HSP Equipment Operation & Maintenance 3 — Questions and Answers
Question 1: A psychologist's virtual reality (VR) exposure therapy headset requires regular cleaning between clients. Which method is MOST appropriate for the face cushion?
- Submerge in isopropyl alcohol for 10 minutes
- Wipe with EPA-registered disinfectant wipes rated for soft surfaces or use disposable foam covers (Correct answer)
- Autoclave sterilization after each session
- Use dry paper towels only to avoid moisture damage
Correct answer: Wipe with EPA-registered disinfectant wipes rated for soft surfaces or use disposable foam covers
VR face cushions should be disinfected with EPA-registered wipes safe for foam/fabric surfaces or replaced with disposable covers between clients to prevent cross-contamination.
Question 2: When storing psychological assessment instruments such as the MMPI answer sheets, what environmental condition is MOST important to maintain?
- Freezing temperature to prevent ink fading
- Controlled temperature and low humidity to prevent paper warping and ink degradation (Correct answer)
- Exposure to indirect sunlight for at least 2 hours daily
- Storage in sealed airtight bags with silica gel desiccant only
Correct answer: Controlled temperature and low humidity to prevent paper warping and ink degradation
Paper-based psychological test materials should be stored in a climate-controlled environment with low humidity to preserve integrity and prevent degradation.
Question 3: A psychologist discovers that the norms for a computerized neuropsychological battery are based on a software version that is two generations behind. What is the MOST appropriate action?
- Continue using the current version as norms rarely change
- Update the software and confirm that updated normative data are applied to all future reports (Correct answer)
- Switch to a paper-based equivalent immediately
- Manually adjust scores by adding 5 points per outdated norm year
Correct answer: Update the software and confirm that updated normative data are applied to all future reports
Using outdated normative databases undermines the validity of neuropsychological interpretations; updating the software ensures that scores are compared against appropriate reference populations.
Question 4: During a biofeedback session, a client complains of a mild skin irritation under the electrode site. What should the psychologist do FIRST?
- Increase the electrical signal to override skin resistance
- Remove the electrode, inspect the skin, and document the adverse reaction (Correct answer)
- Apply more electrode gel to soothe the irritation
- Continue the session while noting the complaint in post-session records
Correct answer: Remove the electrode, inspect the skin, and document the adverse reaction
Client safety requires immediate electrode removal and skin inspection; the reaction must be documented in case it represents a contact allergy or improper electrode placement.
Question 5: What is the PRIMARY purpose of performing an impedance check before an EEG recording session?
- To verify the client's neurological baseline
- To ensure electrode-to-scalp contact is within acceptable resistance ranges for clean signal acquisition (Correct answer)
- To test the amplifier's frequency response
- To confirm the recording software license is active
Correct answer: To ensure electrode-to-scalp contact is within acceptable resistance ranges for clean signal acquisition
Impedance checks confirm that electrode-skin resistance is low enough (typically <5 kΩ) to allow artifact-free neural signal recording.
Question 6: A clinic's psychological testing computers are scheduled for software updates. When is the SAFEST time to perform these updates?
- During active client sessions to use downtime between tests
- During scheduled downtime outside of client testing hours (Correct answer)
- Immediately before a full testing day to ensure the latest version
- Only when a software error occurs during testing
Correct answer: During scheduled downtime outside of client testing hours
Software updates should be performed during scheduled non-testing periods to prevent session interruptions, potential data corruption, or assessment invalidation.
Question 7: A psychologist uses a heart rate variability (HRV) monitor in therapy. The device manual states a maximum storage temperature of 95°F (35°C). Where should the device be stored?
- In a locked car trunk for security
- In a climate-controlled office storage cabinet away from direct sunlight (Correct answer)
- On a windowsill with ambient natural light
- In a sealed plastic bag in the waiting room
Correct answer: In a climate-controlled office storage cabinet away from direct sunlight
Storing the device in a temperature-controlled environment prevents heat-related battery degradation, sensor damage, and firmware corruption.
