A nurse is reinforcing education to a group of clients about the process of neurotransmission. Which of the following statements about neurotransmission should the nurse make?
"Neurotransmitters are chemical components that allow neurons to store energy for future use."
"Neurotransmitters are activated by the enzyme transferase."
"Neurotransmitters function by inhibiting the production of glucose."
"Neurotransmitters are found throughout the body."
The Correct Answer is D
A. Neurotransmitters are chemical components that allow neurons to store energy for future use. Neurotransmitters do not store energy; they facilitate communication between neurons by transmitting signals across synapses. Their primary function is to modulate brain activity, not energy storage.
B. Neurotransmitters are activated by the enzyme transferase. Neurotransmitters are not activated by transferase. They are synthesized, stored in vesicles, and released into the synaptic cleft in response to an action potential, where they bind to receptors to elicit a response.
C. Neurotransmitters function by inhibiting the production of glucose. Neurotransmitters do not inhibit glucose production. They play a role in neuronal signaling, affecting mood, cognition, and physiological processes, but do not directly regulate glucose metabolism.
D. Neurotransmitters are found throughout the body. Neurotransmitters exist in both the central and peripheral nervous systems, regulating various functions such as mood, movement, and autonomic responses. They are essential for communication between neurons in the brain and throughout the body.

Correct Answer is C
Explanation
A. "When attending dialectical behavior therapy." Dialectical behavior therapy (DBT) is specifically designed to help individuals with borderline personality disorder (BPD) manage emotions and reduce self-harming behaviors. While therapy can bring up distressing emotions, it provides structured support and coping strategies. The risk of self-harm is lower when clients are actively engaged in treatment and receiving professional guidance.
B. "When getting married." Major life changes, including marriage, can be stressful for individuals with BPD, but they do not inherently pose the highest risk for self-harm. Support from a partner and structured therapy can help navigate emotional challenges. While instability in relationships can trigger distress, the protective factors of marriage may reduce immediate risk. Self-harm risk is typically higher in periods of transition without support.
C. "When discharged from the hospital." Clients with BPD often struggle with emotional regulation, and discharge represents a significant transition with decreased support. The sudden loss of a structured inpatient setting can increase feelings of abandonment and distress, leading to a heightened risk of self-harm. Ensuring a follow-up care plan and support system is crucial to reducing this risk after hospitalization.
D. "When attending narrative therapy." Narrative therapy helps clients reframe their experiences and build a stronger sense of identity. Although deep emotional topics may be explored, structured therapy provides a safe space for expression. Therapeutic interventions aim to reduce distress and teach coping mechanisms, decreasing the likelihood of self-harm. The highest risk occurs when structured support is suddenly removed.
Correct Answer is B
Explanation
A. Tell the client that there is nothing there. Dismissing the client's perception may increase distress and reduce trust in the nurse-client relationship. A therapeutic approach acknowledges the client’s experience without reinforcing or denying hallucinations.
B. Ask the client to describe what is being seen. Encouraging the client to describe the hallucination helps assess its nature and severity. Understanding the content allows the nurse to provide appropriate support, ensure safety, and guide interventions.
C. Touch the client's arm reassuringly. Touching the client without consent, especially during a distressing hallucination, may escalate fear or agitation. Maintaining a calm and non-threatening presence is more appropriate.
D. Remove the client from the room. Relocating the client without assessing the hallucination may not address the underlying distress. Identifying triggers and using therapeutic communication are more effective initial interventions.
