This episode explores the role of mood-stabilizing medications in the treatment of bipolar disorders and cyclothymia. We highlight Lithium carbonate as the prototype agent, discussing its mechanism of action, clinical uses, and importance in managing manic episodes. Nursing considerations take center stage, including electrolyte monitoring (especially sodium), renal excretion, and vigilance with Lithium’s narrow therapeutic range. We’ll also cover anticonvulsant mood stabilizers, recognize the signs of Lithium toxicity, and review key drug interactions that can amplify its effects. Essential knowledge for both clinical practice and exam prep.
