Using friend's rule the average adult dose of a particular med is 10 mg what is the appropriate dose of a this medication for a child who is 11th months of old?

To calculate the appropriate dose for an 11-month-old child using Clark's rule, you would first determine the child's weight in pounds. Assuming an average weight of about 20 pounds for an 11-month-old, you would use the formula: (Child's weight in lbs / 150) x Adult dose. Therefore, the calculation would be (20/150) x 10 mg, which equals approximately 1.33 mg. Always consult a healthcare professional before administering any medication to a child.
