Appeared in: ESIC Nursing Officer-7July 2024
Explanation
- Delirium tremens is a symptom of severe alcohol withdrawal, not opioid overdose.
- It is characterized by a hyper-excitable state including agitation, confusion, and hallucinations.
- This contrasts with the classic triad of opioid overdose: CNS depression, respiratory depression, and miosis (pinpoint pupils).
Why Other Options Were Wrong
- Option B: This is a hallmark and the most dangerous symptom of opioid overdose, caused by the suppression of the respiratory centers in the brainstem.
- Option C: Stupor, a state of near-unconsciousness, is a classic sign of the central nervous system (CNS) depression that occurs during an opioid overdose.
- Option D: Coma is a state of profound unresponsiveness and represents the most severe form of CNS depression in an opioid overdose.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Differentiating Symptoms of Opioid Overdose from Other Conditions as background academic context rather than a clinical decision trigger.
- Accurately differentiating between opioid overdose and alcohol withdrawal is critical in emergency settings. Misdiagnosis can lead to incorrect treatment and fatal outcomes. Administering naloxone (for opioid overdose) will have no effect on delirium tremens, and the supportive care for DT (often involving benzodiazepines) is different.
- A key nursing responsibility is to assess an unresponsive patient for the cause. Checking for pinpoint pupils, slow breathing, and needle tracks points towards opioids, while a history of alcoholism and signs of agitation or tremors would suggest alcohol withdrawal.
- What if the patient has both taken opioids and is in alcohol withdrawal? This is a complex and dangerous scenario. The patient might present with mixed or atypical signs. Treatment requires careful management of both conditions, often in an ICU setting, prioritizing airway and breathing (ABCs) first.
How to Approach the Question
- This is an 'EXCEPT' question, which requires you to find the option that does not belong with the others.
- First, identify the core concept in the question stem: 'symptoms of opioids overdose'.
- Review each option to see if it fits the category of an opioid overdose symptom.
- Respiratory depression, stupor, and coma are all well-known signs of the depressant effects of opioids.
- Delirium tremens is the outlier. Recall or determine that it is associated with alcohol withdrawal, which is a state of hyper-excitation, the opposite of an opioid overdose.
- Therefore, Delirium tremens is the correct answer as it is the exception.
