Clark's Rule is commonly used to calculate the childresn's dosage of medication:

Clark's Rule is: C=A x W/150

Use the rule to calulate thr problem

C- child's dose
A= adult's dose
W=weight of child in pounds

How much would a child need to weigh to receive the adult dosage if the adult dosage 80 cc?

Ask yourself the question in a different way — how could you manipulate the weight factor, so C = A?

I'll let you think about it.

I hope this helps. Thanks for asking.

To calculate the weight of the child needed to receive the adult dosage, we can rearrange Clark's Rule formula:

C = A x W/150

Given:
C (child's dose) = Adult dosage = 80 cc
A (adult's dose) = 80 cc

We need to find the weight of the child (W).

Rearrange the formula to solve for W:

W = (C x 150) / A

Substitute the values into the formula:

W = (80 cc x 150) / 80 cc

The cc units cancel out, leaving us with:

W = 150

Therefore, the child would need to weigh 150 pounds to receive the adult dosage of 80 cc.
