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

• A. Hypertension
• B. Beck's triad
• C. Pulmonary edema
• D. JVD

Answer: (B)

Observation of Beck's triad is essential after pacemaker placement because it signals cardiac tamponade, a life-threatening complication in the immediate postprocedure period. Tamponade occurs when blood or fluid accumulates in the pericardial space, compressing the heart and impairing its ability to fill, which rapidly drops cardiac output. Beck's triad—hypotension, distended neck veins, and muffled heart sounds—collectively points to this condition. In contrast, hypertension or pulmonary edema suggest other issues, and jugular venous distention alone isn’t as specific as the full triad. Prompt recognition of the triad leads to urgent assessment and intervention.
