What would be the most appropriate nursing response to a woman who says, “My sister had a child with Tay-Sachs disease, and I want to know if I could have a child with this condition”?

The hardest structure of tooth is:

With a 5 MHz transducer the sound wave is traveling through a medium at a speed of 1500 m/s.  The depth is decreased from 8 cm to 4 cm.  What happens to the pulse repetition frequency?

As path length increases the attenuation coefficient in soft tissue increases.

The frequency of a continuous acoustic wave is 5MHz.  The wave is then pulsed with a duty factor of 0.1, the period stays the same.  What is the pulsed frequency?

The concentration of energy in a sound beam is called __________ .

Units of w/cm2  refers to:

Frame rate and the time of each frame are reciprocals.

If you wish to use an array transducer that allows you to control transmit focal depth, what type would you select?
