Edelman's SPI exam questions UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
THE BASICS; what is the vertical axis of a graph called? y-axis ;
A. z-axis the vertical axis of a graph is called the y-axis and extends up and down
B. x-axis
C. y-axis
D. time-axis
THE BASICS; what is the name of the horizontal axis of a x-axis
graph? 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 directly ;
exams related to study time? 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 inversely ;
time spent exercising? 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 30 pounds ;
contents of the bag are increased by a factor of 5. how the term "increase by a factor" means to multiply. 6 x 5 = 30 pounds.
much flour is in the bag?
THE BASICS; a bouquet has 30 flowers. the size of the 10 ;
bouquet is decreased by a factor of 3. how many flowers the term "decrease by a factor" means to divide. 30/3 = 10.
remain?
THE BASICS; which of the following is not a measure of cubic meters ;
area? Cubic meters are not used to measure
A. square cm area; they are used to measure volume. An area is measured in units of distance
B. meters squared squared. For example, a rectangle's area is
C. cubic meters its length multiplied by its width, and can be reported in square feet, in^2, or
D. feet x feet square miles
THE BASICS; a sonographer measures the perimeter of 15 mm
an anatomical structure. which of the following choices is "perimeter" means the length of the outer boundary of a structure. for example, a
a reasonable value for the measurement? square with an edge that is 5 inches long will have a perimeter measuring 20
A. 6 cm^2 inches (four sides, each with a length of 5 inches).
B. 5 cc
C. 15 mm
D. 18 dB
THE BASICS; what are the units associated with the mm ;
circumference of a circle? 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 6 cm^3
from sonographic data. which of the following is an the units of volume are length cubes, such as ft^3 or cubic centimeters. volume
acceptable measurement of this volume? may also be expressed as length to the third power.
A. 6
B. 6 cm
C. 6 cm^2
D. 6 cm^3
