Question 1 of 5

The nurse is assessing therapeutic blood levels for a client receiving lithium (Lithobid). The nurse should recognize which of the following levels as toxic for this drug?

Correct Answer: C

Rationale: The correct answer is C: 1.5 mEq/L to 2 mEq/L. Therapeutic blood levels for lithium are typically between 0.6 mEq/L to 1.2 mEq/L, with toxic levels starting around 1.5 mEq/L. Levels above 2 mEq/L can lead to severe toxicity, including symptoms such as confusion, seizures, and even coma.

Choices A, B, and D are within the therapeutic range, while choice C is within the toxic range. It is essential for the nurse to monitor lithium levels closely to prevent toxicity and ensure the client's safety.
