I have to recommend this post by spacefan, discussing some similar gripes.
I think patients have to get over the fact that an IV line will NOT solve dyspnea, cough, fever, headache, and chest pain.
I'd love for someone to invent a single IV solution that will never congest patients, never clog up sites, and never elicit complaints from patients ever again. But that's just wishful thinking.
Also, this open letter by aliendoc is brilliant. Simply brilliant.
