Which of the following is NOT compliant with HIPAA?
A. Cropping all patient identifiers from images used for teaching purposes
B. Refraining from disclosing patient health information without proper authorization
C. Reviewing your neighbor's medical studies on your hospital PACS system so you
can give her your opinion of her condition
D. Covering your daily requisition list so that the names are not visible to patients and
visitors
E. All of these actions are compliant with HIPAA - Correct Answer-C. Reviewing your
neighbor's medical studies on your hospital's PACS system so you can give her your
opinion of her condition
<The Health Insurance Portability and Accountability Act (HIPAA) includes rules to
protect the privacy of the individual's health information. Answer choice C would of
course violate HIPAA law>
To practice the ALARA principle, which of the following techniques should you employ?
A. Always use the least amount of receiver gain that allows adequate tissue
visualization
B. Adjust the controls so that the MI and TI readouts exceed 1
C. Use the lowest transmit power that allows adequate tissue visualization
D. Use the highest frame averaging (persistence) setting
E. Maximize exposure time - Correct Answer-C. Use the lowest transmit power that
allows adequate tissue visualization
<Use a high gain and low transmit power>
Which of the following occurs when you use the maximum system gain?
A. Increased tissue heating
B. Increased risk of cavitation
C. Fluid Particle streaming
D. Increased sound absorption
E. None of the above - Correct Answer-E. None of the above
When scanning with pulsed-wave Doppler, you would affect the acoustic exposure by
changing which of the following?
A. Doppler gain
, B. High pass filter
C. Pulse repetition frequency
D. Baseline position
E. Doppler angle - Correct Answer-C. Pulse repetition frequency
<The PRF is the number of pulses per second transmitted by the transducer, which
varies with the velocity setting on the spectral display. Increasing PRF has the potential
to increase the acoustic exposure>
Which of the follow would most likely have the highest SPTA value?
A. CW Doppler
B. B-mode real-time scanners
C. Static B-mode scanners
D. PW Doppler
E. Fetal monitor Doppler - Correct Answer-D. PW Doppler
You are performing a sonographic examination and notice that the thermal index (TI) is
greater than 1. Any increase in temperature would be greatest in
A. Liver
B. Lung
C. Kidney
D. Bone
E. Bladder - Correct Answer-B. Bone
During performance of an obstetric ultrasound exam, you adjust the system parameters
to improve the image. Which of the following parameters would increase acoustic
exposure?
A. Increase receiver gain
B. Increase TGC
C. Increase frequency
D. Increase transmit power
E. Increase frame averaging (persistence) - Correct Answer-D. Increase transmit power
<The transmit power is the only control listed that will affect the exposure of the patient
to acoustic power. Gain, TGC, and frame averaging (persistence) do not affect sound
transmission and therefore do not affect exposure. Increasing frequency will not
increase exposure>
What should you do to avoid nosocomial and cross-infection with sonographic probes?
A. Probe cleaning should always precede high-level disinfection
B. Covering a probe with a condom is a sufficient barrier to infection for intracavitary
probes
