Which term is associated with ketones in medical terminology?

The term associated with ketones in medical terminology is "ket/o." The prefix "ket/o" specifically refers to ketones, which are organic compounds produced during the breakdown of fats when glucose is in short supply in the body, such as during fasting or low-carbohydrate diets. Ketones are often measured to monitor conditions like diabetic ketoacidosis or to assess metabolic states in patients.

In contrast, the other terms focus on different medical contexts: "irid/o" relates to the iris of the eye; "kal/i" is associated with potassium levels in the body; and "ischi/o" refers to the ischium, a part of the pelvis. Each of these terms pertains to distinct anatomical or physiological concepts, making "ket/o" the clear choice for indicating the presence of ketones.
