I think the answer is around 4.0 mL/hr, but I’m not confident. I wish I had reviewed the calculations more thoroughly before the exam.

I feel like I might be overthinking this. If I recall correctly, we need to convert the 0.03 units/min to an hourly rate first, right?

This seems similar to that practice question we did on heparin drips. I think I need to remember the concentration to get the right mL/hr.

I remember we practiced calculating infusion rates, but I'm not entirely sure how to convert the units for vasopressin.

Okay, let me think this through. I need to find the rate in mL/hr that will deliver 0.03 units/min of vasopressin. I'll start by converting the units and then do the math.

I've got this! First, I'll convert the 0.03 units/min to units/hr. Then I'll use the standard mix to calculate the mL/hr. Easy peasy.

Okay, let's think this through step-by-step. We have 0.03 units/min of vasopressin, and the standard mix is 40 units in 100ml NS. We need to find the rate in mL/hr.

I believe the correct answer is A) 4.0 ml/hr. The calculation is correct, and it makes sense to me. So, I will go with A) 4.0 ml/hr.

D) 3.5ml/hr? Really? I think the person who came up with that option must have been sleeping during the lecture on vasopressin dosing.

I agree with Lelia, because 0.03 units/min x 60 min/hr = 1.8 units/hr. And 1.8 units/hr / 40 units/100ml = 0.045 ml/hr. So, the answer is A) 4.0 ml/hr.

I think the correct answer is B) 4.9ml/hr. The question gives the rate of vasopressin needed as 0.03 units/min, and the standard mix is 40 units in 100ml. So, we need to calculate the rate in ml/hr to deliver 0.03 units/min.
