Which term refers to an agent that increases urine output?

The term that refers to an agent that increases urine output is "diuretic." Diuretics are commonly utilized in various medical treatments, particularly for managing conditions like hypertension and edema, as they promote the excretion of water and electrolytes through urine. This increased urine production can help reduce fluid overload in the body, which is especially beneficial in patients with heart failure and certain kidney conditions.

In contrast, diaphoresis refers to excessive sweating, which is unrelated to urine output. Tachycardia signifies an increased heart rate, while bradycardia denotes a decreased heart rate; both of these terms pertain to cardiac function rather than renal or urinary function. Therefore, diuretic specifically identifies substances that act on the kidneys to enhance urine flow, making it the appropriate choice in this context.
