3 causes of venous thrombosis also called, Virchow's Triad -CORRECT ANSWER
Venous stasis, trauma/endothelial damage, hypercoagulability
Venous stasis -CORRECT 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 -CORRECT ANSWER Intrinsic and extrinsic
Intrinsic trauma is -CORRECT 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 -CORRECT ANSWER Damage caused by an accident, which can
occur at any site of the body.
, Hypercoagulability is associated with -CORRECT 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? -CORRECT 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? -CORRECT 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? -CORRECT 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? -CORRECT 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
