A nurse cares for a client with a serum potassium of 5.4 mEq/L. The nurse should anticipate a prescription order for what medication?

Kayexalate (sodium polystyrene)

Potassium chloride

Sodium bicarbonate

Aldactone (spironolactone)

Answer and Explanation

The Correct Answer is A

A. Kayexalate (sodium polystyrene): This is the correct choice. Kayexalate is used to treat hyperkalemia (high serum potassium levels) by facilitating the removal of excess potassium from the body through the gastrointestinal tract.
B. Potassium chloride: This is used to treat hypokalemia (low potassium levels), not hyperkalemia.
C. Sodium bicarbonate: This can be used to correct metabolic acidosis and may indirectly help with potassium levels, but it is not the primary treatment for hyperkalemia.
D. Aldactone (spironolactone): This is a potassium-sparing diuretic that can increase potassium levels, which would be contraindicated in the case of hyperkalemia.

Correct Answer is D

Explanation

A. Discard the container of formula every 12 hours: While this is important for preventing contamination, it does not directly address the risk of aspiration.
B. Irrigate the tube with sterile water before administering medications: This helps maintain tube patency and prevent clogging but does not significantly impact the prevention of aspiration.
C. Measure & record the residual volume after each feeding: Monitoring residuals is crucial for assessing gastric emptying and preventing overfeeding but does not directly prevent aspiration.
D. Keep head of bed elevated 30 degrees: This is the correct choice. Elevating the head of the bed reduces the risk of aspiration by ensuring that gravity helps keep the feeding in the stomach and minimizes the risk of reflux into the esophagus.

A. Potassium 2.9 mEq/L B. Sodium 125 mEq/L C. Potassium 4.6 mEq/L D. Sodium 139 mEq/L E. Magnesium 2.1 mEq/L

Correct Answer is ["A","B"]

Explanation

A. Potassium 2.9 mEq/L: This indicates hypokalemia, which is a common electrolyte imbalance associated with diuretic therapy, particularly with loop diuretics.
B. Sodium 125 mEq/L: This indicates hyponatremia, another possible electrolyte imbalance resulting from diuretic use.
C. Potassium 4.6 mEq/L: This is within the normal range and does not indicate an imbalance.
D. Sodium 139 mEq/L: This is within the normal range and does not indicate an imbalance.
E. Magnesium 2.1 mEq/L: This is within the normal range and does not indicate an imbalance.
