Which statement BEST describes congestive heart failure?

Which statement BEST describes congestive heart failure?

• A. Fluid backs up in the lungs or body
• B. Heart is unable to pump effectively
• C. Heart usually becomes enlarged because the heart muscle thickens from working so hard
• D. Arteries become completely occluded

Answer: (B)

Congestive heart failure means the heart isn’t able to pump blood effectively to meet the body’s needs, so forward flow is reduced and pressures back up in the heart and veins. That inability to pump well is the fundamental issue, which is why describing the heart as unable to pump effectively is the best capture of what CHF is. The backup of fluid in the lungs or body is a common consequence of this pumping problem, not the defining problem itself, so it’s a downstream sign rather than the core description. Heart enlargement from thickening can occur with long-term workload, but it’s not universal to CHF and isn’t what CHF is fundamentally about. Arterial occlusion is a different issue entirely (a blockage in the arteries) and does not define congestive heart failure.
