Question: 1 / 400

What is the BMI of a female client who weighs 154 pounds and is 5'6"?

24.8

To calculate the Body Mass Index (BMI), the formula used is:

BMI = weight (kg) / (height (m))^2.

First, we need to convert the weight from pounds to kilograms and height from feet and inches to meters.

1. The weight of the client is 154 pounds. To convert pounds to kilograms, you divide by 2.205:

- 154 lbs / 2.205 = 69.9 kg (approximately).

2. The height of the client is 5 feet 6 inches. To convert feet and inches to meters:

- Convert feet to inches: 5 feet × 12 inches/foot + 6 inches = 66 inches.

- Convert inches to meters: 66 inches × 0.0254 meters/inch = 1.6764 meters (approximately).

Now using the BMI formula:

BMI = 69.9 kg / (1.6764 m)² = 69.9 / 2.805 = 24.9 (approximately).

Rounding this result gives a BMI of around 24.8, which corresponds to the first choice.

This value indicates that the client falls within the "normal weight"
