The nurse is preparing to administer 20 units of NPH insulin to a client. Before administering the medication, the nurse should implement which intervention?

Massage the chosen injection site.

Assess the client's urine for the presence of glucose.

Assess the client's understanding of diabetes.

Have a colleague confirm the dosage.

Answer and Explanation

The Correct Answer is D

This intervention is important to ensure accurate dosing and prevent medication errors. Insulin is a high-alert medication, meaning that it has a high potential for causing significant harm to the patient if administered incorrectly. Doublechecking the insulin dosage with a colleague can help prevent errors in dosing, which could lead to hypoglycemia or hyperglycemia in the client. It is also important to confirm the dosage since insulin dosing is based on individualized factors such as the client's blood glucose levels, weight, and overall health status.

Correct Answer is A

Explanation

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.

A. Chlorpromazine B. Fluphenazine C. Haloperidol D. Olanzapine

Correct Answer is D

Explanation

Schizophrenia is a chronic and severe mental illness that requires lifelong treatment. Antipsychotic medications are the cornerstone of treatment for schizophrenia, and they work by blocking dopamine receptors in the brain. These medications are effective in reducing the positive symptoms of schizophrenia, such as hallucinations and delusions, and can also improve negative symptoms like apathy and lack of motivation.

While chlorpromazine, fluphenazine, and haloperidol are all first-generation or "typical" antipsychotic medications, they are less commonly used today due to their side effect profile, which can include movement disorders such as tardive dyskinesia. Olanzapine, on the other hand, is a second-generation or "atypical" antipsychotic medication that is commonly used today due to its efficacy in treating both positive and negative symptoms of schizophrenia, as well as its more favorable side effect profile compared to first-generation antipsychotics.
