Help with math problem

Thank You very much for responding. No wonder I was stuck, I did not even think to multiply by 60 min "duh". You made it seem so simple. Thanks again.

Two Questions for you Hygiene Queen.

If the problem is asking to calculate the infusion drip rate cc/hr and mentions the patient weight in lbs in the problem. Does the weight have to be included in setting up the problem to solve it.

Secondly, If the question is asking for the mg/min and includes the weight in kg, does the the weight have to be included in setting up the problem to solve it.

I guess I am confused because some questions will ask for all three such find the mg/kg/min and others will ask for just mg/min or cc/hr but may or may not include the pt weight in the question. Not sure if that is a distraction or not. I now know how to solve the problem but just not sure if I am to include the weight in solving the problem unless it specifically ask for it such solve for mcg/kg/min, etc. I hope this is clear and can receive some feedback.

Disregard, I figured it out.

The IV flow rate is volume/time, unless it's asking for drips per minute. In that case, you would use the drop factor. If it's asking for volume only, then you have to use a little algebra. The same goes for time, etc. Hope this helps. I don't want to confuse you more.

The only time that a patient's weight matters is if the dose is based on their weight (such as mcg/kg/min or mg/kg/day, etc)

So if the question reads like: A patient is receiving epinephrine at 0.5 mcg/kg/min. The patient's weight is 120 pounds. Calculate the infusion rate if the concentration is 5000 mcg in 1000 mls. Then you need the patient's weight in the question.

But if the question reads: A patient is receiving epinephrine at 3mcg/min. The patient's weight is 120 pounds. Calculate the infusion rate if the concentration is 5000 mch in 1000mls. In this question, since the doseage is set and not based on the weight, the patient's weight is irrelavent.
