A pulmonary artery (PA) catheter is used in critical care patients who 1. cannot

A pulmonary artery (PA) catheter is used in critical care patients who
1. cannot tolerate hemodynamic monitoring.
2. requires a peripheral intravenous catheter for medication administration.
3. would benefit from having the right ventricle pressures measured each shift.
4. requires evaluation of left ventricular pressures each shift.

4. requires evaluation of left ventricular pressures each shift.

It is the only option that describes the use/overview of the catheter. They are indeed used to check the pulmonary pressure of the left ventricle.

1 is false, it can be used. 2 is also false because you have to know the use of a peripheral IV (it is inserted in the vein of the arms), this type is not used at all. Its proper placement is in the jugular or subclavicular vein (central IV). Think peripheries = extremities, the arm and central of course as the middle = your neck to chest. 3 is false as well, 4 already right

Pulmonary artery (PA) catheters can be used to evaluate pulmonary artery pressures, left ventricular pressures, measure cardiac output, and manipulate fluid volume status in acutely ill patients. PA catheters are a form of hemodynamic monitoring. The PA catheter does not measure right ventricular pressures and would not be used to administer medications since it is a central arterial catheter, not a peripheral line.
