Drug toxicology Questions
Question 1 of 5
The following suspected overdoses are indications for emergency measurement of drug concentration:(Select one that does not apply)
Correct Answer: C
Rationale: Iron (A), methanol (B), and salicylates (E) require emergency concentration measurement due to specific treatments (e.g., deferoxamine, ethanol, alkalinization). Amitriptyline (C) and temazepam (D) are managed symptomatically.
Question 2 of 5
The following are clinical signs consistent with heroin (diamorphine) intoxication:(Select one that does not apply)
Correct Answer: B
Rationale: Heroin intoxication causes hypothermia (C), pinpoint pupils (D), and slurred speech (E). Hypertension (A) and rapid respiratory rate (B) are not typical; instead, hypotension and respiratory depression occur.
Question 3 of 5
Specific causes of death which are positively related to smoking include:
Correct Answer: D
Rationale: Smoking is a known risk factor for ischaemic heart disease (A), oesophageal cancer (B), emphysema (C), aortic aneurysm (D), and tongue cancer (E), all well-documented in toxicology.
Question 4 of 5
Ethyl alcohol (ethanol):(Select one that does not apply)
Correct Answer: D
Rationale: Ethanol is mostly absorbed in the small intestine (A), delays gastric emptying (B), and 95% is metabolized (C). D is incorrect as ethanol follows zero-order kinetics at typical concentrations, and E’s ranking varies by region and data.
Question 5 of 5
Delirium tremens:
Correct Answer: B
Rationale: Delirium tremens has a 5-10% mortality rate (B) and requires parenteral thiamine (D) to prevent Wernicke’s encephalopathy. A is incorrect (only ~5% of withdrawals), C is wrong (benzodiazepines are the treatment), and E is unnecessary (phenytoin isn’t standard prophylaxis).
