DRE Terms – Complete Guide (Questions With
Solutions)
The adjustment of the eyes for viewing at various distances. Meaning the
pupils will automatically constrict as objects move closer and dialate as
objects move further away Right Ans - accommodation reflex
Habitual, psychological, and physiological dependence on a substance beyond
ones voluntary control Right Ans - Addiction
One mechanism of poly drug interaction. For a particular indicator of
impairment, two drugs produce an ? effect if they both affect then indicator
the same way.
Example: cocaine elevates pulse rates and PCP also elevates pulse rates. The
combination produces the ? on pulse rate. Action plus the same action
produces
reinforced action. Right Ans - Additive effect
Nerves that carry messages to the brain, from the various parts of the body,
including notably the sense organs (eyes, ears, etc.). ? nerves are also known
as afferent
nerves. Right Ans - Afferent/Sensory Nerves
A chemical that is found in, and can be physically extracted from, some
substance. For example, morphine is a natural ? of opium. It does not require a
chemical reaction
to produce morphine from opium. Right Ans - Alkaloid
A drug that relieves or allays pain. Right Ans - Analgesic
An ? of a drug is a chemical that is very similar to the drug, both in terms of
molecular structure and in terms of psychoactive effects. For example, the
drug Ketamine is an ? of PCP. Right Ans - ANALOG (of a drug)
A drug that produces a general or local insensibility to pain and other
sensation. Right Ans - ANESTHETIC
,One mechanism of polydrug interaction. For a particular indicator of
impairment, two drugs produce an ? if they affect the indicator in opposite
ways.
For example, heroin constricts pupils while cocaine dilates pupils. The
combination of heroin and cocaine produces an ? on pupil size. Depending on
how much of each drug was taken, and on when they were taken, the suspect's
pupils could be constricted, or dilated, or within the DRE Average range of
pupil size. • Action versus opposite action yields you can't predict the outcome
Right Ans - ANTAGONISTIC EFFECT
An abnormal heart rhythm. Right Ans - ARRHYTHMIA
The strong, elastic blood vessels that carry blood away the heart. Right Ans
- ARTERY
A blocked ability to coordinate movements. A staggering walk and poor
balance may be caused by damage to the brain or spinal cord. This can be the
result of trauma, birth
defect, infection, tumor, or drug use. Right Ans - ATAXIA
A motor nerve that carries messages to the muscles and organs that we do not
consciously control. There are two kinds of ? nerves, the sympathetic nerves
and parasympathetic nerves. Right Ans - AUTONOMIC NERVE
The part of a neuron (nerve cell) that sends out a neurotransmitter. Right
Ans - AXON
The percentage of alcohol in a person's blood. Right Ans - BAC- BLOOD
ALCOHOL CONCENTRATION
The percentage of alcohol in a person's blood as
measured by a breath testing device. Right Ans - BrAC- BRETH ALCOHOL
CONCENTRATION
The force exerted by blood on the walls of the arteries. ? changes
continuously, as the heart cycles between contraction and expansion. Right
Ans - BLOOD PRESSURE
,Abnormally slow heart rate. Right Ans - BRADYCARDIA
Abnormally slow rate of breathing. Right Ans - BRADYPNEA
Grinding the teeth. This behavior is often seen in person who are under the
influence of cocaine or other CNS Stimulants. Right Ans - BRUXISM
This is the drug category that includes marijuana. Marijuana comes primarily
from the leaves of certain species of Cannabis plants that grow readily all over
the temperate
zones of the earth.
Hashish is another drug in this category, and consists of the
compressed leaves from female Cannabis plants.
The active ingredient in both Marijuana and Hashish is a chemical called delta-
9 tetrahydrocannabinol, usually
abbreviated THC. Right Ans - CANNABIS
A metabolite of THC (tetrahydrocannabinol). Right Ans - CARBOXY THC
Abnormal pattern of breathing. Marked by breathlessness and deep, fast
breathing. Right Ans - CHEYNE- STOKES RESPIRATION
A system within the body consisting of the brain, the brain stem, and the
spinal cord. Right Ans - CNS (Central Nervous System)
One of the seven drug categories includes alcohol, barbiturates, antianxiety
tranquilizers, and numerous other drugs. Right Ans - CNS DEPRESSANTS
One of the seven drug categories includes Cocaine, the Amphetamines, Ritalin,
Desoxyn, and numerous other drugs. Right Ans - CNS STIMULANTS
An inflammation of the mucous membrane that lines the inner surface of the
eyelids caused by infection, allergy, or outside factors. May be bacterial or
viral. Persons
suffering from ? may show symptoms in one eye only. This condition is
commonly referred to as "pink eye", a condition that could be mistaken for the
bloodshot
, eyes produced by alcohol or Cannabis. Conjunctiva is the clear membrane of
the sclera (white portion of the eye) and lines the inside of the eyelids and is
made of lymphoid tissue. Conjunctivae refers to both eyes. Conjunctiva is
singular. Right Ans - CONJUNCTIVITIS
The "crossing" of the eyes that occurs when a person is able to focus on a
stimulus as it is pushed slowly toward the bridge of their nose. Right Ans -
CONVERGENCE
Cocaine base, appears as a hard chunk form resembling pebbles or small
rocks. It produces a very intense, but relatively short duration "high". Right
Ans - CRACK/ROCK
A written summary of a person's education, training, experience, noteworthy
achievements and other relevant information about a particular topic.
Right Ans - CURRICULUM VITAE
A manifestation of impairment due to certain drugs, in which the suspect
alternates between periods (or cycles) of intense agitation and relative calm.
For example, sometimes will be observed in persons under the influence of
PCP. Right Ans - CYCLIC BEHAVIOR
A brief state characterized by incoherent excitement, confused speech,
restlessness, and possible hallucinations. Right Ans - DELIRIUM
The part of a neuron (nerve cell) that receives a neurotransmitter. Right
Ans - DENDRITE
The chemical name for Heroin. Right Ans - DIACETYL MORPHINE
The lowest value of blood pressure. The blood pressure reaches its ? value
when the heart is fully expanded, or relaxed. Right Ans - DIASTOLIC
Double vision. Right Ans - DIPLOPIA
One of the seven drug categories. Includes drugs that inhibits pain by cutting
off or disassociating the brain's perception of pain. PCP and its analogs are
considered ? Right Ans - DISSOCIATIVE ANESTHETICS
