Nokea
A nurse concludes that a restless, agitated client is manifesting a fight-or-flight response. The nurse should associate this response with which neurotransmitter?
- A. Dopamine
- B. Serotonin
- C. Norepinephrine
Correct Answer: C
Rationale: The correct answer is C, Norepinephrine. During the fight-or-flight response, the sympathetic nervous system is activated, leading to the release of norepinephrine. Norepinephrine increases heart rate, blood pressure, and alertness, preparing the body to either fight or flee from a perceived threat. Dopamine (A) is more related to reward and pleasure. Serotonin (B) is involved in regulating mood and emotions. Cortisol (D) is a stress hormone, not a neurotransmitter involved in the fight-or-flight response.

Which client statement reflects an understanding of the effect of circadian rhythms on a person?
- A. When I dream about my mothers horrible train accident, I become hysterical. B. I get really irritable during my menstrual cycle.C. Im a morning person. I get my best work done in the a.m.
- B. Every February, I tend to experience periods of sadness.
Correct Answer: C
Rationale: The correct answer is C because the client statement "I'm a morning person. I get my best work done in the a.m." reflects an understanding of circadian rhythms. Circadian rhythms are the body's internal clock that regulates the sleep-wake cycle and influences energy levels and productivity throughout the day. Being a morning person indicates that this individual's peak productivity aligns with their body's natural circadian rhythm, which typically results in better performance during the morning hours.
Choice A is incorrect as it relates to a traumatic dream triggering hysteria, not circadian rhythms. Choice B is incorrect as it mentions experiencing sadness in February, which is more likely related to seasonal affective disorder rather than circadian rhythms.
A nurse should provide this information to facilitate which ethical principle?
- A. Autonomy
- B. Beneficence
- C. Nonmaleficence
- D. Justice
Correct Answer: A
Rationale: The correct answer is A: Autonomy. Autonomy refers to respecting an individual's right to make informed decisions about their own care. Providing information empowers patients to make autonomous decisions, aligning with this principle. Beneficence focuses on doing good for the patient, nonmaleficence on avoiding harm, and justice on fairness in resource allocation. While these are important ethical principles in healthcare, they do not directly relate to the act of providing information to support patient autonomy.
A nursing instructor is teaching about specific phobias. Which student statement should indicate that learning has occurred?
- A. These clients do not recognize that their fear is excessive, and they rarely seek treatment.
- B. These clients have overwhelming symptoms of panic when exposed to the phobic stimulus.
- C. These clients experience symptoms that mirror a cerebrovascular accident (CVA).
- D. These clients experience the symptoms of tachycardia, dysphagia, and diaphoresis.
Correct Answer: B
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.
According to Eriksons developmental theory, when planning care for a 47-year-old client, which developmental task should a nurse identify as appropriate for this client?
- A. To achieve a sense of self-confidence and recognition from others
- B. To reflect back on life events to derive pleasure and meaning
- C. To achieve established life goals and consider the welfare of future generations
Correct Answer: B
Rationale: In Erikson's theory, the developmental task for a 47-year-old client aligns with the stage of Generativity vs. Stagnation. Choice B, reflecting on life events for pleasure and meaning, corresponds to this stage where individuals assess their accomplishments and seek fulfillment. This phase involves contributing to society and future generations. Choice A pertains to the earlier stage of Identity vs. Role Confusion in adolescence. Choice C aligns with the later stage of Integrity vs. Despair in older adulthood. Choice D is incomplete. Therefore, the correct answer is B as it best fits the age and developmental stage of the client in question.
A newly admitted client diagnosed with obsessive-compulsive disorder (OCD) washes hands continually. This behavior prevents unit activity attendance. Which nursing statement best addresses this situation?
- A. Everyone diagnosed with OCD needs to control their ritualistic behaviors.
- B. It is important for you to discontinue these ritualistic behaviors.
- C. Why are you asking for help if you wont participate in unit therapy?
- D. Lets figure out a way for you to attend unit activities and still wash your hands.
Correct Answer: D
Rationale: The correct answer is D because it acknowledges the client's need to wash their hands due to OCD while also addressing the issue of missing unit activities. By suggesting finding a way for the client to attend activities while still accommodating their need to wash hands, it promotes a collaborative approach and respects the client's autonomy. Option A is incorrect as not everyone with OCD can completely control their behaviors. Option B is too directive and may increase resistance. Option C is confrontational and may discourage the client from seeking help.
