Bounding pulses may be present in which condition?

Bounding pulses may be present in which condition?

• A. Sepsis
• B. Hypovolemia
• C. Fluid overload
• D. Cardiac tamponade

Answer: (C)

A bounding pulse happens when the heart ejects a large volume of blood into arteries that are highly compliant, producing a strong, rapid upstroke and a wide pulse pressure. This is most typical in fluid overload (hypervolemia), where excess intravascular volume increases venous return and stroke volume, yielding a full, forceful pulse that can be easily felt and may fade quickly with each beat. In contrast, low blood volume (hypovolemia) usually causes a weak, thready pulse; cardiac tamponade often presents with a weak pulse and pulsus paradoxus; sepsis can sometimes cause a bounding pulse due to high cardiac output, but the classic association in this context is with fluid overload. Therefore, bounding pulses align with fluid overload.
