What action below would be most in keeping with the
ALARA principle while performing a diagnostic ultrasound
examination?
A: Allow multiple students to scan an obstetrical patient
because the fetus is in a good position for imaging.
B: Prolong the sonogram to make videos of the fetus for
each family member.
C: Complete the diagnostic scan in a timely fashion at the
lowest output power that achieves a quality image.
D: Maximize the acoustic output to brighten the overall
image.
E: Extend the sonogram beyond the intended scope of the
exam requisition. - Answer-C: Complete the diagnostic
scan in a timely fashion at the lowest output power that
achieves a quality image.
What does the ALARA principle stand for? - Answer-As
Low As Reasonable Achievable

During performance of an obstetrical ultrasound exam you
adjust the system parameters to improve the image.
Which of the following parameters would increase acoustic
exposure?
A: Increase gain
B: Increase TGC
C: Increase frequency
D: Increase transmit power
E: Increase frame averaging - Answer-D: Increase
transmit power
While performing a sonogram to minimize risk to the fetus
which imaging mode trade off would be most applicable?
A: Use M-mode instead of pulsed-wave Doppler to
measure the fetal heart rate.
B: Use color Doppler instead of power Doppler to image
the umbilical cord.
C: Use pulsed-wave Doppler instead of power Doppler to
evaluate the fetal heart.
D: Use harmonics instead of fundamental to image the
fetal spine.

E: All of the above. - Answer-A: Use M-mode instead of
pulsed-wave Doppler to measure the fetal heart rate.
Gain, TGC, and frame averaging do not affect _______
and therefore do not affect _______. - Answer--Sound
transmission
-Exposure
T or F: Increasing frequency does not increase exposure. -
Answer-True
What potential bioeffect occurs through absorption of
sound energy by tissue?
A: Cavitation
B: Heating
C: Attenuation
D: Reflection

When practicing universal precautions you should do all of
the following EXCEPT:
, 4|Page
A: Wear gloves when there is a potential for contact with
patient bodily fluids.
B: Change gloves when moving from one patient to
another.
C: Wash hands immediately after gloves are removed.
D: Wear face masks or eye protection whenever there is a
possibility of blood splashing into your face.
E: Wash gloves between exams for re-use from one
patient to another. - Answer-E: Wash gloves between
exams for RE-use from one patient to another.
A nosocomial infection is defined as one that is:
A: Resistant to antibiotics
B: Restricted to the respiratory system
C: Hospital-acquired
D: Not contagious
E: Requires isolation - Answer-C: Hospital-acquired
Thermally induced biological effects should be preventable
by avoiding a local tissue temperature increase exceeding:
A: 1 degree C
B: 4 degrees C
