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?

Understanding the problem: Original weight: 90.7 kg Weight lost: 6.8 kg Calculating the percentage weight loss: Calculate the ratio of weight lost to original weight: 6.8 kg / 90.7 kg Convert the ratio to a percentage: (6.8 kg / 90.7 kg) x 100% Solving the equation: (6.8 kg / 90.7 kg) x 100% ≈ 7.5%
