Beth: To find gtt/min you will need a drop factor! Are you certain the problem

doesn't state a drop factor?

problem.......

A 160 pound man is admitted to the hospital. The

order states that the patient is to receive 7.5mg/kg

of Etidronate in 1000 ml of D5W over 24 hrs. The drug

comes in a 300 mg vial which is diluted with 10ml of

sterile water.

A Patients weight in Kilograms 72.73

B Total mg of drug / day 545.5

C ml of drug / 1000ml D5W

D gtts/min

I got A and B, but please explain to me, as if I was

10 yrs old, how to figure out C and D. I have the

answers in my book, but have been sitting here for

hours trying to come up with how the answers were

figured out. Is there a method that would figure it

all out together, or do I have to come up with a

problem for each question?

thanks for any help

Beth,

Hope this makes sense:

A 160 pound man is admitted to the hospital. The

order states that the patient is to receive 7.5mg/kg

of Etidronate in 1000 ml of D5W over 24 hrs. The drug

comes in a 300 mg vial which is diluted with 10ml of

sterile water.

A Patients weight in Kilograms

2.2 lbs = 1 kg

160 lbs = ? kg

? = 72.73

B Total mg of drug / day

7.5mg/kg * 72.73 kg = 545.48 mg/day

C ml of drug / 1000ml D5W

(although some will discount the 10ml of sterile water, I tend to use

everything unless told otherwise)

300mg of drug in 10ml of water into 1000 ml of D5W

= 300mg of drug in 1010 ml of D5W

= ? mg in 1000 ml of D5W

297 mg in 1000 ml of D5w

So patient needs 545.48/297 * 1000 = 1836.63 ml/day

D gtts/min

If 20 drops in 1 ml =

1836.63 ml per day * 20 drops per ml =

36732.6 drops over 24 hours = (36732.6 divided by 24 hours in one day)

1530.53 drops per hour = (1530.53 divided by 60 minutes in one hour)

25.51 drops per minute

There are a bunch of questions, and this is just one

of them. At the beginning, it does state 60gtt/min

sorry, I forgot.

Dear Beth,

You will find this type of problem VERY much outlined in my IV Flow Rate

Tutorials. Much of the problem of not finding a tutorial stems from the fact

that every book calls specific problems by a different name.

Hope this helps . Please visit theTutorial - 1 Math folder Tutorial - IV

Flow Rates.

Also you will find the weith problems on this site as w well.

Resepctfully,

Abe,

I just kind of presumed that they were asking how many drops per minute

should the flow be set to, because I have seen questions like that.
