Approximately how much of an increase in kVp is required in order to double density?(227-How to control radiographic density using the prime exposure factors)
-
15 percent.
-
20 percent.
-
10 percent.
-
25 percent.
Correct Answer
A. 15 percent.Explanation
An increase in kVp affects the overall exposure of the image, including the density. Doubling the density requires doubling the exposure, which can be achieved by increasing the kVp by a certain percentage. In this case, a 15 percent increase in kVp is sufficient to double the density. Increasing the kVp by 20 percent would likely result in an overexposed image with higher density than desired. Similarly, increasing the kVp by 10 percent would not be enough to double the density, and a 25 percent increase would likely result in an overexposed image with even higher density.Rate this question:

-
Off-angle alignment.
-
Upside down focused grid.
Correct Answer
A. Upside down focused grid.Explanation
When a grid is upside down and focused, it results in a loss of density on both lateral borders of the film. This means that the grid is not aligned properly with the x-ray beam, causing the grid lines to be misaligned with the direction of the x-rays. As a result, the grid fails to effectively absorb scatter radiation and reduces image contrast. This problem can be identified by the presence of decreased density on the lateral borders of the radiographic image.Rate this question:

-
Decrease SID and decrease OID
-
Increase SID and increase OID
-
Increase SID and decrease OID
-
Decrease SID and increase OID
Correct Answer
A. Increase SID and decrease OIDExplanation
To reduce magnification of projected parts, a radiologic technologist should increase the Source-to-Image Distance (SID) and decrease the Object-to-Image Distance (OID). Increasing the SID means moving the x-ray tube further away from the patient, which reduces the magnification effect. Decreasing the OID means bringing the object (patient) closer to the image receptor, which also reduces magnification. Therefore, increasing the SID and decreasing the OID will help minimize the magnification of projected parts.Rate this question:

Where do the collateral ligaments attach to the femur?(409-Osteology of the knee and patella)
-
Intercondyloid eminences.
-
Intercondyloid fossa.
-
Condyles.
-
Epicondyles.
Correct Answer
A. Epicondyles.Explanation
The collateral ligaments of the knee attach to the epicondyles of the femur. The epicondyles are bony projections located on the distal end of the femur, just above the condyles. These ligaments, namely the medial collateral ligament (MCL) and the lateral collateral ligament (LCL), provide stability to the knee joint by connecting the femur to the tibia and preventing excessive side-to-side movement.Rate this question:

The upper portion of the innominate bone is formed by the_______. (411-Osteology of the innominate bones and pelvis)
-
Ischium.
-
Ilium.
-
Acetabulum.
-
Pubis.
Correct Answer
A. Ilium.Explanation
The correct answer is ilium. The innominate bone, also known as the hip bone, is composed of three parts: the ilium, ischium, and pubis. The upper portion of the innominate bone is formed by the ilium, which is the largest and most superiorly positioned of the three parts. The ischium forms the lower and posterior portion, while the pubis forms the lower and anterior portion. The acetabulum is a cup-shaped socket on the lateral surface of the innominate bone, which serves as the point of articulation with the femur to form the hip joint.Rate this question:

The sacrum is formed from______. (412-Osteology of the sacrum and coccyx)
-
Five typical vertebrae.
-
Four typical vertebrae.
-
Four atypical vertebrae.
-
Five atypical vertebrae.
Correct Answer
A. Five atypical vertebrae.Explanation
The sacrum is a triangular bone located at the base of the spine, between the two hip bones. It is formed from five fused vertebrae, which are considered atypical because they have unique characteristics compared to the typical vertebrae found in the rest of the spine. These atypical vertebrae have larger size, thicker bodies, and fused transverse processes, among other distinctive features. Therefore, the correct answer is "five atypical vertebrae."Rate this question:

Which carpal bone has a hook-like process rising from its anterior surface?(413-Osteology of the fingers, hand and wrist)
-
Lesser multangular.
-
Hamate.
-
Lunate.
-
Capitate.
Correct Answer
A. Hamate.Explanation
The carpal bone that has a hook-like process rising from its anterior surface is the hamate. This hook-like process is called the hamulus, and it serves as an attachment point for various ligaments and tendons in the hand and wrist. The hamate bone is located on the medial side of the wrist, and its unique structure makes it easily identifiable.Rate this question:

Which bony structures are located on the proximal portion of the radius?(414-Osteology of the forearm)
-
Base and ulnar notch.
-
Neck and radial notch.
-
Ulnar notch and capitulum.
-
Head and radial tuberosity.
Correct Answer
A. Head and radial tuberosity.Explanation
The correct answer is "Head and radial tuberosity." The head of the radius is located on the proximal portion of the bone and articulates with the capitulum of the humerus. The radial tuberosity is also located on the proximal portion of the radius and serves as an attachment site for the biceps brachii muscle.Rate this question:
