Final answer:
Activated charcoal is used to treat certain types of poisoning or drug overdose and would be appropriate in the case of a recent overdose of digitalis (Digoxin). It should be administered promptly after the ingestion of the poisonous substance.
Step-by-step explanation:
In the context of medicine, activated charcoal is often used in the treatment of certain types of poisoning or drug overdose. The administration of activated charcoal would be appropriate in a situation such as an overdose of digitalis (Digoxin) if taken 30 minutes earlier, as mentioned in option A. This is because activated charcoal can bind to the drug in the stomach, preventing it from being absorbed into the bloodstream, thereby limiting the drug's effect on the body. It is, however, important to note that activated charcoal must be given promptly (typically within one hour of ingestion) because its ability to bind decreases as time passes and the substance is absorbed into the stomach or intestines.
