Explain the term "adverse drug reaction."

• A. A beneficial reaction from a medication
• B. An expected response to medication
• C. An unexpected and harmful reaction from medication
• D. A reaction that occurs only in children

Answer: (C)

An adverse drug reaction refers to an unexpected and harmful response that occurs following the administration of a medication. This definition highlights the key components of adverse drug reactions: they are both unexpected, meaning they do not match the anticipated effects of the medication, and harmful, indicating that they can lead to injury or discomfort for the patient. Such reactions can vary in severity and may require medical intervention. This phenomenon emphasizes the importance of monitoring patients for any unexpected side effects when medications are prescribed, as these can impact treatment outcomes and overall patient safety. It also distinguishes adverse drug reactions from intended therapeutic effects or benign side effects, which are fully expected and typically do not pose significant risks.
