What is the vertical axis of a graph called? - Answer: y-axis; it extends up and down
What is the name of the horizontal axis of a graph? - Answer: x-axis; extends side to side
How are scores on the ultrasound board exams related to study time? - Answer: directly related;
since scores increase as study time increases, these variables are directly related
How are caloric intake and weight related? - Answer: directly related; as food intake increases,
weight increases
How is weight related to a sonographer's time spent exercising? - Answer: inversely related; 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 the other decreases), the variables
are inversely related
What is the reciprocal of 1,000? - Answer: 0.001; a pair of numbers when multiplied together
have the value of 1. In this case, 1,000 x 0.001 = 1
,What is the reciprocal of 5? - Answer: 1/5; a pair of numbers when multiplied together have the
value of 1. In this case, 5 x 1/5 = 1
What is the reciprocal of 1/10? - Answer: 10; a pair of numbers when multiplied together have
the value of 1. In this case, 10 x 1/10 = 1
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? - Answer: 30 pounds; the term "increase by factor" means to multiply.
6 x 5 = 30 pounds
A bouquet has 30 flowers. The size of the bouquet is decreased by a factor of 3. How many
flowers remain? - Answer: 10; The term "decrease by a factor" means to divide.
30/3 = 10 flowers
Which of the following is not a measure of area?
A. square cm
B. meters squared
C. cubic meters
D. feet x feet - Answer: cubic meters; cubic meters are not used to measure area, they are used
to measure volume.
A sonographer measures the perimeter of an anatomical structure. Which of the following
choices is a reasonable value for the measurement?
A. 6 cm2
B. 5 cc
C. 15 mm
,D. 18 dB - Answer: 6.2 cm2; perimeter means the length of the outer boundary of a structure.
Units of measurement in A, B, and D are not applicable to length.T
What are the units associated with the circumference of a circle?
A. mm
B. mm2
C. mm3
D. m4 - Answer: mm; circumference is the length of the outer boundary and is measured in
units of length.
B and C are units of area and volume. D has units of length to the fourth power, which has no
meaning in geometry.
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 - Answer: 6 cm3; the units of volume are length cubed such as ft3 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 - Answer: C. how many
seconds per hour and the number of miles in a centimeter
How much bigger is one billion that one thousand? - Answer: 1,000,000 times
one billion / one thousand = 1,000,000
Select the sequence that appears in increasing order.
A. mega, kilo, hecto, milli, giga
B. nano, milli, micro, deci, deca, mega
C. centi, deci, deca, hecto
D. milli, hecto, centi, deci, nano, giga - Answer: C, centi-hecto.
Centi = one hundredth
Deci = one tenth
Deca = 10
Hecto = 100
How many nanoseconds are in 7 seconds? - Answer: 7,000,000,000; nano means billionth.
There are one billion billionths in one second. Therefore, there are seven billion billionths in
seven seconds
