HESI LPN

1. What are neurotransmitters?

A. Chemical messengers that cause brain cells to turn on or off.
B. Areas of the brain that are responsible for controlling emotions.
C. Clumps of cells that alert the other brain cells to receive messages.
D. Web-like structures that provide connections among parts of the brain.

Correct answer: A

Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.

2. A client with a leg amputation is upset about his appearance. The LPN/LVN intends to address which most closely associated psychosocial problem?

A. Inability to be mobile
B. Isolating self from others
C. Inability to tolerate activity
D. Concern about body persona

Correct answer: D

Rationale: The correct answer is D. A client with a leg amputation being upset about his appearance is most closely associated with concerns about body image and self-perception. This individual may be worried about how others perceive them, impacting their self-esteem and overall well-being. Choices A, B, and C are incorrect because the primary psychosocial issue in this scenario is related to body image and self-perception, not mobility, social isolation, or activity tolerance.

3. A female client with schizophrenia is experiencing auditory hallucinations. What is the most therapeutic response by the nurse?

A. I don't hear any voices. They must be in your head.
B. What are the voices telling you to do?
C. You need to ignore the voices and focus on reality.
D. I know the voices are real to you, but I don't hear them.

Correct answer: D

Rationale: Acknowledging the client's experience while gently presenting reality can help build trust and provide reassurance without reinforcing the hallucination.

4. The wife of a male client recently diagnosed with schizophrenia asks the nurse, 'What exactly is schizophrenia? Is my husband all right?' Which response is best for the LPN/LVN to provide to this family member?

A. It sounds like you're worried about your husband. Let's sit down and talk.
B. It is a chemical imbalance in the brain that causes disorganized thinking.
C. Your husband will be just fine if he takes his medications regularly.
D. I think you should talk to your husband's psychologist about this question.

Correct answer: B

Rationale: The best response for the LPN/LVN to provide to the wife of a male client diagnosed with schizophrenia is choice B: 'It is a chemical imbalance in the brain that causes disorganized thinking.' This response educates the wife about the nature of schizophrenia, explaining that it is caused by a chemical imbalance in the brain leading to disorganized thinking, helping her understand the condition better. Choice A does not directly address the question and instead shifts the focus to a different aspect. Choice C gives false reassurance without providing necessary information about schizophrenia. Choice D deflects the responsibility of providing information to the psychologist instead of addressing the wife's concerns directly.

5. A woman brings her 48-year-old husband to the outpatient psychiatric unit and describes his behavior to the admitting nurse. She states that he has been sleepwalking, cannot remember who he is, and exhibits multiple personalities. The nurse knows that these behaviors are often associated with

A. dissociative disorder.
B. obsessive-compulsive disorder.
C. panic disorder.
D. post-traumatic stress disorder.

Correct answer: A

Rationale: The correct answer is A: dissociative disorder. Sleepwalking, amnesia, and multiple personalities are examples of detaching emotional conflict from one's consciousness, which is the definition of a dissociative disorder. Obsessive-compulsive disorder (B) is characterized by persistent, recurrent intrusive thoughts or urges (obsessions) and compulsions. Panic disorder (C) is characterized by acute attacks of anxiety. Post-traumatic stress disorder (D) involves re-experiencing psychologically distressing events.
