Atomoxetme

Answer and Explanation

The Correct Answer is D

Atomoxetine is a non-stimulant medication that is used to treat attentiondeficit/hyperactivity disorder (ADHD). Unlike central nervous system (CNS) stimulants such as dextroamphetamine, dexmethylphenidate, and dextroamphetamine/amphetamine, atomoxetine does not have a high risk of abuse or dependence.

CNS stimulants like dextroamphetamine, dexmethylphenidate, and dextroamphetamine/amphetamine can be effective in treating ADHD symptoms, but they can also be abused and lead to dependence. These medications work by increasing levels of dopamine and norepinephrine in the brain, which can improve focus and attention. However, they also have the potential to be misused, particularly by individuals seeking a "high" or increased alertness.

In contrast, atomoxetine works by selectively inhibiting the reuptake of norepinephrine in the brain. This mechanism of action does not produce the same effects on dopamine levels as CNS stimulants, and it is not associated with a high risk of abuse or dependence. However, it may take several weeks for the full therapeutic effects of atomoxetine to be seen, and it may not be as effective as CNS stimulants for some individuals with ADHD.

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.

Correct Answer is D

Explanation

would rule out a diagnosis of adrenal insufficiency after a short plasma corticotropin (ACTH) stimulation test. In this test, a synthetic form of ACTH is given to stimulate the adrenal glands to produce cortisol. If the adrenal glands are functioning normally, they should produce an increased amount of cortisol in response to the ACTH. Therefore, if the client has elevated cortisol levels after the test, it would indicate that their adrenal glands are functioning properly and ruling out adrenal insufficiency.
