Which statement describes CHF as listed?

• A. Breathlessness, early muscular fatigue, exercise intolerance
• B. Chronic cough and fever
• C. Nausea and vomiting
• D. Headache and dizziness

Answer: (A)

Recognizing the typical symptom pattern of congestive heart failure: breathlessness from fluid backing up into the lungs, combined with early fatigue and limited ability to exercise due to reduced cardiac output. These features reflect how the heart’s diminished pumping capacity affects both breathing and muscle performance during activity. The other options point to conditions or symptoms not specific to CHF—chronic cough with fever suggests infection or inflammation, nausea and vomiting are nonspecific, and headache or dizziness can occur with many problems but aren’t characteristic of CHF.
