RPSGT PRACTICE EXAM WITH CORRECT ANSWERS

A PATIENTS OXIMETER READING DURING PATIENT CALIBRATION IS 88%. WHICH OF THE FOLLOWING WOULD BE THE APPROPRIATE RESPONSE? -Answer- PLACE THE PROBE ON THE PATIENTS EARLOBE A PATIENT WITH ONDINES CURSE WOULD BE EXPECTED TO HAVE WHICH TYPE OF RESPIRATORY IMPAIRMENT IN SLEEP -Answer- CENTRAL SLEEP APNEA ACCORDING TO THE AASM, INTERCOSTAL EMG ACTIVITY IS AN ACCEPTABLE ALTERNATIVE SESOR FOR RECORDING WHAT PARMETER -Answer- DETECTION OF RESPIRATORY EFFORT SLOW ROLLING EYE MOVEMENTS OCCURING DURING STAGE N1 SLEEP WILL BEST BE SEEN AT LOW FILTER SETTING OF -Answer- 0.3HZ A 1.0 HZ EEG WAVE IS MEASURED AT 15MM PEAK TO PEAK. THE SENSITIVITY IS 5UV/MM. THE VOLTAGE OF THE WAVE IS -Answer- 75UV A CHEYNE STOKES BREATHING PATTERN IS OFTEN SEEN IN PATIENTS WITH -Answer- CONGESTIVE HEART FAILURE CAPNOGRAPHY MEASURES -Answer- EXPIRED CO2 WHICH OF THE FOLLOWING HIGH FREQUENCY FILTER SETTINGS IS RECOMMENDED FOR RECORDING SUBMENTAL EMG -Answer- 100HZ ENDOESOPHAGEAL PRESSURE MEASUREMENTS WOULD BE MOST HELPFUL IN EVALUTATING WHICH SLEEP DISORDERS -Answer- SLEEP RELATED BREATHING DISORDERS A PATIENT BEING EVALUATED FOR OBSTRUCTIVE SLEEP DISORDERED BREATHING HAS ATRIAL FIBRILLATION. WHAT SHOULD THE TECH DO -Answer- CONTINUE TO OBSERVE AND DOCUMENT RHYTHM WHICH OF THE FOLLOWING IS THE MOST DANGEROUS CARDIAC RHYTHM -Answer- VENTRICULAR FIBRILLATION HOW WOULD YOU COMPUTE SLEEP EFFICIENCY -Answer- TOTAL SLEEP TIME DIVIDED BY TIME IN BED X 100 HOW DO YOU CALCULATE APNEA + HYPOPNEA INDEX -Answer- # APNEAS AND HYPOPNEAS DIVIDED BY TST X60 WHICH HIGH PASS FILTER SETTING IS MOST APPROPRIATE FOR RECORDING RESPIRATION -Answer- 0.1HZ THE PURPOSE OF AN EXHALATION PORT IN A CPAP CIRCUIT IS -Answer- TO VENT EXHALED C02 WHICH OF THE FOLLOWING ARE CHARACTERISTIC OF A PVC -Answer- THE QRS IS WIDE AND BIZARRE A NORMAL VARIATION IN SINUS RHYTHM WHICH IS RELATED TO RESPIRATORY RATE AND RESULTS FROM VAGAL TONE INHIBITION DESCRIBES -Answer- SINUS ARRHYTHMIA A SUSTAINED HEART RATE OF 90 BEATS/MINUTE DESCRIBES -Answer- SINUS TACHYCARDIA PARTIAL AV BLOCK IN WHICH THE PR INTERVAL INCREASES PROGRESSIVELY UNTIL THERE IS AN ATRIAL IMPULSE WITHOUT A CORRESPONDING VENTRICULAR BEAT DESCRIBES -Answer- MOBITZ TYPE 1 AV BLOCK WHAT IS THE MOST LIKELY LOW FREQUENCY FILTER SETTING OF CHANNEL 1 -Answer- 1.0 HZ WHICH CHANNEL SETTING IS BEST FOR EMG RECORDING -Answer- 2 CHAN 2 HAS A VERY QUICH RETURN TO BASELINE, (VERY SHORT TIME CONSTAT) REFER TO THE 30 SECOND EPOCH SHOWN HERE. IF THE NEXT EPOCH CONTAINS 30 SECONDS OF LOW VOLTAGE, MIXED FREQUENCY IN THE 4-7 HZ RANGE, AND NO EYE MOVEMENTS, WHAT IS THE SLEEP STAGE OF THAT NEXT EPOCH? -Answer- STAGE N1 THE EPOCH SHOWN CONTAINS A K COMPLEX, POSSIBLE A SPINDLE AND LESS THAN 20% HIGH AMPLITUDE SLOW WAVES, MAKING IT STAGE N2 THERE IS AN AROUSAL AT THE END OF THE EPOCH. IF THE FOLLOWING EPOCH IS AS DESCRIVED, WITHOUT EITHER A K COMPLEX OR SPINDLE. IT IS THEN STAGE N1 A PATIENT HAS POOR EXTREMITY CIRCULATION THAT IS AFFECTING THE ACCURACY OF THE PULSE OXIMETRY READINGS FROM FINGER PROBE. WHICH WOULD BE THE MOST APPROPRIATE ACTION -Answer- PUT THE PROBE ON THE PATIENTS EAR SCORING STAGE N1 SLEEP REQUIRES AN ABSENCE OF -Answer- SLEEP SPINDLES CARDIAC ACTIVITY IN WHICH ALL ATRIAL IMPULSES ARE BLOCKED AT THE AV JUNCTION, AND THE ATRIA AND VENTRICLES BEAT INDEPENDENTLY IS CALLED -Answer- 3RD DEGREE AV BLOCK WHICH OF THE FOLLOWING IS AN EXAMPLE OF A RHYTHMIC MOVEMENT DISORDER -Answer- JACTATIO CAPITIS NOCTURNA SLEEP TERRORS ARE USUALLY ASSOCIATED WITH -Answer- OCCURRENCE IN THE 1ST THIRD OF THE SLEEP PERIOD THE IMAGE SHOWN HERE IS AN EXAMPLE OF -Answer- BRUXISM THE IMAGE SHOWN HERE, IS AN EXAMPLE OF -Answer- WENCHEBACH AV BLOCK IN THE IMAGE SHOWN HERE, LOCATION 6 CORRESPONDS TO WHICH ELECTRODE -Answer- F4 THE IMAGE SHOWN HERE, IS AN EXAMPLE OF -Answer- ATRIAL FLUTTER WHAT IS THE CARDIAC ACTIVITY IN THE IMAGE SHOWN HERE -Answer- COUPLET ACCORDING TO THE 10-20 INTERNATIONAL SYSTEM OF ELECTRODE PLACEMENT, T3 IS LOCATED -Answer- 10% ABOVE THE LEFT PREAURICULAR POINT ACCORDING TO THE 10-20 INTERNATIONAL SYSTEM OF ELECTRODE PLACEMENT, CZ IS LOCATED -Answer- AT THE MIDPOINT BETWEEN THE 2 PREAURICULAR POINTS AND THE NASION AND INION THE ANTERIOR-POSTERIOR INTERSECTION FOR THE PLACEMENT OF C3 IS LOCATED BY MEASURING -Answer- 50% OF THE DISTANCE BETWEEN FP1 AND O1 USING THE
