The crystals on our transducer in echo is made of ___

Answer explanation

lead zirconate titanate

Adult TTE probes have a frequency range of __

• 2-3 MHz

• 2-3.5 MHz

• 3-4.5 MHz

• 1.5-3 MHz

Neonates are scanned with a __ MHz frequency probe or higher

The optimal 2D echo image is acquired when the probe is ___ to the structure being imaged aka on-axis

• perpendicular

• parallel

• adjacent

Answer explanation

aka 90 degrees

If there is too much LV apex in the parasternal long axis, the transducer is probably positioned too __/_.

• lateral

• inferior

• medial

• superior

Answer explanation

therefore we should move superiorly/medially

The ___ view shows all of the walls in the same plane concurrently, providing a great representation of global function.

• parasternal long

• parasternal short

• 2C

• 3C

The apical views allow us to appreciate __ different walls in their entirety (apex to base). However, the tradeoff is that we can't view all walls concurrently.

• 2

• 3

• 4

Answer explanation

We switch from 4C to 2C to 3C to visualize each wall

The typical M-Mode sweep speed is __ mm/sec

• 50

• 25

• 100

• 125

Answer explanation

time is represented horizontally

With pericardial effusion, ___ is useful for ruling out hemodynamic compromise such as RV diastolic collapse.

• m-mode

• color doppler

• PW doppler

• CW doppler

The ideal Doppler angles for echo specifically are and _ degrees to the blood flow.

• 90

• 0

• 180

• 60
