Which neurotransmitter effect occurs with anxiolytic medication?
Facilitates the transmission of glutamate.
Decreases excess dopamine from the presynaptic neuron.
Increases the release of serotonin.
Increases the effectiveness of γ-aminobutyric acid (GABA).
The Correct Answer is D
Choice A rationale
Glutamate is the primary excitatory neurotransmitter in the central nervous system. Its facilitation would increase neuronal activity, which is generally contrary to the desired calming and sedative effects of anxiolytic medications, which typically aim to reduce nervous system overactivity to manage anxiety.
Choice B rationale
Dopamine is a monoamine neurotransmitter involved in reward, motivation, and motor control. While involved in various psychiatric conditions, decreasing excess dopamine is the primary mechanism of action for some antipsychotic medications, not the typical mechanism for anxiolytics, which primarily target anxiety symptoms.
Choice C rationale
Serotonin, a monoamine, modulates mood, sleep, and appetite. Increasing its release or effects is the primary mechanism for some classes of antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), which are also used for anxiety, but is not the defining or typical mechanism of benzodiazepine anxiolytics.
Choice D rationale
γ-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. Anxiolytic drugs, particularly the benzodiazepine class, exert their effect by binding to the GABA_A receptor. This binding enhances GABA's inhibitory effects, leading to hyperpolarization of the neuron, thereby reducing overall neuronal excitability and promoting an anxiolytic (calming) effect.

Correct Answer is B
Explanation
Choice A rationale
Exploring the problem-causing area and establishing an initial treatment contract are central tasks of the orientation phase of the therapeutic relationship. This phase focuses on building rapport, defining the patient's needs and goals, and clarifying the roles and expectations of both the nurse and the patient within the professional boundaries.
Choice B rationale
The termination phase is the final stage of the therapeutic relationship, where the focus shifts to concluding the relationship constructively. A key action is summarizing the goals and objectives achieved, reinforcing the patient's progress, acknowledging the growth and changes made, and preparing the patient for independence, which validates the therapeutic work completed.
Choice C rationale
Taking the patient's personal telephone number constitutes a boundary violation, as it blurs the distinction between a professional and a personal relationship. Maintaining strict professional boundaries is critical throughout all phases of the therapeutic relationship to ensure the focus remains on the patient's therapeutic needs and to prevent potential exploitation.
Choice D rationale
Socializing with the patient, such as going for coffee, is a clear boundary violation that transforms the professional relationship into a personal one. The therapeutic relationship must remain professional and goal-directed, maintaining an objective stance to ensure the patient's needs and safety are always the paramount concern.
Correct Answer is B
Explanation
Choice A rationale
Placing a client on suicide precautions is an intervention (a safety measure) designed to prevent an attempt, not the priority outcome. The outcome is the measurable change in the client's status or behavior that demonstrates goal achievement. While precautions are essential for safety, the ultimate goal is the cessation of the life-threatening behavior itself.
Choice B rationale
Refrain from attempting suicide is the most direct and life-preserving priority outcome for a client with a nursing diagnosis of risk for self-directed violence: suicide. The immediate goal in this high-risk situation is the client's physical safety and survival, which is measurably achieved by the absence of suicidal behavior or gestures. All other goals are secondary to this primary safety objective.
Choice C rationale
Stating absence of feelings of powerlessness is a valuable intermediate or long-term outcome, as powerlessness is a contributing factor to suicidal ideation. However, it addresses the underlying etiology (related to) of the risk, not the life-threatening risk itself. Physical safety must take precedence over emotional or cognitive shifts in the immediate timeframe.
Choice D rationale
Attending a self-help group daily is a therapeutic intervention aimed at long-term coping and recovery, not the immediate priority outcome. While social support and engagement are crucial for preventing recurrence, they do not represent the primary, measurable, and immediate objective of protecting the client's life from imminent self-harm.
