Write answer in between .Q:A 68-year-old male with congestive heart failure recently had his medication regiment adjusted to better control his hypertension. Three weeks later, laboratory analysis shows his serum calcium and magnesium levels have both decreased. The diuretic used in this patient acts predominantly on which nephron segment:? A: Proximal tubule, B: Descending loop of Henle, C: Thick ascending loop of Henle, D: Distal tubule, E: Cortical collecting duct,  <response>: This is a question about the mechanism of action of diuretics in treating hypertension and congestive heart failure. The patients calcium and magnesium levels decreased after starting a new diuretic medication. This suggests the diuretic is acting on the thick ascending loop of Henle, as this segment is responsible for reabsorption of calcium and magnesium. The choices list different parts of the nephron, so I need to identify which one corresponds to the thick ascending loop of Henle based on the effect seen in the patient.C: Thick ascending loop of Henle
