Correct answer: B — Call emergency services immediately

Marked drowsiness with respiratory depression suggests opioid toxicity and requires urgent emergency management. In this vignette, "Call emergency services immediately" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
