,Chapter 1: Before, During, and After the Ultrasound Examination
Multiple-Choice Questions (40 Questions)
1. A patient arrives for an abdominal ultrasound examination. The sonographer should verify the
patient's identity using at least how many identifiers?
A) One identifier
B) Two identifiers
C) Three identifiers
D) Four identifiers
Correct Answer: B
Rationale:
Why B is correct: Standard patient safety protocols require verification using at least two patient
identifiers (e.g., name and date of birth) before beginning any procedure.
Why A is incorrect: One identifier is insufficient and increases the risk of patient misidentification.
Why C is incorrect: While three identifiers may be used, two is the minimum standard.
Why D is incorrect: Four identifiers are not required.
2. During an ultrasound examination, the sonographer notices the patient is anxious and breathing
rapidly. What is the most appropriate initial action?
A) Continue the examination quickly to minimize patient discomfort
B) Stop the examination and call for assistance
C) Explain the procedure and encourage slow, deep breathing
D) Administer a sedative
Correct Answer: C
Rationale:
Why C is correct: The sonographer should provide reassurance and explain the procedure to reduce
anxiety. Encouraging slow, deep breathing can help the patient relax and improve image quality.
Why A is incorrect: Rushing the examination may compromise image quality and patient care.
Why B is incorrect: Calling for assistance is not warranted for mild anxiety.
Why D is incorrect: Sonographers cannot administer sedatives.
3. A patient is scheduled for a pelvic ultrasound with a full bladder technique. What instructions should
the sonographer provide?
A) Empty the bladder completely before the examination
B) Drink 32 ounces of water 1 hour before the examination and hold urine
C) Drink 8 ounces of water immediately before the examination
D) No specific preparation is needed
Correct Answer: B
Rationale:
Why B is correct: For a pelvic ultrasound, the patient should drink 32 ounces of water 1 hour before the
examination and avoid voiding. A full bladder displaces the bowel and provides an acoustic window for
visualizing pelvic structures.
Why A is incorrect: An empty bladder would not provide the needed acoustic window.
,Why C is incorrect: Drinking only 8 ounces immediately before may not adequately fill the bladder.
Why D is incorrect: Specific preparation is required for pelvic ultrasound.
4. The sonographer is preparing for an abdominal ultrasound examination. Which transducer frequency
is most appropriate for an average-sized adult?
A) 2-3 MHz
B) 3.5-5 MHz
C) 7-10 MHz
D) 12-15 MHz
Correct Answer: B
Rationale:
Why B is correct: For abdominal imaging in an average-sized adult, a curvilinear transducer with a
frequency of 3.5-5 MHz provides the best balance of penetration and resolution.
Why A is incorrect: 2-3 MHz provides greater penetration but lower resolution.
Why C is incorrect: 7-10 MHz has limited penetration and is better suited for superficial structures.
Why D is incorrect: 12-15 MHz is used for very superficial structures.
5. During an ultrasound examination, the patient reports pain when the sonographer applies transducer
pressure. What is the most appropriate action?
A) Continue with the same pressure to obtain diagnostic images
B) Reduce transducer pressure and document the patient's pain response
C) Abort the examination immediately
D) Apply more coupling agent and increase pressure
Correct Answer: B
Rationale:
Why B is correct: The sonographer should reduce pressure while obtaining images, document the
patient's pain response, and correlate with findings. Pain with transducer pressure (sonographic Murphy
sign) can be a diagnostic indicator.
Why A is incorrect: Continuing with painful pressure is inappropriate.
Why C is incorrect: Aborting the examination is not warranted unless the patient cannot tolerate it.
Why D is incorrect: Increasing pressure would worsen the patient's pain.
6. Which of the following is the correct sequence for an abdominal ultrasound examination?
A) Survey scan, focused examination, documentation
B) Focused examination, survey scan, documentation
C) Documentation, survey scan, focused examination
D) Survey scan, documentation, focused examination
Correct Answer: A
Rationale:
Why A is correct: The standard sequence is survey scan (overview of anatomy), focused examination
(detailed assessment of specific structures), and then documentation (recording images and
measurements).
Why B is incorrect: The focused examination follows the survey scan.
, Why C is incorrect: Documentation follows the examination.
Why D is incorrect: Documentation follows the focused examination.
7. A patient with a history of abdominal surgery presents for an ultrasound. What technical consideration
is most important?
A) Use a higher frequency transducer
B) Increase the depth setting
C) Be aware of potential adhesions and altered anatomy
D) Apply less coupling agent
Correct Answer: C
Rationale:
Why C is correct: Previous abdominal surgery can result in adhesions and altered anatomy, which may
affect the sonographic appearance and require modified scanning techniques.
Why A is incorrect: Transducer frequency selection depends on patient body habitus, not surgical history.
Why B is incorrect: Depth settings should be adjusted based on the structures being examined.
Why D is incorrect: Adequate coupling agent is always needed.
8. The sonographer is performing a right upper quadrant ultrasound. Which patient position is typically
used to optimize visualization of the gallbladder?
A) Supine only
B) Left lateral decubitus
C) Prone
D) Trendelenburg
Correct Answer: B
Rationale:
Why B is correct: The left lateral decubitus position is used to optimize gallbladder visualization by
allowing stones and sludge to layer dependently and by displacing bowel.
Why A is incorrect: Supine is the starting position, but additional positions improve visualization.
Why C is incorrect: Prone is not typically used for gallbladder imaging.
Why D is incorrect: Trendelenburg is not routinely used for gallbladder imaging.
9. What is the primary purpose of documenting a survey scan in an abdominal ultrasound?
A) To measure specific organ dimensions
B) To provide an overview of anatomy and identify areas requiring focused evaluation
C) To calculate organ volumes
D) To perform Doppler measurements
Correct Answer: B
Rationale:
Why B is correct: The survey scan provides an overview of the abdominal anatomy and helps identify
areas that require focused evaluation.
Why A is incorrect: Measurements are typically obtained during the focused examination.
Why C is incorrect: Volume calculations are not the primary purpose of a survey scan.
Why D is incorrect: Doppler measurements are part of the focused examination.
