Which statement best describes the difference between acute and chronic poisoning?

• A. Acute poisoning always has milder symptoms than chronic poisoning.
• B. Acute poisoning results from a single dose; chronic poisoning results from repeated exposure to small doses.
• C. Chronic poisoning results from a single large dose; acute from repeated exposure.
• D. There is no difference between acute and chronic poisoning.

Answer: (B)

The idea being tested is how poisoning is classified by exposure pattern, not just how severe it feels. Acute poisoning is about a single, usually large, dose causing effects that appear quickly, while chronic poisoning comes from repeated exposure to small doses over time, leading to a buildup that can cause illness long after the exposures begin. This is why the best description is that acute poisoning results from a single dose and chronic poisoning results from repeated exposure to small doses. It highlights why management differs: acute cases require rapid response to a sudden crisis, whereas chronic cases focus on reducing ongoing exposure to prevent cumulative harm. The other statements don’t fit because acute exposure can be severe rather than milder, chronic poisoning isn’t driven by a single large dose, and there is a real difference between acute and chronic patterns of exposure.
