Which of the following is a primary action of entacapone when used with levodopa for clients with Parkinson's disease?

The emergency management of this client presenting with altered mental status, hypotension, tachycardia, elevated lactate, leukocytosis, and signs of dehydration whose findings suggest hypovolemic shock or possible septic shock, both of which require rapid stabilization of circulation and treatment of the underlying cause. Priority interventions aim to restore perfusion, support blood pressure, and treat infection if present. Understanding when to give fluids, vasopressors, antibiotics, or avoid diuretics is essential in critical care nursing.

Rationale:

• Initiate vasopressor therapy to manage hypotension: Vasopressors are not first-line treatment when hypotension is due to hypovolemia, as in this client with dry mucous membranes, elevated BUN, and decreased oral intake. The priority is to restore intravascular volume with fluids first. Using vasopressors prematurely can worsen tissue perfusion by constricting vessels without correcting the underlying volume deficit.

• Administer IV fluids to increase intravascular volume: The client shows clear signs of volume depletion, including hypotension, tachycardia, dry mucous membranes, elevated BUN, and altered mental status. IV fluids are the first-line intervention to restore circulating volume and improve perfusion. This helps correct hypotension and supports organ function. Fluid resuscitation is essential in suspected hypovolemic or septic shock.

• Administer diuretics to reduce fluid overload: There is no evidence of fluid overload in this client; instead, the findings indicate dehydration and poor perfusion. Diuretics would further reduce circulating volume and worsen hypotension and shock. This could lead to decreased organ perfusion and increased risk of organ failure. Therefore, diuretics are unsafe and inappropriate in this scenario.

• Provide antibiotics for suspected septic shock: The elevated WBC count, increased lactate level, altered mental status, and hypotension raise concern for possible sepsis. Early antibiotic administration is critical in suspected septic shock to control infection and prevent progression to multi-organ failure. Even while fluid resuscitation is ongoing, antibiotics should be initiated promptly if infection is suspected. This is a time-sensitive, life-saving intervention.

Liver cirrhosis is a progressive, irreversible condition characterized by fibrosis, scarring, and architectural distortion of liver tissue. It results from long-term liver injury that leads to impaired hepatic function, portal hypertension, and eventual liver failure. Common causes include chronic infection, toxic exposure, and metabolic disease. Identifying major risk factors is essential for prevention, early detection, and management of liver disease progression.

Rationale:
A. Chronic viral hepatitis infections are a major risk factor for the development of liver cirrhosis. Long-standing infection with hepatitis B or hepatitis C causes persistent inflammation and hepatocyte injury, leading to fibrosis and progressive scarring of liver tissue. Over time, this chronic damage disrupts normal liver architecture and function, significantly increasing the risk of cirrhosis and hepatocellular carcinoma.

B. Infrequent alcohol consumption is not a significant risk factor for cirrhosis. While chronic and heavy alcohol use is a well-established cause of liver damage, occasional or infrequent intake does not typically result in the sustained hepatic injury needed to cause cirrhosis. The risk is strongly associated with long-term, excessive alcohol use rather than sporadic consumption.

C. Regular aerobic exercise is not a risk factor for liver cirrhosis and is generally considered protective for overall health. Physical activity helps improve metabolism, reduce fatty liver risk, and support cardiovascular and hepatic health. It does not contribute to liver inflammation or fibrosis.

D. Consuming a low-fat diet is not associated with an increased risk of cirrhosis. In fact, a balanced or low-fat diet may help reduce the risk of nonalcoholic fatty liver disease, which can otherwise progress to cirrhosis if untreated. Dietary fat intake alone, when appropriate, does not cause chronic liver injury.
