Which statement shows that a patient instructed to increase protein in her diet needs further guidance?

The statement indicating a need for further guidance focuses on the protein source. While yogurt does contain protein, it may not provide sufficient amounts compared to other protein options, especially in the context of needing to significantly increase protein intake. A balanced breakfast ideally should include a variety of protein sources, and eggs are a well-known high-protein food. The patient's choice to exchange eggs for yogurt suggests a potential misunderstanding of adequate protein sources necessary for her dietary needs.

In contrast, the other statements showcase appropriate approaches to increasing dietary protein. Adding nuts to salads, consuming beans as a meat substitute, and incorporating more fish illustrate effective strategies for diversifying protein sources and ensuring that the patient is likely meeting her increased protein requirements more effectively. Each of these alternatives contains substantial protein and would contribute positively to her overall nutrition strategy.
