A nurse in a mental health facility is collecting data from a client who is taking lithium. Which of the following findings should the nurse report to the provider as an indication of lithium toxicity?

A. Slurred speech can be a symptom of lithium toxicity. As lithium levels rise in the blood, it can affect neurological function, leading to symptoms such as confusion, drowsiness, tremors, and slurred speech. B. Stooped posture is not typically associated with lithium toxicity. It is more commonly associated with musculoskeletal issues or neurological disorders rather than lithium toxicity. C. Elevated blood pressure is not a typical symptom of lithium toxicity. Lithium can actually have a protective effect on blood pressure, and hypertension is not commonly associated with lithium toxicity. D. Dry cough is not a symptom of lithium toxicity. It is more commonly associated with respiratory conditions or medication side effects rather than lithium toxicity.
