question: Q:An 83-year-old woman with a past medical history of poorly controlled diabetes, hyperlipidemia, hypertension, obesity, and recurrent urinary tract infections is brought to the emergency room by her husband due to confusion, generalized malaise and weakness, nausea, and mild lower abdominal pain. Her medications include metformin and glyburide, atorvastatin, lisinopril, and hydrochlorothiazide. At presentation, her oral temperature is 38.9°C (102.2°F), the pulse is 122/min, blood pressure is 93/40 mm Hg, and oxygen saturation is 96% on room air. On physical examination, she is breathing rapid shallow breaths but does not have any rales or crackles on pulmonary auscultation. No murmurs are heard on cardiac auscultation and femoral pulses are bounding. Her skin is warm, flushed, and dry to touch. There is trace bilateral pedal edema present. Her abdomen is soft and non-distended, but she has some involuntary guarding on palpation of the suprapubic region. ECG shows normal amplitude sinus tachycardia without evidence of ST-segment changes or T-wave inversions. Which of the following would most likely be the relative pulmonary artery catheterization measurements of pulmonary capillary wedge pressure (PCWP), mixed venous oxygen saturation (SaO2), calculated cardiac output (CO), and systemic vascular resistance (SVR) in this patient?? 
  {'A': 'Decreased PCWP; normal SaO2; decreased CO; and decreased SVR', 'B': 'Decreased PCWP; decreased SaO2; decreased CO; increased SVR', 'C': 'Normal PCWP; normal SaO2; increased CO; decreased SVR', 'D': 'Decreased PCWP; slightly increased SaO2; increased CO; decreased SVR', 'E': 'Increased PCWP; decreased SaO2; decreased CO; increased SVR'},
