True or false: Thiazide diuretics are used only for substantial fluid overload, not for hypertension.

True or false: Combining diuretics can increase diuresis without increasing the risk of electrolyte disturbances or kidney injury.

A patient with heart failure develops worsening peripheral edema and pulmonary congestion. Which diuretic class is commonly used for prompt, substantial fluid removal?
