In a patient with pleural effusion and heart failure, which intervention best reduces cardiac workload?

• A. Provide bedside commode for toileting
• B. Increase IV Fluids
• C. Encourage Rapid Ambulation
• D. Place in Trendelenburg Position

Answer: (A)

Reducing cardiac workload in heart failure centers on lowering the heart’s energy demand and limiting preload. A bedside commode for toileting helps because it minimizes the need for the patient to get up and walk to a distant bathroom, reducing exertion and oxygen consumption. This gentle conservation of energy lessens heart rate and myocardial workload, which is especially beneficial when pleural effusion makes breathing harder. In contrast, increasing IV fluids would raise preload and worsen edema, encouraging rapid ambulation would spike energy use and strain the heart, and placing the patient in Trendelenburg increases venous return and preload, potentially worsening cardiac stress.
