A 32-year-old male is brought to the emergency department unresponsive. His pupils are pinpoint, respiratory rate is 4 breaths/min, and he has shallow breathing. His skin is cool and clammy. Paramedics report finding drug paraphernalia next to him. What is the most appropriate immediate intervention?
✓ Correct Answer: Option C
The patient's presentation (unresponsiveness, pinpoint pupils, respiratory depression) is classic for opioid overdose. Naloxone is a specific opioid antagonist that can rapidly reverse these effects.
