Davies SPI EXAM QUESTIONS AND ANSWERS 100% SOLVED (Newest 2025) 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. -
Correct Answers ✅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? - Correct Answers ✅As Low As Reasonable Achievable During performance of an obstetrical ultrasound exam you adjust the system parameters to improve the image.

D: Increase transmit power
E: Increase frame averaging - Correct Answers ✅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. 1 / 4

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. - Correct Answers ✅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 _______. - Correct Answers ✅-Sound transmission -Exposure
