In assessing an adult client, the nurse calculates the body mass index (BMI) as 14 kg/m2. Which nursing problem should be included in this client's plan of care? Reference Range:

A. Imbalanced nutrition, less than body requirements. A BMI of 14 kg/m² is significantly below the normal range (18.0–24.9 kg/m²) and indicates undernutrition or malnutrition. This suggests inadequate caloric or nutrient intake, making this the most appropriate nursing problem for the client’s care plan. B. Excess fluid volume. Excess fluid volume is associated with conditions like heart failure, kidney disease, or liver dysfunction, often leading to weight gain and edema. A BMI of 14 suggests undernutrition rather than fluid overload. C. Imbalanced nutrition, greater than body requirements. This diagnosis applies to clients who are overweight or obese (BMI ≥25 kg/m²). Since the client’s BMI is severely low, this option is incorrect. D. Deficient fluid volume. While dehydration can contribute to weight loss, a low BMI primarily indicates chronic malnutrition rather than acute fluid loss. Further assessment of hydration status would be needed to determine if fluid volume deficit is also a concern.
