Answer and Explanation

The Correct Answer is A

B. Dandelion is not known to directly affect blood clotting or the action of warfarin.
C. Acai berry is a fruit commonly consumed for its potential antioxidant properties and health benefits. There is limited scientific evidence regarding the interaction between acai and warfarin.

Correct Answer is A

Explanation

A. Lithium carbonate is a medication commonly used to treat bipolar disorder. Symptoms of lithium toxicity can include nausea, vomiting, diarrhea, muscle weakness, tremors, and flu-like symptoms. If a client is experiencing these symptoms after taking lithium carbonate, it could indicate lithium toxicity
B. Lithium is a mood stabilizer, and tolerance, in the sense of needing increasing doses to achieve the same effect, is not commonly observed.
C. Suddenly stopping lithium carbonate can lead to withdrawal symptoms, but the symptoms described— nausea, diarrhea, muscle weakness, and tremors—are more indicative of toxicity rather than withdrawal.
D. Tyramine is a compound found in certain foods and beverages, and interactions between tyramine-rich foods and certain medications, such as monoamine oxidase inhibitors (MAOIs), can lead to hypertensive crises. However, lithium carbonate is not known to have interactions with tyramine-rich foods.
