Which of the following is a physical sign of opioid overdose?

• A. Dilated pupils
• B. Slow breathing
• C. Increased heart rate
• D. Heightened reflexes

Answer: (B)

Slow breathing is a significant physical sign of opioid overdose. Opioids depress the central nervous system, which can lead to respiratory depression, significantly slowing down the respiration rate. This can become life-threatening if it progresses to inadequate breathing or apnea, emphasizing the critical nature of monitoring respiratory function in individuals suspected of an opioid overdose. Understanding the other options provides further context. Dilated pupils are typically associated with stimulant use or withdrawal from opioids rather than overdose. Increased heart rate can occur as a reaction to stress but is not a primary indicator of opioid overdose. Heightened reflexes are more indicative of withdrawal symptoms or stimulant use and are not aligned with the effects of opioids, which generally suppress neurophysiological responses.
