Question 1

The technique of wrapping an infant patient in a sheet
A) is known as mummification.
B) is effective for young adults and teenagers.
C) requires the use of a commercially available Velcro-edged sheet design.
D) should be used only with parental approval.

Accepted Answer

This technique is known as mummification, which involves wrapping an infant in a sheet to restrict movement, often used for medical procedures or calming purposes.

Question 2

A patient arrives at the medical imaging department for a facial bones 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
A) remove the cervical collar because it appears to be unnecessary.
B) complete the facial bone images with the collar in place using the positioning flexibility of your equipment.
C) call the emergency department nurse and ask her to remove the cervical collar.
D) immobilize the patient's head and then remove the cervical collar so it's not in the image.

Accepted Answer

The imaging technologist should complete the facial bone images with the collar in place using the positioning flexibility of the equipment. Removing the cervical collar without clearance from the emergency department nurse or a physician could be dangerous, especially if there is an underlying spine or neck injury. Immobilizing the patient's head may also be unnecessary if the patient is able to move and position themselves for the imaging exam with the collar in place. Therefore, completing the exam with the collar in place would be the safest and most appropriate option.

Question 3

Effective techniques to use when radiographing children include
A) showing the child a candy treat they will receive if they cooperate.
B) communicating with the parents exclusively and letting them work with their child.
C) getting down to eye level with the child and establishing rapport.
D) asking a uniformed security officer to be in the room during the exam.

Accepted Answer

Getting down to eye level with the child and establishing rapport is the best choice because it helps to build trust between the child and the radiographer, making it more likely that the child will cooperate and remain still for the exam. Offering a candy treat may work in the short term, but it does not address the underlying fear or anxiety the child may have about the procedure. Communicating exclusively with the parents can exclude the child from the process, making them feel even more scared or uncomfortable. Asking a uniformed security officer to be in the room during the exam may escalate the child's fear and make them feel even more intimidated.

Question 4

All of the following are examples of simple immobilization techniques except
A) wrapping a child in a sheet (mummy wrap).
B) using a positioning sponge.
C) laying a sandbag across the patient's anatomy.
D) using a Velcro strap to stabilize the anatomy.

Accepted Answer

Wrapping a child in a sheet is not a recommended or safe immobilization technique. It can potentially cause suffocation and does not provide proper support. The other options listed are all simple and commonly used immobilization techniques.

Question 5

When using a sheet to "mummify" an infant,the sheet should first be formed into a
A) triangle.
B) square.
C) rolled tube.
D) rectangle the size of pillowcase.

Accepted Answer

A sheet should first be formed into a triangle to properly mummify an infant. This is done by folding the sheet diagonally to form a triangle shape, with the point of the triangle at the top. The infant is then placed on the sheet with their feet pointing towards the bottom corner of the triangle, and the sheet is wrapped snugly around their body, starting with the top corner of the triangle and working downwards. This method ensures that the infant's body is fully wrapped and secure.

Question 6

An effective and simple immobilization tool for stabilizing a child's arms,above and behind the head is a: 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
A) Velcro wrist bracelet.
B) nylon tie wrap.
C) stockinette.
D) cloth drawstring.

Accepted Answer

A stockinette is an effective and simple tool for immobilizing a child's arms above and behind the head, as it can be easily adjusted to fit snugly without causing discomfort or restricting circulation, while also being reusable and easy to clean, making it suitable from a radiation protection standpoint.

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.
D) weigh the sandbag before using it,to ensure it is not too heavy on the patient.

Accepted Answer

It is important to make a note for the radiologist when using sandbags as they are radiopaque and may leave an artifact on the image. This will help the radiologist to distinguish between any anomalies caused by the sandbag and actual pathology or injuries.

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.

Accepted Answer

Mummification using a sheet is a common and effective method for immobilizing neonates and young infants during medical procedures, including radiographic imaging, to ensure their safety and the quality of the diagnostic images. This technique restricts movement without causing harm to the patient.

