After taking orlistat for one week, a female client tells the home health nurse that she is experiencing increasingly frequent faty stools and flatus. Which action should the nurse take?

Lithium carbonate is a mood stabilizer commonly used to treat bipolar disorder. However, it has a narrow therapeutic index and requires careful monitoring of serum levels to avoid toxicity. One of the major concerns with lithium therapy is the potential for drug interactions and toxicity. NSAIDs such as ibuprofen and naproxen can increase lithium levels by reducing its excretion and can lead to lithium toxicity. Therefore, it is essential to instruct the client to eliminate the use of NSAIDs while taking lithium.

Option b) Avoid consuming all foods that contain iodine is incorrect because iodine is not contraindicated with lithium. However, excessive iodine intake can interfere with thyroid function, which can exacerbate mood instability.

Option c) Notify healthcare provider prior to dental procedures is not specific to lithium therapy and is a general precaution that patients with bipolar disorder should follow before any medical or dental procedures.

Option d) Monitor blood glucose levels daily is also not directly related to lithium therapy. While lithium can cause diabetes insipidus, which can lead to excessive thirst and urination, it does not typically affect blood glucose levels.

Probenecid is a uricosuric drug that works by inhibiting the reabsorption of uric acid in the kidneys and promotes its excretion in the urine. This drug is used to treat gout and hyperuricemia (high levels of uric acid in the blood). Therefore, the nurse should explain to the client that the purpose of probenecid is to promote the excretion of uric acid in the urine and lower the levels of uric acid in the blood, which can help prevent gout attacks and kidney stones.

Options a, b, and d are incorrect as they do not accurately describe the mechanism of action or purpose of probenecid.
