Can someone help me with these math problems?

your client is receiving 1000 ml. of lactated ringers solution iv at the rate of 50 ml. per hour. your iv drip factor is 20 gtts. per minute.
at how many drops per minute should the drip rate be?
how long will this iv last?
shouldn't the drip factor be 15 gtts/min? i thought that was standard?
the gtt factor is different for different types of tubing. your question already tells you that it's 20, otherwise, you would look at the package to find it. i solve for a drip factor using volume x gtt factor/time in mins.
to figure out how long it will last, your question already tells you how many ml/hr the fluid is running. so, how many hours will a 1000 ml bag take to empty if there are 50 ml going each hour?
the nurse is to administer 0.1 mg hydromorphone (dilaudid) iv for a client’s pain every 4-6 hours. prn for severe pain.
what is the maximum dose in 24 hours?
what is the minimum dose in 24 hours if used as ordered?
when the 0.1 mg is diluted in 4 ml of d5w, the total amount to be delivered iv push is 5 ml. over 2 minutes. how many mls. will be given in 30 seconds?
to find the daily range, first figure out how many doses the patient would get if it's given every 4 hrs and every 6 hrs. multiply the number of doses by the amount of the dose (0.1 mg) to find the daily max and min.
the next part of the question is asking about how quickly you can safely push the drug after it's diluted. the question already tells you that after dilution, you will be giving a total of 5 ml over 2 mins (ie. you will slowly push syringe). first, figure out how many seconds are in 2 mins, because you want to find the dose that you will have given in 30 sec. so, you know that you are giving 5 ml in 120 sec, now set up a ratio to find out how many ml you will have given in the first 30 sec of your 2 min push. 5:120 = x:30.
i am so confused. i don't think these are worded very good. can someone help me figure them out? i would be forever grateful.

hope this helps the wording make more sense for you!

50x20 / 60min = 17 gtts/min?

and it'll run for 20 hours?

to find the daily range, first figure out how many doses the patient would get if it's given every 4 hrs and every 6 hrs. multiply the number of doses by the amount of the dose (0.1 mg) to find the daily max and min.

max- 0.1x6 = 0.6?

min- 0.1x4 = 0.4?

and you can give 1.25 mls in 30 seconds? is that right?

thanks so much for your help!! :yeah: :redbeathe
