This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Monitor lithium therapy
Prompt focus: A nurse is caring for a patient who takes lithium for bipolar disorder. The patient reports coarse hand tremors, vomiting, diarrhea, and confusion. The lithium level is 2.1 mEq per L. Which action should the nurse take?
Why the correct answer works
Hold the lithium and notify the provider immediately
A lithium level of 2.1 mEq per L with these symptoms indicates toxicity, so the nurse holds the drug and notifies the provider.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
The therapeutic lithium range is roughly 0.6 to 1.2 mEq per L. A level of 2.1 mEq per L with vomiting, diarrhea, coarse tremor, and confusion indicates lithium toxicity.
Simple analogy
Think of monitor lithium therapy like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
