Match List I with List II and select the correct answer using the Code given below the lists:
List I (Antidote) List II (Poison/Drug) A Calcium sodium edetate 1 Cyanide B Sodium nitrite 2 Nitrobenzene C Methylene blue 3 Lead D Atropine 4 Organophosphate 5 Kerosene
A-3, B-1, C-2, D-4
Antidote Poison Matching Explained
This question requires matching specific antidotes from List I to their corresponding poisons or drugs listed in List II. Understanding these pairings is crucial for toxicology and emergency medicine.
Key Antidote-Poison Pairings
Based on the provided correct answer, the established pairings are:
- Calcium sodium edetate (A) is correctly matched with Lead (3). This antidote acts as a chelating agent, binding to lead ions to facilitate their excretion from the body, treating lead poisoning.
- Sodium nitrite (B) is correctly matched with Cyanide (1). It is used to treat cyanide poisoning by oxidizing hemoglobin to methemoglobin, which binds cyanide more effectively than hemoglobin.
- Methylene blue (C) is correctly matched with Nitrobenzene (2). Methylene blue is the primary antidote for methemoglobinemia, a condition induced by substances like nitrobenzene where hemoglobin's oxygen-carrying capacity is reduced.
- Atropine (D) is correctly matched with Organophosphate (4). Atropine is a vital medication used to counteract the dangerous overstimulation of the parasympathetic nervous system caused by organophosphates.
Summary of Correct Matches
The correct matching of List I (Antidote) to List II (Poison/Drug) is summarized below:
| Antidote (List I) | Poison/Drug (List II) | Match Number |
| A: Calcium sodium edetate | Lead | 3 |
| B: Sodium nitrite | Cyanide | 1 |
| C: Methylene blue | Nitrobenzene | 2 |
| D: Atropine | Organophosphate | 4 |
This corresponds to option 4, where A=3, B=1, C=2, and D=4.
