DETAILED ANSWERS (VERIFIED ANSWERS)/GRADE A+ ASSURED.
What action below would be most in keeping with the C: Complete the diagnostic scan in a
timely fashion at the lowest output power ALARA principle while performing a diagnostic
that achieves a quality image.
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.
What does the ALARA principle stand for? As Low As Reasonable Achievable
During performance of an obstetrical ultrasound exam
D: Increase
transmit power you adjust the system parameters to improve
the image.

While performing a sonogram to minimize risk to the A: Use M-mode instead of pulsed-
wave Doppler to measure the fetal heart fetus which imaging mode trade off would be most
rate.
applicable?
A: Use M-mode instead of pulsed-wave
Doppler to measure the fetal heart
rate.

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.
