A nurse is caring for a client who has chronic venous insufficiency. Which of the following areas should the nurse assess for the presence of a venous ulcer?

Rationale:

• Hepatic encephalopathy: This is caused by the buildup of neurotoxins, particularly ammonia, due to impaired liver function. The client’s elevated ammonia level and history of chronic alcohol use and jaundice support this diagnosis. Early signs may include confusion and lethargy, progressing to coma if untreated.
• Uremic encephalopathy: This condition is caused by accumulation of urea and toxins due to kidney failure. There is no evidence in the case of renal impairment, such as elevated BUN or creatinine levels, making this diagnosis unlikely in the current context.
• Hypoglycemia: Low blood glucose can cause confusion or altered mental status, but this client’s symptoms and labs do not indicate hypoglycemia. There is no mention of a low glucose level, and the focus of concern is more aligned with liver failure than endocrine causes.

• Abdominal pain: Although abdominal pain is a relevant symptom in liver disease, it is nonspecific and not directly responsible for hepatic encephalopathy. It reflects general liver inflammation or ascites but does not cause neurologic symptoms on its own.
• Albumin 3.0 g/dL: Low albumin indicates reduced liver synthetic function and contributes to fluid shifts like ascites, but it is not neurotoxic. It does not directly cause hepatic encephalopathy or altered mental status.
• Ammonia 150 mcg/dL: This is a critically elevated value, more than double the normal upper limit. High ammonia levels are the most direct biochemical cause of hepatic encephalopathy and require immediate treatment to prevent worsening neurological decline.
• Total Bilirubin 2.0 mg/dL: While elevated bilirubin suggests cholestasis and impaired liver clearance, it leads to jaundice rather than mental status changes. It reflects liver dysfunction but is not the key factor in encephalopathy development.

Rationale:
A. Continuous passive motion device: This device is typically used following total knee arthroplasty to maintain joint mobility and prevent stiffness. It is not commonly indicated after total hip arthroplasty, where excessive hip movement is discouraged during early recovery.

B. Elevated toilet seat: An elevated toilet seat helps prevent excessive hip flexion, which reduces the risk of hip dislocation after surgery. It allows the client to sit and stand more safely without bending the hip beyond 90 degrees, which is a critical precaution following hip arthroplasty.

C. Trapeze bar: A trapeze bar may assist some clients in repositioning while in bed, but it is not a standard discharge requirement for hip arthroplasty. Its use is more common in inpatient rehabilitation or in clients with prolonged immobility.

D. Compression garment: While compression stockings may be used to reduce the risk of deep vein thrombosis (DVT), a compression garment is not a standard or essential piece of home equipment following hip replacement surgery unless specifically indicated by the healthcare provider.
