✍️ Sample DRE Questions & Answers
1. Why are vital signs recorded during the DRE evaluation?
Vital signs, including pulse, blood pressure, and body temperature, are recorded during a DRE evaluation because different drug categories have predictable physiological effects on these parameters. For example, stimulants typically elevate pulse and blood pressure, while depressants can lower them. Monitoring these changes helps the DRE correlate observed physical symptoms with specific drug categories to determine impairment.
2. What effect is most commonly associated with narcotic analgesics?
Narcotic analgesics, such as opioids like heroin or fentanyl, are central nervous system depressants. They typically cause miosis, or pinpoint pupils, due to their effect on the oculomotor nerve. Additionally, these drugs significantly depress the respiratory system, leading to a dangerously low breathing rate, which is a primary concern in overdose situations.
3. Which information about vital signs must be documented in the DRE report?
The DRE protocol requires documentation of pulse rate, blood pressure, and body temperature along with the time each measurement was taken.
4. What is the DRE professional's obligation regarding confidentiality?
Confidentiality requires professionals to protect all client information from unauthorized disclosure, sharing only with the client's explicit consent or when required by law (e.g., mandatory reporting of abuse or imminent danger).
5. An elevated body temperature above 99°F (37.2°C) in a DRE evaluation is most consistent with which drug category?
CNS stimulants such as methamphetamine and cocaine raise core body temperature (hyperthermia) through increased metabolic activity and sympathetic stimulation.
6. Chain of custody documentation for a DRE urine specimen must include:
Chain of custody documentation must track every person who handled the specimen, all transfer dates and times, and storage conditions to ensure evidentiary integrity.
