3. Equipment Operation, Quality Control, and Imaging Informatics
4. Image Acquisition, Processing, and Quality Evaluation
5. Radiographic Procedures and Anatomical Positioning
1. A limited scope operator prepares to perform a portable chest radiography exam on a patient in
the intensive care unit who is unresponsive. What is the primary ethical and legal standard
regarding patient consent in this emergency scenario?
A. Written informed consent must be signed by a legal proxy before any imaging procedure can
proceed.
B. Implied consent applies because emergency situations where a patient cannot consent
assume they would want life-saving care.
C. The technologist can waive all identity verification steps if the patient is unconscious and
unaccompanied.
D. Verbal consent must be obtained from the nursing staff acting as temporary legal guardians.
CORRECT ANSWER : B
Rationale: Implied consent is legally recognized in emergency situations where a patient is
incapacitated, unconscious, or unable to communicate, under the legal fiction that a reasonable
person would consent to necessary diagnostic and life-saving procedures. Option A is incorrect
because written informed consent is typically required for invasive procedures rather than
routine diagnostic imaging. Options C and D are incorrect because patient identification
protocols must still be strictly followed regardless of consciousness status.
,2. During a routine extremity procedure, a patient begins to exhibit signs of an acute anxiety attack,
hyperventilating and complaining of dizziness and tingling in the fingers. Which of the following
is the most appropriate initial management step for the limited operator?
A. Administer oxygen via nasal cannula at 15 liters per minute immediately without a physician
order.
B. Instruct the patient to calm down and breathe slowly, potentially using a paper bag to
help restore carbon dioxide balance if advised.
C. Immediately leave the room to locate the attending radiologist while locking the door behind
you.
D. Place the patient in the Trendelenburg position to increase cerebral blood flow and minimize
fainting.
CORRECT ANSWER : B
Rationale: Acute anxiety and hyperventilation cause a drop in carbon dioxide levels (respiratory
alkalosis), which leads to symptoms like dizziness and paresthesia; coaching the patient to slow
their breathing helps restore normal blood gas balance. Option A is incorrect because
administering prescription drugs or high-flow oxygen without an order or established protocol
exceeds the scope of practice. Option C is unsafe as an unresponsive or unstable patient should
never be left alone. Option D is incorrect because the Trendelenburg position is used for shock,
not acute hyperventilation.
3. Which of the following specific methods represents the most effective means of breaking the
chain of infection for a pathogen transmitted via droplet nuclei in a healthcare setting?
A. Utilizing standard hand sanitizer containing at least 60% alcohol before touching the patient.
B. Wearing a properly fitted N95 or higher-level particulate respirator mask when entering
the patient care area.
C. Disinfecting the tabletop with a low-level quaternary ammonium compound disinfectant wipe.
D. Requiring the patient to wear clean latex examination gloves during the entire imaging
sequence.
CORRECT ANSWER : B
Rationale: Pathogens transmitted via droplet nuclei (such as Mycobacterium tuberculosis)
remain suspended in the air for long periods and require airborne precautions, including an N95
respirator mask. Option A addresses contact transmission via hands but does not block
inhalation of fine airborne nuclei. Option C is insufficient because low-level disinfectants do not
, kill resilient spores or specific airborne pathogens. Option D is irrelevant to respiratory
transmission.
4. A limited operator accidentally sustains a needlestick injury with a contaminated needle used to
access an IV line. What is the immediate priority action the operator must take according to
standard institutional exposure control policies?
A. Apply a tightly wrapped tourniquet proximal to the puncture site to trap the infectious agent
locally.
B. Wash the exposed puncture site immediately with soap and water, then report the
incident to the supervisor.
C. Squeeze the wound forcefully to express as much contaminated blood and fluid out of the
capillary bed as possible.
D. Soak the affected hand in a concentrated bleach and water solution for ten minutes to
neutralize bloodborne pathogens.
CORRECT ANSWER : B
Rationale: Standard post-exposure protocol mandates immediate flushing/washing of the site
with soap and water followed by prompt reporting to initiate occupational health evaluations
and potential prophylaxis. Option A is incorrect because a tourniquet restricts circulation and
does not prevent systemic viral transmission. Option C is contraindicated because squeezing or
massaging tissues increases local micro-trauma and enhances viral entry. Option D is
dangerous as caustic chemicals like bleach cause tissue damage and chemical burns.
5. When assessing a patient's medical record for a contrast-enhanced radiographic examination, the
limited operator notes a history of severe anaphylactic reactions to shellfish and iodine. What is
the most critical immediate action?
A. Proceed with the exam as shellfish allergies are completely unrelated to intravascular
iodinated contrast media.
B. Notify the radiologist or attending physician immediately prior to contrast
administration to evaluate alternative modalities or premedication.
C. Double the dosage of the oral antihistamine the patient took at home to completely block all
potential immune responses.
D. Utilize ionic high-osmolar contrast media instead of non-ionic low-osmolar media to
minimize systemic shock.
CORRECT ANSWER : B
, Rationale: A history of severe anaphylaxis requires physician notification so that pre-medication
regimens (steroids and antihistamines) or alternative non-contrast imaging can be planned.
Option A is incorrect because although shellfish allergy does not directly cause contrast allergy,
patients with severe multi-allergy profiles carry higher risk. Option C is incorrect because
technologists cannot alter or prescribe medication dosages. Option D is incorrect because non-
ionic low-osmolar media have lower adverse reaction rates than ionic agents.
6. Which of the following patient transfer techniques minimizes the risk of orthostatic hypotension
and potential falls when moving a patient from a supine to an upright position?
A. Rapidly lifting the patient into a standing position without pausing to save time during a
heavy imaging schedule.
B. Allowing the patient to sit on the edge of the examination table for a brief period before
standing or transferring.
C. Asking the patient to close their eyes tightly and lean forward aggressively against the chest
board.
D. Utilizing a rigid wooden backboard as a sliding bridge across all wheelchair transfers.
CORRECT ANSWER : B
Rationale: Sitting on the edge of the table (dangling) allows compensatory vascular reflexes to
adjust blood pressure, preventing the sudden cerebral hypoperfusion known as orthostatic
hypotension. Option A causes rapid blood pooling in the lower extremities, triggering dizziness
or syncope. Option C impairs balance and spatial orientation. Option D is unnecessary and
unsafe for ambulatory or semi-ambulatory transfers.
7. Under the legal doctrine of res ipsa loquitur, which translates to "the thing speaks for itself,"
how is negligence established in a medical malpractice lawsuit involving a radiographic error?
A. The plaintiff must present expert witness testimony from three independent radiologists to
prove substandard care.
B. The injury or error is of a nature that ordinarily does not occur in the absence of
someone's explicit negligence, shifting the burden of proof.
C. The healthcare institution assumes absolute strict liability without requiring proof of causation
or duty.
D. The plaintiff must produce a signed written confession from the specific technologist who
performed the scan.
CORRECT ANSWER : B
