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 ["C","D","E"]
Explanation
A. Nylon socks. Nylon socks do not pose a significant risk for self-harm and can be safely kept with the client. They are not considered a ligature risk or a hazardous object.
B. Cotton underwear. Cotton underwear is not a safety concern in a mental health unit. It does not present a strangulation risk or any other immediate danger.
C. Lace-up tennis shoes. Lace-up shoes contain long laces that could be used as a ligature, posing a strangulation risk. Clients in a mental health unit are typically provided with slip-on or Velcro shoes to enhance safety.
D. Glass-framed picture of the client's partner. A glass frame poses a significant risk as it can be broken and used as a sharp object for self-harm. The nurse should ask the partner to take it home or provide a safer alternative, such as a laminated photo.
E. Necklace. A necklace can be used for strangulation, making it unsafe for a client at risk of self-harm. Removing items that could be used for ligature or harm is essential in suicide prevention.
