What information do you want to know?
You assess the patient and think that they are dehydrated. They are mildly tachycardic, but with a maintained BP and otherwise the obs are normal. This mornings results have just come back and they show this:
U 14.2 (previously normal)
FBC normal, CRP 95
Write out a fluid chart for the patient for the next 24 hours, taking in to account the results that you have to date. For the sake of simplicity assume that there will be a further 500 ml drained from the NG tube which has just been passed
Patient number 12345678
In order to get some prescribing resources out there we intend to publish a series of prescribing problems on the website. The problems will appear at least weekly with the "answers" appearing a couple of days later. We'll use the standard exam stationery available on the LSE, but also available below in case you haven't got access to the LSE.
