Given that Clark's formula is \(D = \dfrac{{kA}}{{70}}\) where: \(D =\) the dosage in ml for children of any age . \(k =\) the child's weight in kilograms. \(A =\) the adult dosage in ml .Given the adult dosage is 20 ml, for a child of weight 21 Kg the dosage according to Clark's formula is ?

Given that Young's formula is \(D = \dfrac{{yA}}{{y + 12}}\) where: \(D =\) the dosage in ml for children between the ages of 1 and 12 years. \(y =\) the age of the child in years, \(A =\) the adult dosage in ml. Given the adult dosage is 24 ml, for a child 6 years old the dosage according to Young's formula is?

Given that Clark's formula is \(D = \dfrac{{kA}}{{70}}\,\) where: \(D =\) the dosage in mg for children of any age. \(k =\) the child's weight in kilograms, \(A =\) the adult dosage in mg .The adult daily dosage of medicine contains 1470 mg. A child who weighs 24 kg is to be given tablets containing 168 mg of this medicine. How many tablets should this child be given daily?

Given that Young's formula is \(D = \dfrac{{yA}}{{y + 12}}\) where: \(D =\) the dosage in ml for children between the ages of 1 and 12 years. \(y =\) the age of the child in years, \(A =\) the adult dosage in ml. A child's dosage is calculated to be 6 mg, based on an adult dosage of 30 mg. How old is the child in years?

There is 50 mg of vitamin C in 100mL of orange juice. A doctor told Jim that he needs to take 1000 mg of vitamin C every day.

a) How much orange juice would he need to drink in order to achieve this?

b) Calculate the amount of orange juice he needs using the formula below:

\[\text{volume required (mL)}=\dfrac{\text{strength required (mg)}}{\text{stock strength (mg)}} \times \text{volume of stock(mL)}\]

John is 4 years old and weighs 18 kg. He needs to take some cough medicine. The adult dosage is 50 mg. What dosage should he take:

a) Using Young’s rule

b) Using Clark ’s rule

\(\text{Young’s rule:  Dosage}=\dfrac{\text{age of child (years)} \times \text{adult dose}}{\text{age of child (years)} +12}\)

\(\text{Clark ’s rule:  Dosage}=\dfrac{\text{weight (kg)} \times \text{adult dose}}{70}\)

Given that Fried's formula is \(D = \dfrac{{mA}}{{150}}\,\,\) where: \(D =\) the dosage in ml for children between the ages of 1 and 2 years. \(A =\) the adult dosage in ml. \(m =\) the child's age in months .Given that the adult dosage is 30 ml, for a child 15 months old the dosage according to Fried's formula is ?

Given that Clark's formula is \(D = \dfrac{{kA}}{{70}}\) where: \(D =\) the dosage in ml for children of any age. \(k =\) the child's weight in kilograms. \(A =\) the adult dosage in ml. Given the adult dosage is 20 ml, for a child of weight 21 Kg the dosage according to Clark's formula is?

Given that Young's formula is \(D = \dfrac{{yA}}{{y + 12}}\) where: \(D =\) the dosage in ml for children between the ages of 1 and 12 years. \(y =\) the age of the child in year, \(A =\) the adult dosage in ml. Given the adult dosage is 20 ml, for a child 8 years old the dosage according to Young's formula is?
