I thought it was 90mg, but I guess not.

It's 25.92gm, right? Simple math!

I feel like I might be overthinking this. Is it just a matter of multiplying the flow rate by the concentration?

If NS is 0.9%, that means there are 9 grams of sodium chloride in 1 liter, right? So I need to figure out how much that is in 24 hours.

I think we did a similar question in practice about IV fluids, but I can't recall the exact steps for this one.

I remember we calculated the total volume first, but I'm not sure how to convert that to grams of sodium chloride.

This seems straightforward enough. I'll just need to convert the volume to liters, multiply by the concentration, and that should give me the total grams of sodium chloride. I'm feeling pretty confident about this one.

Okay, I think I've got this. If the patient is getting 120mL/hr, that's 2,880mL in 24 hours (120mL x 24 hours). Since NS is 0.9% sodium chloride, that means there are 9 grams of sodium chloride per liter. So the total amount of sodium chloride is 2.592 grams (2,880mL / 1000mL/L x 0.9g/L).

I'm a little confused on how to approach this. Do I need to convert the volume to milliliters first, or can I just work in liters? And what formula should I use to calculate the total grams?

Hmm, this seems straightforward, but I want to make sure I have the right approach. I'll need to convert the volume to liters, then multiply by the concentration to get the total amount of sodium chloride.

Okay, let's think this through step-by-step. We know the patient is getting NS IVF at 120mL/hr, and NS is 0.9% sodium chloride. We need to calculate the total amount of sodium chloride in grams over 24 hours.

90mg? Really? That seems way too low for a 24-hour IV infusion. I'm sticking with A) on this one.
