Correct Answer is B

Explanation

A. Meperidine is contraindicated with monoamine oxidase inhibitors (MAOIs) and can lead to serotonin syndrome rather than being an antidote for hypertensive crisis.

B. Calcium channel blockers, such as nifedipine, are commonly used as antidotes for hypertensive crisis associated with MAOI use.

C. Carbamazepine is not indicated for the treatment of hypertensive crisis associated with MAOI use.

D. Dextromethorphan is contraindicated with MAOIs due to the risk of serotonin syndrome.

A. “I need to call my physician if I excessively sweat during exercise," B. “I can stop taking my lithium when my moods are stable." C. I don't need to have my blood checked anymore after I leave the hospital." D. "I need to restrict my intake of salt while I am taking lithium."

Correct Answer is A

Explanation

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.
