Question 1 of 5
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?
Correct Answer: D
Rationale: The correct answer is D: Creatinine 2.1 mg/dL. Elevated creatinine levels may indicate impaired kidney function, increasing the risk of lithium toxicity as lithium is primarily excreted by the kidneys. Holding the medication and notifying the healthcare provider is crucial to prevent potential lithium toxicity.
A: Potassium level within normal range, not directly related to lithium toxicity.
B: Sodium level within normal range, not directly related to lithium toxicity.
C: Calcium level within normal range, not directly related to lithium toxicity.
Summary: Elevated creatinine level is concerning for impaired kidney function and potential lithium toxicity, while the other choices are within normal limits and not directly related to lithium toxicity.
