Question

The nurse is evaluating the condition of a client after pericardiocentesis performed to treat cardiac tamponade. Which observation would indicate that the procedure was unsuccessful?

1.Rising blood pressure
2.Clearly audible heart sounds
3.Client expressions of relief
4.Rising central venous pressure

Answer 1

A rising central venous pressure indicates that pericardiocentesis was unsuccessful in treating cardiac tamponade, as it suggests persistent pressure in the pericardial cavity affecting cardiac function.

Step-by-step explanation:

The student is asking about the indicators that would suggest an unsuccessful procedure of pericardiocentesis for treating cardiac tamponade. Of the options listed, a rising central venous pressure would be a sign that the procedure was unsuccessful. Pericardiocentesis is intended to remove excess fluid from the pericardial cavity, thereby relieving pressure on the heart and improving heart function. A rising central venous pressure indicates that venous blood is having difficulty returning to the heart due to ongoing pressure in the pericardial cavity, suggesting that fluid remains and is still impairing cardiac function despite the attempt at drainage. In contrast, rising blood pressure, clearly audible heart sounds, and expressions of relief by the client typically indicate a successful resolution of cardiac tamponade symptoms following pericardiocentesis.
