Question 1 of 10
1. Question
The decrease in pulse distal to the puncture site is one of the problems associated with Arterial Catheters. Which of the following could cause this problem?
Correct
Decreased pulse distal to puncture site can be caused by spasm artery or thrombosis of the artery. The other options cannot cause a decrease in pulse distal to puncture site.
Incorrect
Decreased pulse distal to puncture site can be caused by spasm artery or thrombosis of the artery. The other options cannot cause a decrease in pulse distal to puncture site.

4. Question
The distal tip port performs various functions in relation to the pulmonary artery, which of the following is a function of the distal tip port?
Correct
The distal tip port is responsible for pressure measurement at the tip of the catheter in the Pulmonary Artery(PA). It is used to sample SvO2 levels.It can also be used to measure the pulmonary capillary wedge pressure.

5. Question
Which of the following statements is true about the balloon inflation port in relation to the Pulmonary Artery port functions?
Correct
The balloon inflation port is periodically inflated with <1.5 mL of air to obtain pulmonary capillary wedge pressure. The ventricular port is used to measure the right ventricle pressure. Proximal lumen port is used for drug and IV fluid administration, if necessary.

6. Question
Damping concepts can be accessed from a Square wave test. Which of the following best describes an optimally damped system?
Correct
In an optimally damped system , a sharp upstroke terminates in a flat line at the maximal indicator on the monitor whenever the fast flush of the continuous flush system is activated and quickly released.

Question 9 of 10
9. Question
Which of the following activities is not associated with pulmonary artery pressure measurement?
Correct
Some of the activities associated with pulmonary artery pressure measurement include verifying the accuracy of the transducer-patient interface, Positioning the patient supine prior to PAP/RAP (CVP)/PCWP measurements, using a simultaneous ECG tracing to help with proper PAP/RAP/PCWP waveform identification, and using a graphic(analog) tracing to get PAP/RAP/PCWP measurements at end-expiration.

10. Question
Phlebitis is a problem encountered with pulmonary artery catheters. Which of the following can cause phlebitis?
Correct
Phlebitis or local infection at insertion can be caused by mechanical irritation or contamination. Looping of excess catheter in RA and the migration of catheter from PA to RV can cause ventricular irritability. Distal migration of catheter tip will cause pulmonary hemorrhage or infarction.
