DRE DRE Field Sobriety & Vital Signs

Question 1

Which three standardized field sobriety tests (SFSTs) are validated by NHTSA for detecting alcohol impairment?

Accepted Answer

HGN, Walk-and-Turn, One-Leg Stand

Answer

NHTSA validates the Horizontal Gaze Nystagmus (HGN), Walk-and-Turn (WAT), and One-Leg Stand (OLS) as the standardized battery for alcohol impairment detection.

Question 2

During the DRE 12-step protocol, vital signs are measured including pulse rate. What is the normal resting adult pulse range?

Accepted Answer

60–100 bpm

Answer

A normal adult resting pulse rate is 60–100 beats per minute; values outside this range may indicate drug influence on the autonomic nervous system.

Question 3

An elevated body temperature above 99°F (37.2°C) in a DRE evaluation is most consistent with which drug category?

Accepted Answer

CNS stimulants

Answer

CNS stimulants such as methamphetamine and cocaine raise core body temperature (hyperthermia) through increased metabolic activity and sympathetic stimulation.

Question 4

What does the Modified Romberg Balance test primarily assess in a DRE evaluation?

Accepted Answer

Internal time estimation and balance

Answer

The Modified Romberg Balance test assesses a subject's sense of balance and their ability to estimate 30 seconds, both of which can be impaired by drugs.

Question 5

During the DRE muscle tone assessment, CNS depressants typically produce which finding?

Accepted Answer

Flaccid (loose) muscle tone

Answer

CNS depressants relax muscle activity, resulting in flaccid or reduced muscle tone that a DRE can detect through passive movement of the limbs.
