C 0.001
D. one-millionth - correct answer C. 0.001
A pair of reciprocal numbers, when
multiplied together, have a value of +
In this case, 1,000 x 0.001 = 1
What is the reciprocal of 5?
multiplied together, have a value of 1
A. one-hundredth
B. 5
,C. 1/5
D. one-millionth - correct answer C. 1/5
In this case, 5 x 1/5 = 1
What is the reciprocal of 1/10?
A. one-hundredth
B. 10
C. 1/10
D. one-millionth - correct answer B. 10
A sack contains 6 pounds of flour. The contents of the bag are increased by a factor of 5. How
much flour is in the bag?
A. 6 pounds
B. 11 pounds
C. 60 pounds
D. 30 pounds - correct answer D. 30 pounds
A bouquet has 30 flowers. The size of the bouquet is decreased by a factor of 3. How many
flowers remain?
A. 27
B. 0
C. 10
D. 15 - correct answer C. 10
The term "decrease by a factor" means to
divide.
= 10.
Which of the following is not a measure of area?
A. square cm
B. meters squared
,C. cubic meters
D. feet x feet - correct answer C. cubic meters
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 - correct answer 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
What are the units associated with the circumference of a circle?
A. mm
B. mm?
C. cm3
D. mA - correct answer A. mm
The circumference of a circle is the length
of the circle's outer boundary and is
measured in units of length.
The volume of a cystic structure is estimated from sonographic data. Which of the following is
an acceptable measurement of this volume?
A. 6
, B. 6 cm
C. 6 cm2
D. 6 cm3 - correct answer D. 6 cm3
The units of volume are length cubed, such
as ft° or cubic centimeters. Volume may
also be expressed as length to the third
power.
A has no units, whereas B and C have
units of length and area.
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 - correct answer 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 relationship between miles and centimeters (relating one unit
of distance to another). When units are changed, the actual amount does not change. For
example, ten dimes provide the same purchasing power as four quarters. The units may be
different, but the "total picture" remains the same.
