Final answer:
Thiazide diuretics work in the distal convoluted tubule to prevent reabsorption of sodium and are commonly used to treat hypertension.
Step-by-step explanation:
The class of diuretics that work by preventing the reabsorption of sodium in the distal convoluted tubule of the kidney are known as thiazide diuretics. These medications help to treat hypertension by blocking the sodium-chloride transporter in the distal convoluted tubule, which ultimately diminishes the reabsorption of sodium and thus increases the excretion of water, leading to increased urine output. It is important to note that while loop diuretics also promote diuresis by inhibiting the reabsorption of sodium and chloride ions, they act in the ascending limb of the loop of Henle, not in the distal convoluted tubule.
