ABMDI Toxicology and Drug-Related Deaths 2 — Questions and Answers
Question 1: A decedent is found with needle marks in the antecubital fossa, drug paraphernalia nearby, and bluish discoloration of the lips. Which immediate cause of death does this scenario most suggest?
- Cardiac arrhythmia due to hypertension
- Opioid intoxication with respiratory depression (Correct answer)
- Hypoglycemia
- Alcohol-related liver failure
Correct answer: Opioid intoxication with respiratory depression
The combination of injection sites, drug paraphernalia, and cyanosis (bluish lips) is a classic presentation of opioid-induced respiratory depression and hypoxia.
Question 2: What is 'excited delirium' and why is it relevant to medicolegal death investigation?
- A postmortem finding seen only in cold environments
- A syndrome of extreme agitation, hyperthermia, and altered mental status often associated with stimulant use or restraint deaths (Correct answer)
- A psychiatric diagnosis used to classify suicides
- A legal defense used in drug-related cases
Correct answer: A syndrome of extreme agitation, hyperthermia, and altered mental status often associated with stimulant use or restraint deaths
Excited delirium is a controversial syndrome characterized by agitation, hyperthermia, and physiological collapse, often associated with stimulant intoxication or in-custody deaths.
Question 3: In a suspected alcohol-related death, which organ is most commonly examined for chronic changes consistent with long-term alcohol abuse?
- Lungs
- Liver (Correct answer)
- Brain
- Kidneys
Correct answer: Liver
The liver shows characteristic pathological changes from chronic alcohol abuse including fatty change, hepatitis, and cirrhosis, making it the primary organ evaluated.
Question 4: What is the significance of finding 'track marks' at a death scene in terms of investigative conclusions?
- They definitively prove the cause of death was a drug overdose
- They indicate a history of intravenous drug use, which provides investigative context but does not alone establish cause of death (Correct answer)
- They are only relevant if the decedent has a criminal record
- They indicate the decedent was a medical professional
Correct answer: They indicate a history of intravenous drug use, which provides investigative context but does not alone establish cause of death
Track marks document a history of IV drug use and provide important investigative context, but toxicology and autopsy findings are required to establish cause of death.
Question 5: Which of the following best describes a 'polypharmacy' death?
- A death caused by an allergic reaction to a single medication
- A death resulting from the combined toxic effect of multiple drugs, none of which alone reached a lethal level (Correct answer)
- A death caused by a pharmacy dispensing error
- A death in which no drugs are found at autopsy
Correct answer: A death resulting from the combined toxic effect of multiple drugs, none of which alone reached a lethal level
Polypharmacy deaths involve synergistic toxicity from multiple substances that collectively cause death even when each individual drug is below a classically lethal threshold.
Question 6: When collecting blood at autopsy for toxicology, why is femoral blood preferred over cardiac blood as the primary specimen?
- Femoral blood is easier to collect
- Femoral blood is less affected by postmortem redistribution from organ drug concentrations (Correct answer)
- Femoral blood contains more red blood cells
- Femoral blood clots faster, preserving the sample
Correct answer: Femoral blood is less affected by postmortem redistribution from organ drug concentrations
Femoral blood is the preferred toxicology specimen because its peripheral location makes it less susceptible to postmortem redistribution from organ drug concentrations.
