The client with hyperthyroidism has a prescription for lithium carbonate (Lithobid). The client should be taught to take the medication: A. Two times per day B. With milk or meals C. With an antiemetic D. For the treatment of psychosis

Lithium carbonate (Lithobid) is a medication primarily used to treat bipolar disorder. It is also used for the treatment of major depressive disorder and occasionally used for hyperthyroidism. It is essential to understand the purpose of the medication before moving on to the administration aspect.

Now that we have a better understanding of lithium carbonate, let's look at the options given and rule out the ones that are not correct: Option A: Two times per day - The frequency of lithium carbonate intake depends on the patient's condition and doctor's prescription, so we cannot be sure about this option. Option C: With an antiemetic - There is no general instruction to take lithium carbonate with an antiemetic. This is not the most appropriate answer. Option D: For the treatment of psychosis - Although lithium carbonate can be used in some cases of psychosis, it is not the primary indication for the medication. This option is not directly related to the administration of lithium carbonate, making it an incorrect choice.

Having ruled out options A, C, and D, we are left with the correct option: Option B: With milk or meals - Taking lithium carbonate with milk or meals can help reduce stomach upset caused by the medication. This is a proper administration for taking the medication, making option B the correct answer.
