ARDMS RVT UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
COMPREHENSIVE STUDY GUIDE
●● Venous stasis
Answer: Slowed blood flow in veins. Caused by immobility, myocardial
infarction, CHF, hypotension, COPD, obesity, pregnancy, previous DVT,
extrinsic compression, SVC syndrome, paraplegia, surgery associated
conditions.
●● 2 types of Trauma/endothelial damage
Answer: Intrinsic and extrinsic
●● Intrinsic trauma is
Answer: 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.
●● Extrinsic trauma is
Answer: Damage caused by an accident, which can occur at any site of
the body.
●● Hypercoagulability is associated with
,Answer: 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
●● Sensitivity, and
How to calculate?
Answer: -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
●● Specificity, and how to calculate?
Answer: -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
●● Positive predictive value, and how to calculate?
Answer: -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
●● Negative predictive value, and how to calculate?
, Answer: - 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
●● Accuracy, and how to calculate?
Answer: - % 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
●● Brachiocephalic/ Innominate vien formed from confluence of?
Answer: Subclavien and Internal jugular vein
●● Vascular disease more common in women?
Answer: Takayasu's arteritis-tennage to young women more common.
FMD- younger women.
Celiac band syndrome- young athletic women.
●● Vascular disease more common in men?
Answer: Obliteritis angitis(bergers disease)- younger <40 men, heavy
smokers.
Popliteal artery entrapment syndrome- young athletic men.
