The nurse is continuing to care for the client. The nurse is providing teaching about lithium to the client and the client's adult child. Select the 3 statements the nurse should include.

A. "This medication can cause nausea and drowsiness.": Gastrointestinal upset, including nausea, and central nervous system effects such as drowsiness or mild tremor are common early adverse effects of lithium. Clients should be monitored for symptom severity and reassured that these effects often diminish over time. B. "You will be placed on a low-sodium diet while taking this medication": Lithium excretion is highly dependent on sodium levels; however, clients are advised to maintain a consistent, adequate sodium intake rather than restricting sodium. A low-sodium diet can increase lithium retention and risk toxicity. C. "It will take at least a week before this medication reaches a therapeutic level.": Lithium requires several days to reach a steady-state concentration in the blood. Clients and caregivers should understand that therapeutic effects on mood stabilization may not be immediate, and monitoring serum levels is necessary. D. "This medication can cause weight gain.": Weight gain is a recognized long-term adverse effect of lithium therapy, likely related to metabolic changes and fluid retention. Clients should be counseled on healthy diet and activity to help mitigate this effect. E. "Blurred vision is an expected adverse effect of this medication": Blurred vision is not an expected or common side effect of lithium. If it occurs, it may indicate toxicity or another ophthalmologic issue, requiring immediate evaluation.
