DRE Evaluation Procedures 4

Question 1

A DRE subject's nasal area shows redness and irritation, and their speech is slurred and thick-tongued. Which drug category MOST fits this presentation?

Accepted Answer

Inhalants

Answer

Inhalants commonly cause nasal and oral irritation along with slurred speech due to the volatile solvents inhaled through the nose and mouth.

Question 2

Under IACP DRE standards, what is the minimum number of HGN clues (out of 6) that must be present to consider HGN a positive indicator of impairment?

Accepted Answer

4

Answer

NHTSA/IACP standards indicate that four or more HGN clues out of a possible six are a reliable indicator of impairment.

Question 3

When a DRE subject exhibits droopy eyelids (ptosis), slow and slurred speech, and very constricted pupils, which drug category is MOST implicated?

Accepted Answer

Narcotic analgesics

Answer

Narcotic analgesics classically cause ptosis, slow speech, and miosis (very constricted pupils) due to opioid receptor activation.

Question 4

The DRE protocol requires that blood pressure be measured in which unit of measurement?

Accepted Answer

Millimeters of mercury (mmHg)

Answer

Blood pressure is measured and recorded in millimeters of mercury (mmHg), expressed as systolic over diastolic (e.g., 120/80 mmHg).

Question 5

A subject evaluated by a DRE displays open-eye nystagmus (the eyes oscillate spontaneously without stimulus). This finding is MOST associated with:

Accepted Answer

Phencyclidine (PCP)

Answer

Spontaneous or resting nystagmus—eyes jerking without any stimulus—is a hallmark indicator of phencyclidine (PCP) and other dissociative anesthetics.
