A D-dimer test is performed in a patient in whom a pulmonary embolism is suspected. The value comes back at 379 mg/L. What does this suggest?
 
  a. Almost completely establishes the pres-ence of pulmonary embolism.
  b. Almost completely rules out pulmonary embolism.
  c. Establishes roughly a 50/50 chance of pulmonary embolism.
  d. Is indeterminate but highly suggestive of pulmonary embolism.

Question 2

How does impedance plethysmography determine the presence or absence of deep vein throm-bosis?
 
  a. Notes resistance to electrical current asso-ciated with blood flow.
  b. Radioactive isotopes target clots and show hot on gamma cameras.

Answer to Question 1

ANS: B
The specificity D-dimer enzyme-linked immunosorbent assay (ELISA) can exclude all but 5 to 10 of patients with acute pulmonary embolism, so this test has been used as an important early assessment. The specificity of the test is only 39, but a value less than 500 mg/L has been shown to rule out venous thromboembolic disease in 98 of patients.

Answer to Question 2

ANS: A
Impedance plethysmography, a noninvasive method, measures electrical impedance to blood flow, which changes with inflation and deflation of a lower-extremity cuff.
