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

Answer and Explanation

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 A

Explanation

A. Cardiac dysrhythmias: Hypokalemia impairs cardiac muscle function, potentially leading to arrhythmias such as ventricular tachycardia or premature ventricular contractions.

B. Hypoglycemia: Potassium does not directly cause hypoglycemia; its imbalance more commonly affects cardiac and neuromuscular function.

C. Hyperreflexia: Hypokalemia usually causes muscle weakness and diminished reflexes (hyporeflexia), not hyperreflexia.

D. Increased appetite: Hypokalemia does not typically affect appetite.

A. Increased appetite B. Hyporeflexia C. Constipation D. Headache

Correct Answer is D

Explanation

A. Increased appetite: Hyponatremia does not typically cause increased appetite.

B. Hyporeflexia: Severe hyponatremia may lead to neurological symptoms, but reflex changes are less common.

C. Constipation: This is unrelated to sodium levels.

D. Headache: Hyponatremia causes cellular swelling, including in the brain, leading to headache, nausea, and neurological symptoms.
