A nurse is reviewing the medical record of a client and identifies a serum potassium 6.8 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect to administer?
Lactulose
Acetylcysteine
Sodium polystyrene (Kayexalate)
Triamterene
The Correct Answer is C
A. Lactulose: Lactulose is used to treat hepatic encephalopathy by reducing ammonia levels, not for hyperkalemia.
B. Acetylcysteine: Acetylcysteine is used for acetaminophen overdose or as a mucolytic agent, not for hyperkalemia.
C. Sodium polystyrene (Kayexalate): Kayexalate is used to treat hyperkalemia by exchanging sodium for potassium in the intestines, promoting the elimination of potassium through the stool. This is the correct treatment for a potassium level of 6.8 mEq/L, which is dangerously high.
D. Triamterene: Triamterene is a potassium-sparing diuretic and would worsen hyperkalemia, not treat it.

Correct Answer is B
Explanation
A. Increased bowel sounds: Hypokalemia typically causes decreased bowel activity, leading to constipation or paralytic ileus, rather than increased bowel sounds.
B. Reports of fatigue: Fatigue is a hallmark symptom of hypokalemia due to impaired cellular and muscle function.
C. Positive Trousseau's sign: This is associated with hypocalcemia, not hypokalemia.
D. Reports of numbness in the feet: This is more commonly linked with neuropathy or hypocalcemia, not hypokalemia.
Correct Answer is C
Explanation
A. Have the laboratory draw a blood sample for an erythrocyte sedimentation rate (ESR): ESR measures inflammation and is unrelated to hyperkalemia.
B. Restrict fluid intake: Fluid restriction is not appropriate for hyperkalemia unless specifically related to fluid overload or renal failure.
C. Obtain a 12-lead ECG: Hyperkalemia can cause life-threatening cardiac dysrhythmias such as peaked T waves, widened QRS complexes, or asystole. ECG monitoring is essential.
D. Administer potassium gluconate 40 mEq orally: This would worsen hyperkalemia and is contraindicated.
