Florida State Paramedic Practice Exam

Which combination of signs is part of Beck's Triad?

1. High blood pressure, JVD, Clear lungs

2. Narrowed pulse pressure, JVD, Muffled heart tones

3. Normal pulse pressure, JVD, Absent heart sounds

4. Low blood pressure, Edema, Clear lungs

The correct answer is: Narrowed pulse pressure, JVD, Muffled heart tones

Beck's Triad is a clinical syndrome primarily associated with cardiac tamponade and consists of three specific signs: narrowed pulse pressure, jugular vein distension (JVD), and muffled heart tones. This combination provides crucial insights into the hemodynamic status of a patient experiencing cardiac tamponade, which occurs when fluid accumulates in the pericardial space, exerting pressure on the heart and impairing its ability to pump effectively. Narrowed pulse pressure indicates a decreased difference between systolic and diastolic blood pressure, suggesting compromised heart function and inadequate stroke volume. Jugular vein distension occurs as fluid backs up due to increased right atrial pressure, a direct result of the impaired venous return to the heart. Muffled heart tones occur during auscultation due to the presence of fluid in the pericardial space, which dampens the sounds generated by the heart. This triad is instrumental for paramedics and emergency providers, as recognizing these signs can lead to prompt diagnosis and management in critical situations involving cardiac complications.
