(d) 35 kg +- 1kg/2.5cm above or below 150 cm in height

I got this question in an online interview.

The doubt is from Pharmacokinetic Principles Applications topic in section Applications of Pharmacokinetic Principles, Diuretics, Drug Concentration and Pharmacologic Response of Drug Biotechnology

Answer 1

The correct choice is (a) 50 kg +- 1kg/2.5cm above or below 150 cm in height

For explanation: The volume of distribution of drug gets affected by the changes in body weight. Since increase in the body weight is directly related to the volume of various fluids. The ideal body weight of a man can be calculated by 50 kg +- 1kg/2.5cm above or below 150 cm in height and for woman 45 kg +- 1kg/2.5cm above or below 150 cm in height. Any person whose body weight is more than 25% and above the IBW is considered to be obese.
