Norepinephrine

Acetylcholine

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. Antipsychotic medications, which are the primary treatment for schizophrenia, work by blocking dopamine receptors, thereby decreasing the activity of the dopamine system. This is referred to as the dopamine hypothesis of schizophrenia.

Correct Answer is C

Explanation

Lisdexamfetamine is a prodrug of dextroamphetamine, which means that it is converted into dextroamphetamine in the body. It is a central nervous system (CNS) stimulant medication used to treat attention deficit hyperactivity disorder (ADHD). Lisdexamfetamine has a lower risk of abuse and dependence compared to other amphetamines, such as methamphetamine, dextroamphetamine, and dextroamphetamine and amphetamine combination products.

Lisdexamfetamine is a long-acting medication that is taken once daily, and it has a slower onset of action compared to other amphetamines. This slower onset of action may make it less attractive for abuse or misuse, as individuals seeking immediate effects may be less likely to use lisdexamfetamine.

However, it is important to note that all amphetamines have the potential for abuse and dependence, and they should only be used under the close supervision of a healthcare provider. Individuals taking amphetamines for ADHD should be closely monitored for signs of misuse, and the medication should be discontinued if misuse or abuse is suspected.

A. Static levels of serum cortisol B. Blood glucose <70 mg/dL (3.80 mmol/L) C. Decreased serum sodium levels D. Elevated cortisol levels

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.
