Tick the unwanted effects of indinavir:

Correct Answer: B

Rationale: Step-by-step rationale: 1. Indinavir is a protease inhibitor used to treat HIV. 2. Nephrolithiasis is a known side effect due to indinavir crystal formation in kidneys. 3. Nausea is a common gastrointestinal side effect. 4. Hepatotoxicity is a serious unwanted effect due to liver damage. 5. Hypotension, vomiting, dizziness (Option A) are not associated with indinavir. 6. Peripheral neuropathy, pancreatitis, hyperuricemia (Option C) are not typical side effects of indinavir. 7. Anemia, neutropenia, nausea (Option D) are not specific to indinavir. Summary: - Option B is correct as nephrolithiasis and hepatotoxicity are known side effects of indinavir. - Options A, C, and D are incorrect as they include side effects not typically associated with indinavir.

Correct Answer: A

Rationale: The correct answer is A: Inhibition of carbonic acid dehydration in the tubular lumen. Acetazolamide is a carbonic anhydrase inhibitor that works in the proximal convoluted tubule of the kidney to reduce bicarbonate reabsorption. By inhibiting carbonic anhydrase, it prevents the conversion of carbonic acid to bicarbonate and H+, leading to increased excretion of bicarbonate in the urine. This results in a systemic metabolic acidosis and a diuretic effect. Choices B, C, and D are incorrect because acetazolamide does not directly stimulate bicarbonate reabsorption in the proximal tubule, inhibit Na+ reabsorption in the early distal tubule, or stimulate H+ reabsorption in the proximal tubule. The primary mechanism of action of acetazolamide is through carbonic anhydrase inhibition, leading to its therapeutic effects.
