The formula to calculate the Child's Dosage (Dc) using Clark's Rule is:
\[ Dc = \frac{W \times Da}{150} \]
Where:
Clark's Rule is a medical formula used to calculate the appropriate dosage of medication for children based on their weight. The rule assumes that the average adult weight is 150 pounds and uses this to proportionally adjust the dosage for a child. It is important in pediatric medicine to ensure that children receive the correct dosage of medication relative to their size. However, it is important to note that Clark's Rule may not be applicable for all medications and situations, so it should be used with caution and under the guidance of a healthcare professional.
Let's consider an example:
Using the formula to calculate the Child's Dosage (Dc):
\[ Dc = \frac{50 \times 200}{150} = \frac{10000}{150} = 66.67 \, \text{mg} \]
This means that the appropriate dosage for the child, based on Clark's Rule, is 66.67 mg.
