Septic shock and pneumonia?

*** (Doctor Question) *** My mom came into ICU from a bad combo of medications Klonopin and some kind of muscle relaxer that dropped her breathing almost to nothing. She aspirated into her lungs in the er which gave her pneumonia. This is day 5. Day 3 they took her off ventilator and she was pretty restless, high heart rate, small and shorts breaths and complained of chest pains in which they did a ct scan and found some clots in her legs and one in lung. They put her on thinners injected into her abdomen (Something starting with a L)and placed a screen in a main vein in her abdomen to catch any clots that get loose. They placed her back on ventilator for a few days. This being day 5 they think she went into septic shock. They started her antibiotics on day 1 after the aspiration. They said her elevated white blood cell count did go down from yesterday. She has low blood pressure, increased heart rate and such. Her being 62 and the chain of events taking place....how does it look? What questions would be good to ask doctors to see if they are missing anything important?
