COMPLETE 650 REAL EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
ALREADY GRADED A+ (BRAND NEW!!)
1. Before initiating a polysomnography (PSG) study, what is
the FIRST action a sleep technologist must take?
A) Prepare the equipment and check for proper calibration
B) Interview the patient and review medical history
C) Review the physician's order to confirm the test type
D) Set the room temperature to a comfortable level
Correct Answer: C
Rationale: The physician's order is a legal and clinical
requirement that specifies the type of sleep study to be
performed (diagnostic PSG, CPAP titration, split-night study, or
MSLT). Performing the wrong test is a serious error that can
delay diagnosis, waste resources, and compromise patient care .
The order must be verified before any other setup activities
begin.

,2. Which questionnaire is the standard tool used to quantify a
patient's level of daytime sleepiness?
A) STOP-BANG Questionnaire
B) Berlin Questionnaire
C) Epworth Sleepiness Scale (ESS)
D) Pittsburgh Sleep Quality Index (PSQI)
Correct Answer: C
Rationale: The Epworth Sleepiness Scale asks patients to rate
their likelihood of dozing off in eight common daily situations. It is
the most widely used tool for assessing subjective daytime
sleepiness and helps determine the need for further testing such
as MSLT .
3. A patient reports an Epworth Sleepiness Scale score of 18.
What clinical inference can the technologist make?
A) The patient has normal daytime alertness
B) The patient has mild excessive daytime sleepiness
C) The patient has severe excessive daytime sleepiness
D) The score is invalid and must be readministered
Correct Answer: C
Rationale: Normal ESS scores typically range from 0-10. Scores
2
,of 11-15 indicate mild to moderate excessive daytime
sleepiness, while scores above 16 indicate severe excessive
daytime sleepiness. A score of 18 warrants further objective
testing such as MSLT .
4. What is the purpose of reviewing the patient's medication
list before a sleep study?
A) To verify the patient's insurance coverage for medications
B) To identify medications that may suppress REM sleep or affect
sleep architecture
C) To ensure the patient takes all medications as scheduled
during the study
D) To bill the patient's pharmacy benefit for the study
Correct Answer: B
Rationale: Many medications affect sleep architecture. SSRIs
(e.g., fluoxetine, sertraline) suppress REM sleep, prolong REM
latency, and reduce REM percentage. Benzodiazepines increase
N2 sleep and decrease N3/REM. Stimulants delay sleep onset.
Knowing the medication list helps the technologist interpret
atypical findings and communicate with the ordering physician .
3
, 5. According to the Patient's Bill of Rights, patient medical
records should only be accessed by:
A) Any staff member working in the laboratory
B) Only the patient and their immediate family
C) Individuals who need the information for procedures,
diagnosis, or treatment
D) All employees of the healthcare system regardless of role
Correct Answer: C
Rationale: Patient confidentiality is a legal and ethical
requirement. Medical records may only be accessed by those
directly involved in the patient's care. Unauthorized access
violates HIPAA regulations and the Patient's Bill of Rights .
6. The legal doctrine "Respondeat Superior" means:
A) The patient is ultimately responsible for their own care
outcomes
B) The thing speaks for itself (negligence is assumed)
C) Employers are held liable for the actions of their employees
during work
D) First, do no harm (physician's primary obligation)
