Math Problem Help!!!!

The order is for 250ml of 0.45% of Sodium Chloride over 4 hours. You have microtubing at 60 gtt/min available. What is the gtt/min?

I tried so many times and I cannot get this

would it change your calculations any to know that micortubing is 60 gtt/mL and not 60 gtt/min?

tubing is in drops/mL not drops/ min

If you need to 250 mL over 4 hours, How many mL per hr.?

Divide that number by 60 to get mL/ min

multiply by the drip rate. to get drops/mL

If you really think it through you can go step by step.

Your tubing is rated by drops per ml and you need to know how many gtts per minute.

So how many minutes will it run? 4 hours x 60 minutes = 240 minutes

How many ml per minute? 250 ml fluid / 240 minutes = 1.04 ml per minute

Soooo 60 gtts = 1 ml and I need 1.04 ml per minute so 60 x 1.04 = 62 gtts/minute

It is best to let the OP show their work before giving the answer. It helps to find out where in their calculation they are messing up and then guide them. Giving them the answer without effort on their part does not help them when they need to do it for a test.

Don1984,

Absolutely true. I don't usually answer student questions but I'm a bit of a math nerd and didn't think.

Glad it turned out to be a teacher typo causing the issue!

And now I must refrain from future med calc questions.....guess I'll wait for my little sister to start college algebra.
