What is the therapeutic serum level of lithium, and what should the nurse teach?
Answer and explanation
Correct answer: C. 0.6 to 1.2 mEq/L, and keep fluid and salt intake steady
- Step 1: The range is narrow, and toxicity occurs above 1.5. Step 2. Low sodium or dehydration raises lithium levels. Answer: 0.6 to 1.2 mEq/L with steady fluid and salt intake. Why not the others: the other values are incorrect and unsafe.
