Question 1

Which component of a spectrophotometer converts electromagnetic radiation into an electrical signal?

A. Recorder

B. Sample holder

C. Monochromator

D. Detector

Answer 1

Detector

Question 2

What is a detector?

Answer 2

The sample holder holds the sample, while the detector in a spectrophotometer converts radiation into an electrical signal for analysis. It plays a crucial role in measuring light intensity.

Question 3

Which term describes the state where an individual experiences physical discomfort and distress upon reducing or stopping drug use after prolonged exposure?

A. Relapse Prevention

B. Tolerance Development

C. Withdrawal Sickness

D. Addiction Cycle

Answer 3

C. Withdrawal Sickness

Question 4

What is relapse prevention?

Answer 4

Relapse Prevention focuses on avoiding returning to drug use.

Question 5

What is withdrawal sickness.

Answer 5

Withdrawal Sickness refers to the physical discomfort when reducing or stopping drug use after prolonged exposure.

Question 6

What is the purpose of a detector in gas chromatography?

A. To separate components in the column

B. To develop signals that activate the recorder for making a permanent record of separation

C. To introduce the sample into the column

D. To heat the injection chamber

Answer 6

B. To develop signals that activate the recorder for making a permanent record of separation

Question 7

Which regulatory body in the United States is responsible for enforcing the Controlled Substances Act and regulating the manufacturing, distribution, and dispensing of controlled substances?

A. National Institutes of Health (NIH)

B. Centers for Disease Control and Prevention (CDC)

C. Food and Drug Administration (FDA)

D. Drug Enforcement Administration (DEA)

Answer 7

Drug Enforcement Administration (DEA)

Question 8

What is the DEA?

Answer 8

The Food and Drug Administration (FDA) focuses on drug safety and approval, not enforcement of controlled substances. The Drug Enforcement Administration (DEA) enforces the Controlled Substances Act.

Question 9

What allows gas chromatography to rapidly separate complex mixtures into individual compounds?

A. Nitrogen gas flow through the injector

B. Heated injection chamber

C. Carrier gas

D. Thin film of liquid in the column

Answer 9

Thin film of liquid in the column

Question 10

What is gas chromotography?

Answer 10

Nitrogen gas flow through the injector helps vaporize samples, not separate compounds. Gas chromatography separates mixtures using a thin film of liquid in the column, allowing for rapid separation.

Question 11

Under which legislation does Canada regulate the possession, production, and distribution of controlled substances?

A. Health Canada Regulations Act

B. Controlled Drugs and Substances Act

C. Canadian Food and Drugs Act

D. Canada Narcotic Control Act

Answer 11

Controlled Drugs and Substances Act

Question 12

What type of drugs are known for their ability to alter perception, mood, and cognitive processes, leading to hallucinations and changes in thought patterns?

A. Hallucinogens

B. Club Drugs

C. Synthetic Opiates

D. Narcotics

Answer 12

Hallucinogens

Question 13

In gas chromatography, what role does the recorder play in the analysis process?

A. It makes a permanent record of the separation by tracing peaks on the chromatograph

B. It separates the components of the sample

C. It identifies the concentration of each compound

D. It introduces the sample into the column

Answer 13

It makes a permanent record of the separation by tracing peaks on the chromatograph

Question 14

What does the recorder do in GC?

Answer 14

The recorder in gas chromatography does not identify compound concentrations. Its role is to create a permanent record by tracing peaks on the chromatograph for analysis.

Question 15

Which category of drugs acts to slow down the central nervous system and reduce brain activity?

A. Stimulants

B. Hallucinogens

C. Anabolic Steroids

D. Depressants

Answer 15

D. Depressants

Question 16

What factors contribute to the psychological dependence associated with drug dependence?

A. Genetic predisposition

B. Social environment influences

C. Emotional and behavioral aspects

D. Physical symptoms only

Answer 16

C. Emotional and behavioral aspects

Question 17

What is the purpose of classifying drugs into different schedules under the Controlled Substances Act?

A. To regulate the potential for abuse and dependency

B. To determine the color of pill capsules

C. To control the cost of prescription medications

D. To standardize drug packaging

Answer 17

A. To regulate the potential for abuse and dependency

Question 18

How does the monochromator or frequency selector contribute to the function of a spectrophotometer?

A. It disperses radiation into component wavelengths

B. It converts electromagnetic radiation into an electrical signal

C. It selects specific wavelengths of radiation for analysis

D. It holds the sample being analyzed

Answer 18

C. It selects specific wavelengths of radiation for analysis

Question 19

What is the purpose of the detector in gas chromatography?

A. To identify separated components and generate signals for the recorder

B. To produce a permanent record of the separation

C. To introduce the sample into the column

D. To heat the sample and injector chamber

Answer 19

A. To identify separated components and generate signals for the recorder

Question 20

What characterizes physical dependence in the context of drug addiction?

A. Improved emotional regulation

B. Enhanced cognitive functions

C. Increased social interactions

D. Development of tolerance and withdrawal symptoms

Answer 20

D. Development of tolerance and withdrawal symptoms

Which class of drugs is characterized by their ability to increase alertness, attention, and energy levels in individuals?

A. Depressants

B. Stimulants

C. Anabolic Steroids

D. Synthetic Opiates

Answer 21

B. Stimulants
