What does a toxic effect refer to?

A toxic effect refers to a situation where an excessive amount of a medication is absorbed by the body, leading to harmful or adverse effects. This can occur when the dosage exceeds the therapeutic range, resulting in potential damage to organs or bodily functions. Understanding toxic effects is crucial for safe medication administration, as it emphasizes the importance of adhering to prescribed dosages and monitoring patients for signs of toxicity.

The other choices describe different scenarios that do not align with the definition of toxic effects. An expected therapeutic effect represents a positive outcome anticipated from a medication. A beneficial side effect, while being an additional positive outcome, is still not an overdose situation. A common side effect of chronic illness pertains to the natural consequences of ongoing health issues rather than the negative results from medication excess.
