A

Average is a quantity that represents the middle or typical value that the majority of healthy, non-impaired people would exhibit or have in a specific test that is measured numerically.

59
Q

Bodily functions examined during drug influence evaluation

60
Q

What acronym is used as a way of discussing human physiology.

MURDERS, INC

61
Q

MURDERS stands for

A 
M = muscular system
U = urinary system
R = Respiratory system
D = Digestive system
E = Endocrine system
R = Reproductive system
S = Skeletal system
62
Q

INC stands for

A 
I = integumentary system
N = nervous system
C = circulatory system
63
Q

Homeostasis is -

A

Dynamic balance, or steady state, involving levels of salts, water, sugars and other materials in the body’s fluids.

64
Q

How do drugs interfere with homeostasis?

A

They interfere with homeostatic mechanisms and produce signs and symptoms that can be recognized by a trained DRE

65
Q

Each neuron has what three main parts?

A

The cell body; the axon; the dendrite.

66
Q

Two classifications of nerves

A

Motor - efferent nerves

Sensory - afferent nerves

67
Q

Sub-system of motor nerves

A

Voluntary nerves - which send messages to the striated muscles that we consciously control.

and

Autonomic nerves - which send messages to the muscles and organs that we do not consciously control.

68
Q

Two nerves in the autonomic sub-system

A

Sympathetic nerves - fight or flight

Parasympathetic nerves - produce relaxed and tranquil activities.

A

In or near the natural crease of the wrist, on the side of the wrist next to the thumb.

71
Q

The Drug Evaluation and Classification Process is a systematic and standardized method of examining a subject to determine?

A
  1. Is the subject impaired?
  2. Is the impairment from an injury, illness or drug related?
  3. If drug related what category(s) of drugs are likely causing the impairment?
72
Q

What do anticholinergic drugs do?

A

They block parasympathetic nerves.

An Anticholinergic drug can look like a sympathomimetic drugs

73
Q

How do dugs work?

A

By artificially creating natural body reactions generally associated with the work of neurotransmitters and hormones.

74
Q

What are three
Neurotransmitters
“Chemical Messengers”

A

Narcotic Analgesics

Vice - versa

78

Tolerance in testing

A

May exhibit relatively little evidence of psychophysical tests.

Even tolerant drug users, when impaired, usually exhibit clinical evidence.

Others - if something is off investigate

84
Q

The functions of the body are controlled by what two systems

A

Nervous and circulatory

85
Q

Explain negative feedback

A

Add later

86
Q

“Normal” definition within the DEC program.

A

Normal describes both a range of values or results that are close to average, but can be above or below the average value for the majority of unimpaired people.

Can used to describe things that do not have a numeric value. Muscle tone.

87
Q

According to 2013-14 study - more than ______ of drivers tested positive for at least one illegal drug, up from _______ in 2007

A

15 %

12 %

88
Q

Los Angeles Field Validation study (1985) discovered two things

A

72% of SUSPECTS had two or more drug categories in them including alcohol

45% had two or more drugs other than alcohol

89
Q

Common drug combinations

A 
Cocaine and Heroin - speedball
PCP and Heroin - Fireball 
Crack and PCP - Space base
Crack and Marihuana- Primo
Crack and Methamphetamine- Croack
90
Q

Null effect

A

No action + no action = no action

91
Q

Overlapping effect

A

Action + no action = action

92
Q

Addictive effect

A

Action + same action = reinforced action

93
Q

Antagonistic effect

A

Action + opposite action = an unpredictable outcome

Whichever Drug is more psychoactive at the time determines what we’ll see.
