CCI REGISTERED CARDIAC SONOGRAPHER
(RCS) 2026 EXAM COMPLETE (384) CURRENT
TESTING QUESTIONS AND DETAILED
CORRECT ANSWERS|GUARANTEED PASS.
CCI RCS
Ace your preparation with this CCI Registered Cardiac
Sonographer (RCS) Exam, designed to assess comprehensive
knowledge and clinical competency in cardiac sonography. It
focuses on echocardiographic imaging, cardiac anatomy and
physiology, hemodynamics, pathology recognition, and patient
care. The exam strengthens diagnostic reasoning and technical
skills in cardiovascular ultrasound practice. Suitable for cardiac
sonographers and certification candidates.

What kind of wave is a sound wave ✓ ✓ ...... ANSWER .......
sound waves carry energy from one place to another, they
are mechanical and longitudinal waves
What are acoustic variables ✓ ✓ ...... ANSWER .......
pressure, density, distance
Equation for pressure ✓ ✓ ...... ANSWER ....... force/area
What are the 7 acoustic parameters ✓ ✓ ...... ANSWER
....... period, frequency, amplitude, power, intensity,
wavelength, propagation speed
Period ✓ ✓ ...... ANSWER ....... length of time it takes for
a wave to vibrate one cycle, reported in units of time,
, Page 3 of 67
determined by the sound source and cannot be changed by
the sonographer
Frequency ✓ ✓ ...... ANSWER ....... number of
wavelengths that occur in a specific time, reported in units
per second or Hz, determined by the sound source, cannot
be changed by the sonographer
How are frequency and period related ✓ ✓ ...... ANSWER
....... reciprocals and they are reported in complementary
units
Infrasound ✓ ✓ ...... ANSWER ....... too low to hear,
frequency less than 20Hz
Audible sound ✓ ✓ ...... ANSWER ....... between 20 Hz
and 20 kHz
Ultrasound ✓ ✓ ...... ANSWER ....... too high to hear,
frequency greater than 20kHz
, Page 4 of 67
Amplitude ✓ ✓ ...... ANSWER ....... difference of the max
and min values from the average, reported in any of the units
of the acoustic variables, detemined by sound source
initially but decreases as sound travels through the body,
can be changed by the sonographer
Power ✓ ✓ ...... ANSWER ....... rate of energy transfer,
can be reported in units of watts, determined by the sound
source, can be changed by the sonographer
How are amplitude and power related ✓ ✓ ...... ANSWER
....... power is proportional to amplitude squared
Intensity ✓ ✓ ...... ANSWER ....... concentration of energy
in a sound beam, reported in units of watts/cm2, determined
by sound source only, can be changed by the sonographer
How are power and intensity related ✓ ✓ ...... ANSWER
....... proportional
How are intensity and amplitude related ✓ ✓ ...... ANSWER
....... power is proportional to amplitude squared
