How would oral medication be given to patient in ICU that can't swallow? I was told that the tablets are grind and put in water then provided through a tube. Is this true? How would the nurse know the effect of interaction resulting from mixing those ground pills? Thanks.
After some research I found this topic which answers part of my question. It does not answer the chemical effects of mixing drugs outside the human body.

I find the process of grinding different pills and serving them altogether strange I am almost sure that this can't be generally correct.
