Important tools used to calculate the correct dosage of drugs for children include body weight and:
A. height
B. gender
C. body surface area
D. metabolism
c
Rationale: Body surface area is a critical tool in calculating pediatric dosages because it gives the best overall accuracy when determining how much of a drug to administer. Height is a component of a child's size, but it is not used by itself in determining dosages; gender is never used for this purpose in children; and metabolism is only taken into account for drug dosages in the case of extremely specific conditions, such as whether the child has a kidney or liver disease.
