Infections and Veins

The IV nurse is trying to find a good vein on Sarah's foot to get an IV hooked up so they can get Sarah some blood. Her proteins are down and they want avoid giving her more liquid that could put fluid in her stomach. She has an infection of some kind but it hasn't been narrowed down yet. All we know at this point is the CRP, an indicator, is high and some white cell counts are looking strange which points to an infection. Plus, she is still having this on again, off again rash all over her body that we can't nail down the cause for.
