When IN RAO the arm that should be raised with palm placed on head should be
-
Right
-
Left
Correct Answer
A. LeftExplanation
The correct answer is left because in the IN RAO (Right Anterior Oblique) position, the arm that should be raised with the palm placed on the head is the left arm. This position is commonly used in medical imaging, particularly in cardiac imaging, to obtain specific views of the heart. By raising the left arm and placing the palm on the head, it helps to move the structures of the chest away from the heart, allowing for clearer visualization of the cardiac anatomy.Rate this question:

This positon requires Grid
-
True
-
False
Correct Answer
A. TrueExplanation
This statement is true because the position mentioned in the question requires the use of a grid. The use of the word "requires" indicates that the grid is necessary for the position, suggesting that it is an essential tool or skill for the job.Rate this question:

The SID is
-
.72in
-
72 ft
-
72cm
-
180cm
Correct Answer
A. 180cmExplanation
The correct answer is 180cm. This is because the question asks for the measurement of the SID, and out of the given options, 180cm is the only one that represents a measurement. The other options represent inches and feet, which are not relevant in this context.Rate this question:

The IR is 1inch from ?
Correct Answer
vertebra prominensExplanation
The IR is positioned 1 inch from the vertebra prominens. This means that when taking an X-ray or other imaging scan, the image receptor (IR) should be placed 1 inch away from the vertebra prominens. The vertebra prominens is the most prominent bony landmark on the back of the neck, specifically the spinous process of the seventh cervical vertebra. Placing the IR at this specific distance ensures accurate and consistent imaging results.Rate this question:

Pt errect rotated 45 degrees with left anterior should against IR is?
-
LAO
-
RAO
-
RPO
-
LPO
Correct Answer
A. LAOExplanation
The patient is positioned with their left anterior shoulder against the image receptor (IR) and rotated 45 degrees. This position is called Left Anterior Oblique (LAO).Rate this question:

Only one lung is needed to be seen in this position
-
True
-
False
Correct Answer
A. FalseExplanation
In this position, both lungs should be visible, not just one. Therefore, the statement is false.Rate this question:

KV range is?
-
70-80
-
.110-1.25
-
110-125
-
11.0-12.5
Correct Answer
A. 110-125Explanation
The kV range refers to the kilovolt range, which is a unit of electrical potential difference. In this case, the correct answer is 110-125, indicating that the kilovolt range falls between 110 and 125.Rate this question:

Correct Answer
A. 14x17Explanation
The correct answer is 14x17 because it is the largest size listed, indicating that it is the standard size for this position.Rate this question:

In an RAO the area of interest and best image provided is for which lung
Correct Answer

The correct answer is left because in a right anterior oblique (RAO) view, the area of interest and the best image provided is for the left lung.Rate this question:
- 17.
Exposure must be taken on 2nd inspiration
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because taking exposure on the 2nd inspiration ensures that the X-ray image captures the lungs at their maximum inflation. This is important for accurate diagnosis and assessment of lung conditions. By waiting for the 2nd inspiration, the radiographer can ensure that the lungs are fully expanded, allowing for better visualization of any abnormalities or pathologies.Rate this question:

Collimation occurs where
-
Pubis
-
Lungs
-
Illiac crest
-
ASLS
Correct Answer
A. LungsExplanation
Collimation refers to the process of limiting the size of the x-ray beam to the area of interest, reducing unnecessary radiation exposure to other parts of the body. In this case, the correct answer is "lungs" because collimation is commonly used in chest x-rays to focus the x-ray beam on the lungs and surrounding structures. By collimating the beam to the lungs, radiation exposure to other areas, such as the pubis, illiac crest, or ASLS, can be minimized.Rate this question:

Colimation happens in the ____
Correct Answer
lungsExplanation
Colimation refers to the process of aligning or focusing a beam of radiation into a narrow, well-defined path. In the context of the question, it is implied that colimation occurs in the lungs. This could be attributed to the fact that the lungs play a crucial role in the respiratory system, where air is drawn in and out through a complex network of bronchial tubes. The narrowing and focusing of the airways within the lungs can be seen as a form of colimation, allowing for efficient airflow and gas exchange.Rate this question:
