RPSGT Best Practices & Methodologies 5

Question 1

During a Multiple Sleep Latency Test (MSLT), nap opportunities are scheduled every how many hours following the termination of the nocturnal PSG?

Accepted Answer

2 hours

Answer

MSLT nap opportunities are scheduled every 2 hours, with the first nap typically beginning 1.5–3 hours after the morning termination of the nocturnal PSG.

Question 2

For pediatric patients (aged 2–13 years), what slow-wave amplitude threshold differs from adult AASM scoring criteria?

Accepted Answer

Children use >50 µV instead of >75 µV for N3 scoring

Answer

Pediatric AASM scoring rules lower the N3 slow-wave amplitude threshold to >50 µV (compared to >75 µV in adults) because children normally generate higher-amplitude slow waves.

Question 3

What infection control measure is required between patients for reusable PSG electrodes?

Accepted Answer

High-level disinfection or sterilization per manufacturer guidelines

Answer

Reusable electrodes that contact intact skin require at minimum high-level disinfection (or sterilization) following manufacturer guidelines and facility infection control policies.

Question 4

A patient becomes increasingly agitated and attempts to remove electrodes during a PSG. What is the FIRST action a technologist should take?

Accepted Answer

Enter the patient room, calmly reorient the patient, and assess for safety

Answer

The first action is to enter the room, reorient the patient, and assess the situation for safety—standard patient care before any intervention.

Question 5

Which documentation element is REQUIRED in the PSG technologist's report for every study?

Accepted Answer

Lights-out and lights-on times with patient-reported sleep quality

Answer

Lights-out and lights-on times establish the time-in-bed and opportunity for sleep, which are essential parameters for all PSG report documentation.
