The critical care nurse is caring for a patient with a pulmonary artery pressure monitoring system
The nurse is aware that pulmonary artery pressure monitoring is used to assess left ventricular function (cardiac output.) What else are pulmonary artery pressure monitoring systems used for?
A) To assess the patient's response to interventions such as fluid administration and drug administration
B) To obtain specimens for arterial blood gas measurements
C) They have been determined to not be clinically useful for continuous monitoring of a patient with heart failure
D) To diagnose the etiology of chronic obstructive pulmonary disease
Ans: A
Feedback: Pulmonary artery pressure monitoring is an important tool used in critical care for assessing left ventricular function (cardiac output), diagnosing the etiology of shock, and evaluating the patient's response to medical interventions such as fluid administration and response to vasoactive medications. Pulmonary artery monitoring is preferred for the patient with heart failure over central venous pressure monitoring. Arterial catheters are useful when arterial blood gas measurements and blood samples need to be obtained frequently.
