2. When taking an AP Cervical Open Mouth X-Ray Image, where should the central ray be pointed?

Through the open mouth

Through the tip of the nose

Through the Thyroid Cartilage

Through C4

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.

3. When taking a lateral cervical x-ray image, where should the central ray be pointed and what should the KVP setting be?

Central Ray should be pointed at C4 and the KVP should be set at 80 KVP

Central Ray should be pointed at the Thyroid Process and the KVP should be set at 70 KVP

Central Ray should be pointed at Thyroid Process and the KVP should be set at 80 KVP

Central Ray should be pointed at C4 and the KVP should be set at 70 KVP

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.

4. When taking a Lateral Cervical X-Ray Image, what is the Tube Tilt and Distance?

No Tube Tilt at 40 Inches

15 degree Tube Tilt towards the floor at 72 Inches

No Tube Tilt at 72 Inches

15 Degree Tube Tilt towards the floor at 40 inches

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.

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.

5. When taking an AP Cervical Open Mouth X Ray Image, what is the KVP setting?

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.

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.

6. For the Flexion and Extension images of the Cervical Spine, what is the KVP setting and distance?

80 kvp and 40"

90 kvp and 40"

80 kvp and 72"

90 kvp and 72"

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.

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.

7. Besides the AP Cervical and the Lateral Cervical images, what are the other commonly taken images of the cervical spine?

Posterior Oblique

Anterior Oblique

Flexion and Extension

A and C

All of the above

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.

8. When taking Oblique Cervical x-ray images the body is at ____ degrees, the tube is at ____ degrees, and the central ray is through _____.

15, 45, C4

45, 90, C4

45, 15, C4

15, 45, the Thyroid Process

45, 15, the Thyroid Process

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.

9. When collimating a Cervical Spine X-Ray image, what should the collimation be set to?

Film size or smaller

Slightly larger than the film size

1" in from all sides

2" in from all sides

2" in from width

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.

10. What should the patient's instructions be for a Cervical X-Ray image?

Hold your breath and hold still

Take a deep breath in, push it out, hold it out and hold very still

Take a deep breath in, hold it in, and hold very still

Take a serious of shallow breaths

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.
