The bile acid-binding resins can bind many drugs and vitamins and reduce their absorption. This consideration is:

Correct Answer: A

Rationale: The correct answer is A: TRUE. Bile acid-binding resins can bind to various drugs and vitamins in the gastrointestinal tract, leading to reduced absorption. This occurs due to the resins' ability to form complexes with these substances, preventing their uptake into the bloodstream. This interference can potentially impact the effectiveness of medications or the absorption of essential vitamins. Choices B, C, and D are incorrect because they do not accurately reflect the specific mechanism of action of bile acid-binding resins in drug and vitamin absorption.

Correct Answer: C

Rationale: Rationale: Chronic use of Furosemide can lead to distal tubular hypertrophy, reducing its diuretic effect due to compensatory changes in the nephron function. Furosemide is a loop diuretic acting in the thick ascending limb of the loop of Henle. Acetazolamide is a carbonic anhydrase inhibitor acting in the proximal tubule. Amiloride is a potassium-sparing diuretic acting on the collecting duct. Hydrochlorothiazide is a thiazide diuretic acting in the distal convoluted tubule. Only Furosemide among the options affects the loop of Henle, leading to distal tubular hypertrophy over time.

Correct Answer: B

Rationale: The correct answer is B: Lincomycin. Lincomycin belongs to the lincosamides class of antibiotics, which also includes clindamycin. Lincomycin works by inhibiting bacterial protein synthesis. Erythromycin (A) is a macrolide antibiotic, not a lincosamide. Azithromycin (C) is another macrolide antibiotic. Aztreonam (D) is a monobactam antibiotic, not a lincosamide. Therefore, the correct answer is B because it is the only drug belonging to the lincosamides class.

Correct Answer: B

Rationale: Step 1: Isoniazid is a hydrazide of isonicotinic acid, making it the correct antimycobacterial drug. Step 2: Rifampin is a rifamycin antibiotic, not a hydrazide of isonicotinic acid. Step 3: Ethambutol is an antimycobacterial drug but not a hydrazide of isonicotinic acid. Step 4: Pyrazinamide is an antimycobacterial drug but not a hydrazide of isonicotinic acid.

Correct Answer: A

Rationale: The correct answer is A: Praziquantel. Praziquantel is the drug of choice for treating neurocysticercosis as it is effective against the tapeworm causing this condition. It works by affecting the tapeworm's cell membrane, leading to paralysis and death of the parasite. Pyrantel is used for treating intestinal parasites, not neurocysticercosis. Piperazine is used for treating roundworm infections. Bithionol is used for treating certain types of flukes. Therefore, the most appropriate choice for neurocysticercosis treatment is praziquantel due to its effectiveness against the tapeworm causing the condition.
