Answer to Question 1

1, 3, 4, 5, 6
The purpose of the ventilation-perfusion scan is to diagnose and locate pulmonary emboli. It is also helpful in diagnosing bronchitis, asthma, pneumonia, COPD, and cancer. This scan is not used to diagnose congestive heart failure.

Answer to Question 2

2
High levels of positive end expiratory pressure can cause pneumothorax or decreased venous return. Positive end expiratory pressure does not cause a hemothorax or hypertension.
