Oh, I see! So maybe D) 150gm is correct then.

Right! So, 5% of 3000ml is 150gm of dextrose.

But wait, 125ml/hour for 24 hours is 3000ml total.

I feel like it's A) 300gm. 5% dextrose in 125ml is significant.

Yeah, I agree. 125ml/hour for 24 hours means a lot of fluid.

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.
