Answer to Question 1

ANS: A
The balloon inflates during diastole and deflates during systole to enhance perfusion of the cor-onary arteries and cardiac output. The radiopaque tip should reside just beyond the origin of the left subclavian artery within the proximal descending thoracic aorta. The carina can be used as a landmark with the tip of the IABP approximately 2 cm above the carina.

Answer to Question 2

ANS: B
The most common indications for a chest tube are pneumothorax (air in the pleural space) and empyema (pus in the pleural space), although chest tubes may also be used to drain blood (hemothorax) or fluid (hydrothorax) or to install a sealant (e.g., the antibiotic doxycycline) to achieve closure of the pleural space, thereby preventing recurrent pneumothorax or hydrothorax.
