Question 2

C) stockinette.
D) cloth drawstring.

Question 7

When using sandbags as an immobilization device,

A) refill any sand that leaks out of the bag before the examination begins.
B) make a note for the radiologist,as the sandbag is radiopaque and may leave an artifact.
C) place the sandbag over the area of interest,so the radiologist knows you used one.

Question 8

When immobilizing neonates and young infants,

A) communication with the patient is vitally important.
B) using a sheet for mummification can prove to be very effective.
C) having a fellow radiographer hold the patient should be your first strategy.
D) patient motion is generally not a concern because the infant is typically sleeping.

Question 9

When tape is used as an immobilization tool with an infant,

A) use liberal amounts of tape to hold the infant tightly.
B) place the tape with the adhesive side in touch with the infant's skin to hold better.
C) wrap the tape around the patient several times to secure tightly.
D) twist the tape so the nonadhesive side is against the infant's skin.

Question 10

When performing a lumbar spine series on an elderly patient,

A) move quickly and deliberately from one position to the next to demonstrate your proficiency.
B) increase the thickness of the radiolucent table pad to improve image quality.
C) provide a wedge sponge,placed under the knees.
D) provide a warm blanket for comfort and remove it for each exposure.

Question 11

Patient immobilization is a critical part of achieving optimum image quality.Even the smallest,undetectable involuntary motion can degrade the final image.Effective methods to reduce the amount of patient motion include

A) giving clear,concise instructions to the patient before the exposure.
B) assessing the amount of patient cooperation you can expect and making adjustments in immobilization.
C) explaining how important it is to hold still during the exposure so that a good image can be obtained.
D) All of the above

Question 12

A) the AP and lateral projections with the cervical collar in place.
B) the lateral projection and then remove the collar.
C) the AP projection and then remove the collar.
D) all spine projections with the collar removed and replaced with a head clamp.

Question 13

When radiographing a patient with severe abdominal trauma and possible hemorrhagic shock,it is important to

A) remove the patient's trousers to prevent artifacts.
B) radiograph the patient through the antishock garment the patient is wearing.
C) slowly remove the air in the antishock garment to decrease its radiolucency.
D) add air to the antishock garment to improve image quality.

Question 14

The ideal patient immobilization device would be

A) robotic and intuitive.
B) elaborate in design and disposable.
C) outlined in radiopaque material to show its presence on the image.
D) radiolucent,durable,and easy to use for the radiographer.

Question 15

An inflatable air splint is used under what circumstances?

A) Severe head and cervical spine injuries
B) Lower extremity trauma
C) Spinal injury
D) Shoulder injuries

Question 16

Establishing a rapport with a patient contributes greatly to a successful immobilization exercise.To establish patient rapport,the imaging professional should

A) explain to the patient how important it is hold still and that you will use restraints to ensure this as part of the exam.
B) pull out all your immobilization tools in front of the patient to show you know what you are doing.
C) gently tell the patient what you need to accomplish and how you would like to move forward with the examination.
D) ask for two or three other technologists to come into the room as you begin the positioning.

Question 17

The Octostop immobilization device is used

A) on adolescents and adults.
B) in conjunction with infant mummification.
C) on infants and children younger than 1 year.
D) for upright imaging studies only.

Question 18

You have received an examination request for a pediatric wrist and hand radiograph.The examination history states that the child caught her hand in a fan.The child's hand shows soft tissue swelling but no cuts or abrasions.The patient is brought to you with her mother,who is quite distraught and upset over her child's injury.As you proceed to image the daughter,how would you effectively handle the parent in this situation?
