Hesi Rad V2 Exam Questions & Expertly Verified Answers,
.
A Step-Up Transformer With 300 Turns In The Primary Coil Is Supplied With 220 Volts To This
Primary. How Many Secondary Turns Are Needed To Produce A 66,000 Volt Output?
90,000 Turns
What Is The Result If The Total Lead Content Of A Grid Is Decreased?
Decreased Scatter Absorption.
What Is The Purpose Of Shuttering?
To Black Out Areas Of Light And Make Fine Details More Visible.
In Conventional Tomography, The Radiographer Is Able To Control The Thickness Of The
Tomographic Slice By Altering Which Of The Following?
Exposure Angle.
Which Type Of Exposure Technique Chart Would Allow The Radiographer To Make Small, Fine
Adjustments For Orthopedic Work?
Variable Kilovolts Peak (Kvp).
,An Imaging Department, Having Difficulty Obtaining Acceptable Tangential Patella Images, Has
Opted To Have The Post Processing Mode Set To "Fixed" For All Patella Images. Why Is This A
Good Choice?
Fixed Mode Works Well For Exams Where It Is Difficult To Center The Image On The Image
Receptor (Ir).
Pelvis Routine Calls For An Anteroposterior (AP) With A Perpendicular Central Ray (CR), And An
Axial Ap With A 40 Degree Cephalic Angle. Using A Caliper Measurement, The Technique Chart
Yields A Perfect Set Of Exposure Factors For The Perpendicular AP. How Will The Necessary
Exposure Factors For The Axial Differ From The Perpendicular AP?
Greater Measurement, Higher Kilovolts Peak (Kvp) And Milliampere-Seconds (mAS).
Which Advantage Does A 500 Milliampere (mA) Station Have Over A 200 mA Station?
Increased Photon Flux To The Image Receptor (Ir)
A Radiographer Is Performing A Portable Abdomen Is Using An Image Receptor With An 8:1
Grid. The Radiographer Knows A Technique For The Abdomen Using A 12:1 Grid Is 80 Kilovolts
Peak (Kvp) Using 50 Milliampere-Seconds (Mas). Which Would The New Technique Be In Order
To Maintain Image Quality?
80 Kvp @ 40 Mas.
If 7 Milliampere-Seconds (Mas) Provides Optimal Density Without A Grid, Which Mas Should Be
Used With A 12:1 Grid?
,35
How Does A Radiographer Maximize Signal To Digital Image Receptors? (Select The Three That
Apply.)
Compression Of The Body Part.
Shorter Source To Image Receptor Distance (Sid).
Longer Exposure Time.
What Results From Utilizing A Lower Ratio Grid?
Lower Contrast, But Greater Error Margin In Central Ray (Cr) Placement.
Why Is It Important For The Radiographer To Observe The Milliampere Seconds (Mas) Readout
At The End Of Each Exposure When Using Automatic Exposure Control (Aec)?
This Value May Be Used As A Basis For Calculating Manual Techniques.
How Does Emphysema Impact Radiographic Imaging Of The Chest?
Emphysema Is A Destructive Disease, Meaning The Chest Tissue Is More Radiolucent.
If Computed Radiography (Cr) Imaging Plates (Ip) Haven't Been Used, How Often Should They Be
Erased?
48 Hours.
, In Which Way Can The Radiographer Minimize Motion Due To Peristalsis?
Decrease Exposure Time.
Which Best Describes Anode Heel Effect?
A Phenomenon Where X-Ray Intensity Is Greater Under The Cathode.
Which Will Increase The Appearance Of Noise In A Digital Image, Assuming Only The Named
Factor In Each Response Is Changed?
Large Matrix.
Which Is The Preferred Method For Indicating The Correct Anatomic Side On A Radiographic
Image?
Place A Side Marker Directly On The Image Receptor (Ir) Prior To Exposure.
If A Radiographer Wanted To Double Image Density Without Doubling The Patient's Dose,
Which Action Should Be Taken?
Increase Kilovolts Peak (Kvp) By 15%
Which Statement Is Correct Regarding The Relationship Of Patient Dose To Exposure Index (Ei)?
Ei Gives An Approximation Of The Patient's Dose.
