A client is started on levothyroxine for the treatment of hypothyroidism. During client teaching, the nurse indicates that the dosage may be increased how often until symptoms are relieved?

A. Weekly – This frequency is too frequent for dosage adjustments of levothyroxine. Adjustments are generally made less frequently to allow for the medication to reach therapeutic levels.

B. Monthly – While some adjustments may be made on a monthly basis, this is not the typical recommendation.

C. Every 3 to 5 days – This is also too frequent for dosage adjustments as it may not allow enough time to assess the effects of the current dose.

D. Every 4 to 6 weeks – This is the correct recommendation for adjusting levothyroxine dosages. After starting therapy or adjusting the dose, it is advised to wait 4 to 6 weeks before evaluating thyroid function tests and making any further adjustments to the dosage, as it takes time for the medication to take effect.

Metformin is an oral medication used to lower blood sugar levels in clients with type 2 diabetes. It works by decreasing the production and absorption of glucose in the liver and intestines, respectively. However, metformin is contraindicated in clients with severe infections, as the drug can increase the risk of developing lactic acidosis, a rare but serious complication characterized by the buildup of lactic acid in the bloodstream.

During a severe infection, the body may experience a state of inflammation and stress, which can cause metabolic changes that increase the risk of developing lactic acidosis. Therefore, metformin should be temporarily discontinued in clients with severe infections and resumed only after the infection has been successfully treated and resolved.

In the meantime, the client's diabetic regimen may need to be adjusted to maintain appropriate blood sugar levels. This may include the use of alternative medications such as insulin, which can be used to control blood sugar levels during times of illness or infection. The healthcare provider will determine the appropriate management plan based on the individual client's needs and medical history.
