is medicine doses based on patient's weight a linear relation. If it is what is the dependent and independent variable?
Yes it is....generally the dosage is listed as x mg/kg x mg per kg of body weight
so the independent variable is the dosage x mg/kg as it never changes....what does change is the WEIGHT of th patient from patient to patient .....so patient weight would be the DEPENDENT variable....how much they get as a dose DEPENDS on how much they WEIGH ....
That is not correct EP
How much medicine the patient is given depends on how much they weigh
the wieght is the INDEPENDENT variable and
the dose is the DEPENDENT variable. (it depends on the weight)
Hmmmm..... the dosage is constant say 5 mg/kg the DOSE is variable dependent on weight (which is variable)
so I guess it depends on a slight wording difference whether we are talking dose or dosage (which unfortunately are sometimes used interchangeably)
For a GIVEN PATIENT DOSE would be variable between different medicines based on dosages
For a GIVEN MEDICINE dosage would be constant and patient weight would be variable ....
a conundrum...don't you think?
Nah! I am going to change my mind (again) and say "Yes, Melody, you are correct'
I think I even said it in my first answer
DOSE would be the y coordinate m would be the DOSAGE 'x' would be patient weight and b would be any applicable loading dose
dose = dosage x wt + load would make dose the dependent and weight the independent variable
Thanx ! G'Day !
