Which laboratory finding for a client with Crohn's disease hospitalized for diarrhea is most concerning?

• A. Hemoglobin level of 12 g/dL
• B. Total protein level of 3.8 g/dL
• C. White blood cell count of 10,000/uL
• D. Electrolytes within normal limits

Answer: (B)

A total protein level of 3.8 g/dL is concerning in a client with Crohn's disease who is hospitalized for diarrhea because it indicates potential protein malnutrition and inadequate nutritional status. In patients with Crohn's disease, especially those experiencing diarrhea, there is a risk of significant protein loss and malabsorption. This low total protein level can lead to various complications, such as edema, compromised immune function, and delayed wound healing, which are especially critical in a hospital setting.

The measurement of total protein is crucial as it reflects the overall state of nutrition and can provide insight into the presence of conditions such as hypoalbuminemia, which often occurs due to malabsorption and inflammation present in Crohn's disease. Managing malnutrition is vital in the treatment of Crohn's disease, as it can exacerbate the patient's condition and impede recovery.

In contrast, a hemoglobin level of 12 g/dL, while it may suggest mild anemia, is not as critical as the effects of low total protein. A white blood cell count within normal limits indicates that there isn’t an acute infection, and electrolytes being normal suggests that there is currently not a significant electrolyte imbalance, which is often a concern in patients with severe diarrhea.
