Answer to Question 1

B
Ventricular dysrhythmias result from an ectopic focus in any portion of the ventricular myocardium. The usual conduction pathway through the ventricles is not used, and the wave of depolarization must spread from cell to cell. As a result, the QRS complex is prolonged and is always greater than 0.12 second. It is the width of the QRS, not the height, that is important in the diagnosis of ventricular ectopy.

Answer to Question 2

A, B, D
No absolute contraindications to thoracentesis exist, although some risks may contraindicate the procedure in all but emergency situations. These risk factors include unstable hemodynamics, coagulation defects, mechanical ventilation, the presence of an intra-aortic balloon pump, and patients who are uncooperative. It is used most often as a diagnostic measure; it may also be performed therapeutically for the drainage of a pleural effusion or empyema.
