In COPD with cor pulmonale, diuretics are used to manage what condition?

• A. Fluid overload
• B. Infection
• C. Airway obstruction
• D. Hypoxemia

Answer: (A)

In COPD with cor pulmonale, diuretics are used to manage fluid overload. The disease process often leads to pulmonary hypertension and right heart strain, causing right-sided heart failure with systemic venous congestion. That results in edema, ascites, hepatomegaly, and pleural or pericardial effusions. Diuretics help reduce the excess fluid by increasing urine output, which lowers preload and eases edema and congestion. They don’t treat the underlying infection, airway obstruction, or hypoxemia themselves, which require separate therapies (antibiotics, bronchodilators/steroids, oxygen). When using diuretics, monitor electrolytes, kidney function, and volume status, and use caution to avoid dehydration or significant electrolyte disturbances.
