Calculating for parenteral nutrition

If a 60 kg patient on ITU requires 1.3 g/kg/day of protein equivalents from the bag of standard PN, what hourly infusion rate should they receive?

If this patient was at a severe deficit of potassium and required a total daily dose of 120 mmol of potassium, at what rate should you run a parallel infusion of 0.3% potassium chloride in 0.9% sodium chloride with the PN to meet their potassium requirements? 0.3% potassium chloride is equivalent to 40 mmol/litre.

In catering for the patient’s potassium requirements, what will be the total amount of sodium you administer to the patient in mmol/kg/day (0.9% sodium chloride contains 154 mmol/litre)?
