A 22-year-old woman reports being "sick with the flu" for the past 8 days. She is vomiting several times every day, having difficulty keeping liquids or food down, and has been using more than the recommended dose of antacids in an attempt to calm the nausea. She has become severely dehydrated. After fainting at home, she was taken to a local hospital. An arterial blood gas sample was drawn and then an IV was placed to help rehydrate her. The arterial blood gas revealed the following:
