Which nursing diagnosis would be appropriate for Mari due to her cognitive impairment?

The appropriate nursing diagnosis for Mari, considering her cognitive impairment, focuses on her nutritional needs and dietary habits. Cognitive impairment can significantly impact an individual's ability to recognize hunger cues, prepare meals, or even remember to eat. As a result, this patient might consume fewer nutrients than her body requires, leading to the classification of "Imbalanced nutrition: less than body requirements."

This diagnosis indicates that due to cognitive challenges, Mari is likely unable to maintain adequate nutritional intake, which is essential for her overall health, strength, and well-being, especially if she has difficulty independently managing her dietary needs. Identifying this issue early helps in formulating an effective care plan aimed at improving her nutrition and ultimately enhancing her quality of life.

In contrast, while the other options pertain to various health concerns, they do not directly address the specific risks associated with her cognitive challenges in relation to nutrition intake. For instance, the risk for electrolyte imbalance may not connect as directly to cognitive impairment, and the diagnoses regarding imbalanced nutrition (greater or lesser than body requirements) are both focused on quantity but would depend on how her condition specifically affects her eating habits. Therefore, recognizing the potential for less nutritional intake due to cognitive impairment is vital in this scenario.
