BRPT Study Guide Sample Questions Graded A

A patient is referred for sleep testing for evaluation of suspected idiopathic hypersomnia of central nervous system origin. This sleep disorder is characterized by - Excessive daytime sleepiness without REM onset sleep. Origin of narcolepsy. - central nervous system. Device used to monitor respiratory airflow. - Thermocouple. Measurement for SpO2. - Pulse oximeter. Records ECG. - Modified Lead II. Records respiratory effort. - Piezo-electric band. The tech enters a bedroom before the patient arrives and finds the bed linens are crumpled and there is a stain on one of the pillow cases. The technologist should - Change the bed linens in case someone used the bed during the day. While preparing for physiological calibrations, the video image on the recording system is noted to be blank. What is the technologist's best course of action. - Verify the camera is on and the lens cover is off. A patient is referred for evaluation of intermittent lip smacking, groaning, and incontinence during sleep. The technologist should consider using a montage with. - Expanded EEG electrode derivations. Lip smacking, groaning, and incontinence are symptoms of what. - Seizure. When evaluating the patient chart, the technologist should verify - the test order is complete and signed. The patient's sleep study order indicates a follow up sleep study with the PAP titration. There is no evidence of a previous sleep study in the patient's history, and the patient denies having a previous sleep test. The technologist should - Contact the physician for discussion and order clarification. Scalp electrodes used to record sleep stages are typically referenced to the - mastoid process. The distance between Fp1 and O1 is 25cm. What is the distance in cm between F3 and C3? What is the percentage. - 6.25cm 25% Sleep history reveals abrupt awakenings during the second half of the night, associated with terrifying dreams and difficulty returning to sleep. The technologist should anticipate the occurrence of - nightmares. Occurs earlier in the night, and is associated with slow wave sleep with little to no recall of dreams. - Night terror disorder. When do hypnagogic hallucinations occur? - Sleep onset. Input voltage of a calibration signal is 50 microvolts and the output deflection measures 5 mm on the display screen. What is the sensitivity in microvolts/mm? - 10 How is sensitivity usually expressed? - microvolts/mm or millivolts/cm How is sensitivity calculated? - Divide input voltage by signal deflection. Recommended low frequency filter for the EMG. - 10Hz How would too much high frequency filtering affect the calibration signal? - Cause a rounded tip. Before bedtime, the patient informs the tech that a dose of prescription antibiotic meds is needed around 2am. The patient has the medication but needs help waking up at the appointed time. The tech responds by - wake the patient at 2am, document the medication, dosage, and time.
