Final answer:
Dr. Jones will perform a pericardiocentesis, which is a surgical puncture to remove fluid from the pericardial space to treat the hemopericardium that Mr. Lopez suffers from after the car accident.
Step-by-step explanation:
Dr. Jones will perform a pericardiocentesis to correct the hemopericardium. Hemopericardium is a condition where blood accumulates in the pericardial sac, the protective covering of the heart, and it can lead to cardiac tamponade, a severe compression of the heart that impedes its ability to function. A pericardiocentesis involves a surgical puncture to remove fluid from the pericardial space, thereby relieving pressure on the heart and improving the patient's condition. The connection between this procedure and cardiopulmonary resuscitation (CPR) is that both are emergency interventions used to address critical cardiac conditions: CPR for cardiac arrest and pericardiocentesis for complications such as cardiac tamponade due to a buildup of fluid like blood.
