  Toxicity occurs at doses close to therapeutic levels, due to lithiums narrow therapeutic index.  Therefore close monitoring is necessary.  When treatment begins the patient must have his serum levels monitored every one to three days, and every two to three months after that (Adams, 2018).  If toxicity occurs,  the patient will be treated with hemodialysis and supportive care.  If taken during pregnancy potential hazard to the fetus may occur.  Data links lithium births to an increase in cardiac and other abnormalities, such as Ebstein’s anomaly.(Allen, 2016)After reviewing the above information I enter John’s room to discuss the following.  Hello John, I would like to discuss your diagnosis and medications with you and make sure you don’t leave here today with any questions.

  I understand you have been experiencing some changes in your mood, as well as your activity and energy levels.  The physician has diagnosed you with bipolar disorder, and we will be sending you home today with a prescription of Eskalith.  This is a very effective mood stabilizer that has been used for over 50 years.  We are going to ask you to come in every few days to test the amount of lithium in your blood, this is just so we can adjust the dosage to be just right for you, and once your lithium level is stable these blood tests will become less frequent.  If the dosage is too low it will not be effective, and if it is too high it can be harmful.  It is very important for you and your family to watch for early toxic symptoms and contact us immediately if you start experiencing diarrhea, vomiting, tremors, drowsiness, muscular weakness or if you feel like you are losing control of your body movements.  I will suggest you refrain from driving or operating machinery during your adjustment period.
