Muscle weakness.
Constipation.
Urinary retention.
Hyperactivity.
The Correct Answer is A
Choice A rationale:
Muscle weakness is a manifestation of mild lithium toxicity. Lithium toxicity can occur at therapeutic levels, so clients should be monitored for adverse effects.
Choice B rationale:
Constipation is not typically associated with lithium toxicity. Diarrhea, not constipation, is a symptom of lithium toxicity.
Choice C rationale:
Urinary retention is not a typical symptom of lithium toxicity. Increased urination and thirst are common side effects of lithium.
Choice D rationale:
Hyperactivity is not a typical symptom of lithium toxicity. Lithium is used to manage bipolar disorder and can help reduce hyperactivity.
