Question 1 of 5
What likely contributed to furosemide-induced metabolic alkalosis in the 47-year-old woman with metastatic breast cancer?
Correct Answer: D
Rationale: The correct answer is D: Decreased reabsorption of Ca2+ in the loop of Henle. Furosemide is a loop diuretic that inhibits the Na+/K+/2Cl- co-transporter in the thick ascending limb of the loop of Henle, leading to decreased reabsorption of Na+ and Ca2+. This leads to an increase in the excretion of Ca2+ in the urine, resulting in metabolic alkalosis due to loss of H+ ions in exchange for Na+ and Ca2+. A: Increased reabsorption of uric acid is not directly related to furosemide-induced metabolic alkalosis. B: Increased delivery of Na+ to the distal tubule would lead to increased reabsorption of Na+ and water, which would not result in metabolic alkalosis. C: Mild inhibition of carbonic anhydrase would not directly cause furosemide-induced metabolic alkalosis.
