DMS Exam 3 2026 – Diagnostic Medical Sonography Comprehensive
Study Guide
Claudication - correct answer ✔✔ Calf pain associated with exercise
edema - correct answer ✔✔ Abnormal accumulation of fluid in the interstitial tissues
Amaurosis Fagax - correct answer ✔✔ Monocular or binocular vision loss that may be an
impending sign of stroke
TIA - correct answer ✔✔ A transient episode of neurological dysfunction in result of ischemia
CVA - correct answer ✔✔ A rapid loss of blood supply to the brain which may result in
neurological damage or death
Baker's Cyst - correct answer ✔✔ Popliteal cyst in result of collection of synovial fluid often
associated with joint disorders
Anticoagulant - correct answer ✔✔ Warfarin or heparin
D-Dimer - correct answer ✔✔ Blood test used to diagnose thrombus; could predict the need for
sonographic analysis
Bruit - correct answer ✔✔ Unusual sound of blood flow associated with stenosis
Subclavian Steal - correct answer ✔✔ An occlusion in the subclavian artery prior to the
vertebral origin; reversed flow identified
, Characteristics of ECA - correct answer ✔✔ Smaller diameter, branches, resistive waveform,
more medial
Characteristics of ICA - correct answer ✔✔ Bigger in diameter, does not branch, non resistive
waveform, more lateral
Characteristics of the vertebral artery - correct answer ✔✔ Bone shadow, not big in diameter,
velocity not as high as ICA, does not carry as much volume
CCA splits into what - correct answer ✔✔ ICA and ECA
Calf muscle pump - correct answer ✔✔ the muscles in the calf that upon contraction, propel
venous blood toward the heart
Augmentation - correct answer ✔✔ Less likely to be a clot between the transducer, location,
and where we are squeezing
Inspiration on waveform - correct answer ✔✔ No flow and is zero (Close to baseline)
Spontaneous flow - correct answer ✔✔ Happens on it's own
What does valsalva do - correct answer ✔✔ Assess competency of valves. Take a deep breath in
and bare down
Relaxation on waveform - correct answer ✔✔ Point of flow resuming
Incompetent Valve - correct answer ✔✔ Shows up on other side of baseline, reversed flow
