Which category accelerates intestinal transit to eliminate poisons?

Activated charcoal Urine alkalinization Hemodialysis Cathartics

Correct Answer:

Cathartics

Explanation:

Accelerating intestinal transit to remove ingested poisons relies on speeding up gut movement so the toxin spends less time in the absorptive lining and is expelled more quickly. Cathartics provoke bowel movements and increase the speed of GI transit, helping eliminate poisons that remain in the gut or are not yet absorbed. Activated charcoal, by contrast, works through adsorption—binding toxins in the GI tract to prevent absorption—rather than speeding up transit. Urine alkalinization and hemodialysis remove toxins through the kidneys or directly from the blood, not by increasing GI motility. So the option that best fits the idea of hastening elimination by moving contents through the intestines is cathartics.
