A client is being prescribed a central nervous system stimulant. Which will haw lowest risk of abuse and dependence?

Dextroamphetamine

Dexmethylphenidate

Dextroamphetamine and amphetamine

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 A

Explanation

A. An increase in serum lactate – This is a critical laboratory value that can indicate lactic acidosis, a serious side effect associated with metformin, especially in older adults or those with renal impairment. An increase in serum lactate necessitates discontinuation of the medication.

B. A decrease in hemoglobin and hematocrit – While this change may indicate anemia, it is not directly associated with the need to discontinue metformin. Further evaluation of the cause of anemia would be necessary.

C. An increase in white blood cells – This could indicate an infection or inflammatory process but does not specifically necessitate the discontinuation of metformin.

D. A decrease in potassium accompanied by an increase in sodium – While electrolyte imbalances should be monitored, this change does not directly indicate that metformin should be discontinued.

A. Intravenously B. Orally C. With a TB syringe D. Dilution strength of U-10

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.
