Questions
Section 1: Patient Care and Safety (Questions 1-19)
1 During a fluoroscopic-guided lumbar puncture, the fluoroscopy unit is set to continuous mode at 30 pulses per
second. The patient's body habitus requires an increased kVp to maintain image quality. Which of the following
best describes the effect on effective dose to the patient if the technologist increases the tube current (mA)
instead of increasing kVp?
A) Effective dose increases proportionally to the square of the mA change.
B) Effective dose increases linearly with mA, but skin dose increases more than effective dose.
C) Effective dose decreases because higher mA improves image quality and reduces exposure time.
D) Effective dose remains unchanged because kVp is the primary determinant of dose.
Answer: B
Rationale: Increasing mA increases the number of x-ray photons, thereby increasing both skin dose and effective
dose linearly. However, because the beam is not hardened (kVp unchanged), the entrance skin dose rises
disproportionately relative to effective dose due to less penetration. Option A is incorrect because dose is linear
with mA, not square. Option C is false because higher mA increases dose, not decreases. Option D is false because
both kVp and mA affect dose.
2 A patient with a known allergy to iodinated contrast is scheduled for an ERCP. The interventionalist requests
use of carbon dioxide (CO2) as an alternative contrast agent. Which of the following is a primary safety
advantage of CO2 over iodinated contrast in this setting?
A) CO2 provides superior mucosal detail compared to iodinated contrast.
B) CO2 is non-allergenic and rapidly absorbed, eliminating risk of anaphylaxis.
C) CO2 has higher radiodensity than iodine, requiring lower radiation dose.
D) CO2 is contraindicated in patients with renal impairment, unlike iodinated contrast.
Answer: B
Rationale: CO2 is a negative contrast agent that is non-allergenic and highly soluble in blood, so it is rapidly
absorbed and excreted, posing no risk of allergic reaction. Option A is false: CO2 provides less mucosal detail than
positive contrast. Option C is false: CO2 is less radiodense, often requiring higher dose. Option D is false: CO2 is
preferred in renal impairment; iodinated contrast is nephrotoxic.
3 A technologist notices that the fluoroscopy table is not moving smoothly during a procedure. Upon inspection,
the table's electromagnetic locks are intermittently failing. Which of the following is the most appropriate
immediate action to ensure patient safety?
A) Continue the procedure using manual table positioning only, and report the issue after the exam.
B) Stop the procedure immediately, remove the patient, and call for equipment service.
C) Apply a temporary mechanical brake using a wedge under the table to secure position.
D) Increase the fluoroscopic dose to compensate for potential patient motion due to table instability.
,Answer: B
Rationale: Intermittent failure of electromagnetic locks poses a risk of uncontrolled table movement, which could
cause patient injury or incorrect positioning. The safest action is to stop the procedure and have the equipment
serviced before further use. Option A is unsafe because manual positioning may not prevent sudden movement.
Option C is not a standard safety practice and could damage equipment. Option D increases radiation risk without
addressing the mechanical hazard.
4 During a fluoroscopic barium enema, the patient suddenly develops respiratory distress, urticaria, and
hypotension. The radiologist suspects an anaphylactic reaction. Which of the following is the first-line
pharmacologic intervention in this scenario?
A) Intravenous diphenhydramine 50 mg
B) Intramuscular epinephrine 0.3 mg (1:1000)
C) Intravenous methylprednisolone 125 mg
D) Subcutaneous epinephrine 0.3 mg (1:1000)
Answer: B
Rationale: Intramuscular epinephrine (1:1000) is the first-line treatment for anaphylaxis due to rapid onset of action
and vasoconstrictive effects. Option A (diphenhydramine) is a second-line antihistamine. Option C (steroid) is used
for delayed reactions. Option D (subcutaneous) has slower absorption and is not preferred in acute anaphylaxis.
5 A patient undergoing a fluoroscopic-guided central line placement develops a sudden onset of dyspnea,
hypoxia, and hypotension. The fluoroscopy image shows the catheter tip in the superior vena cava, but the
patient is in Trendelenburg position. Which of the following is the most likely cause of the patient's symptoms?
