Answers | Study Pack | 100% Accurate
• THE BASICS; what is the name of the horizontal axis of a graph? -✓✓x-axis
the horizontal axis of a graph is the x-axis. the x-axis extends side to side.
• THE BASICS; how are scores on the ultrasound board exams related to study
time? -✓✓directly ;
two variables are related when changes in one variable result in changes in the
other. when the changes go in the same direction (both increase or both decrease),
variables are directly related. Since scores increase as study time increases, these
variables are directly related.
• THE BASICS; how are caloric intake and weight related? -✓✓directly ;
these two terms are directly related. as food intake increases, weight increases.
similarly, as food intake decreases, weight decreases.
• THE BASICS; how is weight related to a sonographer's time spent exercising? -
✓✓inversely ;
two variables are related when changes in one variable result in changes in the
other. when the changes follow in the opposite direction (one increases as at the
other decreases), the variables are inversely related.
• THE BASICS; what is the reciprocal of 1,000? -✓✓0.001 ;
a pair of reciprocal numbers, when multiplied together, have a value of 1. in this
case, 1,000 x 0.001 = 1.
• THE BASICS; what is the reciprocal of 5? -✓✓1/5 ;
a pair of reciprocal numbers, when multiplied together, have value of 1. in this
case, 5 x 1/5 = 1
• THE BASICS; what is the reciprocal of 1/10? -✓✓10 ;
a pair of reciprocal numbers, when multiplied together, have value of 1. in this
case, 10 x 1/10 = 1
• THE BASICS; 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? -✓✓30 pounds ;
,the term "increase by a factor" means to multiply. 6 x 5 = 30 pounds.
• THE BASICS; a bouquet has 30 flowers. the size of the bouquet is decreased by a
factor of 3. how many flowers remain? -✓✓10 ;
the term "decrease by a factor" means to divide. 30/3 = 10.
• THE BASICS; which of the following is not a measure of area?
A. square cm
B. meters squared
C. cubic meters
D. feet x feet -✓✓cubic meters ;
Cubic meters are not used to measure
area; they are used to measure volume. An area is measured in units of distance
squared. For example, a rectangle's area is
its length multiplied by its width, and can be reported in square feet, in^2, or
square miles
• THE BASICS; a sonographer measures the perimeter of an anatomical structure.
which of the following choices is a reasonable value for the measurement?
A. 6 cm^2
B. 5 cc
C. 15 mm
D. 18 dB -✓✓15 mm
"perimeter" means the length of the outer boundary of a structure. for example, a
square with an edge that is 5 inches long will have a perimeter measuring 20 inches
(four sides, each with a length of 5 inches).
• THE BASICS; what are the units associated with the circumference of a circle? -
✓✓mm ;
the circumference of a circle is the length of the circle's outer boundary and is
measured in units of length
• THE BASICS; 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 cm^2
D. 6 cm^3 -✓✓6 cm^3
,the units of volume are length cubes, such as ft^3 or cubic centimeters. volume
may also be expressed as length to the third power.
• THE BASICS; the speed of the 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? -✓✓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. now 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.
• THE BASICS; how much bigger is one billion than one thousand? -✓✓1,000,000
times ;
a billion is one million times larger than a thousand. a million is 1,000,000.
• THE METRIC SYSTEM; Select the sequence that appears in increasing order.
A. mega, kilo, hecto, milli, gigi
B. nano, milli, micro, deci, deca, mega
C. centi, deci, deca, hecto
D. milli, hecto, centi, deci, nano, gigi -✓✓centi, deci, deca, hecto;
centi means "one-hundredth", deci means "one tenth", deca means "ten", and hecto
means "hundred". this sequence is increasing, starting from the smallest and ending
with the largest.
• THE METRIC SYSTEM; How many nanoseconds are in 7 seconds? -
✓✓7,000,000,000 ;
nano means billionth. there are one billion billionths in one second. therefore, there
are seven billion billionths in seven seconds.
, • THE METRIC SYSTEM; the letters below represent the abbreviations for the
prefixes of the metric system. select the sequence that appears in decreasing order.
A. m, k, M, g, da
B. a, m, k, d, u
C. g, k, di, m, u, n
D. M, k, da, d, c -✓✓M, k, da, d, c ;
M stands for mega and means "millions." k stands for kilo and means "thousands."
da stands for deca and means "tens." d stands for deci and means "one-tenth." c
stands for centi and means "one-hundredth." Thus, this sequence is of decreasing
numbers.
• THE METRIC SYSTEM; Match the following prefixes with their meanings.
A. mega. 1. hundreds

You should be familiar with the
abbreviations, prefixes, and meanings for
all the terms associated with the metric system.
• THE METRIC SYSTEM; Which term is the reciprocal of mega?
A. nano
B. kilo
C. macro
D. micro -✓✓micro ;
mega means million. the reciprocal of million is millionth. micro means millionth.
