Answer to Question 1

ANS: C
Indications for pulmonary artery monitoring include preexisting cardiac or pulmonary disease in a patient undergoing a major vascular, intraabdominal, or neurosurgical procedure, and a potential risk of development of cardiopulmonary instability from the stress of the surgical procedure. Other conditions may include shock, burns with large fluid shifts, renal failure with low CO, or pulmonary emboli. Pulmonary artery catheters may be used in patients who require long-term monitoring.

Answer to Question 2

ANS: C
When the catheter floats through the pulmonary semilunar valve into the pulmonary artery, a pulmonary artery tracing should appear on the monitor. This waveform has a steep upstroke at the beginning from right ventricular ejection and opening of the pulmonic valve, followed by a dicrotic notch on the downstroke at the closing of the pulmonic valve.