A) Air embolism due to open catheter hub during insertion
B) Vasovagal response to catheter manipulation
C) Pneumothorax from inadvertent pleural puncture
D) Contrast extravasation into the mediastinum
Answer: A
Rationale: The Trendelenburg position increases venous pressure in the head and neck, but if the catheter hub was
open to air during insertion, air can be drawn into the venous system, causing air embolism. Symptoms of air
embolism include dyspnea, hypoxia, and hypotension. Option B (vasovagal) typically presents with bradycardia,
not hypoxia. Option C (pneumothorax) would show lung collapse on fluoroscopy. Option D (contrast
extravasation) would cause local swelling, not systemic hypoxia.
6 A fluoroscopy unit is equipped with a last-image-hold feature. During a lengthy interventional procedure, the
technologist uses this feature to review images instead of continuous fluoroscopy. Which of the following best
describes the rationale for this practice?
A) It reduces patient radiation dose by eliminating the need for spot images.
B) It allows the radiologist to manipulate the image without additional radiation.
C) It provides a permanent record of the procedure for documentation.
D) It improves temporal resolution compared to pulsed fluoroscopy.
Answer: B
Rationale: Last-image-hold captures the most recent fluoroscopic frame and displays it without further radiation,
enabling review and planning without exposing the patient. Option A is incorrect because spot images may still be
needed for diagnostic quality. Option C is partially true but not the primary rationale; the image is not necessarily
stored permanently. Option D is false: last-image-hold does not affect temporal resolution.
,7 A patient with a history of severe claustrophobia is scheduled for a fluoroscopic upper GI series. The patient
refuses to drink the barium suspension due to anxiety. Which of the following actions is most appropriate for
the technologist to take?
A) Proceed with the exam using a water-soluble contrast agent instead.
B) Explain the necessity of the exam and encourage the patient to drink the barium.
C) Cancel the procedure and refer the patient for an MRI.
D) Administer a mild sedative as per institutional protocol after consulting the radiologist.
Answer: D
Rationale: Patient refusal due to anxiety may be managed with sedation under medical supervision, provided
institutional protocols are followed. Option A (water-soluble contrast) does not address the anxiety and may not be
appropriate for the study. Option B (encouragement) may be insufficient. Option C (cancel) is premature without
attempting sedation. The technologist should consult the radiologist for sedation orders.
8 During a fluoroscopic procedure, the technologist observes that the cumulative air kerma at the reference point
has reached 2 Gy. The patient is not pregnant and has no prior radiation exposure. According to current
radiation safety guidelines, which of the following actions is required?
A) Immediately terminate the procedure to prevent skin injury.
B) Document the dose in the patient's record and inform the radiologist.
C) Reduce the pulse rate to 7.5 pulses per second for the remainder of the case.
D) Apply a patient skin dose monitoring badge and continue.
Answer: B
Rationale: A cumulative air kerma of 2 Gy approaches the threshold for potential skin effects (typically 2 Gy for
transient erythema). The technologist should document the dose and notify the radiologist to consider dose
management strategies. Option A (termination) is not mandatory unless clinically indicated. Option C (pulse
reduction) is a dose-saving technique but not specifically required by guidelines. Option D (skin badge) is not
standard practice; patient dose monitoring is typically done via the unit's dose display.
9 A patient with a known latex allergy is scheduled for a fluoroscopic-guided biopsy. The procedure tray includes
a latex-containing drape. Which of the following is the most appropriate action to prevent an allergic reaction?
A) Use a non-latex drape and remove all latex-containing items from the procedure room.
B) Pre-medicate the patient with diphenhydramine and proceed with the latex drape.
C) Apply a barrier cream to the patient's skin under the latex drape.
D) Proceed but monitor the patient closely for signs of anaphylaxis.
