I’m a bit confused about the percentages. Does D5 mean there’s 5 grams of dextrose per 100ml? I hope I remember that right!

I feel like I might be overthinking this. Is it just the concentration times the total volume over 24 hours?

I think we practiced a similar question in class, and I recall that we need to find the total volume first before calculating the dextrose amount.

I remember something about calculating dextrose in IV fluids, but I'm not sure how to break it down for this specific question.
