DRE Risk Assessment & Management 3 — Questions and Answers
Question 1: Under the DRE framework, which drug category poses the greatest risk of lethal hyperthermia combined with cardiovascular collapse?
- Cannabis
- CNS depressants
- CNS stimulants (particularly methamphetamine) (Correct answer)
- Inhalants
Correct answer: CNS stimulants (particularly methamphetamine)
CNS stimulants, especially methamphetamine, can elevate body temperature to fatal levels while simultaneously causing cardiac arrhythmias.
Question 2: A DRE officer is assessing a suspect who is combative and has been restrained in a prone position for 10 minutes. The highest risk from this restraint posture is:
- Increased aggression upon release
- Positional asphyxia leading to death (Correct answer)
- Skin abrasions from ground contact
- Elevated blood pressure only
Correct answer: Positional asphyxia leading to death
Prone restraint restricts chest expansion and diaphragm movement, causing positional asphyxia, especially in excited delirium subjects.
Question 3: Which DRE step most directly assesses risk of CNS stimulant-induced stroke?
- Horizontal gaze nystagmus
- Vital signs (blood pressure measurement) (Correct answer)
- Romberg balance test
- Finger-to-nose test
Correct answer: Vital signs (blood pressure measurement)
Dangerously elevated blood pressure from stimulant use is a primary stroke risk factor, making BP measurement the most direct assessment.
Question 4: When risk-stratifying a DRE subject, which finding is least consistent with low-risk classification?
- Cooperative demeanor and oriented to time and place
- Blood pressure of 182/118 with agitation (Correct answer)
- Slightly elevated pulse of 90 bpm
- Mild nystagmus without other indicators
Correct answer: Blood pressure of 182/118 with agitation
Hypertension above 180/110 combined with agitation represents a medical emergency and cannot be classified as low risk.
Question 5: A DRE candidate learns that dissociative anesthetics like PCP can cause sudden re-emergence reactions hours after initial dosing. This knowledge affects risk management by:
- Indicating the subject can be safely released after initial evaluation
- Requiring extended monitoring and informing custody staff of re-emergence risk (Correct answer)
- Suggesting that PCP evaluations need no vital sign reassessment
- Confirming that only a single urine sample is needed
Correct answer: Requiring extended monitoring and informing custody staff of re-emergence risk
PCP re-emergence can trigger violent or psychotic behavior hours post-dose, so custody staff must be warned and the subject monitored continuously.
Question 6: Which tool does the DRE protocol recommend to objectively document pupil size as part of risk and impairment assessment?
- A standard ruler
- A penlight only
- A pupilometer or pupil size gauge card (Correct answer)
- Digital photography exclusively
Correct answer: A pupilometer or pupil size gauge card
A standardized pupil size gauge card provides objective measurement in millimeters, reducing subjectivity in documentation.
Question 7: During a DRE examination, the subject suddenly loses consciousness. The FIRST action the officer should take is:
- Call the DRE supervisor to document the event
- Complete the blood pressure reading before calling for help
- Check for a pulse and call for emergency medical assistance immediately (Correct answer)
- Secure the evaluation area and wait for the subject to regain consciousness
Correct answer: Check for a pulse and call for emergency medical assistance immediately
Loss of consciousness may signal cardiac arrest or respiratory failure; immediate pulse check and EMS activation are the life-saving priorities.
