Practice Question
A home health nurse has a patient who is taking lithium. What should be included in the teaching plan?
Answer Choices:
Correct Answer:
Have her drug blood level checked every month.
Rationale:
🔷 Lithium has a narrow therapeutic index, meaning blood levels must be monitored regularly to prevent toxicity.
🔷 Monthly serum lithium checks are standard during maintenance therapy to ensure the drug remains within the therapeutic range (0.6–1.2 mEq/L).
🔷 Symptoms of toxicity include tremors, confusion, and GI upset, and can occur quickly if levels rise.
🔷 Routine monitoring also helps evaluate renal function, as lithium is excreted via the kidneys.
