1. A radiographer is preparing to perform a portable chest
radiograph on a patient in an intensive care unit. The patient has
multiple intravenous lines, an endotracheal tube, and a central
venous catheter. Which action should receive the highest priority
before exposure?
A. Increase the kVp to compensate for the patient's supine position
B. Verify the patient's identity, examination, side/site, and carefully
assess the location of tubes and lines
C. Remove all monitoring equipment before positioning
D. Place the patient upright regardless of clinical condition
Answer: B. Verify the patient's identity, examination, side/site, and
carefully assess the location of tubes and lines
Rationale: Correct patient identification and verification of the
examination are fundamental safety requirements. In a critically ill
patient, the radiographer must also recognize the location of tubes,
catheters, and other devices so that positioning does not dislodge them.
Increasing technical factors without assessing the patient is
inappropriate, and monitoring equipment should not simply be
removed.

,2. A patient is suspected of having a pneumothorax. Which
radiographic finding is most characteristic?
A. Increased pulmonary vascular markings peripheral to the pleural line
B. Visible visceral pleural line with absence of peripheral lung markings
C. Bilateral hilar enlargement
D. Diffuse reticulonodular opacities
Answer: B. Visible visceral pleural line with absence of peripheral
lung markings
Rationale: A pneumothorax occurs when air enters the pleural space.
On a radiograph, the visceral pleural line may become visible, with
absent pulmonary vascular markings beyond that line. In an upright
patient, the pleural air may accumulate superiorly; on a supine
radiograph, the deep sulcus sign may be present.
3. During fluoroscopy, the radiologist asks the technologist to reduce
patient radiation dose while maintaining adequate image quality.
Which combination is most appropriate?
A. Increase fluoroscopy time and increase magnification
B. Use pulsed fluoroscopy, appropriate collimation, and minimize
fluoroscopy time
C. Increase the field size and use continuous fluoroscopy
D. Place the image receptor farther from the patient
Answer: B. Use pulsed fluoroscopy, appropriate collimation, and
minimize fluoroscopy time
Rationale: Radiation dose can be reduced by minimizing fluoroscopy
time, using pulsed rather than continuous fluoroscopy when
appropriate, and tightly collimating the beam. Maintaining
appropriate source-to-image geometry also helps optimize dose.

,Magnification and unnecessary field size generally increase radiation
exposure.
4. A patient requires a contrast-enhanced CT examination but
reports a previous mild reaction to iodinated contrast. What is the
most appropriate initial approach?
A. Automatically administer contrast without documentation
B. Determine the nature and severity of the previous reaction and notify
the appropriate clinical team
C. Tell the patient that previous reactions are irrelevant
D. Substitute barium for intravenous iodinated contrast in every situation
Answer: B. Determine the nature and severity of the previous
reaction and notify the appropriate clinical team
Rationale: A previous contrast reaction should be characterized
carefully because the severity and nature of the reaction affect risk
assessment and management. The radiology team should follow the
facility's contrast-reaction policy and physician-directed precautions.
A history of a reaction does not mean that every contrast-enhanced
examination is absolutely prohibited.
5. Which principle is central to radiation protection for
occupationally exposed personnel?
A. Maximum exposure
B. ALARA
C. Radiation accumulation is harmless below a fixed threshold
D. Distance is irrelevant when shielding is available
Answer: B. ALARA
3
, Rationale: ALARA means “as low as reasonably achievable.”
Radiation protection involves minimizing unnecessary exposure while
obtaining diagnostically useful information. Time, distance, and
shielding are fundamental components of radiation protection.
6. A radiographer doubles the distance between the radiation source
and an occupational worker. According to the inverse square law,
the radiation intensity approximately becomes:
A. Twice as great
B. Four times as great
C. One-half as great
D. One-fourth as great
Answer: D. One-fourth as great
Rationale: Radiation intensity from a point source is inversely
proportional to the square of the distance. If distance doubles,
intensity decreases to 1/(2²), or approximately one-fourth of its original
value. This makes increasing distance one of the most effective
methods of reducing occupational exposure.
7. Which interaction between an x-ray photon and matter
contributes most directly to image contrast in diagnostic
radiography?
A. Pair production
B. Compton scattering
C. Photoelectric absorption
D. Nuclear fission
Answer: C. Photoelectric absorption
