The nurse is caring for a client who has been diagnosed with schizophrenia. The nurse understands that the client's condition is thought to be most likely related to an increased level of activity of what neurotransmitter?

Dopamine

Adenosine

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

Regular insulin is usually administered subcutaneously, and the TB syringe is commonly used for this purpose in pediatric patients due to its small size and ability to accurately measure small doses. The nurse will need to ensure that the proper injection technique is used to ensure the safety and effectiveness of the insulin administration.

A. Weekly B. Monthly C. Every 3 to 5 days D. Every 4 to 6 weeks

Correct Answer is D

Explanation

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.
