A client weighs 88 kg and is 1.61 m tall. Using BMI = mass / height², what BMI should be recorded? Round to one decimal place.
- A27.3 kg/m²
- B34.4 kg/m²
- C33.9 kg/m²
- D54.7 kg/m²
Show answer and explanations
Answer
C
Height squared = 1.61 × 1.61 = 2.5921 m²; BMI = 88 / 2.5921 = 33.9 kg/m².
A
This divides by 2 × height (3.22) instead of height squared.
B
This rounds height to 1.6 m before squaring (88 / 2.56 = 34.4 kg/m²), which shifts the result.
D
This divides mass by height (88 / 1.61) without squaring it.
C
Height squared = 1.61 × 1.61 = 2.5921 m²; BMI = 88 / 2.5921 = 33.9 kg/m².
