Question 1

An inflatable air splint is used under what circumstances?

Accepted Answer

An inflation or air splint is an inflatable plastic cuff that is slipped over the affected limb and inflated to provide stability for transport by the emergency team.

Question 2

When using a sheet to "mummify" an infant,the sheet should first be formed into a

Accepted Answer

One of the most effective,simple,inexpensive,and reliable methods of restraining or immobilizing a child is a mummy wrap.Basically,the child is wrapped in a triangular-shaped sheet,which effectively limits the movement of the extremities and also gives the technique its name.

Question 3

When obtaining cervical spine images on a patient with a cervical collar,complete

Accepted Answer

All projections should be taken with the cervical collar in place and removed only after the physician has reviewed the radiographic images and determined that it is safe to move the patient without the collar.

Question 4

The technique of wrapping a patient in a sheet

Accepted Answer

One of the simplest,most inexpensive,and reliable methods of restraining or immobilization is a mummy wrap.It is best suited for pediatric patients when other methods are viewed as ineffective.

Question 5

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

Accepted Answer

When tape is used,it should be twisted where it comes in contact with the skin so that the nonadhesive side is in contact with the skin.Another technique to protect the skin is to place a gauze pad between the skin and the tape.

Question 6

When immobilizing neonates and young infants,

Accepted Answer

One of the most effective,simple,inexpensive,and reliable methods of restraining or immobilizing a child is a mummy wrap.Although this method can be used on children 4 or 5 years of age,it is beneficial for children who are still too young to understand cooperation.

Question 7

Patient immobilization methods contribute significantly to a patient's x-ray exposure.The desirable features of an immobilization device,from a radiation protection standpoint,would be

Accepted Answer

When immobilization techniques are discussed,the effect of motion and positioning inaccuracy on the diagnostic quality of the procedure is important to understand.Essential features of immobilization devices include radiolucency,lead protection,positioning flexibility,and a sufficient degree of restraint.

Question 8

A patient arrives at the medical imaging department for a skull series after being hit in the head by a softball.The patient comes to you with a cervical collar,but it is apparent that the collar may not be needed because the patient is turning his head to converse with you as the examination starts.A professional imaging technologist would

Accepted Answer

Use the positioning versatility of the equipment design to minimize patient movement.All projections should be taken with the cervical collar in place and removed only after the physician has reviewed the radiographic images and determined that it is safe to move the patient without the collar.

Question 9

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

Accepted Answer

One of the most effective means of reducing motion on images is good communication with the patient.Also required is an accurate assessment of the degree of cooperation the patient is able to provide.

Question 10

All of the following are examples of simple immobilization techniques EXCEPT

Accepted Answer

The simplest immobilization techniques involve the use of a positioning sponge to support the anatomic area of interest or gently laying a sandbag across a patient's forearm to minimize shaking caused by patient anxiety.A "mummy wrap" is regarded as a more complex technique.

Question 11

To achieve extreme dorsiflexion of the ankle,the most effective immobilization method uses

Accepted Answer

Velcro strap restraints are designed to be attached easily to the radiography table and can be adjusted to cover any part of the body,such as the chest,abdomen,or legs.Adjustments to the straps can achieve the desired amount of restraint to hold a patient in position.

Question 12

The ideal patient immobilization device would be

Accepted Answer

Essential features of immobilization devices include radiolucency,positioning flexibility,and ease of use as well as a sufficient degree of restraint.

Question 13

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?

Accepted Answer

A preliminary consideration for pediatric radiography is how to manage parents while the examination is being performed.Parents in the room during the examination may be helpful in comforting the child but also may get in the way of examination success.With the use of department protocol and experience,the radiographer must decide what option will yield the best results.

Question 14

All of the following are true of the Pigg-O-Stat infant immobilizer EXCEPT

Accepted Answer

The Pigg-O-Stat is useful for upright chest and abdominal radiographic examinations.It is not designed for recumbent positioning.

Question 15

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

Accepted Answer

An antishock garment is a pair of inflatable trousers applied to a trauma patient.This garment is used in instances in which the patient has sustained trauma to the abdomen,pelvis,or lower extremities and internal hemorrhage is suggested.Because the trousers are radiolucent,they can be left in place while the examination is being performed.

Question 16

When performing a lumbar spine series on an elderly patient,

Accepted Answer

Bending the hips and knees slightly between exposures offers considerable relief to some geriatric patients.A sponge or radiolucent pad beneath the patient's knees can greatly reduce strain on the patient's back and increase the patient's ability to cooperate during the examination.

Question 17

Effective techniques to use when radiographing children include

Accepted Answer

Kindness,patience,honesty,and understanding are best conveyed to children literally on their level by dropping to one knee to talk with the children face to face.Other approaches can be intimidating to pediatric patients.

Question 18

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

Accepted Answer

An accurate assessment of the degree of cooperation the patient is able to provide greatly contributes to successful examinations.Using a calm,confident approach while explaining the methods for completing the procedure often elicits greater patient cooperation and establishes professional rapport.

Question 19

When using sandbags as immobilization devices,

Accepted Answer

Sandbags,unlike radiolucent positioning sponges,are radiopaque and require special attention for placement so as not to obscure diagnostic information.If they are projected onto the final image,a note should be made for the radiologist.

Question 20

The Octostop immobilization device is used

Accepted Answer

Only infants and small children up to 1 year of age should be immobilized with the Octostop.It can be used for upright and recumbent positions and takes advantage of Velcro straps.
