Can someone help me with this dosage calculation?????

100 mg : 1mL : 750 mg : X mL multiply 1 x 750 and divide by 100. X= 7.5 mL

this is the way I would figure it. Good Luck!

thanks so much for helping me

100 mg : 1ml : 750 mg : x ml multiply 1 x 750 and divide by 100. x= 7.5 ml

this is the way i would figure it. good luck!

750mg ok kefurox must be prepared. a 1.5g vial of kefurox in powered form is available. directions for reconstitution state: add 14 ml of diluent to yield 100 mg in 1 ml. after reconstituting the drug as directed, how many ml should you withdraw from the vial?

ordered

avail (after you reconstitute) - don't get confused with the reconsitution directions

x = what are they asking for?

o 750mg dose

a 100mg per ml

x = ml/dose to give

ml = 1 ml x 750mg = (750)(1) = 7.5ml/dose

dose 100 mg dose (100)

our school teaches us to use dimensional analysis and here it is in a nutshell:

1. begin with the end in mind: what do you want to end up with? what is the question asking? in this case, they are asking "what dose [ml/dose] are you going to take to the bedside?"

2 - the numberator must match the numberator of what you are looking for. in this case ml.

3. after you set up your first part of the formula, you leap frog the labels - so you match whatever was in the denominator to the numberator

4. cancel out until you end up where you want to be:

5. end where you began. you cannot stop the equation until you get everything to cancel out except what you were originally looking for.

it sounds harder than it is, but look it over as i set it up according to the steps above:

1. begin with the end in mind: what do you want to end up with? what is the question asking? in this case, they are asking "what dose [ml/dose] are you going to take to the bedside?"

ml

dose

2 - the numberator must match the numberator of what you are looking for. in this case ml.

ml = 1 ml

dose 100 mg

3. after you set up your first part of the formula, you leap frog the labels - so you match whatever was in the denominator to the numberator

ml = 1 ml x 750mg

dose 100 mg dose

4& 5. end where you began. you cannot stop the equation until you get everything to cancel out except what you were originally looking for.

** means that you cancel these out - i cannot strike out on the computer

ml = 1 ml x 750** = (1)(750) ml

dose 100 ** dose (100) dose

now that it is all set up, and you are able to end where you began, you just have to calculate the math:

ml = 1 ml x 750mg = (750)(1) = 7.5ml/dose

dose 100 mg dose (100)

well, the spacing did not work out when it posted, sorry

if you write it out, then you can make the spacing look right and it will make sense.
