A nurse is caring for a client who has opioid toxicity and has a respiratory rate of 6/min. Which of the following medications should the nurse plan to administer?

Choice A reason: Initial substance use in adulthood is less likely to lead to addiction compared to adolescence, as the adult brain’s prefrontal cortex is more developed, improving impulse control. Addiction risk is lower because neuroplasticity decreases, reducing the brain’s vulnerability to substance-induced reward pathway alterations.

Choice B reason: Early substance exposure during adolescence increases addiction risk, as the developing brain’s prefrontal cortex and reward systems (e.g., dopamine pathways) are highly plastic. Substances like alcohol or drugs can rewire neural circuits, enhancing dependence by altering dopamine release and receptor sensitivity in the nucleus accumbens, a key addiction pathway.

Choice C reason: Pre-existing cognitive deficits may increase vulnerability to addiction by impairing decision-making and impulse control, linked to prefrontal cortex dysfunction. However, this is less significant than early substance exposure, which directly reshapes developing neural pathways, making it a secondary factor in addiction risk compared to developmental exposure.

Choice D reason: Medical insurance availability facilitates addiction treatment but does not directly increase addiction risk. It affects access to care, not the neurobiological mechanisms of addiction, such as dopamine dysregulation in the reward system, making it irrelevant to the factors that predispose individuals to substance dependence.

Choice A reason: Asking “why” the client feels anxious may seem judgmental and implies the client should know the cause, potentially increasing anxiety. It does not foster therapeutic communication or gather critical information about the client’s condition, which is driven by neurochemical imbalances like elevated cortisol or serotonin dysregulation in anxiety disorders.

Choice B reason: Asking about talking to parents is inappropriate for a young adult, as it assumes dependency and dismisses autonomy. It fails to address the client’s immediate anxiety and concentration issues, which may stem from neurobiological factors like amygdala hyperactivity, requiring a more empathetic and relevant response.

Choice C reason: Stating “It sounds like you’re having a difficult time” validates the client’s feelings, fostering therapeutic communication. This empathetic response builds trust, encouraging the client to share more about their anxiety and concentration issues, which may involve dysregulation of neurotransmitters like GABA or norepinephrine, facilitating further assessment and support.

Choice D reason: Asking about the duration of symptoms is useful for assessment but does not immediately validate the client’s emotional experience. Anxiety and concentration issues may involve heightened amygdala activity, but a therapeutic response prioritizing empathy is more effective initially to establish rapport before delving into symptom history.
