Explanation

Ascites is characterized by significant fluid retention in the peritoneal cavity, driven by hormonal changes that cause the kidneys to retain sodium and water.
The cornerstone of managing ascites is to create a negative sodium balance, which reduces the osmotic pressure that pulls fluid into the abdomen.
Restricting dietary sodium to less than 2,000 mg per day is the primary, first-line dietary intervention to decrease fluid accumulation, alleviate symptoms, and improve the effectiveness of diuretic medications.

Option A: Potassium is not universally restricted. Some diuretics used to treat ascites (like furosemide) cause potassium loss, while others (like spironolactone) are potassium-sparing.
Option B: A universal increase in potassium is not recommended and can be dangerous, especially since spironolactone, a common diuretic for ascites, causes potassium retention.
Option C: This is the opposite of the correct management. Increasing sodium intake would directly worsen fluid retention and increase the volume of ascitic fluid, leading to increased abdominal distension and potential complications.

Clinical Relevance

Nursing practice connection: Use the key finding related to Dietary management of ascites to guide bedside assessment, documentation, and the next nursing action.
Nurses are central to managing ascites through meticulous monitoring of daily weight, abdominal girth, intake/output, and electrolyte levels.
Patient education is a critical nursing responsibility. Teaching patients and their families how to read food labels and make low-sodium choices is essential for long-term management and preventing hospital readmissions.
What if? If the patient develops severe hyponatremia (e.g., serum sodium below 125 mmol/L) while on a sodium-restricted diet, the provider may also order a fluid restriction (e.g., 1 to 1.5 liters per day) to help correct the sodium concentration.

How to Approach the Question

First, identify the key term in the question: 'ascites'. Recall that ascites is the accumulation of excess fluid in the abdominal cavity.
Next, connect the condition to its underlying physiology. Fluid balance in the body is primarily regulated by sodium. The principle is 'water follows sodium'.
To reduce fluid accumulation (ascites), the logical step is to reduce the substance that causes the body to retain water.
Evaluate the options based on this principle. 'Restricted in sodium' directly addresses the goal of reducing fluid retention.
Eliminate 'Increased in sodium' as it is counterproductive and would worsen the condition.
Consider the potassium options. Potassium levels are a concern related to diuretic therapy side effects, not the primary cause of ascites itself. Therefore, sodium management is the primary dietary focus.
