Answer to Question 1

ANS: C
For the one-third of patients who do not receive a definitive diagnosis on the basis of the results of noninvasive studies, pulmonary angiography is the test of choice.

Answer to Question 2

ANS: A
Inpatients should undergo an imaging study as the initial test for pulmonary emboli because most will already have elevated D-dimer levels due to comorbid conditions.
