Final answer:
Lithium is the drug that is commonly prescribed to ease the symptoms of bipolar disorder and is considered a mood stabilizer. So the correct answer is option (A).
Step-by-step explanation:
Regarding the question of which drug would likely be prescribed to ease the symptoms of bipolar disorder, lithium is a common choice. Lithium is classified as a mood stabilizer and is often used to treat the manic and depressive episodes associated with bipolar disorder. It helps to stabilize mood swings and reduce the severity and frequency of these episodes.
Drugs such as Prozac (an antidepressant), Xanax (an anxiolytic), and Adderall (a stimulant) may be used to treat other psychiatric conditions, but they are not typically first-line treatments for bipolar disorder's core symptoms. Prozac may sometimes be used alongside mood stabilizers to manage depressive episodes in bipolar disorder, while Xanax could be prescribed for acute anxiety symptoms. Adderall is not typically used in the treatment of bipolar disorder, as it may exacerbate manic episodes.
