In the "FACES" mnemonic, which symptom is associated with heart failure?

• A. Fatigue
• B. Fever
• C. Flushing
• D. Fainting

Answer: (A)

The symptom associated with heart failure in the "FACES" mnemonic is fatigue. Heart failure often leads to decreased cardiac output, which means the body does not receive enough oxygen and nutrients to meet its needs. As a result, individuals may experience extreme tiredness or exhaustion, even with minimal activity. This fatigue is a consequence of the heart being unable to effectively pump blood, leading to insufficient circulation and energy levels.

The other symptoms listed, such as fever, flushing, and fainting, can be indicative of various medical conditions but do not specifically capture the hallmark signs of heart failure as effectively as fatigue does. While fever can point to an infection and flushing may indicate other circulatory issues, neither are primary indicators of heart failure. Fainting can occur in various situations, including hypotension or arrhythmias, but again is not a direct symptom of heart failure. Fatigue succinctly embodies the chronic depletion experienced by patients with this condition.
