A sonographer measures the perimeter of an anatomical structure. Which of the following choices is a
reasonable value for boundary of a structure. For example, a the measurement?
A. 6 cm?
B. 5 cc
C. 15 mm
D. 18 dB -✔✔C. 15mm
"Perimeter" means the length of the outer
following choices is a reasonable value for
boundary of a structure. For example, a
the measurement?
square with an edge that is 5 inches long

The speed of red blood cells traveling through a blood vessel is 750 cm/sec. You are asked to measure
this speed in miles per hour. What information would be sufficient for you to complete your task?
A. how many seconds in a minute
and how many blood cells in the vessel
B. the number of miles in a meter
C. how many seconds per hour and the number of miles in a centimeter
D. the direction of red blood cell motion and the Doppler shift frequency -✔✔C. how many seconds per
hour and the number of miles in a centimeter
To convert one unit to another requires a factor that relates the two terms. For example, to change a
measurement of length from feet into inches, we must know how many inches are in a foot. In this case,
we are asked to convert cm per sec into miles per hour. Therefore, we require two pieces of
information: the relationship between seconds and hours (relating one unit of time to another) and the