Answer: A
Rationale: The standard of care for patients with known latex allergy is to create a latex-free environment, including
using non-latex gloves, drapes, and equipment. Option B (pre-medication) is not reliable and does not eliminate the
allergen. Option C (barrier cream) is ineffective. Option D (monitoring) is insufficient because even minimal
exposure can trigger severe reactions.
10 A fluoroscopy technologist is asked to perform a procedure on a patient who is unable to provide informed
consent due to altered mental status. The referring physician states that the procedure is urgent but not
emergent. Which of the following is the most appropriate legal and ethical course of action?
A) Proceed with the procedure as the physician has deemed it necessary.
B) Obtain consent from the patient's next of kin or legal guardian.
C) Delay the procedure until the patient regains capacity to consent.
D) Have the radiologist sign a waiver of consent.
, Answer: B
Rationale: In non-emergent situations, consent must be obtained from a legally authorized representative (next of
kin or guardian). Option A violates patient autonomy. Option C (delay) may be appropriate if the patient's capacity
is expected to return, but the question states urgency, so delay may not be safe. Option D (waiver) is not standard;
consent is required except in true emergencies where delay would cause harm.
11 During a fluoroscopic procedure, a patient inadvertently receives a skin dose exceeding 2 Gy. According to
current radiation safety guidelines, which of the following actions is most critical for the technologist to take
immediately after the procedure?
A) Document the dose in the patient's record and schedule a follow-up appointment for skin assessment within
2-4 weeks.
B) Advise the patient to apply topical corticosteroids to the exposed area to prevent erythema.
C) Reduce the pulse rate and frame rate for subsequent procedures to avoid similar occurrences.
D) Report the incident to the radiation safety officer only if the patient develops visible skin changes.
Answer: A
Rationale: The correct answer is A. Per the Joint Commission and ACR guidelines, any skin dose >2 Gy should be
documented, and the patient should be followed up for potential deterministic effects like erythema. Option B is
premature; topical steroids are not recommended prophylactically. Option C addresses future procedures but not
immediate patient care. Option D is incorrect because reporting is required regardless of visible changes.
12 A patient undergoing an ERCP develops sudden dyspnea and hypotension. The technologist suspects an
adverse reaction to intravenous contrast media. Which of the following is the most appropriate initial
intervention?
A) Administer diphenhydramine 50 mg intramuscularly and monitor vital signs.
B) Place the patient in the Trendelenburg position and administer high-flow oxygen via a non-rebreather mask.
C) Immediately stop the contrast injection, assess airway and breathing, and activate the emergency response
team.
D) Increase the rate of intravenous fluids to 500 mL bolus and administer epinephrine 0.3 mg intramuscularly.
Answer: C
Rationale: The correct answer is C. In a suspected contrast reaction with hypotension and dyspnea, the first priority
is to stop the offending agent and perform a primary assessment (ABCs) while calling for help. Option A
(diphenhydramine) is not first-line for severe reactions. Option B (Trendelenburg) may be used but only after
ensuring airway stability, and oxygen alone is insufficient. Option D (epinephrine) may be indicated for
anaphylaxis but should be given after assessment and activation of emergency response.
13 A patient with a known history of anaphylaxis to iodinated contrast media requires a fluoroscopic procedure.
Premedication is ordered. Which of the following regimens is consistent with the latest ACR Manual on
Contrast Media guidelines?
A) Prednisone 50 mg orally 13 hours, 7 hours, and 1 hour prior to the procedure, plus diphenhydramine 50 mg
orally 1 hour prior.
B) Methylprednisolone 40 mg intramuscularly 12 hours and 2 hours prior, plus famotidine 20 mg intravenously 1
hour prior.
C) Prednisone 50 mg orally 12 hours and 2 hours prior, plus diphenhydramine 50 mg intramuscularly 30 minutes
prior.
D) Hydrocortisone 200 mg intravenously 4 hours prior, plus loratadine 10 mg orally 1 hour prior.
Answer: A
Rationale: The correct answer is A. The ACR recommends a 13-, 7-, and 1-hour prednisone regimen (50 mg each)
