Question 1

Moving the foot and toes downward is:

Accepted Answer

Moving the foot and toes downward is called plantar flexion.

Question 2

What is the final step taken before making the exposure during a positioning routine?

Accepted Answer

Ensuring correct gonadal shield placement is the final step taken before making the exposure during a positioning routine. This is done to protect the patient's reproductive organs from unnecessary radiation exposure.

Question 3

What is the minimal number of projections taken for a study of the femur?

Accepted Answer

Two projections are necessary for a study of the femur; an AP projection and a lateral projection. This allows for a thorough examination of the entire bone and ensures accurate diagnosis.

Question 4

What is the minimal number of projections taken for a study of the right hip?

Accepted Answer

Two projections are needed to study the right hip, typically an anteroposterior (AP) and a lateral projection.

Question 5

A patient is erect with the left side of his chest placed against the image receptor.The central ray enters the right side of the upper chest and exits the left.Which specific position has been performed?

Accepted Answer

In this position, the patient is standing erect with the left side of the chest against the image receptor, and the central ray enters the right side of the upper chest and exits the left. This is a specific type of lateral projection used for imaging the lungs and thoracic structures. The other positions listed do not match the description mentioned.

Question 6

Which of the following radiographic procedures often only requires a single AP projection be taken?

Accepted Answer

A single AP projection is often sufficient for a pelvis radiograph to assess the general structure and alignment.

Question 7

What is the minimal number of projections taken for a postreduction (to realign a fracture) study of the ankle?

Accepted Answer

Two projections are necessary for a postreduction study of the ankle: one view of the mortise and one lateral view. This is to confirm the reduction of the ankle joint and assess for any additional fractures or dislocations. Option A is not enough to fully evaluate the ankle, while options C and D would be unnecessary and increase patient radiation exposure without significant additional diagnostic benefit.

Question 8

A patient enters the emergency department (ED) with a piece of wire in the palm of the hand.What is the minimum number of projections required to be taken for this radiographic study?

Accepted Answer

Two projections are required, including a PA and lateral of the affected hand to confirm the presence and location of the wire in the palm. Additional projections may be taken if needed for further evaluation or treatment planning.

Question 9

The patient's head and neck are hyperextended with the top of the skull directly against the image receptor.The central ray enters just below the chin.Which specific projection has been performed?

Accepted Answer

The submentovertical projection is performed with the patient in a hyperextended position with the top of the skull directly against the image receptor. The central ray enters just below the chin. Acanthioparietal projection involves the central ray entering the top of the skull and Parietoacanthial projection enters the patient's forehead. Verticosubmental is not a common radiographic projection.

Question 10

The opposite term for supination is:

Accepted Answer

Supination refers to the outward rotation of the forearm, so the opposite term would refer to the inward rotation of the forearm, which is pronation. A) Protraction refers to a movement forwards, B) Adduction refers to movement towards the midline of the body, and D) Retraction refers to movement backwards, none of which are opposite to supination.

Question 11

Which of following is NOT one of the evaluation criteria applied in the evaluation of images?

Accepted Answer

Patient condition is not a criteria applied in the evaluation of images. The other three options (anatomy demonstrated, collimation and CR, and exposure criteria) are important factors in evaluating the quality of an imaging study.

Question 12

A dorsoplantar projection would be a radiographic study of:

Accepted Answer

A dorsoplantar projection is a radiographic study of the foot. It is a view that provides a straight-on, top-to-bottom image of the foot, looking at the dorsal (top) surface and the plantar (sole) surface simultaneously. It is commonly used in the evaluation of fractures, dislocations, and other conditions affecting the bones and soft tissues of the foot.

Question 13

A patient is erect facing the x-ray tube and leaning the shoulders backward 20° to 30° toward the IR.The central ray is perpendicular to the IR.What specific position has been performed?

Accepted Answer

This position is known as a lordotic position, which is performed to get a clear view of the upper lobe of the lung by moving the clavicles out of the way. In a lordotic position, the patient stands with their back towards the image receptor, leans backward, and tilts their head and shoulders backward to produce a steep angle between the clavicles and the image receptor. The central ray is perpendicular to the image receptor, which makes the X-ray beam pass through the upper lobe of the lung.

Question 14

What is the minimal number of projections taken for a study of the elbow?

Accepted Answer

The answer of What is the minimal number of projections...

Question 15

Movement in the form of a circle is the definition for:

Accepted Answer

Circumduction involves movement in a circular or conical manner, with the distal end of the limb or appendage moving in a circular direction while the proximal end remains stable. This type of movement is commonly seen in ball-and-socket joints like the shoulder or hip.Rotation involves movement around a fixed axis, while retraction and protraction involve movement in a backward or forward direction, respectively.

Question 16

The top of the foot is placed against the image receptor with the perpendicular central ray entering the sole of the foot.What specific projection has been performed?

Accepted Answer

The plantodorsal projection is performed with the top of the foot placed against the image receptor and the central ray perpendicular to the sole of the foot. This projection is also known as the dorsoplantar projection or the AP projection of the foot. The other options listed are not specific or accurate descriptions of this projection.

Question 17

The patient is lying on her right side on a cart.The anterior surface of the patient is against the image receptor.A horizontal central ray enters the posterior surface and exits the anterior surface of the body.What specific projection/position has been performed?

Accepted Answer

The description matches a right lateral decubitus position, where the patient lies on their right side, and the image is taken horizontally. This position is used to show fluid levels or air accumulation in the body that wouldn't be visible in a standard upright position.

Question 18

The radiographic term projection is defined as:

Accepted Answer

The radiographic term projection refers to the direction or path of the central ray.

Question 19

Which of the following positions is often used to insert a rectal enema tip before a barium enema study?

Accepted Answer

The Modified Sims' position, also known as the left lateral position, is commonly used for inserting a rectal enema tip before a barium enema study. This position allows for easy access to the rectum and prevents the patient from experiencing discomfort during the procedure. The Fowler position is a sitting position and not suitable for this procedure, while the Lithotomy and Trendelenburg positions are used for other types of medical procedures.

Question 20

Which of the following terms is the opposite of ipsilateral?

Accepted Answer

Ipsilateral refers to structures or phenomena occurring on the same side of the body, while contralateral refers to structures or phenomena occurring on the opposite side of the body. Therefore, C (Contralateral) is the opposite of Ipsilateral.
