Question

Mrs. Mary Smith is a 70-year-old old white woman who is 5 ft and 4 inches tall and weighs 100 pounds. She was recently admitted to the medical unit.

Answer 1

Answer:

Step:1 - Convert all the value to S.I unit

• Feet to Metres
  • 1 foot = 0.3048
  • Therefore, 5 feet = 5 * 0.3048 = 1.52 metres------- (1)
• Inches to Metres
  • 1 inch = 0.025 metres
  • therefore, 4 inchs = 4 * 0.025 = 0.1 metres----------(2)
• The height of this patient in metres is = (1) + (2) = 1.52 + 0.1 = 1.62 metres
• Pounds to Kilos
  • 1 pound - 0.45kg
  • therefore, 100 pounds = 0.45 * 100 = 45kg
• The formula for Body Mass Index = Body weight (kgs)/ ( height in metre)2
• BMI = 45 kgs / 1.62 metres *1.62 metres
  • = 45/ 2.62
  • 17.17 kg/m2

The BMI of this patient is 17.17 kg/m2
