200 Questions and Verified Answers | Drug Recognition
Expert Certification Prep | A+ Graded
1. Describe the primary effects of CNS stimulants such as amphetamines on the
human body.
CNS stimulants induce relaxation and drowsiness in users.
CNS stimulants increase alertness, attention, and energy levels while
decreasing fatigue.
CNS stimulants primarily relieve pain and induce sleep.
CNS stimulants cause hallucinations and altered perceptions.
2. What is the primary purpose of a sphygmomanometer in drug evaluation?
To measure blood pressure
To evaluate heart rate
To assess pupil dilation
To determine body temperature
3. The effect of cocaine is felt the quickest when the drug is
insufflated
orally
injected
smoked
4. If a drug impairs a person's ability to regulate blood pressure, how might this
affect the readings obtained from a sphygmomanometer?
, The readings may be inaccurately high or low due to impaired
physiological responses.
The readings will only show low blood pressure.
The readings will only show high blood pressure.
The readings will remain unaffected regardless of drug impairment.
5. Describe the significance of Carboxy THC in the context of drug evaluation
and recognition.
Carboxy THC is a synthetic form of THC used for medical purposes.
Carboxy THC is a drug that causes immediate impairment.
Carboxy THC is significant as it is a primary metabolite of THC that
indicates prior cannabis use.
Carboxy THC is a substance that enhances the effects of THC.
6. What artery is used to measure blood pressure?
radial
temporal
brachial
axillary
carotid
7. Describe the significance of the diastolic measurement in blood pressure
readings.
The diastolic measurement reflects the heart's pumping action.
The diastolic measurement is always higher than the systolic
measurement.
, The diastolic measurement indicates the pressure in the arteries
when the heart is at rest between beats.
The diastolic measurement is irrelevant to blood pressure assessment.
8. If a law enforcement officer encounters a subject exhibiting symptoms of
CNS stimulant use, which subcategory knowledge would be most critical for
assessing the situation?
Knowledge of opioid classifications.
Knowledge of depressant effects.
Knowledge of hallucinogenic drugs.
Knowledge of the three subcategories of CNS stimulants.
9. What physiological response is assessed alongside pupil reaction during the
direct light check in DRE evaluations?
Accommodation reflex
Rebound Dilation
Indirect light
Pupil size
10. What is the method of cocaine administration that leads to the quickest
onset of effects?
Snorted
Injected
Smoked
Transdermally absorbed
, 11. Describe the role of the pulmonary artery in the circulatory system.
The pulmonary artery carries oxygenated blood from the lungs to the
left atrium.
The pulmonary artery carries deoxygenated blood from the right
ventricle of the heart to the lungs for oxygenation.
The pulmonary artery supplies blood to the heart muscle.
The pulmonary artery connects the aorta to the heart.
12. Describe how a sphygmomanometer is used in the context of drug
recognition evaluations.
A sphygmomanometer is used to measure blood pressure, which
can indicate the physiological effects of drugs on the body.
A sphygmomanometer is used to assess pupil dilation to determine
drug impairment.
A sphygmomanometer is used to measure body temperature in drug
evaluations.
A sphygmomanometer is used to evaluate heart rate changes due to
drug use.
13. What is one classification of Narcotic Analgesics mentioned in the text?
Hallucinogens
Stimulants
Antidepressants
Natural Alkaloids
