Question 1 of 10
1. Question
When measuring thermodilution cardiac output in a patient, you notice that the values are higher than expected. What action can you take when troubleshooting the problem?
Correct
When thermodilution cardiac output measurements are higher than expected one can reposition the catheter, advance the catheter, pull the catheter back, carefully remove air bubbles from the syringe, from the distal lumen verify PA waveform.

Question 6 of 10
6. Question
During pulmonary artery pressure measurement, you notice a fling/noise in the pressure waveform. How can you treat rectify this problem?
Correct
To treat a noise/fling in pressure during pulmonary artery pressure measurement one can try different catheter positions, or try eliminating excess tubing, or try eliminating excess stopcocks.

7. Question
Which of the following is not a cause of irregular upslope associated with thermodilution cardiac output measurements?
Correct
An irregular upslope of the CO curve can be caused by magnetic interference, the long lag time between injection and upstroke of the curve, partially occluded RA port, partially kinked catheter, and uneven injection technique.
