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: Underweight: BMI is less than 18.5; Normal weight: BMI is 18.5 to 24.9; Overweight: BMI is 25 to 29.9; Obese: BMI is 30 or more

Choice A Reason: Fluid volume excess is incorrect. Fluid volume excess refers to an overabundance of fluid in the body, leading to symptoms such as edema, weight gain, and hypertension. However, a BMI of 14 kg/m^2 indicates underweight, not fluid volume excess. Therefore, this choice is incorrect. Choice B Reason: Unbalanced nutrition, less than body needs is correct. A BMI of less than 18.5 indicates underweight according to the provided reference range. Underweight individuals often do not consume enough nutrients to meet their body's needs, leading to potential nutritional deficiencies. Therefore, the nursing problem of "Unbalanced nutrition, less than body needs" is appropriate for addressing the client's low BMI. Choice C Reason: Unbalanced nutrition, greater than body needs is incorrect. This choice would be more applicable if the client's BMI indicated overweight or obesity, as it suggests an excess intake of nutrients relative to the body's needs. However, a BMI of 14 kg/m^2 indicates underweight, not excess weight. Therefore, this choice is incorrect. Choice D Reason: Fluid volume deficit is incorrect. Fluid volume deficit refers to a decreased amount of fluid in the body, leading to symptoms such as dehydration, decreased urine output, and hypotension. However, a low BMI does not necessarily indicate fluid volume deficit; it primarily reflects undernutrition. Therefore, this choice is incorrect.
