With the characteristics of digital memories, regarding the highest number stored, if the
decimal is 63, which of the following would be considered correct for the binary? -
ANSWER - Regarding the highest number stored, if the decimal is 63 the binary would
be: 111111.Find this by dividing 63 by 2 and recording the remainder.
63/2 is 31 with a remainder of 1
31/2 is 15 with a remainder of 1
15/2 is 7 with a remainder of 1
7/2 is 3 with a remainder of 1
3/2 is 1 with a remainder of 1
2/1 is 0 with a remainder of 1
Therefore 63 in binary is 111111
Which of the following terms can also be used interchangeably with transverse wave? -
ANSWER - The terms SHEER WAVE and TRANSVERSE wave can be used
interchangeably. If there is a sound wave in which the particle motion is perpendicular to
the direction of wave travel, it would be considered a transverse wave (sheer wave).
Which of the following could be used to help prevent issues when advancing the guide
wireless bidirectionnally steerable catheter into the heart? Chest-x-rays Fluoroscopy
Cardiac catheterization Using a short sheath - ANSWER - Fluoroscopy
When this guide wireless bidirectionally steerable catheter is being inserted into the
heart, a fluoroscopy can be used to help prevent issues. Another practical tip for
preventing issues could be using a long-access sheath to help avoid injuring the pelvic
veins during navigation.
The Windkessel effect would result in which of the following occurring? 1 Continued flow
in the forward direction
2 Intermittent flow in the forward direction
3 No flow in the forward direction
4 A temporary forward flow followed by a backward flow - ANSWER - Continued flow in
the forward direction
The Windkessel effect would result in the continued flow in the forward direction.
The closure of the aortic valve prevents the backward flow of blood into the heart.
Which of the following would be considered a function of the signal processor?
1 Digitization 2 Time gain compensation 3 Amplitude detection
4 Echoes versus pulsation - ANSWER - Amplitude detection
There are 3 functions of the signal processor:

,In order to increase the number of foci, which of the following would the PRF need to
do?
1. Decrease 2. Remain the same 3. Increase 4. Double - ANSWER - Increase
In order to increase the number of foci, the PRF needs to increase. PRF stands for
pulse repetition frequency.

What effect would inspiration have on the mitral valve velocity? - ANSWER - With
inspiration, the mitral valve velocity would increase. Peak mitral inflow velocity can be
used to predict mitral regurgitation severity.
During Inspiration, what increases and decreases - ANSWER - RA pressure drops, so
more venous return. More blood to lungs, causes less to return to LA, so stroke Volume
is lower.
