Forensic Science: Drugs and Toxicology Review

Front

What are the stages of alcohol metabolism?

Back

The stages of alcohol metabolism include absorption, distribution, and elimination. Ingestion is not considered a stage of metabolism.

Front

What factors influence a person's dependence on a drug?

Back

Factors influencing drug dependence include the type of drug used, the route of administration, and society's attitudes and responses. The synthetic or natural origin of the drug does not influence dependence.

Front

What is a major challenge faced by toxicologists when analyzing evidence?

Back

A major challenge is that few substances enter and leave the body in the same chemical state, making it difficult to determine the exact nature of the drug's effects.

Front

True or False: The role of the forensic toxicologist is limited to matters that pertain to violations of the law.

Back

True.

Front

What does a breath test measure in relation to alcohol?

Back

A breath test measures the alcohol concentration in the pulmonary artery.

Front

Define forensic toxicology.

Back

Forensic toxicology is the study of the effects of drugs and poisons on the human body, particularly in relation to legal cases.

Front

What is the primary purpose of drug screening tests?

Back

The primary purpose of drug screening tests is to quickly identify the presence of drugs in a biological sample.

Front

What is the difference between screening tests and confirmatory tests in toxicology?

Back

Screening tests are preliminary tests that indicate the presence of a substance, while confirmatory tests provide definitive identification of the substance.

Front

What role does the route of administration play in drug effects?

Back

The route of administration affects how quickly and effectively a drug reaches the bloodstream and its overall impact on the body.

Front

What is the significance of the pulmonary vein in alcohol testing?

Back

The pulmonary vein carries oxygenated blood from the lungs to the heart, but alcohol concentration is measured in the pulmonary artery, which reflects the blood coming from the heart to the lungs.
