A prescriber is adjusting doses of a particular drug. A nurse understands that the most accurate dose determination can be calculated based on the
a. drug's pharmacokinetics.
b. patient's gender.
c. patient's basal metabolic index (BMI).
d. patient's body surface area.
ANS: D
Body surface area is the most accurate method of dose determination and/or adjustment.
Pharmacokinetics involves absorption, distribution, metabolism, and excretion, but it is not specific to drug dosing.
A patient's gender is not the most accurate method of dosing, because each individual is different.
The BMI is an indication of weight and height proportions, not an accurate determinant of drug dosing.
