question 16

Multiple Choice

When calculating dosages for infants and children, why are calculations using body surface area (BSA) thought to be more accurate than those that use body weight alone?

• A) BSA is calculated using the square root of a number, which is more complex and therefore more accurate.
• B) BSA is proportional to an individual's metabolic rate and correlates well with organ size.
• C) BSA requires rounding the answer to one decimal place, or the tenths place, so that the child does not receive too much medication.
• D) BSA is based on centimeters and kilograms, which are metric measurements and are more accurate.
