A nurse is reviewing the laboratory results of a client who has liver failure with ascites and is receiving spironolactone. Which of the following findings should the nurse expect?

The correct answer is B: Decreased sodium level. Spironolactone is a potassium-sparing diuretic commonly used in liver failure with ascites to prevent hypokalemia. It works by blocking aldosterone receptors, leading to retention of potassium and excretion of sodium. In liver failure, sodium retention is a common issue due to decreased production of albumin and impaired liver function, leading to ascites. Therefore, the nurse should expect a decreased sodium level as spironolactone helps in excreting sodium to manage fluid overload.
Incorrect choices:
A: Decreased chloride level - Spironolactone does not directly affect chloride levels.
C: Decreased potassium level - Spironolactone helps in retaining potassium.
D: Decreased phosphate level - Spironolactone does not directly impact phosphate levels in this context.
