III. should be knowledgeable and well prepared

A)I and II
B)II and III
C)I and III
D)I, II, and III

Answer 1

II and III

Question 2

It is not necessary to keep resuscitative supplies in the computed tomography room.

Answer 2

False

Question 3

For older infants and toddlers, oral or rectal chloral hydrate is the most commonly used drug.

Answer 3

True

Question 4

Computed tomography remains the primary screening modality for the abdomen and pelvis in pediatric patients.

Question 5

Characterization of fractures and congenital abnormalities of the skeletal system are not well visualized by computed tomography.

Question 6

Computed tomography is the modality of choice for examinations of the abdomen after blunt injury or high-speed trauma.

Question 7

Any syndrome or condition with a respiratory risk should be recorded and brought to the attention of the radiologist before sedation is given.

Question 8

Advantages of multidetector computed tomography include all of the following except:

A)better patient tolerance
B)better use of contrast media
C)improved contrast resolution
D)reduced motion artifacts

Question 9

Modification of dose parameters is the most straightforward and important method to reduce dose.

Question 10

Oral contrast does not need to be used in pediatric abdominal and pelvic scans.

Question 11

It is the responsibility of every person involved with pediatric computed tomographic imaging to make sure that diagnostic scans are obtained with the minimum radiation dose.

Question 12

For chest computed tomography, shallow breathing in the child is adequate.

Question 13

Mature cells are the most radiosensitive.

Question 14

When positioning the patient for computed tomography of the brain and face, it is not important to have the head centered in the gantry.

Question 15

Immobilization of the child is essential to ensure patient safety and to provide images free of motion artifacts.

Question 16

Computed tomography is not useful in diagnosing congenital abnormalities such as scoliosis, lesions of the vertebral bodies, and osteomyelitis.

Question 17

Successful computed tomographic angiography in children requires optimization of scan technique and contrast administration.

Question 18

The parents are usually an important ally of the technologist and should be included whenever possible.

Question 19

Toys, books, and puzzles are a welcome diversion for the child.

Question 20

The principal duty of the technologist is to ensure that the examination is: I. done accurately
II) done quickly
III) done safely

A)I and II
B)II and III
C)I and III
D)I, II, and III

Question 21

Preparation for sedation requires patients to ingest nothing by mouth:

II. 2-4 hours for formula or breast milk
III. 2 hours for clear liquids

A)I and II
B)II and III
C)I and III
D)I, II, and III

Question 22

All sedated patients require continuous monitoring by nursing staff, which includes all of the following except:

A)blood pressure
B)pulse oximetry
C)respiratory rate

D)wear a cover gown

Question 24

The dose of contrast material for children is:

A)2-3 ml/kg
B)3-4 ml/kg
C)4-5 ml/kg
D)5-6 ml/kg

Question 25

Radiation exposure control can be achieved by: I. careful review of all orders
II) coverage limited to the area of interest
III) selection of appropriate scanning parameters

A)I and II
B)II and III
C)I and III
D)I, II, and III

Question 26

All of the following are infections where computed tomography is used in children except:

A)appendicitis
B)diverticulitis
C)pneumonia
D)pyelonephritis

Question 27

Computed tomography can be used to evaluate deformities in the musculoskeletal system including: I. congenital hip dysplasia
II) femoral anteversion
III) leg-length discrepancy

A)I and II
B)II and III
C)I and III
D)I, II, and III

Question 28

To maintain the infant's body temperature, all of the following can be done except:

A)covering the patient's head with a cap
B)have a parent hold the infant during the scan
C)increase the room temperature
D)wrap the infant in a warm blanket

Question 29
