Which actions should the nurse take when calculating and administering weight-based pediatric medication dosages? (Select all that apply)

A. Use the current weight obtained during the visit is correct because pediatric medication dosages are calculated based on the child’s most recent weight. Using an accurate, current weight ensures the dose is appropriate and safe, as even small weight differences can significantly impact pediatric dosing and reduce the risk of underdosing or overdosing. B. Administer the medication dose based on the nurse's estimation is incorrect because estimation is unsafe and unreliable. Pediatric doses must be calculated precisely according to weight and recommended mg/kg guidelines. Guessing or estimating can lead to serious medication errors. C. Convert the weight to kilograms if it is recorded in pounds is correct because most pediatric dosing guidelines use kilograms, not pounds. Accurate conversion is essential for correct dose calculation and safe medication administration. D. Round the weight down to a whole number for easier calculations is incorrect because rounding the weight down can result in underdosing, which may reduce therapeutic effectiveness. Standard practice is to use the weight to at least one decimal place to maintain dosing accuracy. E. Use a previous weight documented during the last visit is incorrect because the child’s weight can change rapidly, especially in infants and young children. Using outdated weights risks inaccurate dosing and potential harm.
