Vesicular breath sounds are auscultated with which of the following - Answer Normal lungs Transcutaneous monitoring (TMC) is being used with a newborn in the NICU. The temperature at the sensor site is 37 deg C. Concurrent arterial blood gases indicate significantly higher values for oxygen tension that those obtained by TMC to correct the problem therapist should First. - Answer Heat sensor site to a temperature of 44 deg C While doing an exercise on the treadmill. A candidate undergoing stress testing for cardiopulmonary rehabilitation suddenly develops premature ventricular contractions on the ECG tracing. The respiratory therapist monitoring the procedure should recommend which of the following. - Answer Terminating the stress test A patient has been diagnosed with vocal cord polyps. Which of the following pulmonary function test would best evaluate the degree of impairment. - Answer MEFV (Maximal Expiratory Flow- Volume) While performing an ECG the monitor suddenly shows a flat line pattern for all leads. Which of the following electrodes should be prepped or re-attached - Answer Right leg The most commonly occurring complication of airway suctioning is which of the following - Answer Mucosal trauma Monitors for a patient in the intensive care unit indicate a heart rate of 102/min, RR of 22/min, BP of 134/86. Laboratory test shows a serum glucose of 210 mEq/L and BUN of 12 mg/dL. Arterial blood gas results are as follows: pH 7.26, PaCO2 27,
PaO3 94 HCO3- 12 mEq/L. Based on this data the most appropriate clinical response would be which of the following - Answer Administration of insulin Quality control procedures are completed on a flow measuring device. Observed data shows variations from actual for the middle range of test measurements. These results suggest a problem with - Answer Linearity Application of suction during withdrawal of a suction catheter should not exceed a maximum of - Answer 15 sec The high pressure alarm is sounding with each breath of a patient being mechanically ventilated in the ICU. The patients oxygen saturation level via pulse oximetry is quickly falling and the cardiac monitor shows hypotension and tachycardia. Further assessment by the RT reveals marked tracheal deviation to the right and breath sounds are absent on the left. Rapid confirmation of this patients diagnosis is most appropriately obtained by - Answer Left anterior - apical catheter insertion A patient admitted to the ER with no inspiratory effects has been incubated and placed on mechanical ventilation would be which of the following - Answer A/C An arterial sample of blood is obtained from a patient on room air for blood gas analysis. Air bubbles mixed with the sample would cause what errors to occur (pH, PaCO2, PaO2) with the analysis results - Answer Increased pH, decreased PaCO2, increased PaO Accuracy of recording devices used in the PFT may be checked with which of the following - Answer Stopwatch
A high frequency jet ventilator system incorporates which of the following controls? Oscillatory pressure amplitude Bias flow Mean airway pressure Drive pressure regulator - Answer Drive pressure regulator A large volume neb is being used to provide continuous aerosol for a patient via t piece. The RT on duty is unable to discern a steady mist at the t-piece reservoir tube. This problem may be the result of which of the following Flow rate exceeds patient demands Condensation in aerosol tubing Non pressure compensated Thorpe tube Patient lethargy - Answer Condensation in aerosol tubing A premature female had been born by C section and placed on an infant warmer. The baby is breathing spontaneously, her airway had been cleared, and the infants heart rate is 80 bpm. The RT assisting with the care of the infant should of do which of the following Provide free flow oxygen Evaluate color Being chest compressions Apply PPV - Answer Apply PPV
