The only thing that threw me off on sepsis was the BP....foley and ALOC (plus the previous uti) were good questions because that's what made me think about temp and skin signs.
Not everyone with SIRS/sepsis present with hypotension and/or shock. An uncomplicated infection in the elderly can easily cause AMS and weakness without unstable vitals. Also, she is likely compensated given the HR. So I wouldn't rule out sepsis from a differential just because there is no hypotension.
