Rounding units of insulin

[RNSAINT41]

Here is an example question. A type 2 diabetic is prescribed lantus 0.2units/kg qd and the patient weighs 197 pounds how many units of insulin should the patient receive? The answer I come up with is 17.9 units using DA but is this amount rounded up to 18 units or down to 17 units?

If this is a problem for school, you need to follow whatever rounding rules your instructor specified for the class. In practice, I would round to 18 units per standard rounding rules, up to the suggested maximum dose.
