Correct answer: Ensuring clear imaging and patient comfort

The primary consideration when positioning a patient for an ultrasound exam is to ensure both clear imaging and patient comfort. Proper positioning allows the sonographer to gain optimal acoustic windows to the target anatomy, minimizing artifacts and maximizing diagnostic quality. Simultaneously, ensuring the patient is comfortable helps them remain still throughout the procedure, which is vital for obtaining steady and accurate images, contributing to a successful and efficient scan.

Question 152: In pulsed-wave Doppler, aliasing occurs when the sampled Doppler frequency exceeds:

The pulse repetition period
The Nyquist limit (one-half the PRF) (Correct answer)
The transducer center frequency
The maximum depth setting

Correct answer: The Nyquist limit (one-half the PRF)

Aliasing occurs when the Doppler shift frequency exceeds the Nyquist limit, which is half the pulse repetition frequency (PRF).

Question 153: A patient undergoing ultrasound-guided biopsy suddenly develops a rapid heart rate, pallor, and near-syncope. The sonographer should first:

Administer IV fluids immediately
Continue the procedure with increased monitoring

Vasovagal syncope during procedures is managed by stopping the procedure and lowering the patient's head to improve cerebral perfusion.

Question 154: During follow-up imaging of a patient with a treated renal cell carcinoma, ultrasound shows a new hypoechoic lesion in the contralateral kidney. What is the most appropriate next action?

Report findings immediately to the referring physician (Correct answer)
Reassure the patient as contralateral involvement is rare
Perform color Doppler and recommend MRI correlation
Document findings and schedule routine annual follow-up

Correct answer: Report findings immediately to the referring physician

A new suspicious lesion in a patient with known malignancy must be communicated immediately to the referring physician for urgent clinical decision-making.

Question 155: Which factor determines the penetration depth of ultrasound waves?

The amount of ultrasound gel used
The size of the display screen
The frequency of the probe (Correct answer)
The speed of the machine processor

Correct answer: The frequency of the probe

The penetration depth of ultrasound waves is primarily determined by the frequency of the transducer probe. Lower frequency probes (e.g., 2-5 MHz) penetrate deeper into the body but offer lower resolution, making them suitable for imaging deeper structures like abdominal organs. Conversely, higher frequency probes (e.g., 7-18 MHz) provide excellent resolution for superficial structures but have limited penetration depth, requiring a balance between depth and detail for each exam.

Question 156: Which of the following is an example of a reportable adverse event related to ultrasound contrast agents (UCAs)?

Question 160: Harmonic imaging improves image quality primarily by:

Widening the transducer beam at depth
Amplifying near-field gain
Increasing pulse repetition frequency
Using frequencies generated within tissue rather than emitted frequencies (Correct answer)

Correct answer: Using frequencies generated within tissue rather than emitted frequencies

Tissue harmonic imaging detects the second harmonic frequency generated by nonlinear propagation within tissue, reducing near-field clutter and side-lobe artifacts.

Question 161: Which medication is the first-line treatment for anaphylaxis in a clinical setting?

Diphenhydramine (Benadryl)
Epinephrine (adrenaline) (Correct answer)
Albuterol inhaler
Hydrocortisone

Correct answer: Epinephrine (adrenaline)

Epinephrine is the only first-line treatment for anaphylaxis, acting to reverse bronchospasm, vasodilation, and urticaria rapidly.

Question 162: What is the effect of increasing ultrasound frequency on tissue penetration and resolution?

Decreases penetration and improves resolution (Correct answer)
Increases both penetration and resolution
Increases penetration and worsens resolution
Decreases both penetration and resolution

Correct answer: Decreases penetration and improves resolution

Higher frequency ultrasound is attenuated more rapidly (less penetration) but produces shorter wavelengths that improve spatial resolution.

Question 163: When using probe covers for endocavitary ultrasound, what should the sonographer do if the cover tears during the procedure?

Continue the exam and note the torn cover in the report
Complete the exam, then perform high-level disinfection on the probe (Correct answer)
Stop immediately, replace the cover, then resume
Report the incident to infection control but continue

Correct answer: Complete the exam, then perform high-level disinfection on the probe

If a probe cover tears during an endocavitary exam, the exam should be completed if clinically necessary and then the probe must undergo high-level disinfection before its next use.

Question 164: The prefix 'hepato-' refers to which organ?
