X-ray beam. In an AP Cervical Open Mouth X-ray image, a KVP setting of 80 is commonly used to capture clear and detailed images of the cervical spine.
10.
For the Flexion and Extension images of the Cervical Spine, what is the KVP setting and distance?
Correct Answer
C. 80 kvp and 72"
Explanation
The correct answer is 80 kvp and 72". This means that for the flexion and extension images of the cervical spine, the kilovoltage peak (kvp) setting is 80 and the distance between the X-ray source and the patient is 72 inches.
11.
When taking a Lateral Cervical X-Ray Image, what is the Tube Tilt and Distance?
Correct Answer
C. No Tube Tilt at 72 Inches
Explanation
In a lateral cervical X-ray image, the correct tube tilt and distance is no tube tilt at 72 inches. This means that the X-ray tube should be positioned perpendicular to the floor without any tilt, and the distance between the patient and the X-ray tube should be 72 inches. This positioning allows for a clear and accurate image of the cervical spine without any distortion caused by tube tilt or incorrect distance.
12.
When taking a lateral Cervical x-ray image, which shoulder should be against the Bucky?
Correct Answer
B. Left
Explanation
The standard practice for a neutral lateral cervical spine X-ray is to position the left shoulder against the Bucky. This position helps to obtain a clearer image by aligning the cervical spine parallel to the detector.
