RVT ARDMS Exam Review – Expected Questions and
Verified Answers Updated 2026/2027
1. 3 causes of venous thrombosis also called, Virchow's Triad: Venous stasis, trauma/en-
dothelial damage, hypercoagulability
2. Venous stasis: Slowed blood flow in veins. Caused by immobility, myocardial infarction, CHF, hypotension, COPD,
obesity, pregnancy, previous DVT, extrinsic compression, SVC syndrome, paraplegia, surgery associated condi- tions.
3. 2 types of Trauma/endothelial damage: Intrinsic and extrinsic
4. Intrinsic trauma is: Damage to the vessel wall from intravenous drugs or a catheter. Increased use of PICC line
results in higher incidence of upper extremity thrombus, usually developing at most proximal portion of PICC line.
5. Extrinsic trauma is: Damage caused by an accident, which can occur at any site of the body.
6. Hypercoagulability is associated with: Pregnancy, cancer, oral contraceptives and/or hormone
replacement therapy, inherited states,e.g., factor V Leiden or protein C, protein S, or Antithrombin III deficiency
7. Sensitivity, and
How to calculate?: -Ability of a test to detect disease, how many tests are correctly called positive.
- # of true positives divided by # of all positive tests by gold standard, or TP/TP+FN
8. Specificity, and how to calculate?: -Ability of a test to identify normality, or how many results were
correctly called negative.
- # of true negative divided by # of all negative tests by gold standard, or TN/TN+FP
9. Positive predictive value, and how to calculate?: -percentage of test results that accurately predict
abnormality, or what % correctly predicted disease.
- # of true positive test divided by # of all positive tests, or TP/TP+FP
10. Negative predictive value, and how to calculate?: - percentage of test results that accurately predict
normality, or what % correctly predicted absence of disease.
- # of true negatives divided by # of all negative tests, or TN/TN+FN
11. Accuracy, and how to calculate?: - % of correct tests, or how well does the test both detect and rule out
disease.
- total # of correct tests divided by total # of all tests, or TP+TN/TP+FP+FN+TN
12. Brachiocephalic/ Innominate vien formed from confluence of?: Subclavien and
Internal jugular vein

, 13. Vascular disease more common in women?: Taḳayasu's arteritis-tennage to young women more
common.
FMD- younger women.
Celiac band syndrome- young athletic women.
