Question

you are called to treat a patient with a suspected narcotic overdose. you should be alert for which of the following?

hallucinations.
allergic reaction.
hypertensive crisis.
respiratory depression.

Explanation:

Identify the drug class and its physiological effects

The question asks about a patient with a suspected narcotic (opioid) overdose. Narcotics are central nervous system (CNS) depressants that bind to mu-opioid receptors in the brain.

Analyze the clinical presentation of opioid toxicity

Using the Toxicological Emergencies knowledge point, we evaluate the classic opioid toxidrome. This toxidrome is characterized by a triad of symptoms:

1. Central nervous system depression (altered mental status or coma)
2. Miosis (pinpoint pupils)
3. Respiratory depression (decreased respiratory rate and tidal volume)

Evaluate the given multiple-choice options

• Hallucinations: More commonly associated with hallucinogens (like LSD) or sympathomimetics, not classic narcotic overdoses.
• Allergic reaction: While possible with any substance, it is not the primary, expected life-threatening effect of a narcotic overdose.
• Hypertensive crisis: Narcotics cause vasodilation and hypotension, not severe hypertension.
• Respiratory depression: This is the most critical, life-threatening effect of narcotic toxicity due to direct suppression of the respiratory center in the brainstem.

Answer:

• Hallucinations.
• Allergic reaction.
• Hypertensive crisis.
• Respiratory depression. (Correct answer)
