A. Spinal cord perfusion is not monitored with a pulmonary artery catheter; it typically requires different neuromonitoring techniques. B. Hemodynamic status is accurately monitored using a pulmonary artery catheter (also called a Swan-Ganz catheter), which provides information on cardiac output, pulmonary artery pressures, and other cardiovascular parameters. C. Intracranial pressure is monitored using devices like an intraventricular catheter or subarachnoid bolt, not a pulmonary artery catheter. D. Renal function is assessed through laboratory tests (e.g., BUN, creatinine) and urine output, not via a pulmonary artery catheter
