NCLEX RN Exam Review Answers
1. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?
- A. The Programmed Longevity Theory
- B. The Immunological Theory of Aging
- C. The Endocrine Theory
- D. The Rate of Living Theory
Correct answer: B
Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.
2. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?
- A. Uncompensated respiratory acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic acidosis
- D. Compensated metabolic alkalosis
Correct answer: A
Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.
3. The nurse is discussing the need for early diagnosis and treatment of autism spectrum disorder (ASD) with parents of children suspected of having the condition. Which statement should the nurse include?
- A. Early diagnosis and treatment provide the only means for a cure of ASD.
- B. Early diagnosis and treatment gives your child the best chance of becoming a fully functioning adult.
- C. Early diagnosis and treatment provides the best way to ensure that your child can be admitted to an assisted living facility as an adult.
- D. Early diagnosis and treatment prevent your child from developing any other mental condition.
Correct answer: B
Rationale: The correct statement for the nurse to include is that early diagnosis and treatment provide the best chance for the child to become a fully functioning adult. It is important to educate parents that while early intervention can improve outcomes for individuals with ASD, it does not offer a cure but helps in managing symptoms and developing necessary skills. Choice A is incorrect as there is currently no cure for ASD. Choice C is inaccurate as early diagnosis and treatment focus on improving the child's quality of life and independence rather than ensuring admission to an assisted living facility. Choice D is incorrect as early diagnosis and treatment of ASD do not prevent the development of other mental health conditions; however, they can help in identifying and managing such conditions early on.
4. A 39-year-old woman presents for treatment of excessive vaginal bleeding after giving birth to twins one week ago. Which nursing diagnosis is most appropriate in this situation?
- A. Knowledge Deficit related to post-partum blood loss
- B. Self-Care Deficit related to post-partum neglect
- C. Fluid Volume Deficit related to post-partum hemorrhage
- D. Body Image Disturbance related to body changes after delivery
Correct answer: C
Rationale: The correct nursing diagnosis in this situation is 'Fluid Volume Deficit related to post-partum hemorrhage.' Post-partum hemorrhage can lead to excessive bleeding, putting the client at risk of fluid volume deficit due to the loss of blood volume. This diagnosis is most appropriate as it addresses the immediate concern of fluid loss. 'Knowledge Deficit related to post-partum blood loss' (Choice A) is incorrect as the priority in this case is addressing the physical issue of fluid volume deficit rather than knowledge deficit. 'Self-Care Deficit related to post-partum neglect' (Choice B) is not relevant to the situation described. 'Body Image Disturbance related to body changes after delivery' (Choice D) is not the most appropriate nursing diagnosis in this context where the primary concern is fluid volume deficit due to post-partum hemorrhage.
5. Upon admission to the stroke care unit of a rehabilitation center, what is the primary action of the nurse?
- A. Collect and organize documents for the client's medical record
- B. Prepare the client's identification bracelet
- C. Identify pertinent health history data and current needs and limitations
- D. Gather the client's valuables and secure them in a locked container
Correct answer: C
Rationale: When a client is admitted to a stroke care unit in a rehabilitation center, the nurse's initial priority is to assess the client. This assessment includes identifying relevant health history data that may impact the client's care. By recognizing the client's current needs and limitations, the nurse can develop a comprehensive understanding of the client's condition. This information is crucial for generating a nursing diagnosis and establishing appropriate care outcomes. While collecting and organizing documents for the medical record, preparing identification bracelets, and securing valuables are important tasks, they are not the primary actions that directly influence the client's immediate care upon admission.
