Which of the following is a sign of benzodiazepine overdose?

Respiratory depression is a hallmark sign of benzodiazepine overdose. Benzodiazepines are central nervous system depressants that can significantly reduce the respiratory drive, leading to inadequate breathing or apnea in severe cases. This can be particularly dangerous, as it may result in decreased oxygenation and could be life-threatening.

While other symptoms can accompany benzodiazepine overdose, respiratory depression stands out due to its potential to cause immediate and severe complications. It is crucial for healthcare providers to recognize this sign and respond promptly by providing supportive care, which may include airway management and respiratory support.
