A nurse is providing discharge teaching to a client who has bipolar disorder and will be discharged with a prescription for lithium. The nurse could teach the client which of the following factors puts her at risk for lithium toxicity?
A client runs 4 miles outdoors every afternoon.
The client eats 2 to 3 gm of sodium-containing foods daily.
The client drinks 2 liters of liquids daily.
The client eats foods high in tyramine.
The Correct Answer is A
A. Lithium is excreted through the kidneys, and dehydration and sodium depletion increase the risk of lithium toxicity. A client who runs 4 miles outdoors every afternoon is at risk of excessive sweating and fluid loss, which can lead to dehydration and sodium depletion. This reduces lithium excretion, leading to toxic levels in the blood.
B. A normal sodium intake helps maintain lithium balance. A low sodium intake increases lithium retention, but 2-3 grams/day is within the normal recommended range.
C. Adequate hydration helps prevent lithium toxicity. Clients on lithium should drink 2–3 liters of fluid daily to promote kidney function and lithium excretion.
D. Tyramine-rich foods (e.g., aged cheese, cured meats) are a concern for clients on monoamine oxidase inhibitors (MAOIs), not lithium. Tyramine does not affect lithium levels.

Correct Answer is A
Explanation
A. Plan the client's schedule to allow time for rituals.
Explanation:
For individuals with obsessive-compulsive disorder (OCD), engaging in rituals or repetitive behaviors can be a way to manage anxiety. Allowing time for these rituals within the client's schedule, while gently working towards reducing their impact, is a part of a gradual therapeutic approach known as Exposure and Response Prevention (ERP). ERP aims to help the client gradually face their anxiety triggers while refraining from engaging in compulsions.
Why the other choices are incorrect:
B. Confront the client about the senseless nature of the repetitive behaviors.
Confrontation can increase the client's anxiety and resistance to treatment. Instead, the nurse should approach the client with understanding and gradually work on strategies to reduce the compulsive behaviors.
C. Isolate the client for a period of time.
Isolating the client is not a therapeutic approach for managing OCD. It can lead to increased distress and negatively impact their mental health. Inclusion and support are more effective strategies.
D. Set strict limits on the behaviors so that the client can conform to the unit rules and schedules.
Setting strict limits may escalate the client's anxiety and could be counterproductive. It's important to work collaboratively with the client and apply evidence-based approaches like ERP to manage their symptoms effectively.
Correct Answer is ["1.5"]
Explanation
To calculate the number of clozapine 200 mg tablets needed to administer a total of 300 mg, divide the total dose by the dose per tablet:
300 mg / 200 mg = 1.5 tablets
Since you cannot administer half of a tablet, you would need to administer 2 tablets to achieve a total of 300 mg.
So, the nurse should administer 2 tablets of clozapine 200 mg each to achieve a total dose of 300 mg.
