What is the most appropriate statement the nurse can make to a client who gained 1.36 kg (3 lb) in a week on a weight management program?

The most appropriate statement the nurse can make is to inquire about any issues the client may have faced that week that could have impacted their focus on the diet. This approach shows empathy and support, encouraging open communication and allowing the client to reflect on their experience. It can lead to a constructive discussion about potential barriers to adherence to the weight management program.

By exploring the client's circumstances, the nurse may uncover specific challenges or situations that contributed to the weight gain, such as emotional stress, social events, or other factors that may have influenced dietary choices. This supportive dialogue fosters a trusting nurse-client relationship and empowers the client to address any obstacles in their weight loss journey more effectively.

The other options do not promote a helpful interaction as they could come across as judgmental or prescriptive without understanding the individual's situation. While normal fluctuations in weight can occur, acknowledging the client's personal experience and offering guidance based on that insight is essential for creating a more effective plan tailored to their needs.
