Correct Answer: A

Rationale: The correct answer is A. Increased synthesis of adenylyl cyclase. One of the leading hypotheses about the molecular mechanism of action of lithium is its ability to increase the synthesis of adenylyl cyclase. Adenylyl cyclase is an enzyme involved in the production of cyclic adenosine monophosphate (cAMP), which plays a role in cellular signaling pathways. By increasing the synthesis of adenylyl cyclase, lithium may help to regulate intracellular signaling and neurotransmitter release, contributing to its mood-stabilizing effects in bipolar disorder.

Correct Answer: C

Rationale: Insomnia is a common early adverse effect of lithium therapy due to its impact on sleep patterns. Patients may experience difficulty falling asleep or staying asleep during the initial days of treatment. This side effect typically resolves as the body adjusts to the medication. Constipation, weight loss, hypertension, and edema are less commonly associated with lithium therapy in the early stages.

Correct Answer: C

Rationale: Bupropion is a medication that is commonly used to treat depression, ADHD, and smoking cessation. Given the woman's symptoms of feeling fearful, helpless, and worried, as well as her difficulty organizing thoughts and smoking habit, bupropion would be a suitable choice as it can address both depressive and attention deficit disorders, as well as aid in smoking cessation.
