1. A radiographer receives an order for an AP supine abdomen
on a patient who has just returned from surgery with a
nasogastric (NG) tube connected to suction. What is the correct
action regarding the NG tube during the exam?
A) Clamp the tube for the duration of the exam
B) Disconnect the tube from suction for the exam
C) Leave the tube connected to suction
D) Remove the NG tube before the exam
Answer: B
1
,Rationale: The NG tube should be disconnected from suction for
the exam. If suction is left on, air may be continuously removed
from the stomach, altering the normal appearance and
potentially creating artifact that could be mistaken for
pathology. The tube itself should remain in place, but suction is
temporarily paused. The radiographer should never clamp or
remove an NG tube without an order.
2. A patient is transported to the radiology department on a
stretcher with a full liter bag of IV fluids infusing. The IV bag is
hanging approximately 3 feet above the patient's arm. The
radiographer notices that the IV tubing has become kinked.
What is the most appropriate action?
A) Unkink the tubing and continue the exam
B) Call the nurse to have the IV restarted
C) Lower the IV bag to the level of the patient's heart
2
, D) Discontinue the IV immediately
Answer: A
Rationale: The radiographer can safely unkink the IV tubing to
restore flow. The height of the bag (3 feet above) is appropriate
for gravity infusion (36-40 inches is standard). Lowering the bag
would decrease flow rate. There is no indication to discontinue or
restart the IV. This falls within the radiographer's scope of basic
patient care.
3. Which of the following best describes the correct patient
positioning for an upright chest radiograph to demonstrate a
small pleural effusion?
A) AP projection, patient standing with back to the image
receptor
B) PA projection, patient standing, leaning forward slightly
3
, C) Lateral decubitus projection, affected side down
D) Lateral decubitus projection, affected side up
Answer: C
Rationale: A lateral decubitus projection with the affected side
down allows free fluid in the pleural space to layer along the
dependent chest wall. This small amount of fluid will be visible as
a hazy density along the dependent lateral chest wall. A
standard upright PA chest may not demonstrate small effusions
because fluid layers along the posterior costophrenic angle and
may be obscured by the diaphragm.
4. A patient in the radiology department begins to have a tonic-
clonic (grand mal) seizure. What is the radiographer's priority
action?
A) Place a tongue depressor in the patient's mouth
