A patient diagnosed with bipolar disorder is prescribed lithium carbonate. Which laboratory result should prompt the nurse to hold the medication and notify the healthcare provider?

Potassium 4.2 mEq/L

Sodium 136 mEq/L

Calcium 9.0 mg/dL

Creatinine 2.1 mg/dL

Answer and Explanation

The Correct Answer is D

A. Potassium 4.2 mEq/L is within the normal range (3.5–5.0 mEq/L).

B. Sodium 136 mEq/L is slightly low but does not warrant withholding lithium. However, sodium levels should be monitored regularly as low sodium increases the risk of lithium toxicity.

C. A calcium level of 9.0 mg/dL is within the normal range (8.5–10.2 mg/dL).

D. An elevated creatinine level (2.1 mg/dL) indicates possible renal dysfunction, which is a concern for lithium use. Lithium is excreted by the kidneys, and impaired renal function increases the risk of lithium toxicity.
