CRT/RRT practice questions and answers 2024

Vesicular breath sounds are auscultated with which of the following - 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. - 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. - 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. - 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 - Right leg The most commonly occurring complication of airway suctioning is which of the following - 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 - 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 - Linearity Application of suction during withdrawal of a suction catheter should not exceed a maximum of - 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
