Tapenja Lott is a 44 year old lighting consultant with no history of lung disease. Over the last several days she has experienced increasing dyspnea, malaise and productive cough. She presented to the emergency department with the following VS: HR 136 bpm, B/P 138/84, RR 26 bpm which are shallow with mild to moderate accessory muscle use, temp 39.8 C. Breath sounds reveal bilateral inspiratory and expiratory crackles, CXR reveals large areas of RLL and RML consolidation. She has been diagnosed with pneumonia. ABGs are drawn on an FiO2 of 0.28:pH         7.51PaCO2  28 torrPaO2    43 torrHCO3   20 mEq/LSaO2    68%Which of the following best describes her arterial blood gas?
