Beck's triad signs for suspected cardiac tamponade in the field include which of the following?

• A. Chest pain radiating to the shoulder.
• B. Jugular venous distension, muffled heart sounds, hypotension.
• C. Sharp chest pain with clear lungs.
• D. Fever with productive cough.

Answer: (B)

Beck's triad is the classic clue for cardiac tamponade, reflecting how a pericardial effusion limits the heart’s filling. When the heart can’t fill properly, stroke volume and cardiac output drop, causing hypotension. The backed-up pressure raises the venous pressures, so neck veins become distended (jugular venous distension). The fluid around the heart also dampens heart sounds, making them muffled. Seeing this combination in the field points toward tamponade and requires rapid transport and careful monitoring. The other descriptions don’t fit tamponade as tightly: chest pain radiating to the shoulder suggests ischemia; sharp chest pain with clear lungs points toward a lung issue like pneumothorax; fever with productive cough hints at infection.
