Posted over 2 years ago Hello all I have this drug calculation problem that I need some one to work out for me. You are asked to administer an infusion of isosorbid Dinitrate 50mgs in 500ml of glucose 5% at a rate of 2mg / hour to a patient. - Calculate the rate in ml/hour - After four hours the rate is changed to 3.5 mgs per hour What is the new rate?

| Posted over 2 years ago the first rate is 20ml/hr then changing to 35ml/hr, because the concentration is 1mg/10ml. Does this help? |

| Posted over 2 years ago Yeah that is a pretty simple one really. Honestly you shouldn't even need a calculator for that one,so if you are sturggling with this sort of calculation, I suggest you brush up on your maths! |

| Posted over 2 years ago I don't think the last post was very helpful... just because you can post anonymously doesnt mean you shouldn't be careful in the way we talk to each other. Having worked for many years teaching both nurses and doctors who struggle with drug calculations I know that for some people even the simpler calculations need a lot of thought and effort- some people find these things easy and others don't and it isn't necessarily about maths ability- often it's about being able to visualise the problem in a way that makes sense to the individual- that's why I liked the original answer because it tried to help the poster make sense of the calculation rather thatn just applying the maths.

Just reading through these posts as I'm a new member and this response is one that makes my blood boil. The old saying that 'nurses eat their own' is in evidence here. Why do some people have to be so ungracious and downright nasty. Isn't it more helpful and may I say professional and caring to offer constructive advice rather than the sneering retort here. After all the answer had been given in good faith and with good grace so the response was redundant anyway. I'd say 'brush up on your manners' to that respondent!!! |

| Posted about 1 year ago sometimes I get confused with numbers, this does not mean im inferior or worthy of any less respect. Surely we all need to help each other and work together for the sake of the individuals we care for instead of making nasty comments?! |

| Posted about 1 year ago Hi there, Lots of people have problems with numbers, a sort of dyslexia with numbers, rather than letters, if you like.It has no bearing on your competence as a nurse.Being a good nurse means having a multitude of personal and practical skills as we all know.If you have hit a mental block with the drugs calculations, why not get someone to sit down with you and go over it in-depth, and I'm sure there are online resources you can practise on if you google it.I'm sorry you didn't get the support you were after coming on here initially.Best of luck. |

| Posted about 1 year ago How do you calculate in mL per hour when the dose is given in micrograms per minute? (infusion rate calculation) Glyceryl trinitrate is prescribed at 10 micrograms per min, you have a solution of 50mg in 500mL. How fast do you set the pump? |
