Answer to Question 1

ANS: A
It is difficult to determine whether a Heimlich valve has an ongoing leak unless it is placed to underwater seal. This procedure can be done in the emergency department by placing the Heim-lich valve into a cup of water or by placing it in-line with a water-seal chamber to see whether an air leak is continuing after lung expansion.

Answer to Question 2

ANS: D
The chest tube is multifunctional to allow measurement of the rate of bleeding, to allow the lung to be pulled to the parietal pleural surface to tamponade bleeding, and to allow maximum venti-lation.
