Final Answer:
To avoid toxicity with lithium, nursing actions include monitoring serum lithium levels regularly, educating the patient about maintaining consistent sodium intake and hydration, assessing for signs of lithium toxicity, such as tremors or confusion, and advising the patient to avoid significant changes in diet, especially sodium intake.
Step-by-step explanation:
Lithium is commonly prescribed for mood disorders, and maintaining therapeutic levels while avoiding toxicity is crucial. Regular monitoring of serum lithium levels ensures that the patient is within the therapeutic range. Educating patients on the importance of consistent sodium and fluid intake helps stabilize lithium levels. Nurses should assess for signs of lithium toxicity, including gastrointestinal distress, tremors, and neurologic symptoms. Additionally, advising patients to maintain a stable diet and fluid intake helps prevent fluctuations in lithium levels.
