  A previously healthy 21-year-old woman comes to the local college clinic because of a headache and low-grade fevers. She is sent home with acetaminophen and advised to return if she does not improve. Approximately three hours later her roommate calls 911 reporting that her friend is unconscious and not arousable. On arrival the paramedics find a lethargic, febrile female lying on the floor and unresponsive. The patient is stabilized and she is rushed emergently to the local hospital where an abdominal CT scan shows bilateral adrenal hemorrhages. The patient is transported to the intensive care unit where a pulmonary artery catheter is inserted via a right internal jugular vein. Her temperature is 39.3 C (102.8 F), blood pressure is 85/40 mm Hg, and pulse is 140/min. An electrocardiogram demonstrates sinus tachycardia. Her extremities are warm to the touch and appear pink. A cardiac output (CO), systemic vascular resistance (SVR), pulmonary capillary wedge pressure (PCWP) and central venous pressure (CVP) are obtained. The data acquired from her PA-line is most likely to be

A. CO 5.0 L/min, SVR 800 dynes-sec/cm5, PCWP 12 mm Hg, CVP 4 mm Hg

B. CO 9.5 L/min, SVR 210 dynes-sec/cm5, PCWP 8 mm Hg, CVP 6 mm Hg

C. CO 2.3 L/min, SVR 1500 dynes-sec/cm5, PCWP 30 mm Hg, CVP 10 mm Hg

D. CO 3.0 L/min, SVR 1500 dynes-sec/cm5, PCWP 8 mm Hg, CVP 1 mm Hg

E. CO 9.5 L/min, SVR 1210 dynes-sec/cm5, PCWP 12 mm Hg, CVP 6 mm
