Question 4 of 5
Which of the following best describes a current working hypothesis about the molecular mechanism of action of lithium?
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.

Which of the following adverse effects is most likely to occur during the first days of lithium therapy?

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.
