A patient diagnosed with bipolar disorder is in the maintenance phase of treatment. The patient asks, "Do I have to keep taking this lithium even though my mood is stable now?" Select the nurse's appropriate response.

"It's unusual that the health care provider hasn't already stopped your medication."

"Most patients take medication for approximately 6 months after discharge."

"Taking the medication every day helps reduce the risk of a relapse."

"You will be able to stop the medication in about 1 month."
