QUESTION: 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.

QUESTION: Thermally induced biological effects should be preventable by avoiding a local
tissue temperature increase exceeding:
A: 1 degree C
B: 4 degrees C
C: 10 degrees C

E: None; thermal effects have no threshold. - ANSWER-A: 1 degree C
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.
