If the output power setting is at 50% and this indicates 0dB, increasing the power by: Correct Answer: 3dB will increase the power output by a factor of 2 
 
An increase in power of 3dB indicates an increase of 2X the original power. Every 3dB that the power increases will double the power output. 50% x 2 = 100% 
 
The doppler tracing demonstrates electrical noise. How can you reduce or eliminate this artifact? Correct Answer: Increase the wall filter settings 
 
Noise can be reduced by decrea...

1. What action would be most in keeping w the ALARA principle while performing a diagnostic ultrasound exam? CORRECT ANSWERS: Complete the diagnostic scan in a timely fashion at the lowest output power that achieves a quality image 
 
Advocating use of the ALARA principle (as low as reasonably achievable) prudently minimizes the risk of bio effects (even tho epidemiological studies have revealed no known risk associated with the use of diagnostic ultrasound). 
 
2. During performance of an obst...
