Answer and Explanation

The Correct Answer is A

Schizophrenia is believed to be related to an overactivity of the dopamine system in certain areas of the brain.

This is referred to as the dopamine hypothesis of schizophrenia.

Explanation

A. Metformin will be given more frequently to decrease blood sugar. B. Metformin will result in better regulation of blood sugar. C. Metformin is contraindicated in the presence of an infection. D. Metformin will allow the client to decrease the absorption of glucose

Correct Answer is C

Explanation

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.
