Answer to Question 1

ANS: D
Myocardial hypertrophy and diastolic dysfunction are the results of these alterations, eventually leading to heart failure, arrhythmias, or sudden cardiac arrest. Myocardial hypertrophy and the consequently reduced heart-wall compliance, as well as reduced heart chamber volumes, are re-sponsible for poor tolerance of IV fluids in these patients.

Answer to Question 2

ANS: B
The presence of bronchial injury should be suspected when, after the placement of a chest tube for pleural drainage, large amounts of air continue to exit the chest tube in a synchronized pattern with positive pressure ventilation.
