[COLOR=#000000] [/COLOR][COLOR=#000000]My nsg diagnosis would be Fluid volume deficit r/t nausea and diarrhea[/COLOR]

[COLOR=#000000] [/COLOR][COLOR=#000000] [/COLOR]

[COLOR=#000000] [/COLOR][COLOR=#000000]I would[/COLOR] monitor intake and output, and assess vital signs, and monitor for signs / symptoms of dehydration.

[COLOR=#000000]I need to figure out what factors contributed to his altered vital signs and abnormal lab values, (not sure why creatinine is so low) and what type of IV therapy might be used to restore this patient's fluid and electrolyte balance, I want to say Normal saline, but I feel like that is not enough and I am not sure the difference between Isotonic, hypo/hypertonic solutions.[/COLOR]

[COLOR=#000000] [/COLOR][COLOR=#000000] [/COLOR]

[COLOR=#000000] [/COLOR][COLOR=#000000]Can someone help me please?[/COLOR]

You may have better luck getting responses if you ask the mods to edit your thread if you are no longer able to or reposting your question without copying and pasting since it seems to cause a lot of font/color tags that make the post unreadable. I had to give up after the first few lines.
