Dear Jim:
1. 89.8 kg X 2 X 10= 1,796ml.
2. Cat=8.16 kg.
2 mg X 8.16= 16.32 mg/10 ml= 1.632 ml. for the cat.
3.1 g.= 1000 mg. Then if you enjoy 1g per 15 ml.
the patient requests 15 ml.
4.one tablet= 5 mg.
7.5 mg. X56.69 kg. then for one kg.=0.132 mg. X kg.
5. 2000 ml. = 100% ,after if you need 1%= 20 g. of drug.
This is uncomplicated math dude.
Try using ratios
mg drug/volume= x mg drug/vol
Change regular avoir dupois weights to metric back calculating, set up ratios and afterwards convert. Make sure all your metric values are adjectives; mg to mg not g to mg.
BTW, 1% solution is 1 gram per 100 mL so do a ratio to convert.
If I do the math for you, you won't learn, and you might shoot someone by giving a wrong dose.
Hey, I go an "A" within dosage calc and so can you. This is so straight forward you will kik yourself.
