Which of the following is a product defect example of adverse events?

• A. Broken product seals
• B. Prescription errors
• C. On-time delivery
• D. Correct labeling

Answer: (A)

The main idea here is that adverse events caused by a product come from problems in the item itself—issues in manufacturing or packaging that could harm someone using it. A broken product seal signals a packaging defect that can compromise safety, such as possible contamination or tampering, which directly makes the product unsafe and capable of causing harm. Prescription errors describe mistakes in how a drug is prescribed or dispensed, which is a process issue rather than a defect in the product. On-time delivery and correct labeling relate to service quality and accurate information, not a defect in the product itself. Therefore, broken product seals are the clear example of a product defect that can lead to adverse events.
