A doctor order 400 mg of rocephin IV to be given to a 40.8lbs child every 6 hours available is rocephin 100mg in 20ml normal saline the medication label show that 75-150mg/kg per day ia the appropriate dosage rang is this doctor order appropriate if ao how much should be administered dose

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

only 10/60 isn't equivalent

hope this : )
