Question 1

True or false

Patients with unequal limb lengths may require quarterly X-rays.

Answer 1

FALSE - may require YEARLY radiographic examinations
p. 2 Merrill’s 2
Read page 2

Question 2

True or false

A grid in the table or vertical Bucky is usually a higher ratio then the one used for mobile radiography. Therefore the contrast within the X-ray room would be improved.

Answer 2

True p. 28 Merrill’s 2

Question 3

When taking radiographs to localize a penetrating object such as metal or glass object what should be included on the image?

Answer 3

The entrance OR exit wound OR BOTH, should be marked with a radiopaque marker visible on all projections
Two 90 degree images should be taken

P. 28 in Merrill’s 2

Question 4

True or false

In an emergency department for a patient in a nearby stretcher…if they are less than 6 feet away from the X-ray tube appropriate shielding should be provided?

Answer 4

True

P. 29 Merrill’s 2

Question 5

TRUE/FALSE

Adhesive tape should be avoided for elderly people because it can be irritating and can easily tear the skin.

Answer 5

TRUE

Question 6

TRUE/FALSE

A decubitus ulcer can develop within 1-2 hours.

Answer 6

TRUE

Merrill’s 3 - p. 225

Question 7

TRUE OR FALSE

Only the type not the amount of contrast media is varied when performing radiographic procedures on the elderly patient?

Answer 7

FALSE
Only the AMOUNT NOT THE TYPE is varied.
Merrill’s p. 227

Question 8

What may be compromised when doing in AP sitting chest as opposed to a PA standing?

Answer 8

Comparison of chest x-rays may be compromised
hyperkyphosis can result in lung apices being obscured
Abdomen may obscure lung bases
There importance of inspiration must be instructed!
Merrill’s 3 - p. 227

Question 9

Which areas are most common for compression fractures?

Answer 9

Thoracic and lumbar spine

Merrill’s 3 p. 228

Question 10

TRUE OR FALSE
Regarding pelvis/hip
If the indication is trauma, the radiographyer should NOT attempt to rotate the limbs?

Answer 10

TRUE

Merrill’s 3 p. 228

Question 11

TRUE OR FALSE

Osteoarthritis, osteoporosis contribute to hip pathologies (ex. fractures)

Answer 11

TRUE

Merrill’s 3 p. 228

Question 12

How should technique factors be altered when patient history indicates emphysema?

Answer 12

Lower kV

p. 230 Merrills 3

Question 13

TRUE OR FALSE
The radiographer should never move a limb that has been operated on or is broken unless the nurse, the physician or sometimes the patient grants them permission.

Answer 13

TRUE

Merrills 3 - p. 241

Question 14

TRUE OR FALSE
A grid must be used for all mobile coputer radiography chest examinations if the exposure technique is more than 100 kVp?

Answer 14

FALSE
If more than 90 kVP

Merrills 3 p. 242

Question 15

TRUE OR FALSE
If the shadows of the shulders is thrown far above the upper edge of the IR when performing a mobile chest xray, the angle of the tube must be corrected?

Answer 15

TRUE

Merrill’s 3 p. 243

Question 16

Where is the central ray directed for an AP chest?

Answer 16

7.6 cm below jugular notch (at level of T7)

Question 17

When performing a mobile femur x-ray over which area should the cathode be placed?

Answer 17

Proximal femur

p. 252 Merrills 3

Question 18

TRUE OR FALSE
Cervical c-spine x-ray : The ensure that the lower cervical verbrae are fully penetrated, the kVp must be set to penetrate the C7 area.

Answer 18

TRUE

p. 257 Merrill’s 3

Question 19

TRUE OR FALSE
When performing and chest/abdomen on a neonate with an endotracheal tube the radiographer should keep the head and neck of the infant straight so that the anatomy in the upper chest and airway is accurately visualized.
If false, why?

Answer 19

FALSE
Straightening the head of a neonatal infant in the supine position can inadvertently advance an endotracheal tube too far into the trachea. Therefore it is sometines more imporant to leave the head of an intubated neonatal patient rotated in the position in which the infant routinely lies

Merrills 3 p. 260

Question 20

TRUE OR FALSE

Up to 10000 microbial particles can be shed from the skin per minute

Answer 20

TRUE
Therefore nonsterile team members should NOT reach over a steril field. A sterile cover should be in place before moving in equipment (in OR) for example
p. 268 - Merrills 3

Question 21

TRUE OR FALSE
Sterile gowns are considered sterile in front from the shoulder to the level of the sterile field and at the sleeves from the elbow to the cuff.

Answer 21

TRUE

Merrills 3 p. 271

Question 22

TRUE OR FALSE
When positioning an IR under the OR table the radiographer should not lift the sterile drapes above table level because this would compromise the sterile field.

Answer 22

TRUE

Merrills 3 p. 271

Question 23

TRUE/FALSE

For digits : If joint injury is suspected AP is recommended instead of PA projection.

Answer 23

TRUE

Question 24

Patient comes into the ER and nurse records a heart rate of 40 BPM. What pathological process does this indicate?

Answer 24

Bradycardia

What is the normal beats per minute of a healthy adult?

Question 25

Pt comes to x-ray, pt history indicates “tachypnea”. What does this indicate?

Answer 25

Respiratory rate is regular but fast (more than 20 breaths/min)
What is the normal respiratory rate for normal adult?

May cause tachycardia (rapid pulse)

What is the normal pulse for a healthy adult?
