A patient returns to the ICU after a permanent pacemaker was inserted. Which finding should the nurse observe for during the immediate hours after insertion?

• A. Beck's triad
• B. Cushing's triad
• C. Homan's sign
• D. Cullen's sign

Answer: (A)

The issue being tested is recognizing tamponade physiology after a cardiac procedure. After a permanent pacemaker is placed, a complication to watch for in the immediate hours is pericardial tamponade from bleeding or a small perforation, which reduces the heart’s ability to fill and pump effectively. The classic finding associated with tamponade is Beck’s triad: hypotension, jugular venous distention, and muffled heart sounds. This combination reflects impaired venous return and decreased cardiac output from the fluid-filled pericardial sac compressing the heart. In practice, the nurse should monitor for sudden drops in blood pressure, a rise in neck vein distention, and muffled or distant heart tones, along with tachycardia and shortness of breath. If these signs appear, it’s a medical emergency requiring immediate evaluation and management. The other options don’t fit this scenario: Cushing’s triad indicates increased intracranial pressure (hypertension, bradycardia, irregular respirations); Homan’s sign suggests deep vein thrombosis; Cullen’s sign points to intra-abdominal bleeding.
