The nurse identifies an electrolyte imbalance, an elevated blood pressure, and a weight gain of 4.4 lbs (2 kg) in 24 hours for a client with hepatic failure. Which intervention should the nurse include in the plan of care?

A. Provide only distilled water. Providing only distilled water is not appropriate in this situation. The client's weight gain and electrolyte imbalance indicate the need for careful monitoring and intervention, but restricting fluid intake to distilled water alone may not address the underlying issues adequately. B. Document abdominal girth. Documenting abdominal girth is important to assess for signs of ascites, which can occur in hepatic failure. A sudden weight gain and elevated blood pressure may indicate fluid retention, and documenting abdominal girth can provide additional information about fluid accumulation in the abdomen. C. Offer a high protein diet. While nutritional support is important for clients with hepatic failure, offering a high protein diet may not be appropriate if the client has an electrolyte imbalance. Protein intake should be balanced and monitored carefully to avoid exacerbating the imbalance. D. Use a cushion when sitting. Using a cushion when sitting may be beneficial for comfort, but it does not directly address the identified issues of electrolyte imbalance, elevated blood pressure, and weight gain. The priority is to assess and address these concerns through appropriate interventions such as documenting abdominal girth and addressing fluid retention.
