I really would like someone to EXPLAIN to me, or guide to a resource. Seem to have some confusion as to why a solution is given to a patient. When I ask my preceptor(just started on a med/surg unit), she says "I don't know, different doctors prescribe different solutions, so I don't know why they did it". And that we're not about to page the Dr to ask him/her why the pt is having the solution!!!
Well, aren't we suppose to know why a solution is prescribed and what it does in the body in relation to fluid shifts, electrolytes and cautions?!
I tried to find answers online, but google just lists basic iso/hypo/hyper solutions with no explanations?
