Tick the drug, inhibiting oxidative phosphorylation in some species of helminthes:

Correct Answer: A

Rationale: Niclosamide inhibits oxidative phosphorylation by blocking the electron transport chain in helminthes. It disrupts their energy production, leading to paralysis and death. Piperazine acts on GABA receptors, Praziquantel disrupts the parasite's tegument, and Mebendazole inhibits microtubule function. Therefore, Niclosamide is the correct choice for inhibiting oxidative phosphorylation in helminthes.

Correct Answer: B

Rationale: The correct answer is B: Niacin. Niacin can cause hepatotoxicity and exacerbate liver conditions, which would be a concern in this patient. Cholestyramine (A) works in the intestines, Ezetimibe (C) inhibits cholesterol absorption, and Lovastatin (D) inhibits cholesterol synthesis in the liver, none of which are contraindicated in liver conditions.

Correct Answer: C

Rationale: The correct answer is C: Plasminogen activator. Plasminogen activator is responsible for converting plasminogen into active plasmin, which is an essential enzyme in the fibrinolysis process. Plasminase (A) and Plasminogenase (B) are not actual enzymes involved in this conversion. Plasminogen activator inhibitor (D) works to regulate the activity of plasminogen activator, rather than directly converting plasminogen into plasmin.
