A. Client with serum phosphorus level of 4.5 mg/dL. B. Client with serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes. C. Client with serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping. D. Client with serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water.

Correct Answer is B

Explanation

A. Client with serum phosphorus level of 4.5 mg/dL: This is within the normal range for phosphorus (2.5-4.5 mg/dL), and the client does not require immediate assessment.

B. Client with serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes: This is the correct answer. A magnesium level of 1.1 mEq/L is below the normal range (1.5-2.5 mEq/L), and symptoms like tremors and hyperactive reflexes indicate hypomagnesemia, which can lead to serious complications such as arrhythmias.

C. Client with serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping: A potassium level of 5.0 mEq/L is within the normal range (3.5-5.0 mEq/L), so this client does not need immediate intervention.

D. Client with serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water: A sodium level of 145 mEq/L is at the upper end of normal (135-145 mEq/L), and the symptoms are likely due to dehydration or a normal response.
