True or false
Patients with unequal limb lengths may require quarterly X-rays.
FALSE - may require YEARLY radiographic examinations

Read page 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.
True p. 28 Merrill’s 2
When taking radiographs to localize a penetrating object such as metal or glass object what should be included on the image?
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
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?
True
P. 29 Merrill’s 2
TRUE/FALSE
Adhesive tape should be avoided for elderly people because it can be irritating and can easily tear the skin.
TRUE
Merrill’s 3 - p. 225
TRUE/FALSE
A decubitus ulcer can develop within 1-2 hours.
TRUE
Merrill’s 3 - p. 225
TRUE OR FALSE
Only the type not the amount of contrast media is varied when performing radiographic procedures on the elderly patient?
FALSE
Only the AMOUNT NOT THE TYPE is varied.
Merrill’s p. 227
What may be compromised when doing in AP sitting chest as opposed to a PA standing?
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
Which areas are most common for compression fractures?
Thoracic and lumbar spine
Merrill’s 3 p. 228
TRUE OR FALSE
Regarding pelvis/hip
If the indication is trauma, the radiographyer should NOT attempt to rotate the limbs?
TRUE
Merrill’s 3 p. 228
TRUE OR FALSE
Osteoarthritis, osteoporosis contribute to hip pathologies (ex. fractures)
TRUE
Merrill’s 3 p. 228
How should technique factors be altered when patient history indicates emphysema?
Lower kV
p. 230 Merrills 3
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.
TRUE
Merrills 3 - p. 241
TRUE OR FALSE
A grid must be used for all mobile coputer radiography chest examinations if the exposure technique is more than 100 kVp?
FALSE
If more than 90 kVP
Merrills 3 p. 242
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?
TRUE
Merrill’s 3 p. 243
Where is the central ray directed for an AP chest?
7.6 cm below jugular notch (at level of T7)
When performing a mobile femur x-ray over which area should the cathode be placed?
Proximal femur
p. 252 Merrills 3
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.
TRUE
p. 257 Merrill’s 3
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?
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
TRUE OR FALSE
Up to 10000 microbial particles can be shed from the skin per minute
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
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.
TRUE
Merrills 3 p. 271
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.
TRUE
Merrills 3 p. 271
TRUE/FALSE
For digits : If joint injury is suspected AP is recommended instead of PA projection.
TRUE
Patient comes into the ER and nurse records a heart rate of 40 BPM. What pathological process does this indicate?
Bradycardia
What is the normal beats per minute of a healthy adult?
Pt comes to x-ray, pt history indicates “tachypnea”. What does this indicate?
Respiratory rate is regular but fast (more than 20 breaths/min)
What is the normal respiratory rate for normal adult?
Pt comes to ER with following symptoms : pain, anger, fear, fever. How may this affect the heart?
May cause tachycardia (rapid pulse)
What is the normal pulse for a healthy adult?
What affects scatter?
Patient thickness, field size, high Kvp
