50 mcg/kg/min 80 kg = 4 mg/min 60 min/hr = 240 mg/hr 2500 mg / 250 mL = 10 mg/mL 240 mg/hr / 10 mg/ mL = 24 mL/hr Esmolol Infusion

Just double-checking, but isn't Esmolol super short-acting?

I disagree, I got 24mls/hr after my calculations.

Wait, how do you even calculate that? Seems tricky!

I think the answer is 32mls/hr, right?

The dose is 50mcg/kg/min for 80kg, so that's 4000mcg/min.

I feel like the answer is around 20mls/hr, but I can't recall how I got there. I need to double-check my calculations.

I’m a bit confused about the conversion from mcg to mg. Was it 1000 mcg in a mg? I hope I remember that right.

I think we need to convert the mcg/kg/min to mg/min first, then figure out the total volume. It feels similar to that practice question we did last week.

I remember we calculated infusion rates in pharmacology, but I'm not sure about the exact steps for this one.

Hmm, this seems like a tricky one. I'll need to carefully consider the implications of the iterative life-cycle model and the available requirements information.

This seems like a tricky question. I'll need to think through the different Knowledge Module options carefully.
