A patient weighs 50 kg and is 1.65 m tall. Which BMI category does this place the patient in?

Answer and explanation

Correct answer: A. underweight

  1. Step 1: BMI = weight / height^2 = 50 / 2.7225 = 18.4 kg/m^2.
  2. Step 2: Standard categories: under 18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, 30 or more obese.
Answer
underweight.
Why not the others: 'normal weight' does not match the calculated BMI of 18.4 kg/m^2; 'overweight' does not match the calculated BMI of 18.4 kg/m^2; 'obese' does not match the calculated BMI of 18.4 kg/m^2.
