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 A
Explanation
A. "Avoid looking at other clients on the unit." Distractions reduce the quality of communication and make the client feel undervalued. Focusing on the client demonstrates attentiveness and encourages open dialogue. Looking at others while a client speaks may suggest disinterest. Giving full attention strengthens therapeutic relationships and supports effective listening.
B. "Interrupt the client's statement to clarify thoughts or ideas." Interrupting can disrupt the client’s thoughts and make them feel unheard. Active listening requires patience, allowing the client to speak fully before responding. Clarifications should be made after they finish to ensure understanding. Frequent interruptions may hinder trust and open communication.
C. "Show emotion when a client is disclosing sensitive information." While empathy is important, excessive emotional reactions can shift focus away from the client. A calm and composed demeanor helps maintain a supportive environment. Overreacting may make the client feel uncomfortable or hesitant to share. Active listening involves offering validation without overwhelming emotional responses.
D. "Keep direct eye contact to a minimum." Eye contact conveys attentiveness and respect, helping to establish rapport. Avoiding eye contact may make the client feel ignored or dismissed. However, excessive staring can be intimidating, so a balanced approach is best. Appropriate eye contact fosters trust and enhances communication.
Correct Answer is A
Explanation
A. Splitting is a defense mechanism commonly used by clients with borderline personality disorder. It involves viewing people or situations as entirely good or entirely bad, leading to rapidly shifting opinions and emotional reactions. This black-and-white thinking can create division among healthcare providers, as the client may idealize one staff member while devaluing another, causing conflict within the team.
B. Reaction formation occurs when a person expresses the opposite of their true feelings, often due to discomfort with their actual emotions. While seen in some personality disorders, it is not a hallmark feature of borderline personality disorder and does not typically contribute to team division.
C. Denial involves refusing to acknowledge reality or facts that cause distress. Though common in various mental health conditions, it does not specifically create division among healthcare providers in the way splitting does. Clients with borderline personality disorder may use denial, but it is not their primary defense mechanism.
D. Regression is a defense mechanism where an individual reverts to earlier developmental behaviors in response to stress. While it can be seen in borderline personality disorder, it does not typically lead to splitting within the healthcare team, as it primarily affects the client’s own coping mechanisms rather than interpersonal dynamics.
