Final answer:
A bounding, aneurysmal pulse would have a high amplitude and would be represented by the number 4 on the scale.
Step-by-step explanation:
The amplitude of a pulse is a measurement of how far the medium is displaced momentarily from a position of rest. In this case, the scale of amplitude is from 0-4. A bounding, aneurysmal pulse would have a high amplitude and would be represented by the number 4 on the scale. A higher amplitude indicates a stronger and more forceful pulse. In contrast, a lower amplitude, such as 0 or 1, would represent a weaker pulse.
