A nurse is discussing weight loss with a client who is concerned about losing 6.8 kg (15 lb) from an original weight of 90.7 kg (200 lb). The nurse should identify the weight loss as which of the following total percentages?
A.
7.5%
B.
8.1%
C.
13.3%
D.
15%
To determine the percentage of weight loss, use the formula:Percentage of weight loss=(Weight lossOriginal weight)×100\text{Percentage of weight loss} = \left( \frac{\text{Weight loss}}{\text{Original weight}} \right) \times 100Percentage of weight loss=(Original weightWeight loss)×100
Given:
- Weight loss = 6.8 kg
- Original weight = 90.7 kg
Calculate the percentage:Percentage of weight loss=(6.890.7)×100≈7.5%\text{Percentage of weight loss} = \left( \frac{6.8}{90.7} \right) \times 100 \approx 7.5\%Percentage of weight loss=(90.76.8)×100≈7.5%
Thus, the correct answer is:
A. 7.5%
