Question 1 of 5
A nurse reviews the laboratory report for a client who is receiving lithium three times daily PO. The client's current blood lithium level is 1.8 mEq/L. The nurse identifies that this lab value indicates which of the following?
Correct Answer: C
Rationale: The correct answer is C: The lithium level is at the toxic level. A blood lithium level of 1.8 mEq/L is above the therapeutic range (0.6-1.2 mEq/L) and indicates toxicity.
Toxicity symptoms can range from mild (1.5-2.0 mEq/L) to severe (>2.0 mEq/L) and may include gastrointestinal symptoms, tremors, confusion, and even seizures. It is crucial to monitor lithium levels closely to prevent toxicity.
Summary:
A: Incorrect - The lithium level is above the therapeutic range.
B: Incorrect - The lithium level is not below the therapeutic treatment level.
D: Incorrect - The blood lithium level falls within the toxic range, not the maintenance treatment level.
