Why is weight monitoring recommended for HF patients?

• A. To detect changes in volume status.
• B. To monitor protein intake.
• C. To diagnose arrhythmias.
• D. To measure blood pressure.

Answer: (A)

Weight monitoring is a practical way to gauge changes in fluid status in heart failure. In heart failure, fluid retention tends to rise when the heart isn’t pumping effectively, so even small increases in total body water show up as weight gain. Tracking daily weights helps detect early decompensation before symptoms worsen, allowing timely adjustments to diuretics, diet (like sodium restriction), or other treatments to prevent hospitalizations. For reliable data, weigh yourself at the same time each day (ideally in the morning after voiding and with similar clothing). A rapid weight increase—around 2–3 pounds in a day or about 5 pounds in a week—can indicate fluid overload and should prompt a medical check. Other options focus on nutrition, rhythm assessment, or blood pressure and don’t directly reflect fluid changes, which is why weight is the recommended measure for this purpose.
