Question 8

Which of the following include the most appropriate insertion site(s)for a pulmonary catheter in a patient with phlebitis?
1)Internal jugular vein
2)Subclavian vein
3)Antecubital vein
4)Femoral vein

Accepted Answer

The reason the antecubital and femoral veins are not appropriate for the insertion for this patient is because one of the common problems associated with these sites is phlebitis.Using either of these sites in a patient who already has phlebitis would put the patient at risk for worsening the patient's condition.

Question 9

Question 15

Which of the following can occur with excessive pulmonary artery catheter movement?

Accepted Answer

Excessive catheter movement can cause catheter knotting.Catheter whip is caused by high cardiac output or abnormal vessel diameter.Balloon rupture is due to loss of balloon elasticity or overinflation.Dampening of the waveform can be caused by air in line,a clot in the system,kinks in line,a catheter tip against the vessel wall,over-wedging,or blood on the transducer.

Question 20

The waveform of a pulmonary catheter,shown in the figure,is located in which of the following?

Accepted Answer

The figure shows a systolic pressure of approximately 22 mm Hg and a diastolic of approximately 8-10 mm Hg.This falls within the normal pulmonary artery pressures of 15-35/5-15 mm Hg.The presence of the dicrotic notch is another hint that the catheter is in the pulmonary artery.The right atrial pressure is normally between 2 and 6 mm Hg.A catheter in the right ventricle would show pressures of 15-35/2-6 mm Hg.The pulmonary capillary wedge pressure (PCWP or PAOP)normally varies between 2 and 15 mm Hg.
