If a client taking lithium carbonate (Lithobid) has a level of 3.0 mEq/L, what does this indicate?

A lithium level of 3.0 mEq/L indicates toxicity. Therapeutic levels of lithium typically range from 0.6 to 1.2 mEq/L for most patients. Levels that exceed this therapeutic range can lead to serious side effects and potentially life-threatening complications. When the level reaches or exceeds 2.0 mEq/L, patients are at a significantly increased risk of experiencing serious adverse effects such as tremors, confusion, seizures, and even coma.

Thus, a level of 3.0 mEq/L is well above the therapeutic range, confirming that the client is experiencing lithium toxicity. Monitoring and possibly adjusting the dosage of lithium carbonate would be required to prevent further complications and ensure the safety of the patient.