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.

Accepted Answer

When using tape as an immobilization tool with an infant, the tape should be twisted so that the nonadhesive side is against the infant's skin to prevent skin irritation and damage. It is important to not use excessive amounts of tape as it may cause discomfort or impede circulation. Wrapping the tape around the patient several times may also cause constriction and should be avoided.

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.

Accepted Answer

Providing a wedge sponge placed under the knees is important during a lumbar spine series on an elderly patient to reduce discomfort and improve positioning. Options A, B, and D are not necessary or appropriate actions. Moving quickly and deliberately can compromise image quality and patient safety, increasing the thickness of the table pad may not improve image quality, and providing a warm blanket for each exposure is not necessary and can increase exposure time.

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

Accepted Answer

All of the choices are effective methods to reduce patient motion during imaging. Giving clear instructions, assessing patient cooperation, and emphasizing the importance of stillness all contribute to successful patient immobilization.

Question 12

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

Accepted Answer

The AP and lateral projections of the cervical spine should be completed with the cervical collar in place to maintain spinal stability and prevent potential injury until a spinal injury has been ruled out.

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.

Accepted Answer

Radiographing the patient through the antishock garment is the best choice as it avoids any unnecessary movement of the patient that could worsen the hemorrhagic shock. Removing the trousers or manipulating the antishock garment could cause further harm to the patient. Slowly removing air from the antishock garment or adding air to it will not necessarily improve image quality and could delay treatment.

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.

Accepted Answer

The ideal patient immobilization device should be radiolucent so that it does not interfere with the imaging process. It should also be durable and easy to use for the radiographer. Elaborate and disposable designs are not practical and could be detrimental to patient safety. Robotic devices may be costly and not necessarily better than simpler manual devices. The use of radiopaque materials on the device is not necessary since the positioning device is typically outside the area of interest and can be easily identified by 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

Accepted Answer

Inflatable air splints are commonly used in cases of lower extremity trauma to immobilize and provide support to the injured area. They are not typically used in the other scenarios listed.

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.

Accepted Answer

The best way to establish rapport with a patient is to communicate clearly and respectfully with them, explaining what needs to be done and how you plan to do it. This helps the patient feel more at ease and more willing to cooperate with the imaging professional during the immobilization exercise. The use of restraints should also be explained, but it should be done so in a gentle and reassuring way. Pulling out immobilization tools or asking for multiple technologists to come into the room may actually make the patient feel more anxious, which could negatively impact the success of the exercise.

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.

Accepted Answer

The Octostop immobilization device is specifically designed for infants and children younger than 1 year old to help keep them still during medical imaging studies.

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?
A) Refer to departmental policy on parents in the examination room and use your best experience to deal with the mother,which may include having her leave the room.
B) Ask the mother to hold the child if the child appears to be moving.
C) Simulate the exam on the mother first to show the child how easy it will be and show the child sample images.
D) Delay the examination until the mother has regained her composure.

Accepted Answer

It is important to refer to departmental policy on parents in the examination room and handle the situation professionally. If the policy allows for parents to be present, then explain the procedure to the parent and provide reassurance to both the parent and the child. However, if the parent is too distraught and may hinder the child from remaining still during the exam, it may be necessary to ask the parent to wait outside the room. Ultimately, the safety and comfort of the patient should be the top priority.

Question 19

All of the following are true of the Pigg-O-Stat infant immobilizer except
A) it is radiolucent and produces no image.
B) its design provides for lead protection over the child's gonads.
C) it is made of contour-shaped,clear acrylic restraining forms.
D) the patient can be rotated 360 degrees for various oblique projections.

Accepted Answer

All options are true except A, which is false. The Pigg-O-Stat infant immobilizer is radiopaque, meaning it appears on the radiographic image.

Question 20

To achieve extreme dorsiflexion of the ankle,the most effective immobilization method uses
A) elastic wraps.
B) tape.
C) a draw sheet.
D) Velcro straps.
