Tick the drug for strongiloidosis treatment:

Correct Answer: D

Rationale: The correct answer is D: Ivermectin. Ivermectin is the drug of choice for strongyloidiasis due to its high efficacy and low toxicity. It works by paralyzing and killing the parasites. Niclosamide (A) is used for tapeworm infections, Praziquantel (B) for schistosomiasis, and Bithionol (C) for fascioliasis. Therefore, D is the correct choice for treating strongyloidiasis.

Correct Answer: C

Rationale: Rationale for Correct Answer C: Furosemide inhibits Na+/K+/2Cl- cotransporter in the loop of Henle, leading to decreased Na+ reabsorption. This results in increased delivery of Na+ to the distal tubule, stimulating H+ secretion and bicarbonate reabsorption, causing metabolic alkalosis. Mild inhibition of carbonic anhydrase by furosemide also contributes by reducing H+ secretion in the proximal tubule. Summary of Incorrect Choices: A: Increased reabsorption of uric acid is not directly related to furosemide-induced metabolic alkalosis. B: Increased delivery of Na+ to the distal tubule is a consequence of furosemide action but does not directly contribute to metabolic alkalosis. D: Decreased reabsorption of Ca2+ in the loop of Henle may lead to hypocalcemia but is not a direct cause of metabolic alkalosis in this case.
