In healthcare, which of the following terms describes a weakened heart that cannot pump effectively?

• A. Cardiac Arrest
• B. Arrhythmia
• C. Congestive Heart Failure
• D. Myocardial Infarction

Answer: (C)

Congestive Heart Failure (CHF) is the term that describes a condition in which the heart is weakened and unable to pump blood effectively to meet the body’s needs. This specific dysfunction leads to a buildup of fluid in the lungs and other tissues because the heart cannot maintain adequate circulation. In patients with CHF, symptoms may include shortness of breath, swelling in the legs, and fatigue, all stemming from the heart's inability to function properly.

The other terms relate to different heart conditions. Cardiac arrest refers to the sudden cessation of heart function, necessitating immediate intervention, while arrhythmia signifies abnormal heart rhythms, which do not directly suggest a weakened heart. Myocardial infarction, commonly known as a heart attack, occurs when there is a blockage in the coronary arteries, preventing blood flow, which can lead to damage to part of the heart but does not inherently imply that the heart is weakened in terms of its pumping ability long-term, as seen in CHF.
