### Please explain medical term "clinical reaction". Online reference would be nice.?

Our doctor used the term "clinical reaction", but did not provide a clear explanation. A web search shows this is a very common term, but I cannot find a definition, even in the online medical terminology dictionaries. Can anyone provide a concise explanation of the term and possibly provide the URL of a site supporting this definition? Thanks!

Can you please help with steps to solve Z^4 + Z^2 = 1/4? Answer: Z=+/- 0.455, but how is it solved? I'm drawing a blank. No, this is not a homework problem, but rather self-study. Thanks!
