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?

Decreased chloride level

Decreased sodium level

Decreased potassium level

Decreased phosphate level

Answer and Explanation

The Correct Answer is B

Spironolactone is a potassium-sparing diuretic used in the management of ascites associated with liver failure. Its mechanism of action includes blocking the actions of aldosterone, a hormone that promotes sodium retention and potassium excretion in the kidneys. This results in increased urinary sodium excretion and hyponatremia and hyperkalemia.
A. Decreased chloride level is not typically associated with spironolactone use.
C. Spironolactone is a potassium-sparing diuretic, so it leads to an increased potassium level (hyperkalemia)
D. Spironolactone is not associated with decreased phosphate levels.

A. Call the prescribing physician and inform her of the client's serum potassium level results. B. Omit the KCL dose and document it was not given. C. Call the lab to verify the client's results. D. Give the ordered KCL as prescribed.

Correct Answer is A

Explanation

potassium level of 5.2 mEq/L is above the normal range (3.5-5.0 mEq/L), indicating hyperkalemia. Giving potassium chloride (KCL) to a client with hyperkalemia can exacerbate the condition and lead to life- threatening cardiac arrhythmias. It is crucial to notify the physician promptly so that appropriate action can be taken, such as adjusting the dosage of potassium supplementation or discontinuing it altogether.
B. Omitting the KCL dose without consulting the physician is not appropriate as further instructions are needed.
C. Calling the lab to verify the client's results is unnecessary since the nurse already has the laboratory results. The focus should be on informing ensuring client safety.
D. Giving the ordered KCL as prescribed is not appropriate as administering potassium in the presence of hyperkalemia can be dangerous and should be avoided until further guidance is obtained from the physician.
