The client is in a manic phase of bipolar disorder, and is receiving lithium. What will the nurse expect to assess when the client's lithium level is 0.3 mEq/L?

Explanation:

A. Beta blockers are used to manage blood pressure and heart rate but are a different class.

B. Isosorbide is a nitrate, which is used primarily to treat and prevent episodes of angina by relaxing and widening blood vessels.

C. Calcium channel blockers also manage blood pressure and chest pain but act through a different mechanism.

D. Glycoprotein IIb/IIIa receptor antagonists are used to prevent platelet aggregation and are typically used in acute coronary syndrome, not as a long-term treatment for angina.

Explanation:

A. This is because lithium levels can be affected by changes in sodium balance and hydration levels in the body. Excessive sweating can lead to dehydration, which can increase lithium levels and potentially lead to toxicity. Therefore, it is important for clients to be aware of the need to maintain hydration and to communicate with their healthcare provider if there are any significant changes in their fluid balance, such as those caused by excessive sweating.

B. Stopping lithium abruptly, especially when moods are stable, can lead to relapse of bipolar disorder symptoms and is not recommended.

C. Regular monitoring of blood levels of lithium is essential to ensure therapeutic levels and prevent toxicity; therefore, the statement indicating the client no longer needs blood checks is incorrect.

D. Restricting salt intake lowers the sodium levels which can decrease lithium elimination, hence increasing the risk of toxicity.
