A nursing instructor is teaching about the monoamine category of neurotransmitters. Which student statement indicates that learning about the function of norepinephrine has occurred?
- A. Norepinephrine functions to regulate mood, cognition, and perception.
- B. Norepinephrine functions to regulate arousal, libido, and appetite.D. Norepinephrine functions to regulate pain, inflammatory response, and wakefulness.
Correct Answer: B
Rationale: The correct answer is B because norepinephrine is primarily involved in regulating arousal, libido, and appetite. This neurotransmitter is released in response to stress or danger, increasing alertness and readiness for action. Choices A and C are incorrect because they describe the functions of serotonin and dopamine, respectively. Serotonin regulates mood, cognition, and perception, while dopamine is involved in pain modulation, inflammatory response, and wakefulness. Therefore, choice B is the most appropriate in indicating learning about the function of norepinephrine.

Which of the following symptoms should a nurse expect to assess in a client experiencing elevated levels of thyroid hormone? Select all that apply.
- A. Emotional lability
- B. Depression
- C. Insomnia
- D. Restlessness
Correct Answer: A

This is due to the impact of thyroid hormone on neurotransmitters in the brain. Depression (B) is more commonly associated with low thyroid hormone levels. Insomnia (C) can occur with both high and low thyroid hormone levels. Restlessness (D) is more indicative of hyperthyroidism, where there is excess thyroid hormone.
A nursing instructor is teaching about specific phobias. Which student statement should indicate that learning has occurred?

- C. These clients experience symptoms that mirror a cerebrovascular accident (CVA).
- D. These clients experience the symptoms of tachycardia, dysphagia, and diaphoresis.

Rationale: The correct answer is B because it accurately describes a key feature of specific phobias: individuals experience intense panic symptoms when exposed to the phobic stimulus. This indicates learning as it demonstrates understanding of the characteristic behavioral response in specific phobias. Choice A is incorrect as it describes characteristics of agoraphobia, not specific phobias. Choice C is incorrect as it describes symptoms of a stroke, not specific phobias. Choice D is incorrect as it lists symptoms that are not typically associated with specific phobias.
A female nurse is caring for a traditional Arab American male client. When planning effective care for this client, the nurse should be aware of which of the following cultural considerations? Select all that apply.

1. In traditional Arab American culture, limited touch is acceptable only between members of the same sex due to modesty and respect for personal boundaries.
2. This cultural consideration is important for the nurse to provide appropriate care that respects the client's cultural beliefs and preferences.
3. Understanding this aspect helps the nurse establish trust and build rapport with the male client while upholding cultural sensitivity and respect.
Summary:
- Choice B is incorrect as Arab American individuals may stand close and make eye contact during conversations.
- Choice C is incorrect as devout Muslim men may opt for not shaking hands with women due to religious beliefs, not solely based on gender.
- Choice D is incorrect as gender roles in traditional Arab American culture can vary and may not always follow a strict hierarchical structure.
A client is taking chlordiazepoxide (Librium) for generalized anxiety disorder symptoms. In which situation should a nurse recognize that this client is at greatest risk for drug overdose?
- A. When the client has a knowledge deficit related to the effects of the drug
- B. When the client combines the drug with alcohol
- C. When the client takes the drug on an empty stomach
- D. When the client fails to follow dietary restrictions
Correct Answer: B
Rationale: The correct answer is B: When the client combines the drug with alcohol. Combining chlordiazepoxide with alcohol can potentiate the central nervous system depression effects, leading to respiratory depression, sedation, and potential overdose. Alcohol can enhance the sedative effects of chlordiazepoxide, increasing the risk of overdose. A, C, and D are incorrect because a knowledge deficit, taking the drug on an empty stomach, or failing to follow dietary restrictions are not directly related to increasing the risk of drug overdose in this specific scenario.
A client refuses to go on a cruise to the Bahamas with his spouse because of fearing that the cruise ship will sink and all will drown. Using a cognitive theory perspective, the nurse should use which of these statements to explain to the spouse the etiology of this fear?
- A. Your spouse may be unable to resolve internal conflicts, which result in projected anxiety.
- B. Your spouse may be experiencing a distorted and unrealistic appraisal of the situation.
- C. Your spouse may have a genetic predisposition to overreacting to potential danger.
- D. Your spouse may have high levels of brain chemicals that may distort thinking.
Correct Answer: B
Rationale: The correct answer is B: Your spouse may be experiencing a distorted and unrealistic appraisal of the situation. This aligns with cognitive theory, which focuses on how our thoughts and perceptions influence our emotions and behaviors. In this case, the client's fear of the cruise ship sinking is likely based on an irrational and exaggerated belief rather than a realistic assessment of the situation.
Choice A is incorrect because it focuses on internal conflicts, which may not be directly related to the client's fear of the cruise ship sinking. Choice C is incorrect as genetic predisposition alone is unlikely to explain the specific fear of the cruise ship sinking. Choice D is incorrect as it suggests a biological basis for the fear, whereas cognitive theory emphasizes the role of thoughts and perceptions.
