DMS 101 Midterm 1 (Unit Exam 1 & 2) 2026 – Diagnostic Medical Sonography
Fundamentals Study Guide
The ultrasound request form contains the patient's identification number. - correct answer ✔✔
True.
The ultrasound request form should include the patient's identification data, the clinical
symptoms, the type of examination requested, and the reason for the examination.
Sources of infection for HBV and HIV include saliva. - correct answer ✔✔ True
HBV and HIV can be transmitted in body fluids, such as blood, saliva, semen, vaginal secretions,
amniotic fluid, cerebrospinal fluid, synovial fluid, and pericardial fluid.
Sagittal and coronal scanning plane images show only longitudinal sections of structures. -
correct answer ✔✔ False
A structure's appearance in any image, sagittal or otherwise, depends on how it lies (or is
situated or oriented) in the body. For example, a sagittal scanning plane image at the mid
epigastrium shows longitudinal sections of some structures (aorta, superior mesenteric artery,
for example) and axial sections of other structures (pancreas body, splenic vein, for example).
Transverse scanning plane images show only axial or short axis sections of structures. - correct
answer ✔✔ False
Long axis measurements are taken in either the sagittal or coronal scanning plane. - correct
answer ✔✔ False
,The Worklist electronic program allows sonographers to - correct answer ✔✔ query for patient
demographic information from the ultrasound system.
The advantages of the Radiology Information System include appointment scheduling and the
use of work lists. - correct answer ✔✔ True
The Radiology Information System (RIS) can be integrated with other hospital information
systems, allowing patient scheduling, the use of work lists, and digital dictation.
Teleradiology involves radiologic consultations done within the imaging center where an
examination was performed. - correct answer ✔✔ False
PACS is a computer technology system that automatically selects the correct frequency, depth,
and focal zone controls. - correct answer ✔✔ False
Most hospitals and imaging centers currently run filmless by using a computer technology
system called PACS, an acronym for Picture Archiving and Communication System. This
computer technology allows for improved image resolution as images are stored in a digital
format and are software controlled. Ultrasound images are acquired digitally and are viewed
and stored on a computer and/or network server. This system can be dedicated to the
ultrasound department or used on a larger scale throughout the entire radiology division and
hospital. PACS can communicate with outside hospitals and imaging centers located anywhere
in the world that are also equipped with PACS capabilities.
If patients ask about the ultrasound findings, the sonographer should - correct answer ✔✔
explain that they do not make diagnoses but will provide the images to the interpreting.
If a patient is incapacitated and unable to communicate, the sonographer should obtain
permission to perform an invasive procedure from - correct answer ✔✔ a patient
representative.
, If a patient is incapacitated and cannot speak or sign, a patient representative, such as a family
member or the referring physician can grant permission for an invasive procedure to be
performed.
OSHA classifies occupational injuries as repetitive motion injury, repetitive strain injury,
musculoskeletal strain injury. - correct answer ✔✔ True.
According to OSHA, an occupational injury can be classified under the categories of repetitive
motion injury (RMI), repetitive strain injury (RSI), and musculoskeletal strain injury (MSI).
Ninety percent of sonographers suffer from some form of WRMSD and of those, 30% will
experience a career-ending injury. - correct answer ✔✔ False
Valuable information has been obtained from surveys of sonographers and sonologists
regarding the number of occurrences of musculoskeletal symptoms, including pain, with up to
90% of sonographers suffering from some form of WRMSD. Of those, 20% will experience a
career-ending injury.

*Pancreas*
Liver
Spleen
Which structure is intraperitoneal? - correct answer ✔✔ *Gallbladder*
Pancreas
Urinary bladder
Abdominal aorta
Which structure is oriented horizontally in the body? - correct answer ✔✔ Abdominal aorta
