Exam A Medical Imaging Ultrasound
ACTUAL EXAM 2026/2027 | SIEMENS
Level 1 Ultrasound | Verified Q&A | Pass
Guaranteed - A+ Graded
SECTION 1: SAFETY & BASIC OPERATION (20 Questions)
Q1: A Level 1 operator is preparing to perform an abdominal ultrasound on a patient with a known latex
allergy. The transducer cover in the supply room is labeled "natural rubber latex." What is the correct
action?
A. Proceed with the latex cover; the allergy is mild and unlikely to cause reaction during a short exam
B. Use the latex cover but apply a double layer of gel to create a barrier
C. Select a non-latex transducer cover alternative and document the allergy precautions [CORRECT]
D. Ask the patient to sign a waiver acknowledging the risk
Correct Answer: C
Rationale: Siemens infection control protocols mandate latex-free alternatives for allergic patients to
prevent anaphylaxis, and all precautions must be documented in the patient record.
Q2: During startup of a Siemens Acuson Sequoia ultrasound system, the operator notices the thermal
printer emitting a burning odor. What is the immediate correct action?
A. Continue the exam; the odor is normal for warming thermal elements
B. Power off the system at the main breaker and evacuate the room
C. Power off the printer module using the rear panel switch and notify biomedical engineering
[CORRECT]
D. Spray a fire extinguisher into the printer compartment
Correct Answer: C
,Rationale: Isolating the specific faulty component prevents fire risk while preserving system functionality
for pending exams, per Siemens equipment isolation protocols.
Q3: A pregnant patient at 8 weeks gestation expresses concern about ultrasound safety. The Level 1
operator should explain that:
A. Ultrasound uses ionizing radiation similar to X-ray but at lower doses
B. The ALARA principle ensures mechanical and thermal indices are kept as low as reasonably achievable
[CORRECT]
C. No safety limits exist for first-trimester obstetric ultrasound
D. The exam should be postponed until the second trimester for safety
Correct Answer: B
Rationale: ALARA (As Low As Reasonably Achievable) is the foundational safety principle for diagnostic
ultrasound, requiring operators to minimize exposure time and output power while maintaining
diagnostic quality.
Q4: Which of the following is a required step in the Siemens ultrasound system daily quality assurance
check?
A. Calibrating the Doppler angle correction to 90 degrees
B. Verifying the date and time accuracy on the system clock
C. Checking the transducer housing for cracks, fluid leaks, or cable damage [CORRECT]
D. Replacing all gel packets regardless of expiration date
Correct Answer: C
Rationale: Transducer integrity checks prevent patient electrical shock and ensure image quality;
cracked housings can allow coolant fluid leakage or electrical exposure.
Q5: An operator is setting up for an echocardiogram using a Siemens Acuson SC2000. The patient has an
implanted pacemaker. What safety consideration applies?
A. Ultrasound is contraindicated in all patients with pacemakers
B. The operator should avoid applying transducer pressure directly over the pacemaker generator and
monitor for patient discomfort [CORRECT]
C. The ultrasound system must be grounded to a separate isolation transformer
D. The patient must remove the pacemaker before the exam
,Correct Answer: B
Rationale: While diagnostic ultrasound does not interfere with pacemaker function, direct mechanical
pressure over the generator can cause patient pain or device displacement.
Q6: When cleaning a Siemens ultrasound transducer between patients, which action is correct?
A. Submerge the transducer in enzymatic cleaning solution up to the cable connector
B. Wipe the transducer head and housing with approved disinfectant wipes, avoiding the connector and
strain relief [CORRECT]
C. Spray disinfectant directly onto the transducer face and allow air-drying
D. Autoclave the transducer at 121°C for 15 minutes
Correct Answer: B
Rationale: Fluid ingress at the connector or strain relief damages internal wiring and voids warranty;
approved wipes prevent cross-contamination while preserving transducer integrity.
Q7: A Level 1 operator notices the Mechanical Index (MI) display reading 1.8 during an obstetric exam.
The correct action is:
A. Continue the exam; MI values up to 2.0 are safe for all trimesters
B. Reduce the output power or adjust imaging parameters to lower the MI below 1.0 [CORRECT]
C. Increase the depth to automatically reduce the MI
D. Switch to color Doppler mode, which does not display MI
Correct Answer: B
Rationale: FDA guidelines recommend keeping MI below 1.0 for fetal imaging to minimize potential
cavitation bioeffects; operators must actively control output power.
Q8: During a contrast-enhanced ultrasound (CEUS) exam using sulfur hexafluoride microspheres, the
patient develops urticaria and mild dyspnea. What is the first priority?
A. Continue the exam to complete the vascular phase imaging
B. Administer the ordered contrast dose and observe for 30 minutes
C. Stop contrast administration, activate emergency response, and prepare for anaphylaxis management
[CORRECT]
D. Switch to non-contrast imaging and document the reaction after the exam
, Correct Answer: C
Rationale: Contrast microsphere reactions, though rare, can progress to anaphylaxis; immediate
cessation and emergency preparedness align with Siemens contrast safety protocols.
Q9: The electrical safety check for a Siemens ultrasound system includes verifying:
A. That the power cord is plugged into a battery backup unit exclusively
B. Ground pin integrity on the hospital-grade plug and absence of frayed cables [CORRECT]
C. That the system operates on 220V regardless of local supply voltage
D. Continuity between the patient and the transducer housing
Correct Answer: B
Rationale: Ground integrity prevents electrical shock hazard; frayed cables expose conductors and
violate IEC 60601-1 medical electrical safety standards.
Q10: When positioning a patient for a right upper quadrant ultrasound, which safety consideration is
most important?
A. Elevating the head of the bed to 90 degrees to prevent aspiration
B. Ensuring the patient can maintain the position without respiratory compromise and providing support
pillows [CORRECT]
C. Applying firm pressure to the costal margin regardless of patient feedback
D. Positioning the patient prone to improve acoustic window
Correct Answer: B
Rationale: Patient positioning must balance acoustic access with comfort and respiratory function;
unsupported positions cause muscle strain and shallow breathing, degrading image quality.
Q11: A transducer is dropped on the floor during transport. The Level 1 operator should:
A. Visually inspect for damage and continue using if no cracks are visible
B. Perform the electrical leakage test and structural integrity check, then tag for biomedical inspection if
any abnormality is found [CORRECT]
C. Return it to service immediately; transducers are impact-resistant
D. Dispose of the transducer in biohazard waste regardless of appearance
Correct Answer: B
