Question

What are the clinical features of Beck's triad?

1) Hypotension, muffled heart sounds, and distended neck veins
2) Chest pain, dyspnea, and palpitations
3) Fever, cough, and fatigue
4) Nausea, vomiting, and abdominal pain

Answer 1

The clinical features of Beck's triad are hypotension, muffled heart sounds, and distended neck veins. These features are indicative of cardiac tamponade.

Step-by-step explanation:

Beck's triad is a medical term used to describe a set of clinical features that are associated with cardiac tamponade, a condition where fluid accumulates around the heart. The correct answer is option 1) Hypotension, muffled heart sounds, and distended neck veins. Hypotension refers to low blood pressure, which can occur due to decreased cardiac output caused by the pressure of the accumulated fluid. Muffled heart sounds occur because the fluid hampers the transmission of heart sounds, and distended neck veins are a sign of increased venous pressure. These three clinical features help in identifying cardiac tamponade.
