Which of the following gas concentrations should be used
to set the slope control when calibrating the PCO2
electrode of a blood gas analyzer?
A. 5%
B. 10%

The PFT performs a single breath CO diffusion capacity test on a 54 year old pt diagnosed with COPD. The tech connects a sample line to the infrared absorption anaalyzer. This could result in A. faster absorption of the gases B. Failure of the chopper motor C. An increase in the response time D. Improper calibration - correct answers D. The PFT performs an FRC measurement on a 62 year old pt. During testing, the pt complains that she can inhale but it is very hard to exhale. THe tech should suspect A. excessive O2 flow in the circuit B. Incorrect position of the exhalation valve C. Exhausted scrubber D. Failure of the chopper motor - correct answers B. The PFT administers methacholine via breath actuated nebulizer to a pt as part of a bronchial provocation study. During the treatment the pt is having difficulty with nebulization of the drug. The most likely explanation is that A. the pt is unable to generate enough flow through the nebulizer B. the exhalation valve is obstructed C. the connecting tubing is too long

A. moisture accumlation in the transducer lines B. Cooling of the pneumotachometer C. Inaccurate current flow used during testing D. increased resistance in the system - correct answers A The PFT utilizes a theremal element to measure flow rates during a pulmonary function study. THe tech notes that the volume readings are uncharacterisctically low in comparision to the pts previous PFT. This could be caused by A. Increased compliance B. High amount of deadspace C. decreased resistance D. Low temperature - correct answers C. At the end of the day, the PFT reviews the lists of pts scheduled for testing for the following day. The tech notes that there is a pt who is suspected of having TB scheduled for mid morning testing. THe tech should A. Contact the referring MD B. cancel the appt C. proceed at the scheduled time D. reshedule the pt for the end of the day - correct answers D.

THe PFT performs an exercise test on a 42 year old pt. The tech applied the ECG electrodes and notes that the tracing produces a large amount of artifact. In order to eliminate the artifact the tech should A. place the electrodes directly over bony areas B. replace the electrodes C. assure that the skin was properly prepared D. adjust the gain control on the monitor - correct answers C. THe PFT performs an FRC measurement utilizing a body box. During the procedure the pt continues to complain that it is very hot inside the box. To reduce the temp inside the box, the tech should A. perform a calibration test B. close the vent to the box C. Open the door to the box D. Increase the gain - correct answers C. THe PFT performs daily calibration of the pH electrode in the blood gas analyzer. The is using a 6.840 solution for the new low value and a 7.384 solution for the high value. The machine display for the low value does not match the calibraiton values. The tech should A. adjust the balance control until the display matches the pH of the solution
