A patient has been admitted and the nurse suspect lithium toxicity. What symptoms should be suspected with a patient who has to
shortness of breath, gastrointestinal distress, chronic cough
weakness, nausea, diarrhea
ECG changes, chest pain, dizziness
gastrointestinal distress, thirst, nystagmus
The Correct Answer is B
Rationale:
A. Shortness of breath and chronic cough are not typical early signs of lithium toxicity; these suggest possible respiratory or cardiac issues unrelated to lithium.
B. Early signs of lithium toxicity include gastrointestinal upset (nausea, diarrhea) and neuromuscular effects such as weakness.
C. ECG changes and chest pain can occur with severe toxicity, but they are not the most common initial symptoms.
D. Thirst may be a side effect of lithium due to nephrogenic diabetes insipidus, and nystagmus can occur in severe neurotoxicity, but these are not the classic early warning signs.
