CERTIFIED RADIOLOGY
NURSE CRN PRACTICE
EXAM COMPLETE
Question 1: A vial of diagnostic radiopharmaceutical spills on the �oor. What should the nurse do �rst?
Choices:
1) Dispose of contaminated material in ordinary trash 2) Wipe it up quickly with bare hands 3) Spread the liquid over a larger area to dilute it 4) Restrict access to the area and follow the radiation spill procedure while notifying nuclear medicine or radiation safety personnel Correct Answer: Restrict access to the area and follow the radiation spill procedure while notifying nuclear medicine or radiation safety personnel Explanation: A radioactive spill requires control of the area to prevent spread and unnecessary exposure. Radiation safety procedures guide containment, monitoring, cleanup, and waste disposal.Page 1
Question 2: A critical CT �nding is verbally communicated to the clinical team. Which nursing action supports safe interdisciplinary practice?
Choices:
1) Delete the communication from the record after hando� 2) Assume the message was received and avoid documentation 3) Ensure the critical result communication is documented according to policy and that responsibility for follow-up is clear 4) Tell the patient to interpret the report independently Correct Answer: Ensure the critical result communication is documented according to policy and that responsibility for follow-up is clear Explanation: Reliable critical-result systems require timely communication, documentation, and clear hando� of responsibility. This reduces the risk that urgent �ndings are missed.
Question 3: Before ultrasound-guided central venous catheter placement, which
�nding should the nurse report?
Choices:
1) Normal temperature 2) New erythema and purulent drainage at the planned insertion site 3) History of a healed paper cut 4) Patient preference for the right side Correct Answer: New erythema and purulent drainage at the planned insertion site Explanation: Active infection at the intended insertion site increases the risk of catheter-related infection. An alternative site or plan should be considered.Page 2
Question 4: A patient develops new lower-extremity weakness after a myelographic lumbar puncture. What is the safest nursing response?
Choices:
1) Discharge the patient if pain is controlled 2) Assume weakness is caused by fasting 3) Encourage unassisted ambulation 4) Treat the neurologic change as urgent and notify the procedural team immediately Correct Answer: Treat the neurologic change as urgent and notify the procedural team immediately Explanation: New neurologic de�cit after a neuraxial procedure is abnormal and may indicate a serious complication. Rapid neurologic assessment and escalation are required.Question 5: A patient receiving moderate sedation for ERCP becomes progressively less responsive. Which nursing assessment is most important immediately?
Choices:
1) Urine speci�c gravity 2) Airway patency and ventilation 3) Peripheral vision 4) Hair color
Correct Answer: Airway patency and ventilation
Explanation: Sedation can progress to deeper levels and cause airway obstruction or respiratory depression. Airway and ventilation are the immediate priorities when responsiveness decreases.Page 3
