A nurse is monitoring a client who has just had a thoracentesis to remove pleural fluid. Which of the following clinical manifestations should indicate to the nurse the client is experiencing a complication and the provider should be notified immediately?

Choice A reason: Cushing's disease often causes hypokalemia, or low potassium levels, due to increased aldosterone production. Therefore, limiting potassium-rich foods is not advisable; rather, patients may need to increase their potassium intake to maintain electrolyte balance.

Choice B reason: The correct answer is b because Cushing's disease leads to sodium retention and fluid retention, causing hypertension and edema. Decreasing sodium intake helps manage these symptoms by reducing fluid retention and controlling blood pressure.

Choice C reason: Increasing calorie intake is not recommended for clients with Cushing's disease. The condition often leads to weight gain and increased adipose tissue, so a balanced diet with controlled calorie intake is more appropriate.

Choice D reason: Consuming more calories from carbohydrates than protein is not a specific recommendation for Cushing's disease. A balanced diet with adequate protein is important for maintaining muscle mass and supporting overall health, especially since Cushing's disease can cause muscle weakness and loss of muscle mass.

Choice A reason: Lactulose is a laxative used to treat constipation and hepatic encephalopathy by reducing blood ammonia levels, but it is not effective in lowering serum potassium levels. Therefore, it would not be the appropriate medication for treating hyperkalemia.

Choice B reason: Triamterene is a potassium-sparing diuretic, which means it helps the body retain potassium. Administering Triamterene in a client with high potassium levels (hyperkalemia) would exacerbate the condition rather than improve it. Hence, it is not a suitable choice for this scenario.

Choice C reason: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by binding to potassium in the intestines and facilitating its removal from the body through feces. It effectively reduces serum potassium levels, making it the appropriate medication for a client with hyperkalemia.

Choice D reason: Acetylcysteine is used primarily as a mucolytic agent to break down mucus in the airways or as an antidote for acetaminophen (paracetamol) overdose. It does not have any effect on serum potassium levels and is not suitable for treating hyperkalemia.
